Nice how you incorporated one of the most known items in a dental office into your own work space. The fact you gave the back story makes it even more beautiful.
Always love the scrapyard finds and fixes. Where possible, I use the older equipment, as it's so much better made and as you said less complicated, so less to go wrong.
@Repair Wins I've been doing the same for a while, it's great to see the happy faces of people when you repair something. I also get brought the more complicated things or stuff that needs welding etc to my home, as they know I'll give anything a go at repairing.
I have built countless dental offices in my career, those Siemens E1 dental chairs were some of my earliest that I worked upon at the beginning of my work life.

22:43 Hats off to anyone who can decipher whatever the hell is going on in there. The last time I've learned about circuits was in physics class in 5th grade so the only thing I can confidently say is "It seems to be running on some sort of electricity".
You sure need some time to understand whats going on in these plans but if you got the basics, its doable. Especially if you got an old plan like this, where the function of each part of the circuit is named. Especially in radios and such you can do it by normally just by following the signal. But i guess it is easy for me to say that as I work in developing measuring equipment, even when its more in "testing and bug fixing" than designing the circuits.
@@Ckay2552 i hear you there. love to find out which little bugger is causing the problem. but don't tell everyone we know the secerets... i need my job. =o) just tell them the magic smoke just came out of it. lol

If you replace the filter caps on a vintage amp that has a large grill on the top and you don't it looking empty, a trick is to empty out the original caps and hide the new ones inside. They often have tabs to remove the bottom. Bend em up and pull the bottom out along with the innards, then cut the connections between the windings and the terminals. Solder on leads from the terminals to those on your replacements, mount the new caps on the bottom piece, and put it back inside the old can. Viola! Looks like a vintage amp again, complete with chunky filter caps!

When he whips out that surgical lamp you know shits about to go down. Its crazy to think how many teeth were fixed over all those years from the light that one lamp provided.
Don't know if you can get it locally in Germany, but there's a product called Deoxit that basically fixes 99% of dirty crackling potentiometers.. Just spray it in, work the potentiometer around a few times, spray again to flush, then let the part dry and in the vast majority of cases, the pot works fine again. The only thing it can't fix is where the carbon has literally been worn off.. The stuff is very economical to use and I've had the same can for over 10 years and it has fixed many slide switches and noisy potentiometers...
Yes you can get it here in Germany. Music Store and Thomann (big online sellers of musical instruments and audio gear) got in in stock. Caig DeOxit D5 or maybe the Fader F5 might be even better for the job. 25€/can is very steep - but as you said - it's very economical in use!
That dental chair is a Siemens Sirona M1. After my graduation as a DMD, I had a mandatory 6 month apprenticeship, which I finished at the Military Medical Academy in Belgrade. The dental clinic there had many of those M1s which were installed when the hospital opened in 1984. They still work today, and judging by the words of the repairmen, they are quite easy to maintain and repair, should they stop working. I remember them being quite comfortable too, much more so than modern Chinese dental chairs. Yugoslavian, and later Serbian factory of dental equipment "Jugodent" used to make those same lamps under the Siemens licence for their Elektra 2000 chairs.

1:00 I wish I had a scrapyard like that near me, I'd be down there every week looking for stuff. We do have scrapyards, but they take your stuff and give you money, but it all just gets melted down. No way to scavenge anything cool.

not that easy because the reflector is a parabolic type that relys on the 360° beam pattern of a halogen filament in the focuspoint. with led you cant have 360° beam in a small spot AND provide enogh cooling.
Worn or dirty contacts would have been my first suspicion on that old Fluke meter . I have fixed a lot of remote controls and other equipment with similar controls , just by cleaning with IPA and a cotton swab . I love that old lamp and how you repurposed it . Scrapyards are always interesting , full of endless possibilities for anyone with some tools and imagination .
I repaired a digital products remote today using those same products. It had not worked for over a decade! (I tend to think a Q tip inside those buttons and a good scrubbing of the PCB with a #2 pencil's eraser would have made that Fluke work again w/o the new board purchase)
I repair a lot of playstation controllers and moře often than not, the carbon from the flexible board completely flakes off and the whole board has to be replaced.

So great to know there are still some smart people left in this world. Your skills will help rebuild the world WSHTF. Seriously your level of knowledge is very impressive. Thank you for sharing . Be safe on your trip.
