Digital Alarm Clocks

Three custom digital alarm clocks. Each slightly different. Each with many features such as dual crescendo alarms, dimmable display and battery backup of the time and settings. Read More


Parallax has an interesting kit called the M-Sorter. It really sorts M&M candies, and even Skittles. The device is incredible and ingenious in it’s simplicity and design, in that the whole project runs with only 1 moving part! In fact, the only devices needed to make this project work are the TAOS TCS230 Color Sensor (Available from Parallax with the kit), and a standard hobby servo (included in the kit). Read More

Custom Serial LCD Backpack

posted in: Other Projects | 0

When I first got into BASIC Stamps I was also introduced to the increasingly popular serial LCD since typical microcontrollers would lose too many pins controlling a parallel display. The Scott Edwards displays were the first recommendation and set me back $100.00, which was as much as I paid for the entire microcontroller kit I got to start. Read More

Build A Better Mousetrap

They say, “necessity is the mother of all invention”. Well, if that’s true then this project is living proof! Mice beware of the Mouse Motel! This BASIC Stamp 2 powered mousetrap can catch rodents live and alert you when one has been caught! You can then safely relocate the furry little rodents. This design could also be adapted to catch bigger animals as well. Read More

Prototype Alarm System

I purchased my first BASIC Stamp 2 Starter Kit in 2000. Once I got used to the programming I decided to port one of my existing alarm control systems over to it. This unit was the first alarm system I designed around the BASIC Stamp 2 to replace earlier Z80-based designs. Since it’s a prototype, it’s not intended for long-term use and differs slightly in design from the finished project. Read More


The BASIC Stamp Microcontroller can reduce the development time of many applications and therefore is a popular platform for both beginners and experienced developers. However the cost of the BASIC Stamp Microcontroller can be cost prohibitive in volume applications. This article shows several circuits and configurations for the BASIC Stamp 2 microcontroller designed to reduce BOM cost in OEM applications. These reference designs can be applied to all BASIC Stamp Microcontroller models. Read More

Prototype Audio Controller Main Board

Sometimes when you etch your own PCBs using resist ink you can have issues such as over or under etching the board. But I hadn’t expected that my failure to clean and seal the board properly after soldering would result in oxidation eating the board away over the course of a year until my most complex hand-etched board would fail, taking my favorite and most used / enjoyed project with it.
