Your own electronics lab... in a tray!

- In this video I want to show you how you can set up your own electronics lab in a tray! It has adjustable power supplies, a PICkit3 programming adapter, a volt and ampmeter, and even a little logic probe. And the best part: it doesn't take up a lot of space, you can get everything for around $150, and if you don't need it anymore you can just tuck it away under your desk!
Thanks for watching, and let me know in the comments if you have any questions!

My son and I are setting up a lab and will be doing a lot of work with chips - this is the best video by far that has informed my choices on what to get, thank you!
That's wonderful to hear, Victor, glad I could help! If you have any questions, feel free to reach out, I am happy to help :)
I've watched a few videos on this subject. Most of them ended up showing labs that would cost well over $1000 (more like >$2500). It doesn't have to cost that much just to start. I did not know about those USB power supplies, they look very handy. Thanks for another great video Jens, take care.
Thank you, I am glad you like it. These supplies can be very handy, but they don't provide a lot of power, so it probably makes more sense to get a switch mode power supply when you are getting more serious. For a few LEDs here and there these work great, though :)
I'm totally beginning in electronics and reached your channel while looking for 555 circuits and loved the video about it. This channel is definitely gold
Thank you, Bruno, that's great! Thank you for your kind words, it means a lot :)
Same here! and yes, this channel is amazing!
Thanks for the USB power supply info.
Your quality content give us another level of satisfaction. Keep making this please
Thank you so much for your kind words, much appreciated! The next video is almost done and will hopefully be out in a week. Have a great day!
@@FriendlyWire We will be waiting!
Really helpful
Awesome, glad it's helpful! :)
Another GREAT VIDEO! 😎
Thank you so much, Alan, it means a lot! :)
I watched few of your videos. They are awesome. Nice work 💖
Thank you so much, Sanath, much appreciated! Happy new year! :)
Awesome , your tutorials are awesome :)
Thank you so much, Sebastian, that really means a lot! Have a great day! :)
@@FriendlyWire Sir please update more electronics/microcontroller tutorials videos , your tutorials are simple to understand :)
@@sebastianthomas8507 Glad you like them! They take me a long time to make, but I enjoy it very much and there will be more in the future :)
Really great idea with the tray. I'd like to be able to set my project aside at times, but not have to pack everything up.
Glad you like it! Yes, especially if there is only one desk available this type of solution can make your life simpler :)
3:18 Warning. These cheap low quality adapters usually have counterfeit/fake components. I've had two of these fail. One of them fried a new PCB I was working on for weeks, due to an overvoltage from a voltage regulator that suddenly decided to die.
Good to know, and thanks for sharing! I had good luck with the ones I used; one of them has been powering my binary clock for 2 years now with no issues at all.
@@FriendlyWireThey are very convenient, and work very well until one day they don't, and then end up frying your precious electronics projects. Replacing the voltage regulators with known genuine components might be an idea, but that's not really ideal for beginners (which I assumed was the target audience for this type of video).
@@SeanChYTI have never heard of this problem before, interesting. Of course they have a maximum current, did you run them in spec?
@@FriendlyWireYes, it was hardly any current running when it happened. I guess one doesn't really know what you're going to get when you buy things like these. The chips can be ok, they can be DOA, or they can be marginal. I bought three units at once, and probably all the three boards got the voltage regulator chips from the same supplier and possibly also from the same production batch. I could just have been unlucky. I have stopped buying ICs completely from sites like AliExpress, after getting too many fakes, noname, rebranded and broken chips from there. When checking one of the voltage regulators afterwards I saw that it had a dead short between the input and output voltage pins. Buying from Mouser and Digi-Key may be a little more expensive, but for my own projects I don't risk it any longer, and I haven't had a single issue with anything sourced from those places.
Hey regarding Pic mcu, can we encrypt the source code such others can't exploit the code??
Yes, there are ways that you can turn on code protection in the configuration word of your PIC controller, and that prevents the code from being read out externally, but I have never used it so I am not an expert.
Do you store assembled boards from all your videos?
Yes, most of them are stored in little bags. The smaller tutorial ones are taken apart, but I keep the wires and components in little bags as well, just in case :)
Or pay for a snap programmer, is new cheaper and powerful, the down side is that only supports the new pics
Interesting, do you have a link to that programmer?
@@FriendlyWire i love pics microcontrollers as you can see haha