I love that old-style hi-fi construction. One of my buddies brought back a unit from overseas when he was in the military back in the 90s, and that thing was awesome! It was very heavy, and had incredible power.
Adam Savage has a cool project to make a light source on a bendable arm but everytime he moves it, it makes a terrible creaking noise. The lamp in this vid is so sweet and smooth. Well done as always!
Fader cleaner is what you want to clean pots. Normal Deoxit or contact cleaner may not work and can even make it worse. Worth a shot trying to restore the original pots.
I love the amplifier repairs in this series. I recently found an old Realistic stereo amp and the RCA ports on the back had broken their connections off the circuit board. Even with my almost complete lack of knowledge when it comes to electronic devices I was able to re-solder them and fix the amp! Thanks for the excellent content.
So true. We bought an expensive and complicated coffee maker. It lasted 8 months. Now we use the old one, easy and it always works. I enjoy your videos very much.
Great Job on fixing the Ultrasonic Cleaner. I had a feeling it would have been the mosfets. I've replaced quite a few over the years, and more recently on some Milwaukee Tools I've been repairing on my channel. I had the same problem with needing a longer screwdriver (well torx) when recently repairing a milwaukee jobsite radio.
Reed Richards, The Leader and Dr. Doom ain't got nothing on you! You are the man. I don't know how you find repair/replacement parts, but you got skills! Keep doing what you are doing.
Another thing the items on this channel were built for were to last a lifetime and built to be serviced/repaired! This I way I love old things like tools and equipment, modern things are just consumerist trash that break quickly and aren't meant to be repaired, just thrown away and repurchased. Great video as always, thank you for uploading! 👍👍
Back in the early '90's at Technical collage I bought a long screwdriver for exactly the same purpose.....oh and they taught us how to fix electronics back then.
Beautiful Luxman! I got a PD370 turntable with a vacuum pump that's supposed to help with warped disks by sucking them and making them flat against the platter.
lamp is really neat! but i think the box shouldnt be taking workspace and the lamp should be mounted higher, maybe add some higher 2x4 to the back of the workbench and attach the lamp to that?
Your Luxman repair brought me back to one I did a few years ago, a later model, possibly early 80's. I ended up replacing every single cap (about 30 or so) and 2 faulty power transistors. A really rewarding experience getting the thing going again for the customer. I really dig the dentist lamp you have, would like to replicate that arm in my own workshop.
The front metal piece of the Luxman amp is a beauty. All sorts of switches designed to their job, everything in the right place, boldly engraved features, timeless font, not pretending anything.
Great job with the fixes! My car's Sub woofer was the same story, large rockford fosgate and housing from the dump, I simply epoxied the magnet back together, my amp was also from the dump and only needed a couple new capacitors that I salvaged from another much older amp that had been smashed, My aftermarket speakers where from a wreck at the crusher and the only part I paid for apart from the Atoto double din stereo. I should record some of my find's and upload them!
I would've taken the old caps housings and 3d print reductions to reuse them and hide new caps inside. I know that you don't see them normally but... I've done in on some of my amplifiers and it just looks and feels better :>
That lamp is amazing - wonderful that you brought it back to good use. Really like that blue tooth speaker - the lights are wild and the speaker drivers look pretty powerful. Really cool to see the restoration of the 1970's amp as well - very cool!
Thank you for another great scrap yard trip. I really enjoy tagging along and finding some amazing finds. Wish I was there sometimes. I sure miss my trips to the junk yard on Sundays. Alrighty enough said. Take care from Canada eh!
I had a bad pot on a 1980s Radio Shack scanner radio. I cleaned it over and over again. It was still failing. I finally opened it up and usually the wipers consist of 2 or 3 fingers touching the resistive trace. There was definitely a worn spot on the trace. It dawned on me to slightly bend the wipers over to a non worn part of the trace. It has worked fine now for a decade. That solved my problem. I love this series. I never miss it!!!!!
Wow, I purchased that exact Fluke model when I set up a lab when I first started work in 97. Had completely forgotten about it. Nice to see that the gear I brought may have lasted a while, if well taken care of.
good fixes ....enjoy your films and attitude to the modern world... your statement about older machines being 'robust and simple' is so true. keep up the good work.
