QRPMe, Rex Harper’s site for QRP (reduced-power) amateur radio kits, has a nifty little prototyping board that fits inside of a mint tin and could be used for other types of mint tin projects. The board (and a mint tin to house it) cost $12 postpaid.

While you’re on his site, check out some of his other offerings, including a mint tin filled with QRP prototyping parts (secomd image above), tuna tin QRP transmitters, and QRP parts vacuum-sealed inside of tuna cans.

    I just got one of his newest kits: THe QRPer’s Pocket PAL.

    This is an altoid kit:

    The Pocket PAL is a mint tin sized tester for all kinds of hamfest goodies that you can’t ordinarily test with a DVM. Several constant current and voltage sources can be used to test panel meters, LEDs, and many other current or voltage driven devices. An on-board oscillator can running at 14.31818 and a divide by 2 circuit can be used for testing oscilloscopes, receivers, frequency meters and other RF devices requiring an RF signal. A Picaxe microprocessor is also on-board and will be programmed to act as a frequency counter with Morse code audio output, and an audio frequency sweep generator for testing headphones, speakers, piezo elements etc. A crystal oscillator ties to the frequency counter circuit for measuring quartz crystals.

    I will report back once I build it.

      Hey Mikey,

      Definitely DO report back! If you wanted to do a little review, I could post it as an item here on the site. My email addy is on the rail to the right.
