    Easy and Cheap Lab Regulator for Any PSU

    Great idea here, thanks for writing up this nice Instructable. I made a few changes in my version. First I used a different regulator board. Mainly I chose the one at this link because it is about half the cost of the one you specified. Also, this unit will handle much more current than the one you specified, and although I plan to limit the current draw to around 5A, this unit will handle up to 12A and has the heatsinks to handle sustained high current draw for long periods of time.I also used an "off-the-shelf" Radio Shack project box since I don't have access to a 3D printer and with so many stores closing, the sale prices at the Shack are too good to ignore.The last change I made was to use a Banana jack/binding post for the input as well as the output to give me a bit mor...

    Laptop Control Box

    Thanks for your prompt response, Carl! I was thinking that the change would be exactly as you stated. I've got it loaded up and everything is working just fine.I've got a couple of cool ideas for a different style of enclosure. I won't spoil the surprise, but I'll be sure to post some pictures when I have it finished.Thanks again and thanks for the great Instructable!Bill S. (Quantz)

    Carl, I am having trouble getting your code to work. I built the circuit, installed Processing and cannot get the Arduino and my Mac to communicate. I definitely have the correct serial port selected in Processing as it's the same one that I used in the Arduino IDE. Now I admit I am new to Arduino, but the <test_code.ino> file I downloaded and the <Laptop_buddy_rgb.ino> look identical to me. Shouldn't they be different? Please let me know. Thanks!

    the BOOKSHELF

    Clever design, but I have to agree with GeeB6. Spend a few extra bucks for a decent grade of plywood and skip the OSB. Your health will thank you!

    Hi again! I managed to locate the library I needed. Sorry for the bother. I'm enjoying working on your project and will be sure to let you know how it turns out in the end.

    Hi Mr. Kreindler, I'm having trouble locating a library for the DS3231 that will work with your code. Would you be able to point me in the right direction? Thanks, in advance, for your help!