I have a Lux 507 of similar vintage which powers our formal Living room (a room virtually never used) and still love that amp. When I first got it, it had a variable level of distortion which we tracked down to Very bad power (in the wall) which we tracked down to a sparking breaker in the fuse box. Saved us from a fire I am sure. At the time it was claimed to have the lowest distortion level of any amplifier and if you put it on an oscilloscope you wound up measuring the scope’s distortion. Probably surpassed easily now but as a college student it was a serious source of pride. Can’t bring myself to part with it. Have a Lux cassette player (!) of the same vintage to keep it company.
Little tip when repairing speakers use a playing card or thin material as a spacer so that the voice coil is centred properly in the magnet. Great content, Posh work 👌
@@ppdan A wide gap for low efficiency. A wide gap to hold a lot of metal filings sucked in by the magnet that were not cleaned out. A wide gap that might provide clearance for the bent up voice coil, BUT that wide gap between pole faces is still probably around 0.5 to 0.75 mm each side of the coil. Yeah, cheap and junk.... better to just wire stereo inputs as mono, disconnect the wiring to voice coil on deadie and let it run as a passive radiator.
I had initially thought perhaps the Aldi BT boombox sounded unacceptably tinny (to me) but then when you used the proper audio amplifier I realized that this is an artifact of how the sound was recorded. Excellent job!
Love the junk yards, always something nice to find. Also be careful not to run ultrasonic cleaners dry, permanent damage to the transducers will occur. They need to be filled to the indicator mark in the basin and another way to test the unit is to float a piece of aluminium foil in the solution and run the unit for say 5 minutes, the foil should disintegrate if the unit is working normally.
That fluke meter must've been expensive when new! In '99 when I was in college, the fluke rep came by to show off the Fluke 98 multimeter. I couldn't afford one, but one or two other students fell into that trap!
Afaik, our scrapyards here in the Philippines are gleaned dry of repairable and salvagable materials. No metals as they are reused for something else. No repairable electronics as there's always a waiting repairman there who would take the components home to make it work to make them his own. Only there left are wood and plastics as they are difficult to reuse or recycle.
hi, usable scrap yard findings are the downside to developed and low income difference society. I have Ms.C in engineering and I make 32€/h minus 30% income tax. For repair guy I need to pay about 60-100€ per hour (car repair being at top end). I follow TPAI because it's fascinating and I learn to save money since practically it's impossible to find repair guy or it costs too much to make any economical sense.
As always, incredibly interesting content young sir. You did incite a hearty chuckle when describing the attendees of the Dental Surgery 'opening ceremony' as "incredibly German". Always interesting, long may your channel's success continue to grow!
It would be great to see you when you come to the UK but unfortunately I'm based in Leeds. You're channel has definitely been an inspiration to my own builds and salvage/repair efforts
The new screw driver seems a bit wasteful because you still have a spare 13cm even when fully engaged with the screw. Joking aside this is yet another fantastic video and after only 5 hours on youtube almost 20k views. You made it man you have a BIG FANBASE and we love your stuff.
You have certainly encouraged me. I am cleaning out a store room and found a 4" Makita Angle grinder. It is stuck (won't rotate) but I will see if I can get it working again.
making a note of the trick of using ordinary washing powder! That's not one I've come across although in hind-sight I should've thought of that. I use a mix of vinegar and liquid soap, and throw in a teaspoon or so of bicarbonate so the fizz lifts the dirt. Using washing powder, which is alkali, would improve that. Your're not wrong with comments about complexity... to Quote Scotty from Star Trek: "the more they over-think the plumbing, the easier it is to stop up the drain!"
As always my man, great video and keep on doin what you do. Youve inspired me 2 years ago. I am a woodartist and with your scrapyard vids i came to the conclusion that that was all i needed. I started visiting local scrapyards here in South Holland, and untill this day i produce all off my artwork with 90 prcnt scrapyardfinds. If there is a day you visit your western neighbours and theres some time left in your agenda, i would love to show you my way of desinging art. Can't thank you enough for your effort with making these vids. You really helped me
Nice work on the amp repair! I have an old Technics SA700-A tuner/amp (100 watts RMS per channel), from 1978 that needs a similar treatment. It still works but the pots and most of the switches need serious cleaning and/or replacement. I hate to just throw it out, since it has fantastic performance when it IS working. It's a real boat anchor, weighing in around 35 lbs. (16.1 kg), but most of that is the massive transformer inside! Hopefully I can get it out from my back room and back in operation in the near future!😄👍
On that dental lamp front center wheel can be turned to adjust light intenisity, it works mechanicly by partialy obscuring the light bulb. It's usualy stuck becose everyone kept it at maximum for decades. Also focus can be adjusted to get perfect rectangle light on the surface at 1m distance by removing back cap held by the spring coil and pulling bulb socket in and out by hand, bulb can also be replaced from the back without disassembling the lamp. I still see them in use to this day and osram and philips still make 24v 150w bulbs for them.
