57M-SS Hall effect button – Matt Venn
http://www.mattvenn.net/2015/06/18/57m-ss-hall-effect-button
Engineering, design, music. Portfolio & CV. 57M-SS Hall effect button. June 18, 2015. June 18, 2015. Series of switches by ITW switches is a nice button, but the datasheet is useless. As of June 2015). It doesn’t describe which pins do what or how the button works internally. It’s a hall effect (solid state) style switch with 3 terminals (plus 2 for LED on some models). The pinout is described in the picture below, with I being input, O being output and G being ground. Hope this helps someone! Realtime d...

Engineering, design, music. Portfolio & CV. December 12, 2014. January 1, 2015. I’ve always wanted to do something arty with my CNC router but never quite known what. After the simple drawing robot (originally inspired by the Art-o-matic v1) I thought I’d get back to basics and build a harmonograph – a set of pendulums Read More ….

Using a camera with Scratch on the Raspberry Pi – Matt Venn
http://www.mattvenn.net/2014/12/16/using-a-camera-with-scratch-on-the-raspberry-pi
Engineering, design, music. Portfolio & CV. Using a camera with Scratch on the Raspberry Pi. December 16, 2014. I needed camera control with Scratch on the Raspberry Pi for a primary school aerial photography project. I added a new python extension for Simon’s ScratchGPIO. That allows either the Raspberry Pi camera or a regular USB webcam to be used with Scratch. Follow Simon’s instructions for installing over on his site. If it’s a USB camera then just plug it in.

CNC spindle speed controller – Matt Venn
http://www.mattvenn.net/2014/12/01/cnc-spindle-speed-controller
Engineering, design, music. Portfolio & CV. CNC spindle speed controller. December 1, 2014. My spindle speed controller broke and it seemed a good opportunity to learn more about phase control of mains voltage, and closed loop feedback control. I found a great writeup of a very similar project by Klass. The controller consists of:. An RPM sensor (an opto emitter and receiver pair) mounted in the router body. A TRIAC to control the router speed. A zero cross detector so we can do phase control. Gridalicio...

ESP8266 investigation and an internet connected Galvanometer – Matt Venn
http://www.mattvenn.net/2015/08/01/esp8266-investigation-and-an-internet-connected-galvanometer
Engineering, design, music. Portfolio & CV. ESP8266 investigation and an internet connected Galvanometer. August 1, 2015. August 1, 2015. Is a very cheap ( 3 delivered in single quantities) WIFI chip that makes it easy to add internet connectivity to a microcontroller. I got excited when I found you can also flash your own firmware and do everything on the one chip. I first heard about it on hackaday. And since then it’s been used in tons of IOT projects. Love that push and shove routing! But they have d...

Reading a GEO Minim energy monitor with a webcam and Python – Matt Venn
http://www.mattvenn.net/2014/12/28/reading-a-geo-minim-energy-meter-with-a-webcam-and-python
Engineering, design, music. Portfolio & CV. Reading a GEO Minim energy monitor with a webcam and Python. December 28, 2014. December 28, 2014. Unfortunately the GEO Minim energy meter doesn’t allow you to easily fetch the data from meter with a computer. This is bad because it means we can’t easily log the data or do anything. Here’s the repo with more info on setup, install and tuning. I have it running in a loop on a Raspberry Pi and then posting the data to the internet and my energy wristband. About ...
