NOTE: THE POCKETPAL Handy Dandy Hamfest pocket tester has been updated a second time... Check the Kits by Function buttons on the HOME page and select Mint Tin kits to find the latest version...Pocket PAL ][+. Older versions are Pocket PAL (original) and Pocket PAL ][ (green pcb). THE LATEST version is the Pocket PAL ][+ and is a red pcb.
It is listed near the END of the sidebar as the FDIM 2023 Buildathon kit.
I have turned it into the POCKET PAL ][+ to add more testing functionality and we will be building this NEW version for the FDIM Buildathon!
Changes:
1 The fixed 14.318 oscillator can & divide by 2 square wave circuit can has been updated to a Pierce crystal oscillator circuit with 2 jumper selectable crystals. TWO HC-49US crystals come with the kit but they are installed into sockets so you can change them any time you like!
Added a simple test keyer output
Added option control pot
The documentation for the original Pocket PAL ][ version have titles starting with Pocket PAL II, whereas documents pretaining to the BUILDATHON will have a ][+ postfix.
The PocketPAL is a mint tin sized tester for all kinds of hamfest goodies that you cannot 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 can 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.
As of November 27,2017, the PocketPAL kit is now a version 2 kit, Pocket PAL II, with all the mods eliminated and with new printed circuit board and parts set.
