This was my experiment in creating a low power Arduino that can communicate wirelessly to a Raspberry Pi using an HC-12. By low power I mean run for a couple of years on a 18650 battery. Encryption should be unhackable by today’s standards.

I did a …

I used to think that the default libraries in the Arduino IDE would be the best available but having come across a couple of cases where this isn’t true I would definitely search for better lib libraries now…

This is a small project to read wav files from a micro SD card via an Arduino Nano and then play them directly to a loudspeaker. I’ll state upfront that this isn’t the easiest way to do this (there are MP3 modules and libraries), but I wanted …

OK, so just for the record, I’ve tried using the NRF24L01 on the Raspberry Pi (via tha GPIO SPI pins) and I don’t recommend it.

So the following is just a record of what I did, in case I ever change my mind :).

This week’s project has been writing the software for my GPIO board on my Raspberry Pi. I added this board to a case I bought for my Raspberry Pi …

The first thing I did was installed Ubuntu on windows

Then I installed NodeJS and NPM (which I’m not sure if I needed).

And then installed Jekyll

To run it: jekyll serve --host=0.0.0.0

I edited .bashrc to add the GEM exports
