CNC Router 3 axis test
Today for the first time I attached all the motors to my CNC router. Here are a couple of time-lapsefilms of me tinkering with the system
CNC Electronics : Arduino Uno + GRBL
After some considerable delay since I first started with the idea of building myself a cnc router, I am now working on the electronics in earnest.
Arduino uno – making electronics easy
I was having some difficulty understanding what was going wrong with my circuit. This week i got some probes for my oscilloscope, and that at least helped me see that indeed when the servo turned the best, the control signal looked most like a square wave
Learning electronics
I am a man of many interests. I generally feel there is not enough time to do and learn all the things I would like.
Project: Tilting lap desk
For the last couple of years my wife and I have introduced a tradition of making our gifts for each other. This year that gift was what I am calling a ‘lap desk’ but I guess it just a freestanding mini desk that has a tilting top.

Makeshift desk
In our house, one thing was made very clear from before we even moved in. The garage is my territory, and the study is my wife’s.
Using SpecFlow for WebDriver user acceptance tests – Pros and Cons
Recently in my team we have introduced the use of SpecFlow to held create business driven tests. Specifically we’ve been refining the way we work with acceptance criteria for some time, and have been pushing towards the Given, When, Then format.
Giza 66 clone – 8 shot rubber band gun
I really enjoyed making my clone of the ogg craft modotchao rubber band gun, and decided to take a crack at another which caught my eye.This one is the giza 66, and it is a much simpler gun than the modotchao. It has a single moving part, but there is some complexity to the gun.