I would really appreciate and enjoy a video about connecting and operating an oscilloscope. I have a nice HP unit that works but was going to be discarded. I found a generic set of hook-ups for sale on Amazon and grabbed those. I know a very little bit about Oscilloscopes and really want to learn more about them. I am into Ham radio and the scopes are a great thing for testing and setting up radio equipment and components. I know there are videos out there but the TPAI films are very easy for me to follow and understand. Nice work on saving the Lamp! I need to learn more about the 3D printing process as well but that's another road... Take Care and have a great trip, John
Great stuff mate. I live in a small town that has a local dump where I find all sorts of good things very cheaply, sometimes free. Half the stuff in my house comes from the dump or second hand thrift stores.😁
Too true , we are seeing dividends from overcomplex stuff! You are so spot on ! I love what you are producing. I can't get over some of the stuff that is wasted.
Danke für deine tollen und inspirierenden Videos. Hast du schonmal über Holzgasproduktion und das Betreiben eines Stromgenerators nachgedacht? Wäre sicher ein interessantes Video/Videoreihe da man sich mit dem Stromgenerator vom Schrott/ebay, dem Holzgasgenerator aus Fässern und Gasflaschen und dem richtigen Brennstoff und dessen Gewinnung mit einem z.B. Gartenhächsler beschäftigen kann. Wenn du keine Zeit oder Interesse für sowas hast ist das natürlich auch völlig verständlich. Das Thema ist im Moment für mich sehr interessant, da eigenen Strom zu erzeugen in Zukunft nützlich sein könnte und man eventuell nicht immer an Benzin oder Diesel kommt... Bitte mach weiter so mit dem was du tust.

Electric heater bracket from stuff off the yard . and found a nice couple of wire baskets for the garage for storing my air hoses total cost.. 10 euro xD and healthy walk back and forth :P
Love your videos as always. I hope someday soon you find a horizontal bandsaw to help cut down on your use of the angle grinder lol. You have shown me that the tool to test the mosfets is worth buying. Iv had to toss a few sonic cleaners over the years.

So great to know there are still some smart people left in this world. Your skills will help rebuild the world WSHTF. Seriously your level of knowledge is very impressive. Thank you for sharing . Be safe on your trip.
I love that old-style hi-fi construction. One of my buddies brought back a unit from overseas when he was in the military back in the 90s, and that thing was awesome! It was very heavy, and had incredible power.
The world needs more people like you. 👍👍👍
Always a pleasure to watch you work.
Adam Savage has a cool project to make a light source on a bendable arm but everytime he moves it, it makes a terrible creaking noise. The lamp in this vid is so sweet and smooth. Well done as always!
best channel over here always nice to hear the first minute and your general thinking about the era we live in.
Nothing beats a knob deep cleaning 😂
Fader cleaner is what you want to clean pots. Normal Deoxit or contact cleaner may not work and can even make it worse. Worth a shot trying to restore the original pots.
I really like what you did with the dental lamp. Very unique and useful.
I love the amplifier repairs in this series. I recently found an old Realistic stereo amp and the RCA ports on the back had broken their connections off the circuit board. Even with my almost complete lack of knowledge when it comes to electronic devices I was able to re-solder them and fix the amp! Thanks for the excellent content.
So true. We bought an expensive and complicated coffee maker. It lasted 8 months. Now we use the old one, easy and it always works. I enjoy your videos very much.
Great Job on fixing the Ultrasonic Cleaner. I had a feeling it would have been the mosfets. I've replaced quite a few over the years, and more recently on some Milwaukee Tools I've been repairing on my channel. I had the same problem with needing a longer screwdriver (well torx) when recently repairing a milwaukee jobsite radio.
You found a Luxman 309 integrated amplifier, 75 watt RMS per channel. What a great find. I wonder if the person who threw ii away knew its value.
