relaxing kit build: multi-voltage power supply

[@captcraig777]

The power supply kit looks way better than that beer. I bought an adjustable power supply, but I also bought this today for some smaller applications. Thank you for showing your process in putting this together!

[@paulbush7095]

An eye surgeon would be proud of your manual dexterity dealing with those pad mount components.

[@ronostrenski8359]

Nicely done. I’ve been building kits for 50 years and even though I’m a retired electronics tech, I continue to build kits to keep my soldering skills up to date. This must be one of the nicest kits ever with a nice range of component types. Also works very well.

[@matambale]

Always enjoy a kit build, and I think your buddy might just have been pranking you on that....'beer'....

[@GnuReligion]

Enjoyed seeing you dunk the solder wick into melted resin. Never seen someone else do that. Sometimes I cut a piece off, and fluff it up a little before saturating it.

[@johncoops6897]

I always smear the rosin paste flux onto the wick with my fingers. That is really yukky, but worse... the flux then transfers to my soldering iron handle, which is currently covered with a lumpy black mess about 2mm thick. Disgusting! I need to change my habit on that!

[@GnuReligion]

@@johncoops6897 Well, you can always lick your fingers clean. Lead dust gives it flavor. My workplace is scarred with melt burns.

[@Choober65]

HOLY SH*T, I thought my bench was a mess. Obviously a sign of genius 😁

[@Johadart]

Welcome back Kent, hope your rest break was good for you, great video to start off with, awesome job mate, keep up the great work bud 🤙🏼🇦🇺

[@markusallport1276]

What a great job Kent. I love these little kits, a lot of fun for beginners, and a chuckles for guys like you and I cause it keeps us sharp on tactics! I totally enjoy these videos and please keep them coming.

[@jerril42]

Thanks Kent. That was a nice surprise. I’m visiting family in the US, so it was nice to have a Canadian broadcast for Canada day. Enjoy the weekend and have a real beer 🍻 Cheers

I have been watching your videos for some time now. I finally got the courage to try my first kit, I chose the Kim Uno. Maybe not the best choice. The 24 small switches were a pain to do. My prior soldering experience was just large through-hole components like capacitors and testers for repairs. I struggled at first until I realized my soldering station came with lead free solder. Once I switched to 60/40 tin/lead things went much better. To my surprise and delight, it worked the first time! I now have this ordered PL2303TA USB to TTL RS232 COM UART Module Serial Cable Adapter for Arduino so I can start doing more with it. I have also ordered a couple more kits to build. Eventually I want to build the Z80 MBC that I have the board and most of the parts for. Many thanks for showing me the way. Also I have a soldering fume extractor on the way. Not liking smelling the fumes.

[@Ni5ei]

Peanutbutter & jelly beer? OMFG the things they come up with to get in the picture! What's next, macaroni & cheese beer???

[@wrxs1781]

Because of my bad luck and trepidation with surface mount components I now use conductive adhesive, my soldering skill is not as proficient as yours. The ceramic tipped tweezers will be my next purchase, good tip.

[@booboyBL]

Good job! I built this exact same kit a couple or so years ago, purely for the fun of it. I find soldering (and watching others solder) to be very relaxing and therapeutic. BTW, you did a better job than I did, but I was still quite new to soldering at the time. it's not so relaxing however if the job is something that actually needs to be done RIGHT and to work. (I'm thinking desoldering/resoldering the kernel rom chip on my C64 to upgrade it)

[@DustinWatts]

Nice build! Great supply for OpAmps and other things that need dual power rails. However, for audio stuff I would recommend using adjustable regulators and an half wave rectified AC power source. Far less noise when it comes to audio.

[@englishrupe01]

Great kit build, thanks, Kent. I have one of these i built that is used in conjunction with a signal generator board....pretty cool, thanks.

[@G_Fresh_UK]

Nice to see you do a 3d print case for it..

[@englishrupe01]

Yes, i have the kit too and have often wished there was a case for it....unfortunately i don't have a 3D printer.

[@jj74qformerlyjailbreak3]

I ordered these kits ehen you posted this video. The first kit was missing xl6008e1 chip. It took up untill now for me to get the replacement. Seems great for vreadbord projects. Maybe a diy trainer kit

[@RocRizzo]

Thanks. Now I know that I am not the only person who has a bit of trouble soldering surface mount devices.

