Game of Life on a Flip-Dot Display

With the passing of John Conway, I decided to add ‘Game of Life’ to a Flip-Dot project I’m working on, in honour of his work. I show a couple of random starts, a start from text ‘Hello!’ and a start with some known forms. Physical display is an Alfa-Zeta XY5 28×14. I’m building it into […]

Pi-Hole and Smokeping using Same lighttpd Service

I was having random – or not so random – internet dropouts on a 4G WiFi router. I wanted to ascertain when they occur and if it’s internal wireless or WAN to troubleshoot. smokeping is an old but useful tool to capture this as it sits in the background constantly pinging pre-defined servers. Since I […]

Whitterm-220 2.0

Having used my clever serial terminal – the WT-220 – for a few years now, I’d identified improvements I wanted to make. I was never that pleased with the cobbled together electronics (based on what I had laying around and ability at the time) and with PCB fabrication accessible to hobbyists now thanks to China, […]

Wooden Bits Binary Clock FPGA Port

In attempt to get started with FPGAs and Verilog, I decided to port Wooden Bits to a Lattice IceStick – selected because of the Open-Source IceStorm toolchain. Counters and flip-flops are the first thing one learns when starting with FPGA design, so the project lends itself naturally. I learnt things FPGAs are good at and […]

Samsung Frame TV Oak Tripod Stand

Being part of a generation that doesn’t watch TV…except documentaries and films…and YouTube…as well, might as well watch it on a big screen. Got a TV, a Samsung Frame – designed to look like a picture frame. It can mount flush to a wall or be mounted on an easel inspired stand, which Samsung sell separately […]

Is Bristol Choking – Air Pollution Web App

I had some of my Nixie Pipe displays showing air pollution data collected by the council, using a Python web scraper at an art trail and people seemed very interested and unaware of the data. I considered how good it would be to have live displays at the air monitoring sites for people to see, […]

Adventures with Flippy the Flip-dot Display

Considering my next project, I wanted to make an electromechanical display using magnets. I turned to the internet for inspiration and quickly came across Flip-dot displays; solenoid driven pixels. A good starting point for what I wanted to do, I looked further. I found a 900mm, 56×7 display on eBay from a bus salvager (who […]

Nixie Pipe – Modern Day LED Nixie Tube

Nixie Pipe is my interpretation of a modern day Nixie Tube – the cold-cathode vacuum gas-filled tubes from the 1960s. The project came about when I decided to make a clock for my kitchen, with specific requirement for an egg timer function! I’ve always wanted to make a Nixie Tube clock but having completed a […]

Raspberry Pi Data Logger with InfluxDB and Grafana

A need popped up at work for a data logger for various lab tasks. Quickly looking at the market, I failed to identify a lab tool for data logging (cheap, easy but powerful setup, remote access); something for researchers and scientists. I decided a Raspberry Pi with some input buffering would be ideal for the […]