Reed Richards, The Leader and Dr. Doom ain't got nothing on you! You are the man.
I don't know how you find repair/replacement parts, but you got skills!
Keep doing what you are doing.
Dentist light is the highlight. Well done. Just a reminder, it might be too bright for you to look at objects illuminated by it for too long.
Another thing the items on this channel were built for were to last a lifetime and built to be serviced/repaired! This I way I love old things like tools and equipment, modern things are just consumerist trash that break quickly and aren't meant to be repaired, just thrown away and repurchased.
Great video as always, thank you for uploading! 👍👍
Back in the early '90's at Technical collage I bought a long screwdriver for exactly the same purpose.....oh and they taught us how to fix electronics back then.
Good old days now we can’t even tell if we’re male or female, wtf has this world come to, sad really
Beautiful Luxman! I got a PD370 turntable with a vacuum pump that's supposed to help with warped disks by sucking them and making them flat against the platter.
lamp is really neat! but i think the box shouldnt be taking workspace and the lamp should be mounted higher, maybe add some higher 2x4 to the back of the workbench and attach the lamp to that?
Your Luxman repair brought me back to one I did a few years ago, a later model, possibly early 80's. I ended up replacing every single cap (about 30 or so) and 2 faulty power transistors. A really rewarding experience getting the thing going again for the customer.
I really dig the dentist lamp you have, would like to replicate that arm in my own workshop.
I am reminded each time that I return to your channel, how unique and enjoyable your style and perspective are. Thank you.
The front metal piece of the Luxman amp is a beauty. All sorts of switches designed to their job, everything in the right place, boldly engraved features, timeless font, not pretending anything.
Great job with the fixes! My car's Sub woofer was the same story, large rockford fosgate and housing from the dump, I simply epoxied the magnet back together, my amp was also from the dump and only needed a couple new capacitors that I salvaged from another much older amp that had been smashed, My aftermarket speakers where from a wreck at the crusher and the only part I paid for apart from the Atoto double din stereo. I should record some of my find's and upload them!
grrrrr i wish there were more scrapyards everywhere. I'd make my entire life a living off fixing/modfying/reselling scrap!! Aaaaa
I would've taken the old caps housings and 3d print reductions to reuse them and hide new caps inside. I know that you don't see them normally but... I've done in on some of my amplifiers and it just looks and feels better :>
That is a great idea!
That lamp is amazing - wonderful that you brought it back to good use. Really like that blue tooth speaker - the lights are wild and the speaker drivers look pretty powerful. Really cool to see the restoration of the 1970's amp as well - very cool!
Fine toolbox at 0.53. I have a dentist’s lamp in my workshop too!
I saw that toolbox as well!
Thank you for another great scrap yard trip. I really enjoy tagging along and finding some amazing finds. Wish I was there sometimes. I sure miss my trips to the junk yard on Sundays. Alrighty enough said. Take care from Canada eh!
I love the variety of the things you find and fix. It's very inspirational, and reduces my own fears of pulling apart electrical devices!
I had a bad pot on a 1980s Radio Shack scanner radio. I cleaned it over and over again. It was still failing. I finally opened it up and usually the wipers consist of 2 or 3 fingers touching the resistive trace. There was definitely a worn spot on the trace. It dawned on me to slightly bend the wipers over to a non worn part of the trace. It has worked fine now for a decade. That solved my problem. I love this series. I never miss it!!!!!
Wow, I purchased that exact Fluke model when I set up a lab when I first started work in 97. Had completely forgotten about it. Nice to see that the gear I brought may have lasted a while, if well taken care of.
Loved the Luxman repair. Great amp. Perhaps an Alps BlueVelvet or similar vol pot.
good fixes ....enjoy your films and attitude to the modern world... your statement about older machines being 'robust and simple' is so true. keep up the good work.
I have a Lux 507 of similar vintage which powers our formal Living room (a room virtually never used) and still love that amp. When I first got it, it had a variable level of distortion which we tracked down to Very bad power (in the wall) which we tracked down to a sparking breaker in the fuse box. Saved us from a fire I am sure. At the time it was claimed to have the lowest distortion level of any amplifier and if you put it on an oscilloscope you wound up measuring the scope’s distortion. Probably surpassed easily now but as a college student it was a serious source of pride. Can’t bring myself to part with it. Have a Lux cassette player (!) of the same vintage to keep it company.
