Now, you can test all those
BASIC Stamp modules you have
on your bench, ensuring they are
reliable and up to the task of
driving your next project. NV
Building the Tester On a Budget
So, you want to build one of these little gems, but don’t want to pay for
three mini-boards ... understandable. The average hobbyist only needs one
anyway, right? Before I started at Parallax, I had already built my own test board
based on a discussion in the Parallax support/discussion forums.
Figure A is my home-brew version which later became the board discussed
here. All of the parts were obtained from my local RadioShack, including the
solder ring board itself.
Figure B is a shot of the tester being used on a Board of Education. Using
the card version means if you don’t build the module tester, you can still test
24-pin Stamp modules on a BOE.
