I'm the guy who donated the Sony GPS! I've since discovered that it's the electrolytics on the display board that fail, resulting in "Dead Screen Syndrome" & not a loose flat-flex.
The postcard took me by surprise, since I've lived up in the mountains in NV looking over Tahoe for 4 years so far and I see those mountains every day :P
I remember when that first came out. I wanted one to toy around with, but it was too expensive for that. I could be wrong, but I think it was closer to 2K. The link here says 4 parallel channels, but I seem to remember the first device had to cycle though a channel at a time to get a fixed position... taking some time to achieve that.
10-79 would be the manufacture month and year. Ꜿ is a dotted lunate reverse Sigma, or a dotted lunate Antisigma, or Antisigma Periestigmenon, which comes from the Hellenistic period of Ancient Greece. The only use I could find for the symbol was for editing. I can't find any uses of it in maths, sciences, manufacturing, etc.; not that finding that kind of information is easy especially when its used on parts from decades ago. Edit: Or at least the backwards C with the dot looks like an Antisigma Periestigmenon. Could be something completely different.
www.rw6ase.narod.ru/00/rp_p/kwarc404.html It's made for Moscow olimpic game 1980. There are many electronic marked with this word in that period. But radio called Кварц(Kvatz).
I'm sure that might help, but It may still thermal throttle the CPU when it gets to hot regardless of the operating system. I have the 4Gb ram/64Gb model and it works really well, but needs a heatsink on the back of it to keep the CPU cool.
+Jacob Adamsky It's the latter. Windows 10 is only a little better than Vista. Truth be told, I'm a Penguin. Windows 8.1 was good enough for me to avoid Linux withdraw when I had to go a bit without dual booting, but 10 is only good on my W10 Insignia tablet. On my laptop, I only use the Windows partition for games and school software that's not Linux compatible. And that stuff is going to be put on Linux as soon as I can.
Yeah, I have the 4GB RAM/64GB LattePanda. I've found that you need to use a 3A power supply for it to run stable. I've also had to add a low profile heatsink to the back for it to run cooler. Other than those quirks I've been pretty satisfied with it. Btw, the LattePanda team has made a power-on-plugin BIOS that you can flash so that the board powers up when you apply power to it.
"Hello, LattePanda customer support. Is it plugged in? Have you pressed the 'on' button?" ;-) Sony GPS and HP power supply - beautiful. It looks like the Panasonic Toughbook didn't survive wartime service.
The little windows computer around 13 mins. Windows is VERY disk heavy and low quality SSD's don't usually buffer writes very well. I've seen bad herky jerky performance with Win10 on low end SSD or SD card storage. The windows kernel scheduler is terrible with high I/O wait times. Put linux on it and it'll run very fast.
Doesn't necessary have to be, I have a cheap windows tablet with very simmilar specs (32emmc/2gb, slightly weaker atom even) and when it comes to boot times and light tasks like web browsing, movie watching, etc. it feels very simmilar to my desktop, wich i would considder as current high end. Actually with both the 8.1 and then 10 update the tablet has become smoother in operation, there seems to be some kind of "burn in time" though untill everything runs as desired. But you are still right, some Linux distros will probaply be faster
Designandrew My information comes from being an I.T. professional that has studied the I/O issue with the windows kernel. I've compared, and timed things on the same hardware purpose built for the testing with cheap non-buffered early SSD's and a low end SD card. It's not an emotional issue for me, just an interest.
34:40 - those power supplies are designed for the system to have a bunch of hot swappable fans that suck air through the front of the sever case and out of the back. So all the air flow would have to pass over the power supply.
At 2:50 you can see the "Moskva 1980" text below the tuning dial. As pointed out by someone else it means "Moscow". If you notice the image to the left it is the logo for the 1980 Moscow Olympics. At 14:00 the sluggishness might be due to Windows checking for, and downloading, updates in the background. As to having to use a button to power on you should check if you can get in to the BIOS of the unit. If it is using a standard type of BIOS there will be an option that says whether the unit should power back up after a power loss or stay off. At 34:30 the power supply looks like one that would be used in a rack. The rack would provide the cooling so there would be no need for any active cooling within the supply itself.
13:35 The cursor bug seems to be a Windows 10 thing. I've had several sufficiently powerful systems occasionally do that for a short time after booting.
Damn I'm watching mailbags from 5 years ago. These videos hold their value pretty good don't they? Thanks from the states, I took basic electronics design and programming in the Navy (96-2000) Long ago but I can follow along with most of the circuit explanations, I missed alot changing my field so TH-cam has filled the gap in a very satisfying way. Thanks again!!!
