I designed an audio amplifier with a friend. There may have been an error with the output terminal labels that released the smoke from the speaker 😳 #pcb #electronics #arduino #amp #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #tech #technology #design #audio

I upgraded the ToolPass board to hold a 30A relay. I had to increase the board copper from 1oz to 2oz to take the additional power. #pcb #electronics #arduino #particle #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #makerspace #workshop #engineer #layout

Space for the battery on the back of my first watch, I used a coin cell here, but probably should have gone for a lithium-iron battery instead. #pcb #electronics #arduino #esp8266 #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #tech #technology

The back of my second watch. There's a lot more packed onto this board, with several more chips needed to drive the low power sharp screen. #pcb #electronics #arduino #atmega328p #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #tech #technology #design #soldering

The 14 Segment node received data over RF and could display 4 characters, driven by an HT16K33. #pcb #electronics #arduino #atmega328p #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #tech #technology #design #soldering #diy #microcontroller

The front and back of my first RF base station, I kept all my designs to 50mm x 50mm to keep the price low. #pcb #electronics #arduino #atmega328p #electricimp #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #tech #technology #design #soldering #microcontroller

The MBTA tracker, before we named ourselves Traintrackr. I used 128 LEDs on this board, the most the HT16K33 chip could drive. #pcb #electronics #arduino #esp8266 #pcbdesign #diyelectronics #iot #sensors #pcba #cad #eaglecad #tech #microcontroller #mbta #boston #traintrackr

Weather display board, with space for several LED displays. I used an SD card here to store the WiFi and weather API details, but have since moved to using the internal memory of the ESP8266. #pcb #electronics #arduino #esp8266 #pcbdesign #diyelectronics #hardware #engineering
My WiFi-RF base station, unpopulated. I'm not sure why I added an additional power jack, the USB port provides plenty of power. #pcb #electronics #arduino #esp8266 #pcbdesign #prototype #printedcircuitboard #hardware #engineering #makerspace #workshop #engineer #layout

This was my first transit PCB, and covered the northern part of the MBTA in Boston. This (and all the other boards I designed over the previous few years) was the start of Traintrackr. traintrackr.io traintrackr.co.uk #boston #makerspace #mbta #traintrackr
