LEAP#411 Cordwood III Archway Trigger Mod
This is the third Boldport Club project in the Cordwood series, and I’ve gone off-road with a true 3D archway layout. One thing lead to another, and soon I had a completely pointless LED blinking machine spring-loaded LED trigger machanism.

LEAP#410 Rube-Goldberg LED Blinking Machine
Here’s a marriage of Homopolar motor and Joule thief that results in a truly impractical Rube-Goldberg mechanism for blinking an LED with a AAA battery. It may be inefficient, but I like it .. mainly because I haven’t seen any quite like this before!

LEAP#409 Boldport Bugs: The Conehead
Conocephalus is a genus of bush-crickets, known as coneheads. Now I have one beautifully rendered in a 3D kit from Boldport. It even has a pretty convincing FM-synthesised chirp that varies in response to lighting conditions.
Boldport projects never fail to inspire some new learning. In the case it introduced me to Pure Data - a nifty open source visual programming language for multimedia. I reproduced the Pure Data chirp model and added a few more controls to make it easier to play around with.

LEAP#407 AC-powered DPS3005 Bench Supply
The DPS3005 is one of a range of popular DC power supply modules; this one is designed for up to 32V/5A DC output. For this project, I am mounting the module in a project case, and adding a rectified step-down transformer so the unit is powered from mains AC.
