That dry non-stop goofy humor in that German accent gets me every time.
Even I as a German find it nice.
German humour is no laughing matter
"For your everyday scraping needs" got me
Wenn ist das Nunstück git und Slotermeyer? Ja! Beiherhund das Oder die Flipperwaldt gersput!
@@MFKR696 And you don't conflate dry humour with lacking personality.
4:40 TACTICAL DOG DEPLOYMENT
Although i love the cnc project, its nice to see the latest and greatest from Mao’s poundland
"my tweezer strategy"
I love that you added that sound effect when it exits the editing mode
21:20 - 22:30 For those who haven't noticed the hidden message in morse code, it's: HIIVITDTDETSEASVTTLTSTTI
The moment when learning Morse code finally pays off :)
I emailed these guys and they stated that they are working on a true TS-200 that use USB PD instead of Quick Charge. With that we may get far higher power going through usb c.
The TS80 was called TS200 in the prototype stage.
Francisco Mendoza Balderas yes, I know. I emailed them last month. The TS-80 uses quick charge, not USB PD.
Sweet.
dang it i just bought the ts-80 like two months ago.
Christian Hunt They refused to give an ETA for it, and stated they needed more time to work on it. I would be surprised if it came out this year, especially after working on this power supply.
Wow, this does look very slick. So, you over-boost, capacitor smooth, smooth with ferrites, then use an RC filter with a series pass transistor? Did not see a monster diode, so it must be fully synchronous. Looks like it has some huge multi-layer ceramics. They make 107s now. Lots of brainpower went into this design! Seems like the feedback loop time would suffer -- but I guess the whole thing is so high frequency that it does not. Must be running at >1MHz. Glad you took the time to "screwdive" right into it. Am putting that word into my collection of favorites.
TH-cam recommended me this and I have no clue what is going on, but I'm still watching.
Bitte mehr von solch langen Videos Repson!
Von wegen in der Kürze liegt die Würze; je länger, desto besser ;)
Ich liebe deine Videos, deinen Style und Humor!
Grandiose Entwicklung, die du über die letzten Jahre an den Tag gelegt hast.
Die Zahlen sprechen für sich, also gerne weiter so :)
Your quadrapedal drone is awesome, but I'm not in love with the deployment mechanism.
Some sort of STOVL system?
With a ramp?
And a little pop out wing pack on the silly little thing.
Oooh, and a remote sensor pack, width radar and flir.
I would recommend trebuchet for maximum deployment efficiency
That is some awesome equipment. Wish I was smart enough to test it like you. Great work on displaying its capabilities.
this is one of the most entertaining an informative Reps videos i've seen in a while... and it's half an hour! aren't we lucky
(keep up the CNC stuff, tho, it's super interesting)
Too bad that they again didn't implement USB-PD. Though admittedly the QC 3.0 is a lot easier to do, USB-PD can do up to 100W, which would be really useful with this as well as their TS-80 soldering iron.
The ts80 is still great in my opinion, mine has been working great after i flashed a new firmware to it
I'd rather have the DC barrel jack than USB-PD.
@@ionstorm66 The power supply has the barrel jack as well and for the soldering iron you have the TS-100 if you prefer the barrel jack.
@@sasodoma exactly. PD is only useful for power banks, most of which won't do 100w.
@@ionstorm66 Or for users of high end laptops with PD chargers, no me though. Barrel jack from old laptop all the way
That looks a lot like a turbomolecular pump, for getting rid of those last pesky air molecules. You spray, set traps, and once you have air molecules, and what is worse, too few for Brownian motion, you got to fling them out one by one.
Excellent video with honest intelligent reasoning and analysis. Keep up the great work!
18:05 "shudden sort shircuit"? Okay Connery, settle down.
limejet 😂 reddit.com/r/shubreddit
Shurely shome mishtake?
Deine Vidz sind echt der Hammer! Kann man sich immer wieder anschauen, wirklich sehr geil!!
Very interesting gear. Sometimes efficiency is relative. I was playing with an old Philbrick +/-300V tube based linear power supply, and they touted efficiency in their data sheet. There was no switching pre-regulator in those days. I don’t recall how many watts the filaments consumed.
I love those flat wire inductors they sometimes use. I recently got some from coilcraft for a project of mine pretty much because they look cool (and have excellent DC resistance).
