Launching a Custom Kerbal Panel

[Matthew Peverill] is a busy PhD student who loves to make time for a little Kerbal Space Program. He was tired of using such pedestrian controls as a keyboard and mouse for such important work, and wanted something a little more like they have down in Houston.

For this project, …read more

Blue Pill Makes Cheap But Powerful Morse Tutor

[W8BH] attended a talk by another ham, [W8TEE] that showed a microcontroller sending and receiving Morse code. He decided to build his own, and documented his results in an 8 part tutorial. He’s using the Blue Pill board and the resulting device sends code with paddles, sends canned text, provides …read more

CB Radio + Arduino = 6 Meter Ham Band

Somehow [hvde] wound up with a CB radio that does AM and SSB on the 11 meter band. The problem was that the radio isn’t legal where he lives. So he decided to change the radio over to work on the 6 meter band, instead.

We were a little surprised …read more

Dice Reader Brings Tech to Your Craps Game… Or, Ya Know, D&D

There are truisms about dice that you’ve probably already heard: if you have just one of them it’s called a “die”, opposite faces of each die always add up to seven, and those dots that you’re adding together are known as “pips”. But what about the infrared properties of those …read more

Ping-Pong Ball Makes Great PID Example

It is a common situation in electronics to have a control loop, that is some sort of feedback that drives the input to a system such as a motor or a heater based upon a sensor to measure something like position or temperature. You’ll have a set point — whatever …read more
