A proper cyberdeck should look like it was kludged together in an alley in the Sprawl, under a sky the color of a television tuned to a dead channel. It should look like you can close it up, run through a crowd, jump onto a subway, and disappear into the night. It should look like anyone can make it, but only you can use it. Mike Horne’s little Raspberry Pi Cyberdeck checks all those boxes. Here’s more from Raspberry Pi Pod:
A 3S LiPo gives approx 11.1V, which is obviously too much for the Pi which wants 5-5.2V. I grabbed hold of an adjustable buck converter that takes a high power feed and converts it (steps it down) to whatever voltage you need, courtesy of a small adjustment pot at the top. Here it is with the pot turned to approximately what I needed. I later adjusted it to 5.1V to give the Pi some headroom.
You’ll see that the output of the converter goes into an Enviro+ board that is plugged into the Raspberry Pi Zero 2 W. This is where things get a little convenient. I knew I wanted some kind of sensor display for the project, and I happened to have an Enviro+ already. With a little experimentation, I found that I could take the voltage out of the converter and “shove” it into the GND and 5V pins of the Enviro+ and this would power the Pi. Marvellous. There is a cheaper board – the plain Enviro – so you might want to consider that. I also realised that I could add a control button to the Enviro+ by soldering a button to the other GND and #4 (GPIO 4), so I did that as well. The nice thing about the Enviro is that it breaks out “just enough” pins to make it easy to add things on. Those I2C (SDA/SCL) pins are just begging for more sensors – I don’t have any more room in the case, though!