Ancient evil of the wind turbine?! Simply awesome. I dunno WTF you're talking about half the time, but you touched a brother's heart, subbed
2:11 He's actually missing an eyebrow. Ladies and gents Marco has officially passed into the realm of mad scientist/engineer.
xd cant you see the "little edit"
I have their electronic load. It's very nice. Battery powered, has sense wires and dissapates a ton of power and actively cools it.
You legitimately freaked me out and startled the hell out of me when I saw that tentacle come out
I've used those exact Erem tweezers for years, they're glorious.
You almost killed me with that one eyebrow, hazy in the background.
Tweezers? that is clearly cable ties..
He better put back those rubber feet, or it can short-circuit
@@preslavenev5351 O noo.... the case is always conected to live.. that is standard
Don't forget to wear the wrist band mate!
@@alidollar1994 Fight thermal paste cancer
Just use the thermal paste applicator tool.
I love every video from you
Keep up the good work ^^
You can set the input limit current. Just long press the menu button on the power supply and it the first option and set current lower, so won't draw 4 amp on a power bank.
I really appreciate the detailed testing. I have seen a couple other folks on youtube "review" that same power supply unit, but nothing close to this. Of course, this is not surprising at all because your content is almost always top-notch - but again, I really do appreciate it. Makes me wish that I actually had a need for that thing!
Oh yes! another Marco vid. All is well with the world
i love your soft German voice. Would you consider voice acting for audio books, im sure you would do a killer rendition of my favorite book: Der kleine Vampir. it would be mush appreciated.
That would be quite a drastic change in careers. Though I still second the request :D
Great investigation and explaining operation.
i love these videos.
took me ages to find itnagain.
I'd forgot the channel name,
Well worth finding again
And he did not add the information about the distance measuring device.
These Videos are Pure Art .
Wow, Impressive powersupply!!
Thanks for sharing :-)
Fascinating and entertaining as always
This is a nice bit of kit... might go get me one of these...
Pretty nice stuff there, dude. 😃
Beautiful little dog!!!
I have no idea what you're talking about mostly because I'm not an electrical engineer but you are one funny guy and entertaining enough to get me interested in what you're talking about ....you would make a great Bond villain. You actually remind me of my high school physics teacher who used humor to make physics entertaining and interesting and physics and was my best class. Thank you.
Love this guys sense of humour😂
He is putting lots of effort on it
That "long ferrite" definitely moved when you touched it with the probes!
21:57 Good catch! First place I would look if this thing quit working. All it would take is a light drop and it would pop those cold joints right off.
You do best reviews ever!)
Nice video... Very informative... Thanks for the disassembly and metering tour..!! :)
So much wowee sauce, so little time...
I can't believe my good fortune at having discovered this channel.
Excellent video !
Oh no, he has a turbopump, run for your lives !!
Uber vacuum incoming!
Hints to remove the noise in switching power supplies. There are several FETs for the switches, which can have the noise significantly reduced by adding an "asymmetrical, bi-directional RC filter" (resistor in parallel with another (resistor & series diode) ) in series with the gate. This alone can reduce the noise by an order of magnitude. To get to uV noise levels, measure the noise frequencies with a spectrum analyzer at various loads. Amazingly, most will be in the 50 to 200 MHz range. Use a de-tuned parallel resonant inductor filter (~ 0.5 uH || 5 pF || 4.7 kOhm for starting values)) in series with the output, ~ -40 dB in the FM band. Calculate and simulate all you want, but the values will have to be optimized empirically.
Fun Facts: 1) Even though the switching frequency of the power supply is dozens to hundreds of kHz, it is the rise and fall of the switches (and rectifier diodes) which generate the noise in the above (and higher) bands. 2) Rectifier diodes, when starting to conduct, generate a high current pulses in these bands regardless of switching frequency. 3) Because of the VHF (and higher) frequencies involved, you can add all the capacitors and inductors on the output and still have a lot of noise.
a shudden sort shircuit lmao, you're a genius
Thank you genius! Great explanation.
Amazing review
I hope that micro-epsilon works out for you; we had a devil of a time getting it to work. It seems it doesn't like green soldermask, and we were using it to characterize board flex.
I like the look of those Minidoodah thingys, I know that it's not quite the same through TH-cam but they feel like good quality to me, without seeing them in person.
Please, never stop :)
I love you man. These vids rock
Just started watching. Waiting for you to use the Chisel as a screwdriver.
BTW: how long does it take for an eyebrow to grow back?
depends on how it has been removed: if shaved off half a year maybe, if plucked out with cool tweezers, a lot longer I'm afraid
@@reps might make for another great and awesome video though. just saying
Eyebrows ? Half will be back in a week or two.
