Originally, according to Wikipedia and other articles I’ve read wooden kitchen breadboards were used for electronics, which is where the term started. I’ve started using them too. I had a couple of accidents where they magic smoke was released from a couple of Arduino boards when an Arduino module was bumped and moved over a... Continue Reading →
Using the DS3231 Real Time Clock alarm with the Adafruit RTClib library
I love the DS3231 RTC module and have used it in a couple of projects without a library using code based on Ralph Bacon’s example. It worked well, but I wanted to use the alarm and working out how to do that was a step too far for me. There doesn’t seem to be a... Continue Reading →
A deceptively simple but not very secure security key
I recently recalled an interesting security key for a building car park at a block of units we stayed at a few years ago. It was a small block of units with maybe 10 - 20 units in the whole complex, probably built in the 1970s. Underneath was a carpark with a roller door to... Continue Reading →
Original Zork source code available
One of the first computer games I played was Zork. It was back in 1981 and on a Dec 20 mainframe. I have a lot of happy memories of Zork so I was interested when Hackaday posted that MIT has released the original source code on Github. It wasn’t the puzzles that interested me back...

Measuring audio frequency with an Arduino
When I was working on the Morse Code Decoder project I got unexpected results from the output of of the KY-037 audio module. The output was being monitored by an interrupt in the Arduino Nano. It was triggering far more than I expected. I wondered if it was triggering at the frequency of the audio... Continue Reading →
Morse Code Decoder using an Arduino Nano
Decoding recreated Morse code from the Titanic I find the history of Morse code fascinating. I admire those that are able to send and interpret Morse code messages at high speed. Some time ago I saw a YouTube video about a Morse Code decoder that was based on a micro controller. I didn’t see the... Continue Reading →
Hello world
Hi, welcome to my new blog. I created it so that I can share some of the projects and activities I do, not because they are great, but to entertain and inspire. I hope you get something from it.
