Last time I had determined that the long ribbon cable was too long to fit into the box.  So, I ordered a GPIO header with longer pins for the sense hat and a smaller ribbon cable with a 40 pin connector on one end and a 26 pin header on the other to plug into the PermaProto board. In order to make more room for the board and the connector stack, I removed the three screw terminal connector where I had planned to connect the wires from the Fog machine remote.      Usin ...
I finished up my last blog post by installing the relay board on my PermaProto board.   Next, I needed to assemble the level shifter board.  I say assemble, but all that's required is to solder the single row headers to the board.     Here's what it looks like with the connectors added.     I went ahead and soldered the level shifter board on to the PermaProto.  If I were thinking ahead I wouldn't have placed it so close to the connector.  I would ...
As I went about thinking on how to assemble the circuitry together to make a presentable project, I wasn't too happy with the idea of using the extended pin header for attaching the sensor board.  However, I found that the GPIO connector on the Pi will happily take an old computer disk cable.  Luckily, I had one of these hanging around.    The only gotcha with this technique is that the connector rows end up swapped around if you connect the sensor board with the connecto ...
As I read through Charles Gantt's blogs on the Foginator 2000, I saw that he used an off the shelf relay board to switch the fogger on and off.  However, I didn't want to spend the money when I could just as easily create my own relay board.  So, I sketched up the following schematic.  The inputs on the left go to the Raspberry Pi board and the outputs at the top go to the fog machine's remote control. I pulled the following parts from Seeed Studio's Arduino Starter Kit to buil ...
While I'm waiting for some parts to arrive, I decided to build the amplifier board that was supplied with the parts kit.  Here's what came in the kit:   Step 1 of the build was to install the resistor:   Step 2 was to install the diode:   Step 3 was to install the slider switch:   Step 4 was to install the ceramic capacitors:   Step 5 was to install the speaker and power connectors:   Step 6 was to install the audio connector:   Step 7 ...
