SoR Kit assembly, Part 1

December 5, 2009

If you have purchased the SORKIT1 here at CircuitGizmos, or even if you purchased the parts somewhere else, you might be interested in the Gizmo build of the circuit board controller. The Society of Robots instructions here have a handful of steps for building the $50 robot. Steps 3A, 3B, and 3C have to do [...]

Testing new U401/U421 function – Part 1

October 30, 2009

New capabilities are being added to the U401/U421 firmware. The first new function that I am testing here is a “Quiz Show” function. Also called “Fastest Finger First”, as it shows which line, of all sixteen of the lines on the device, has been pressed first. This capability is used in game/quiz shows and contests. [...]

Counting to 2F

October 4, 2009

I keep a lot of old things that I’ve made. Perhaps too many. In cleaning out boxes of old circuit boards – full designs, partial designs, experiments – I found a board that I had put to a lot of good use. Many times I’ll have a latched 8-bit port on a microcontroller that I [...]

Prototype PCB Design/Documentation

July 7, 2009

I use a lot of the protoboards like the one sold here at CircuitGizmos for developing prototypes of all sorts of circuits. Too often, though, the circuits are created but the effort isn’t documented. Often times the prototype is considered for reuse or modification later, but then it has to be reverse-engineered. With document templates [...]

Analog to Digital Converter Demo – Sensor Interfacing

March 10, 2009

Post on a (sometimes offline) blog at: http://robotics.reefat.com/2008/08/22/analog-to-digital-converter-demo-sensor-interfacing/ using the U401 and an ADC0804 for analog conversion. I’ll repost the pics and code here. Oddly, the video was removed because “Fox” considers it to be a copyright infringement. Um… ?? Someone needs to explain this to me… (Author doesn’t know why, either.)

U401 with 16 LEDs and RobotBASIC

February 1, 2009

This is a quick post showing a U401 (#CGU401) driving 16 LEDs. 12 of the LEDs are available here from CircuitGizmos. The square LEDs that are amber colored are just some extras that I had on hand.

U401 and Solderless Prototype Boards

January 20, 2009

If you use solderless prototype boards (solderless breadboards) for circuit testing, the USBmicro U401 (#CGU401) combined with a 30-pin header (#CGPINHEAD30) is a great way for you to connect a test circuit built on a solderless prototype board to your PC. The one-tenth inch on center pin spacing of the U401 lends itself well to [...]