Hi, About the Soviet calcuator and radio, some people have already explained, what MOCKBA means and what was Estonia in 1980s (so they could actually be manufactured in the Estonian Soviet Republic - but I have no idea whether they were producing any electronics there). But I can explain what says on the calculator rear side. Factory number: (I can't read it) Date of manufacture: 0280 (I presume it means February 1980, and it makes sense, taking into account the components day codes) 3 x 1.5 V; Price: 55 rubles BZ-14 (not B3-14!); Manufactured in USSR Only watching it for the third time I understood the "Australian model" of the cell :-) The radio can receive long waves (ДВ - DV - LW) and medium waves (СВ - SV - SW) and the scale is, of course, in terms of the wavelength in meters instead of frequency. On the radio rear side, there is a range switch, and on the label it says: Radio receiver Kvartz 404 Olympic And in the small boxes: APP-IV GOST 5651-76 (it seems it's a standard it complies with) Powered with 9 V 2 ranges: LW - MW Price 32 rubles, 20 kopeks
Amazingly I _had_ heard of the lattepanda before seeing this. I was trying to find a good media center alternative to my raspberry pi, but I don't know if it supports HDMI-CEC, that alone has kept me with the pi over all the competition. 16:11 If you could figure out if it supports HDMI control that would be helpful to me because I could probably ditch windows 10 for OSMC and seriously improve my media center game.
I wanna know if the spray can ingredients are all the same. yes? no? Plus the presence of a ball bearing indicates there are solids present in the can that settle when sitting.
The audio player from Creative that came before the iPod was called the DAP Jukebox, or something like that. It came with up to a 4GB hard drive, and then there were instructions on the net about how to upgrade it with a 20GB 2.5" laptop hard drive in order to get more storage out of it.
Come on Dave... at least spray something (ANYTHING!) with the nano-stuff and dip it in some water. Surfaces treated to be hyrdophobic (which is basically what is described in the blurb) are VERY obvious once you give them a dip in the ol' H2O. All the other products that I have seen which do the same thing are a 2 part treatment (and expensive), so a 1 part system would be very interesting. So please.... spray and dunk!
I saw an experiment back in the 80s where a guy sprayed a 240V lamp holder and lamp with CRC/WD40 and dropped it in a bucket of water. That seemed to work.
HP power Suplies do have fans in the blade server 1U and 2U redundant systems that do run fans on the server side to cool the power supplies. They do have an independent card that monitors the hardware with its own network port to report when one fails back to a central monitor server. I've taken one apart before when doing server engineering, they are packed tight but do stay cool in a properly cooled and ventilated data centers.
Being an owner of a baytrail based (about 10 to 20% slower than cherry trail socs) 8 inch tablet with windows, I can assure you all this choppines is windows 10 doing updates and installing stuff. One thing I immediatly noticed was the sound/volume icon showing a big white X on it, so the sound driver was still being installed and initialised. I'm 100% sure that the little beastie will run fine after all the updates are done.
emmc stands for error memory module correction if the print is correct its the same kind of memory in servers i.e. no memory loss and/or data error correction
The GPS signal was changed in the 1990s and this receiver needs a new chip to work. I know because I have one. Sony did not offer a new chip to make it work so, it is useless.
@@richardneidhardt1828 You have the correct year, but GPS didn't change. The issue is actually caused by the GPS week number rollover. Certain GPS units, including the Pyxis, cannot handle the week number rolling from 1024 back to zero. It would have worked after the week number had incremented enough (the exact count depends on the receiver), but it again rolled over in 2019. The GPS signal has been added to, but never in a way that breaks compatibility with older receivers. Even my Magellan Trailblazer will still work, aside from the bug mentioned above. (I'm not sure if mine is affected or not, I need to check.)
Hey, I still use an old school MP3 player - several in fact, several iPods and Toshiba Gigabeat. Because why not? 160GB capacity dedicated 100% to music. Rockbox firmware could be loaded on many models and players everything from 24-bit FLAC to C64 SID music files, and MIDI files when provided a GM SF2 bank. Beat that!
The date on that calculator will be the four-digit number on the back of it. It also has the price (шена, 'shiena') of 35 rubles on it. In that radio, the date code is on the back of the tuning capacitor; it's a Roman numeral for the month and two-digit year.
