Revision 2 resources are available from the download link as a TGZ file. More details and documentation will be posted after fixing a few issues with the current revision. Prototype boards shown in the image were ordered from OSHPark (1.11 x 1.56 inches,...
The first order of the day is to design a landscape irrigation controller and incorporate an integrated WiFi module. There are a number of WiFi topologies available, but the preferred is the Serial Peripheral Interface (SPI) connected modules. I prefer...
By having the system permanently embedded in your body, you have a different type of controlled environment which cannot be interfered with by the various day to day lives of people.The electronic components within the system are small but require a...
Each intelligent shield needs a micro controller to implement the intelligent shield protocol.The shield system uses the I2C bus, but adds dynamic address allocation. Therefore the will never be an address conflict between shields. The I2C bus is the...
The in-wall switch module has a custom PCB mounted inside a 3D printed shell, and includes a 120 VAC to 5 VDC switcher, a relay, and a Spark Core microcontroller with Wi-Fi. The prototype uses a mechanical switch for direct switching but the goal is...
Detailed Explanation:To begin with, I had to research how my truck unlocked the power doors. I thought it was a simple 12 V on a switch but I was definitely wrong. I found that it needed a “Negative Trigger” on a certain wire through a...
March 28, 2012The design I settled on is comprised of three barrel plugs and a single 3-lead audio plug (float sensor, pump pressure switch sensor, temperature sensor, and rain sensor), two solid state relay-controlled electrical outlets (pump and 24v...
Back in 2011 I was wanting to build a custom PCB for a Arcade Fight Stick. I could have easily ordered a Toodles Cthulhu Multi-Console PCB (or similar), hacked up an old wired Playstation controller, or purchased a commercial fight stick to satisfy my...
It's good to know a radiation level in your neighborhood, but carrying Geiger counter around is a little bit uncomfortable and can attract unwanted attention. ;) With this things in mind I decided to build my own Ethernet enabled Geiger counter. I used...

The box is composed of 3 parts:1) the top part, in grey, which holds the glass2) the middle part, which has been cut out to make a window for the lamps3) the bottom part, which has been cut out to make room for transformer and cablesI had to cut away...
First, Solder LEDs in line, measure the hole needed for the LEDs and Cut that out. Then Cut the Hole for the switch. Connect all the wires, because the powerline adapter is only 9v no further regulation is needed, fix everything with hotglue (except...
