Every FPGA vendor describes their parts a little differently – Xilinx counts “logic cells,” Altera counts “logic elements,” Lattice counts LUTs – and there’s surprisingly no single place that lays the families side by side. So I built one. This is a cross-vendor reference to the current, in-production FPGA families

I recently moved into a new house, and wanted to put together a quick-and-easy garage workbench for DIY projects, home improvement tasks, and maybe some general woodworking.

I picked up an EMAX TinyHawk S micro quadcopter. I’ve had a quick play around with it, and I thought I’d share my thoughts – and a few small modifications I’ve made.

When E3D announced their new Titan 3D printer extruder with 3:1 gearing, I was immediately curious as to how small a motor I could get away with using.
Continue readingRUMBA+ vs RAMPS: A Thermal Analysis
I recently got my hands on a FLIR One thermal camera, and I’d been dying for the opportunity to put it to use. I also recently received the first batch of RUMBA+ boards for testing, and I realised this was the perfect opportunity to test both.

3D Printing and Virtual Reality are two of my favourite emerging technologies. Recently I had some fun combining them!
Continue reading3D Printer Error Detection (Part 2)
I’ve been working on an encoder-driven system for error correction for a few months now. I posted a video last month, and after a much-appreciated post by Hackaday there was quite a bit of interest – so this is a follow-up post about the project.
Continue reading3D Printer Error Detection (Part 1)
I’ve been playing around with magnetic encoders a lot lately in the hopes of getting some sort of error-detection system up and running. I think I’ve finally made some headway on it.
Continue readingIoT Doorbell Part 3 (OpenHAB and MQTT)
Last time I took apart my doorbell, added an ESP8266 and connected it so it could detect when the doorbell was ringing. But how should I communicate with the ESP8266, and what should I do with this data? I decided to explore the OpenHAB home automation software and came across