IF leakage out the antenna is a common failure mode, mostly likely caused by front-end transistor zapped to short from gate-to-drain. Radio will usually still work, albeit at reduced sensitivity.
Can you scan and post the manual for the Sony GPS? I've got one, but I don't have the manual (just finished repairing it... same bad caps on the PSU daughterboard)
high voltage electric motor used to spray on that and see if it still works after going deeply into water for a couple days. or get a cheap cell phone and trying the spary on it and dunk it in water for a couple days and see if it works after?
Since rack servers are typically packed with fans (think at least a row of fans all across the width of the chassis) I think the pressure difference would force enough air through that psu to cool it.
That LattePanda looks like it would be a great project for a custom car computer hidden away behind a touchscreen monitor that fits in the double-din opening, replacing the factory radio altogether.
Its probably is based on standard PC build. I'd think you would be able to select always on in the BIOS (or wake on lan etc..). If I had designed it, I would route the power on signal to the header for external use (if required) & install the PBT for prototyping. And it needs a power button because its a windoze PC, you will need to hold the power button down for 10 seconds at least once every 6 months.
micro usb jack is handy but always soldered semi-thick wires directly to my Raspberry servers PCB to ensure wiggle-safe and low impedance PSU connection (had some stability issues with not-so-good USB cables)
the psu is active cooling - the fans are in the system, usually 2 rows of fans all across (2 rows for redundancy).they can get quite loud under load but they move a lot of air.
@34.00 Servers are built like wind tunnels, blasting massive CFM's through the case to keep the hardware within spec. If you wanted to be in a server room, bring ear plugs! The noise can reach into the upper 90-110 DB range. The upper range especially if the servers are working at nearly 100% load.
The server power supply would have a bank of high flow fans behind it. I've seen servers like that in the past, most times they would have three hot swap power supplies in the back.
RE: The Proliant Server Power Supply. There are no fans in the actual power supply as the server has many fans arranged so that a very high volume of air passed from front to back. So pushed through the PSU. I work in a Data Center, and standing behind a rack of servers is like standing in front of a bunch of hair dryers. They certainly kick out some heat.
I love those Creative Zen mp3 players, always gave good battery life and sound quality. I had a hard-drive based one, now I'm using a newer flash memory one for audiobooks, use it for about an hour a day and it only needs charging every 3 weeks or so :)
Server power supplies rely on the server case drawing air through them, thats why it looks passive but problably aint. most servers wont even boot without the internal fans behind the power supplies fitted.
2:00 comical sound bytes file. Dave have you thought about saying not to send time sensitive packages as you cant guarantee that you can get to it in time.
"Creative Zen back in the day" Back in the day, never considered myself old. Aside from the size and heft, it was one of the best gadget pieces I've ever owned. Next time I see my parents I'll have to dig it up to see if it still works!
As far as that server PSU goes, it's passive as a module, and hot swap-able as you've indicated as well as the circuitry monitors the supply and unit performance while reports health stat's (to what was traditionally called a BMC (Baseboard Management Controller)) but have been redefined as of late. To address the passive appearance, the server unit to which this PSU belongs is doing the forced air with hot-swap fans (of course they are!) and it's quite typical of these systems to pull in ~68*F ambient air and kick out ~100*F exhaust. Quite well constructed and reliable these power units are. Being in the industry for over 9 years (since 2007) and working in a rather large data-center with thousands of servers and having multiple PSU's each I've only replaced a handful (
The power supply is from a very old ProLiant DL360 G3 and provides 325 Watts. Nowadays you can get 1.200 Watts in about the third of the volume, that's almost 12 times more energy per volume. And also those are 94% efficiency with much less heat generation !
If you would have used the USB power adapter for bench power supplies out of the recent mailbag, the small PC most likely would have also worked from your bench power supply.
I've had to replace a few of those HP power supplies. There's a light on the back and the front of the PC plus the ILO reports back via email when they fail.
You may have seen this, a while ago AvE used an unprepared drill to drill underwater. Cordless drills are not really a challenge as they work reasonably well underwater anyways.
I had a Creative Labs Zen Touch - made the commute downtown to work on the train tolerable. I still have it, but the hard drive crapped out. Battery life was actually pretty good for the time - I could get 2 or 3 days of commuting with it.
I believe I have the same USB cable You can plug it either way, but some of them are faulty and will drop a lot voltage during load when plug one way, not the other.
