Altoids Tin Electronics Lab (open)

Newer Older

This is a small electronics lab in an altoids tin. It contains nearly everything to work on small projects, such as a breadboard, components (including several ICs), and a adjustable power supply. The power supply is a simple LM317 circuit, with the 317's metal tab cut off to make it fit.

    This is one of those "D'uh" moments.

    While ANYONE could have thought of doing this, Nick Ames actually did so. A perfectly on target maker project.

    Thank you for sharing this!

    could you give a layout of the power supply?

    @place name here: It's a simple LM317 based circuit. There's a good tutorial here: www.ladyada.net/library/equipt/diypsupp.html. I used a slightly different schematic (I can't find the specific one) and my supply doesn't have the diodes or the 10uf capacitor.

    Hi, I'm an admin for a group called Fan>TAB>ulous Aluminum & Tin Can ART, and we'd love to have this added to the group!

    @Nick Ames: I have a few questions.

    1. Is the battery/battery pack underneath the breadboard? I can't see the battery anywhere for the power supply.

    2. Where did you get the trays for the components? I was just wondering because I kinda want to make it look a lot like your design to make it easier.

  7. Nick Ames 49 months ago | reply

    @twopastrs: The battery isn't included in the case; there wasn't enough room.
    The trays are made of folded paper, and are a small version of what I use to organize my main component supply. Take a look at the photo after this one for a closer view.

    Its wonderful!!!

    Where can I get resistors? I want to make jewelry. Other than pulling apart old electronics and scrounging them, when may I purchase them?

  9. Nick Ames 49 months ago | reply

    @urbanwoodswalker: You can get resistors anywhere electronic components are sold. If you don't mind paying too much money, you can get them at radioshack. If you want a better deal, there are a number of online retailers that sell components, such as jameco.com, mouser.com, and digikey.com. Personally, I've purchased from jameco and mouser with good results.