Little tip when repairing speakers use a playing card or thin material as a spacer so that the voice coil is centred properly in the magnet. Great content, Posh work 👌
Luckily those cheap speakers have a huge gap.
@@ppdan A wide gap for low efficiency.
A wide gap to hold a lot of metal filings sucked in by the magnet that were not cleaned out.
A wide gap that might provide clearance for the bent up voice coil, BUT that wide gap between pole faces is still probably around 0.5 to 0.75 mm each side of the coil.
Yeah, cheap and junk.... better to just wire stereo inputs as mono, disconnect the wiring to voice coil on deadie and let it run as a passive radiator.
@@BTW... I am pretty sure it's more than 0.75mm between poles. It's probably 0.5mm between coil and poles which is huge.
one among the best stuff on tube. nice to see that vintage beauty restored.
I love this stuff, theres just nobody else on youtube who really does stuff the way you do
I had initially thought perhaps the Aldi BT boombox sounded unacceptably tinny (to me) but then when you used the proper audio amplifier I realized that this is an artifact of how the sound was recorded. Excellent job!
Love the junk yards, always something nice to find. Also be careful not to run ultrasonic cleaners dry, permanent damage to the transducers will occur. They need to be filled to the indicator mark in the basin and another way to test the unit is to float a piece of aluminium foil in the solution and run the unit for say 5 minutes, the foil should disintegrate if the unit is working normally.
Another wonderful installment to one of the best series on the platform. Thank you.
That fluke meter must've been expensive when new! In '99 when I was in college, the fluke rep came by to show off the Fluke 98 multimeter. I couldn't afford one, but one or two other students fell into that trap!
Afaik, our scrapyards here in the Philippines are gleaned dry of repairable and salvagable materials. No metals as they are reused for something else. No repairable electronics as there's always a waiting repairman there who would take the components home to make it work to make them his own. Only there left are wood and plastics as they are difficult to reuse or recycle.
hi, usable scrap yard findings are the downside to developed and low income difference society. I have Ms.C in engineering and I make 32€/h minus 30% income tax. For repair guy I need to pay about 60-100€ per hour (car repair being at top end). I follow TPAI because it's fascinating and I learn to save money since practically it's impossible to find repair guy or it costs too much to make any economical sense.
As always, incredibly interesting content young sir.
You did incite a hearty chuckle when describing the attendees of the Dental Surgery 'opening ceremony' as "incredibly German".
Always interesting, long may your channel's success continue to grow!
It would be great to see you when you come to the UK but unfortunately I'm based in Leeds. You're channel has definitely been an inspiration to my own builds and salvage/repair efforts
Very cool man. The part with your father n law really speaks to who you are. Bravo amigo.
Beautiful. A lot of complicated things works month and a lot of simple ones works years or decades.
The new screw driver seems a bit wasteful because you still have a spare 13cm even when fully engaged with the screw.
Joking aside this is yet another fantastic video and after only 5 hours on youtube almost 20k views.
You made it man you have a BIG FANBASE and we love your stuff.
You have certainly encouraged me. I am cleaning out a store room and found a 4" Makita Angle grinder. It is stuck (won't rotate) but I will see if I can get it working again.
making a note of the trick of using ordinary washing powder! That's not one I've come across although in hind-sight I should've thought of that. I use a mix of vinegar and liquid soap, and throw in a teaspoon or so of bicarbonate so the fizz lifts the dirt. Using washing powder, which is alkali, would improve that.
Your're not wrong with comments about complexity... to Quote Scotty from Star Trek: "the more they over-think the plumbing, the easier it is to stop up the drain!"
As always my man, great video and keep on doin what you do. Youve inspired me 2 years ago. I am a woodartist and with your scrapyard vids i came to the conclusion that that was all i needed.
I started visiting local scrapyards here in South Holland, and untill this day i produce all off my artwork with 90 prcnt scrapyardfinds.
If there is a day you visit your western neighbours and theres some time left in your agenda, i would love to show you my way of desinging art.
Can't thank you enough for your effort with making these vids.
You really helped me
I would have like to have seen you do something with whatever had those caterpillar tracks .
Had the same problem so I welded a longer section on a already long screwdriver for jobs like that Bluetooth speaker. Have a great visit to the UK!
Great to hear you are coming to UK! I'm a bit too far SW, but I'm sure there will be lots of chaps with sheds to make you welcome.