Source: I have to do it all the time.
@@reps When is that tattoo gun being put to use? I'm sure you could mount it to your CNC...
@@namAehT still got it ... just working on the laser to remove failed attempts
Until Marco said it, I didn't realize I needed a "tweezer strategy" but now I do.
i can understand only 10% of whats going on in this channel. Good enough for me - SUBSCRIBED!
$199 to $250 for the MDP-XP plus shipping. Sainsmart is the US seller via Amazon.
I made a power supply like that (smps+linear in series) in the 80's.
I have no idea what your talking about but I still love your content
Oh my that axial vacuum pump is getting me hype
Thanks for the deep dive. I ordered the successor that is a bit higher and has more max power (MDP-P906) yesterday and wanted to see if the price is justified. It seems. Still relevant to this day.
great humor, as always
Love the dota reference
You should put that laser distance sensor above a turntable and make a vinyl player that never wears out records.
Oh no, your organs will turn to jelly after visiting those wind powered death machines.
My man Marco still riding my grandpa's bike
recording the infrasound of the wid turbine is super cool tbh
Loved the tear down. Have you looked into firmware updates? I bricked mine somehow attempting it.
oh my... 2:12 the single eyebrow... you absolute mad man!
I love your vids so much
If Don Quixhote has taught us anything, it is "Do not taunt the windmills!" Also, do not taunt the Happy Fun Ball.
If Super Happy Fun Ball starts to smoke run and seek cover.
Very well done video! I've seen this unit before, but I'm holding for few other items on my shopping list, like Rigol DP831 - do you have any suggestions, rather than buying the Rigol? Also, I have the same screwdriver you have - love it very much! Anyway, thank you for the video again!
@Marco Reps May I ask how much is the estimated cost of the displacement sensor? :) I just found this sensor from your video and saw that this might be helpful to my colleagues working on artificial muscles/soft robots (quantifying performance).
Wow your toys are amazing, I just dribble over the tech.
The width and depth of your knowledge is top class.
Does the electric screwdriver have a torque clutch, has it got internal gearing.
Dexter the quadruped lab assistant needs to make more appearances
Love Miniware...
Another superb video. Damn you. Hehehe. So take this: "shudden sort Shircuit"
You have to hand it to them, they actually build useful stuff.
It may not be able cover every odd job but for the average Joe it is more than sufficient.
@Marco Reps is the noise at 11:20 from Dota 2? it sounds like the noise when you try to attack an invulnerable building (ie, racks before you kill the tier 3)
cute dog! nice video. thanks for sharing
I've had a minor obsession with trying to detect very-low-frequency sound (infrasound and below) for a couple of years now. Unfortunately, it's been hampered by my thoroughly corroded brain and my spotty-at-best knowledge of electronics. But your laser experiment gave me an idea: picking up sound with some sort of absolute position indicator. A high-resolution linear encoder, perhaps, or a rotary encoder attached to the vibrating object with a piece of steel wire on a pulley.
Now I just have to learn to read resistor color bands, remember the names of the terminals on transistors, and, most importantly, get off my lazy arse and actually solder something once in a while. But when I get there, infrasound.
COME ON MARCO U CAN DO IT
I hope someone puts most of the integrated circuits in that thing to a single ASIC!
When are you going to start making videos again!? Your content is top notch.
WOW just WOW LOL I love your stuff
i would pay for just sitting in your tech room!
Did it break after one eyebrow?
Why did the long ferrite move? Something broken? Maybe desoldered due to heat?
I love your videos You inspired me to start a youtube channel and follow my passion about electronics and robotics I hope someday to be one of my subscribers You are awesome
the windmill sounds like 90s arcade game music
What is that sound effect at 10:00? Mip map. I would like to have my notifications sound like that
It's from dota 2
meep merp :D
Big fan of the DotA references :^)
Never used a height gauge like that before! LOL.
50€ wtf? YES deploying the rocket dog just made my day =D
Wow, that is a beautiful power supply. It would be so much better if the output is isolated.
also much better if less expensive:(
1:20 - AAAAAaaaaaaaaa! What a fright! 😁
Basket launched semi-autonomous four-legged companion
... and it looks great.
A sudden "sort shircuit" 🤣
I wanna use that laser distance thing as a completely overkill automatic bed leveling sensor on my 3d printer. You could do like real time mesh adjustment with that thing probably. Maybe that's already a thing and I'm stupid.