1) CPU of the lattepanda is on the BACK SIDE. 2) i run boinc on it and it's very very hot. if you dont give it a proper heat sink or a fan, it will throttle to ~0.3 GHz. 3) lattepanda seems very sensitive to power voltage. you'd either need a cable with very low resistance or a power supply with output slightly higher than 5V (like 5.2V-5.5 V) to compensate the voltage loss by the cable.
Edge is a brand new browser MS did from zero (supposedly) for Windows 10 and it's usually the best option for those single board computers and cheap stuff with Windows 10, since Chrome will love to gobble up to 1GB+ of RAM for a single open tab, since it opens one separate instance for every extension you have, as well as every plugin you have.
+Pyrofan97 I don't think so, apparently it's a fork of the trident engine that was used in internet explorer - en.m.wikipedia.org/wiki/Microsoft_Edge#Features
1GB with only one tab?!? I suppose you have 30+ extensions. I just keep Adblock, and it's reasonably memory efficient (unlike, for instance, firefox, which has become a pain in the ass).
funcatvids Not really. Only uBlock and Disconnect. Keep in mind that Chrome opens: -1 instance per plugin you have (Flash, Java, etc.) - 1 instace per extension you have. - 1 instance per tab you have open - 1 instance per element that requires hardware acceleration By default, when you open vanilla Chrome, it already starts with ~8 instances and using about 400 MB of RAM just idling. Put a TH-cam video on that tab and the RAM goes up to 1 GB. I have Firefox open right now, three tabs open with 4 extensions and it's using only 1 GB.
That HP PSU is from a 1U DL360 server (looks an older like 10 years ago one) - they have a load of small high speed (and loud) fans elsewhere in the chassis which forces a surprising amount of air through the PSUs. I've used one of these when I needed a decent amperage PSU before (20+ amps) and strapped a small fan to the end forcing air through it - they do overheat easily though.
Back in the mid-90s (as far back as I really go) there were GPS receivers with as few as 6 channels - just enough to hold 4 satellites and keep a look out for a couple others to switch to if the ones you're tracking are obstructed. A nicer one would be 8 channels.
I'm the guy who donated the Sony GPS! I've since discovered that it's the electrolytics on the display board that fail, resulting in "Dead Screen Syndrome" & not a loose flat-flex.
Just found retro-gps.info/Sony/Sony-Pyxis-IPS-360/index.html and wanted to say the same.
I seem to remember seeing a scanned ad somewhere that said $1,200 USD.
The postcard took me by surprise, since I've lived up in the mountains in NV looking over Tahoe for 4 years so far and I see those mountains every day :P
+Johnny Joannou Regretfully, I couldn't find a postcard for the pony express station in Fernley...Oh well!
I remember when that first came out. I wanted one to toy around with, but it was too expensive for that. I could be wrong, but I think it was closer to 2K. The link here says 4 parallel channels, but I seem to remember the first device had to cycle though a channel at a time to get a fixed position... taking some time to achieve that.
The transistor is a germanium PNP designed for low frequency amplification.

The markings on the radio actually say Moscow in russian
Made in Moscow?
No, he means the "mockba" is "Moscow" written in Cyrillic. Its pronounced "Moskva" in case you are curious.
No it has the logo of the Moscow Olympics in 1980.

what a classic radio, love it to much
Hey, I still use an old school MP3 player - several in fact, several iPods and Toshiba Gigabeat. Because why not? 160GB capacity dedicated 100% to music. Rockbox firmware could be loaded on many models and players everything from 24-bit FLAC to C64 SID music files, and MIDI files when provided a GM SF2 bank. Beat that!
The date on that calculator will be the four-digit number on the back of it. It also has the price (шена, 'shiena') of 35 rubles on it. In that radio, the date code is on the back of the tuning capacitor; it's a Roman numeral for the month and two-digit year.
Can the LattePanda run Linux?
IF leakage out the antenna is a common failure mode, mostly likely caused by front-end transistor zapped to short from gate-to-drain. Radio will usually still work, albeit at reduced sensitivity.
Anytime a new Windows install goes directly to the desktop it makes me nervous. More often than not it indicates something sketchy with the licensing.
Holy CRAP. The version of the LattePanda that Dave has retails for $139 US!! Why on EARTH would you buy that at that price point?
Because it's for everything!
lots of nice stuff! i like the battery pack and the pi 3 enclosures. really nice engineering there.
Can you scan and post the manual for the Sony GPS? I've got one, but I don't have the manual (just finished repairing it... same bad caps on the PSU daughterboard)
high voltage electric motor used to spray on that and see if it still works after going deeply into water for a couple days. or get a cheap cell phone and trying the spary on it and dunk it in water for a couple days and see if it works after?
