Controlling 2 LEDs with 1 pin

Not many people know that it is possible to control 2 LEDs individually with just a single digital output pin. See the video below for proof. These 2 LEDs are both connected to the same pin, digital pin D5 on a Wemos D1 mini. How is this magic possible? Take a look at the circuit…

BBC Master 128 Restoration

Over the Christmas period, Mike was lucky enough to be gifted a BBC Master 128 along with a 5.25″ disc drive, a load of cables and a few games on tape. The poor BBC Master had been sat in a garage for approximately 10 years with a load of wood on top of it, gathering…

Magnetic Encoder Tests

I recently purchased some magnetic encoders to use in an upcoming project and hooked them up to a Wemos D1 Mini to try and do some basic testing. The specific magnetic encoder is the AS5048. Three wires were soldered to the PWM output pins only as this is a lot easier than soldering wires to…

Upgrading to a Pi 4 with SSD

Mike has decided to upgrade his InfluxDb and Grafana server from the Pi 3B+ to a new Pi 4 with 4Gb of RAM. To speed things up even further, he purchased an M2 NVMe SSD card to boot the OS from and make the speedy Pi 4 even faster. The SSD is a WD Blue…

ESP8266 Sensor Node

Mike has recently been adding some more sensors to his sensor network around the house. To add to the Weather Station sensors that are out in the garden, plus the Environmental Monitoring Station sensors and CO2 sensor node, a BME280 temperature and humidity sensor node has been added to the network. Data from this sensor…

Making an Arduino based Simon Game

So we decided at |Medway Makers to do a little collaborative project and to do a workshop on building and coding a ‘Simon’ game. This was mainly born out of a complaint from Tom that he had bought a mini Simon Game and that it was not the same game he remembered as a kid….

Meetup and Neopixel Workshop – Sunday 28th July

Our next meetup is Sunday 28th July. I shall be running a small workshop on how to use Neopixels and how to write code to control them using the Arduino or Raspberry Pi. We are a group of creative technologists that meet every 2-3 weeks on a Sunday between 11am and 5pm for a general…

Terrarium Fusion

We had a very interesting meetup on Sunday 27th January. For a change, we did something different and instead of electronics, for the first half of the session we built some terrariums. Tom turned up with a beautiful green recycled glass bottle he had just won on eBay as well as boxes and buckets of…