[@wardprocter2371]

Happy Canada Day! This kit build did not disappoint, except that now I want one and they’re currently unavailable. 🙁 I’m pretty crappy at SMD stuff but this looks doable. I seem to recall a fellow Canadian KZbinr advising that “the bigger the gob, the better the job” so never worry about the amount of solder. I have to say that your circuit diagrams keep getting better and more understandable. Also, thank-you for the upside down inductor - maybe one more heat sink turned sideways just to completely trigger those that require order and symmetry at all times, lol. I really question the motives of a “friend” that would gift a beer like that, then again, I had someone who brought over a six of grapefruit radler a while ago so I guess there’s no accounting for some peoples tastes.

[@onecircuit-as]

Great build - to the shops! 👍😀

[@DevelopWithDan]

Very cool kit build. I could see that being handy for some of my retro stuff. Those things always needed multiple voltages, including negatives for the ram and expansion cards. Btw, that desoldering gun is pretty great with fixing bridges on the smd stuff. I fixed some on those really tight clpd chips.

[@pileofstuff]

Hadn't thought of trying the desoldering gun on SMD. Thanks for the suggestion

[@RocRizzo]

Thanks!

[@amydamon2323]

Ali Express says this is no longer available and I have not been able to locate it anywhere else. Too bad, it looked like a very handy power supply. Thanks for the video. I enjoy watching your kit builds very much.

[@pileofstuff]

Oh no! Edit: It appears to be back in stock!

[@englishrupe01]

Just search with "5-24V to +12V,-12V +5V -5V +3.3V DIY Power Supply Module" and you will find plenty.

[@johnbandhauer9224]

I built this same kit some time back. Mine works fine when powered with 5 volts; all the output voltages are good. But, with an input of 9 or 12 volts, only the 5 volt output is correct while the other outputs are low and the leds blink. I never bothered to figure out why. I don't recall testing with any load on the outputs other than a meter to see if that made a difference. I have used it without problem a few times when i needed multi voltages. I just wrote a note on the back to remind myself to only use a 5 volt input and got on with life. Still, an oddity that I bet is a problem with mine and not typical.

[@qwaqwa1960]

For the inductors: Put solder on both PCB pads & both inductor leads first. Then, easy to melt on...

[@qwaqwa1960]

Ditto for the regs...if your iron has enuf oomph (oomf?)

[@SidneyCritic]

I have bought cheep LEDs where some had the flat on the wrong side - lol -.

[@pileofstuff]

I usually test when I'm dealing with random cheap Chinese LEDs - a guy can never be too sure.

[@johncoops6897]

I've got a collection of LEDs where the flat is wrong and the longer lead is is negative.

[@FUNKLABOR_DL1LEP]

nice work! but to get maximum cooling effekt of the big solderpads underneath the regulators, they should flat soldered onto them. so I would take some flux and smd soldering paste, but it between and heat it with hot air or by the soldering Iron. 👍 and the soldering of the inductors wouldget much better, if you used flux and tinned the pads before placing the components. try! kind regards, Jens

[@TheEmbeddedHobbyist]

If you have a usb lead plugged in and a second for programming from your PC you will be bypassing the barrel jack switch. Never a good idea to switch the 0V (ground) as you never know if two things with the same ground ref can be connected either side of the switch.

[@pileofstuff]

Agreed. I thought it was an odd choice as well.

[@dmrsibs27]

Thank you for the video.One question though I built a similar board about a year ago and I installed the heatsinks at the back of the regulators not on top of them like you did.Will that affect their efficiency in heat transfer?

[@pileofstuff]

Probably a little, but unless you are running the regulators near their maximum current load it may not matter too much.

[@frankowalker4662]

Nice kit, easy(ish) build, and it works ! What could be better ?! (other than having a NICE drink to go with it. LOL)

[@noggin73]

Very nice! Those voltage regulators would have liked a bit of flux, but it worked so who cares.

[@TheEmbeddedHobbyist]

thiner solder and a smaller tip is all you require for those large SMD's.

[@johncoops6897]

Or learn how to "wipe solder" using any size solder and any large bit.

[@michaelwolak3098]

Hi where did you get this kit from Michael

[@pileofstuff]

AliExpress. There's a link in the description.

[@cncdavenz]

Hi, I did build this kit and it let the magic smoke out. Congratulations on your build. Did the beer get tipped down the drain or did you give it to the dog 😂

[@pileofstuff]

I finished it. It wasn't easy, but it's a sacrifice I am willing to make.

[@markclark787]

I use a clothespin for things liken the regulators

[@johncoops6897]

That wont be very reliable. Much better to solder them.

[@bwselectronic]

I would not think of peanut butter and jelly being sour. Probably would be better if it wasn't sour.

[@shroomy7199]

Good kit nice build. It wouldn’t be you if you didn’t get something around the wrong way

[@1963knight]

flux?