Since rack servers are typically packed with fans (think at least a row of fans all across the width of the chassis) I think the pressure difference would force enough air through that psu to cool it.
That LattePanda looks like it would be a great project for a custom car computer hidden away behind a touchscreen monitor that fits in the double-din opening, replacing the factory radio altogether.
Think you could get Linux on the Latte Panda, or is that too much hassle ? Cheers
Power button...... WTF? That is just plain stupid
Its probably is based on standard PC build.
I'd think you would be able to select always on in the BIOS (or wake on lan etc..).
If I had designed it, I would route the power on signal to the header for external use (if required) & install the PBT for prototyping.
And it needs a power button because its a windoze PC, you will need to hold the power button down for 10 seconds at least once every 6 months.
Like other person commented. there is another bios with "autoboot" option
That knife should be made mandatory for every youtube unboxing ever.
what is the best oscilloscope max of 3k dollar in the market
Most rack cases have air going through the entire case, so you'd get plenty of cooling on the PSU.
Correct That is a HP Proliant ML3xx series server PSU. PSU chassis has active airflow though redundant fans as well.
micro usb jack is handy but always soldered semi-thick wires directly to my Raspberry servers PCB to ensure wiggle-safe and low impedance PSU connection (had some stability issues with not-so-good USB cables)
The radio says "Moscow", apparently commemorating the 1980 olympics.
If it's Windows 10, it's busy sending every little detail about you and your life back to Microsoft. So, you know, be patient.
Writing a biography. :) Pardon me, compiling a biography.
You say that, but I bet you have a Facebook page which is a thousand times worse than Windows 10.
Dave, how's the ACL feeling?
Yes, the air is forced by the server Fans through the whole server, including the power supply. Front to back.
the psu is active cooling - the fans are in the system, usually 2 rows of fans all across (2 rows for redundancy).they can get quite loud under load but they move a lot of air.
@34.00 Servers are built like wind tunnels, blasting massive CFM's through the case to keep the hardware within spec. If you wanted to be in a server room, bring ear plugs! The noise can reach into the upper 90-110 DB range. The upper range especially if the servers are working at nearly 100% load.
the power supply is cooled by the air draw through the server. they have lots of fans in them that draw a lot of air.
The server power supply would have a bank of high flow fans behind it. I've seen servers like that in the past, most times they would have three hot swap power supplies in the back.
for the server psu there are fans in the the server pushing direcly in the power supplies.
RE: The Proliant Server Power Supply. There are no fans in the actual power supply as the server has many fans arranged so that a very high volume of air passed from front to back. So pushed through the PSU. I work in a Data Center, and standing behind a rack of servers is like standing in front of a bunch of hair dryers. They certainly kick out some heat.
I love those Creative Zen mp3 players, always gave good battery life and sound quality. I had a hard-drive based one, now I'm using a newer flash memory one for audiobooks, use it for about an hour a day and it only needs charging every 3 weeks or so :)
Dave it really works but just for one year!! You have to spray it again, there is plenty in the spray tin.
awesome items in this mailbag!
That HP power supply is out of (by the look) DL360 G5. The case is pressurized and the power supplies are part of the vents out.
27:12 - I'm sure there was a scheme to erase and re-program that EPROM 'in-place' :)
Great! Another 50 minutes mailbag video, my favorite!
Good work dave, keep it coming and stay cool ;)
Server power supplies rely on the server case drawing air through them, thats why it looks passive but problably aint. most servers wont even boot without the internal fans behind the power supplies fitted.
Aren't server power supplies produced in mass quantities normally associated with consumer goods?
2:00 comical sound bytes file.
Dave have you thought about saying not to send time sensitive packages as you cant guarantee that you can get to it in time.
You missed the antenna part of the GPS receiver :(
"Creative Zen back in the day" Back in the day, never considered myself old. Aside from the size and heft, it was one of the best gadget pieces I've ever owned. Next time I see my parents I'll have to dig it up to see if it still works!