Another great episode! Loved the bluetooth speaker! Light show was an unexpected bonus!
Light up the hookah.
I just did a similar repair on a Bluetooth speaker I found that broke. Always great to see your videos, they really inspire me!
Wunderbar, I enjoy watching this series.
Hello TPAI! Just wanted to say that paint thinner (especially cheap ones) works well for removing glue.
Nice work on the amp repair! I have an old Technics SA700-A tuner/amp (100 watts RMS per channel), from 1978 that needs a similar treatment. It still works but the pots and most of the switches need serious cleaning and/or replacement. I hate to just throw it out, since it has fantastic performance when it IS working. It's a real boat anchor, weighing in around 35 lbs. (16.1 kg), but most of that is the massive transformer inside! Hopefully I can get it out from my back room and back in operation in the near future!😄👍
On that dental lamp front center wheel can be turned to adjust light intenisity, it works mechanicly by partialy obscuring the light bulb. It's usualy stuck becose everyone kept it at maximum for decades. Also focus can be adjusted to get perfect rectangle light on the surface at 1m distance by removing back cap held by the spring coil and pulling bulb socket in and out by hand, bulb can also be replaced from the back without disassembling the lamp. I still see them in use to this day and osram and philips still make 24v 150w bulbs for them.
I would really appreciate and enjoy a video about connecting and operating an oscilloscope. I have a nice HP unit that works but was going to be discarded. I found a generic set of hook-ups for sale on Amazon and grabbed those. I know a very little bit about Oscilloscopes and really want to learn more about them. I am into Ham radio and the scopes are a great thing for testing and setting up radio equipment and components. I know there are videos out there but the TPAI films are very easy for me to follow and understand.
Nice work on saving the Lamp! I need to learn more about the 3D printing process as well but that's another road...
Take Care and have a great trip, John
That Grundig may have been a great thing to fix
I stare at that same lamp every time I get my teeth cleaned. The blueprint would be nice in a frame. Thanks for the video and Happy Weltschmertz!
Great stuff mate. I live in a small town that has a local dump where I find all sorts of good things very cheaply, sometimes free.
Half the stuff in my house comes from the dump or second hand thrift stores.😁
Too true , we are seeing dividends from overcomplex stuff! You are so spot on ! I love what you are producing. I can't get over some of the stuff that is wasted.
Danke für deine tollen und inspirierenden Videos. Hast du schonmal über Holzgasproduktion und das Betreiben eines Stromgenerators nachgedacht? Wäre sicher ein interessantes Video/Videoreihe da man sich mit dem Stromgenerator vom Schrott/ebay, dem Holzgasgenerator aus Fässern und Gasflaschen und dem richtigen Brennstoff und dessen Gewinnung mit einem z.B. Gartenhächsler beschäftigen kann. Wenn du keine Zeit oder Interesse für sowas hast ist das natürlich auch völlig verständlich. Das Thema ist im Moment für mich sehr interessant, da eigenen Strom zu erzeugen in Zukunft nützlich sein könnte und man eventuell nicht immer an Benzin oder Diesel kommt...
Bitte mach weiter so mit dem was du tust.
That hardware store looks awesome!
ywah, all the neat Wiha stuff!
That dentist light ... what a score. Im jealous, would Love to have one of those, i have a total crap desk light that barely does the job . Very nice mate .
That lamp has seen many a rotten tooth, and has burned itself into the memory of countless scared townsmen and townswomen 👀
This channel is such a eye opener the day i first looked at it. ! atm finances are terrible . but the scrap yards are awesome to tinker . so far build my own. Electric heater bracket from stuff off the yard . and found a nice couple of wire baskets for the garage for storing my air hoses total cost.. 10 euro xD and healthy walk back and forth :P
I was hoping you would take that green toolbox in the beginning. I would love to find one of those!!
So was I! But Gerolf is probably very tired of looking at toolboxes after last year's effort to ship out so many for the holidays. 😆
Love your videos as always. I hope someday soon you find a horizontal bandsaw to help cut down on your use of the angle grinder lol. You have shown me that the tool to test the mosfets is worth buying. Iv had to toss a few sonic cleaners over the years.
I never find cool stuff at my scrap yard. It’s all sent to e-waste. The search continues! It’s a great hobby tho. Thank you from Texas U.S.A.
