Snowbot

Dan Hienzsch a holiday project to build a little Snowbot with an adjustable speed larson scanner for an eye:

Snowbot Ornament Project

When I started thinking of this project, I wanted to make something that included a bit of the basics and something more advanced. It had to be battery powered, and most importantly, I wanted to make sure it went against the grain of everything needing a microcontroller. Thus Snowbot was born.

SparkFun Rotary Encoder Breakout Board

img_20170211_233051

I designed this simple breakout board in KiCad to make it easier to put a rotary encoder on a breadboard.   The KiCad symbol and footprint for the SparkFun rotary encoder was created by mcous on GitHub.  I used an updated version with corrected pin numbering.

Bristlebot with LDRs Becomes Light-Following Bristlebot

Bristlebot with LDRs Becomes Light-Following Bristlebot

Bristlebots are great because no coding is required – they’re completely analog circuits that just go! But if you wanted them to go in a specific direction, how would you do that? Facelesstech has released their design for a light-following bristlebot that uses two LDRs to drive either side of the bristlebot (so you could turn it, somewhat – see video below for demo!). It’s pretty simple and pretty clever.

SKiDL: Script Your Circuits in Python

SKiDL: Script Your Circuits in Python

SKiDL is very, very cool. It’s a bit of Python code that outputs a circuit netlist for KiCAD. Why is this cool? If you design a PCB in KiCAD, you go through three steps: draw the schematic, assign footprints to the symbolic parts, and then place them. The netlist ties all of these phases together […]

Surface-Mount Edge Connectors

FacelessTech designed this small board to act as a surface-mount edge connector:

SMD edge connectors

So you want to joint two boards together, You decide to use through hole female and male 2.54 pitch headers. Normally you would use through hole than ether have a 90 degree headers or just bend them over. For years this is how I did it, I would have to make sure I made sure the holes were just the right distance from the edge of the board.

Friday Hack Chat: KiCad with Wayne Stambaugh

KiCad is the premiere open source electronics design automation suite. It’s used by professionals and amateurs alike to design circuits and layout out printed circuit boards. In recent years we’ve seen some incredible features added to KiCad like an improved 3D viewer and push-and-shove routing. This Friday at 10 am PST, join in a Hack…