As far as that server PSU goes, it's passive as a module, and hot swap-able as you've indicated as well as the circuitry monitors the supply and unit performance while reports health stat's (to what was traditionally called a BMC (Baseboard Management Controller)) but have been redefined as of late. To address the passive appearance, the server unit to which this PSU belongs is doing the forced air with hot-swap fans (of course they are!) and it's quite typical of these systems to pull in ~68*F ambient air and kick out ~100*F exhaust. Quite well constructed and reliable these power units are. Being in the industry for over 9 years (since 2007) and working in a rather large data-center with thousands of servers and having multiple PSU's each I've only replaced a handful (
The power supply is from a very old ProLiant DL360 G3 and provides 325 Watts. Nowadays you can get 1.200 Watts in about the third of the volume, that's almost 12 times more energy per volume. And also those are 94% efficiency with much less heat generation !
could you check the Folding@Home performance of the Lattepanda?
If you would have used the USB power adapter for bench power supplies out of the recent mailbag, the small PC most likely would have also worked from your bench power supply.
what was the mailbag nr where he got the altitude geo thingi
I've had to replace a few of those HP power supplies. There's a light on the back and the front of the PC plus the ILO reports back via email when they fail.
could you do a tear down on the tough book ?
Could you print a nice clear cover for the the old transistor radio? Those internals are just too damn pretty to hide away:)
What about the other nana products? Can you do a test on those to see if it's bs?
Dave should make a sick fuzz pedal out of the transistors in that radio.
Another Win 10 compatible SBC in the Raspberry Pi format is the Up Board. available in 2gb ram/32gb emmc and 4gb/64gb
You may have seen this, a while ago AvE used an unprepared drill to drill underwater.
Cordless drills are not really a challenge as they work reasonably well underwater anyways.
spray the nanoprotech on your finger then place your finger in the mains socket .....does it do what it says on the tin?
I had a Creative Labs Zen Touch - made the commute downtown to work on the train tolerable. I still have it, but the hard drive crapped out. Battery life was actually pretty good for the time - I could get 2 or 3 days of commuting with it.
I believe I have the same USB cable
You can plug it either way, but some of them are faulty and will drop a lot voltage during load when plug one way, not the other.
I suppose you could use your insulation tester to see if the nanoprotec does anything.
What does Boinc do?
1) CPU of the lattepanda is on the BACK SIDE. 2) i run boinc on it and it's very very hot. if you dont give it a proper heat sink or a fan, it will throttle to ~0.3 GHz. 3) lattepanda seems very sensitive to power voltage. you'd either need a cable with very low resistance or a power supply with output slightly higher than 5V (like 5.2V-5.5 V) to compensate the voltage loss by the cable.
Usually hp servers have a central fan pack that sucks air in the back and out the sides of the case.
Edge is a brand new browser MS did from zero (supposedly) for Windows 10 and it's usually the best option for those single board computers and cheap stuff with Windows 10, since Chrome will love to gobble up to 1GB+ of RAM for a single open tab, since it opens one separate instance for every extension you have, as well as every plugin you have.
They didnt do it from zero, edge is based on chromium.
+Pyrofan97 I don't think so, apparently it's a fork of the trident engine that was used in internet explorer - en.m.wikipedia.org/wiki/Microsoft_Edge#Features
1GB with only one tab?!? I suppose you have 30+ extensions. I just keep Adblock, and it's reasonably memory efficient (unlike, for instance, firefox, which has become a pain in the ass).
funcatvids Not really. Only uBlock and Disconnect. Keep in mind that Chrome opens:
-1 instance per plugin you have (Flash, Java, etc.)
- 1 instace per extension you have.
- 1 instance per tab you have open
- 1 instance per element that requires hardware acceleration
By default, when you open vanilla Chrome, it already starts with ~8 instances and using about 400 MB of RAM just idling. Put a TH-cam video on that tab and the RAM goes up to 1 GB. I have Firefox open right now, three tabs open with 4 extensions and it's using only 1 GB.
That HP PSU is from a 1U DL360 server (looks an older like 10 years ago one) - they have a load of small high speed (and loud) fans elsewhere in the chassis which forces a surprising amount of air through the PSUs. I've used one of these when I needed a decent amperage PSU before (20+ amps) and strapped a small fan to the end forcing air through it - they do overheat easily though.
46:00 THAT LOOKS COSMETICALLY STUNNING
That old transistor radio beats my own age for one year :P
The radios scale shows the wavelength in metres instead of frequency
5:20 I wanted one, but price bit high.
Wait... was the hard drive on the creative zen a Zif or IDE based connection? It almost looks like it has both somehow. XD
Back in the mid-90s (as far back as I really go) there were GPS receivers with as few as 6 channels - just enough to hold 4 satellites and keep a look out for a couple others to switch to if the ones you're tracking are obstructed. A nicer one would be 8 channels.
