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.

E3D Titan Extruder – Minimum Motor Size?
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.

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

Previously I discussed my intentions to smart-ify my doorbell – I want to know if I’ve missed a delivery while I’m out, and this seemed like a good way to go about it.

Today I wanted to take something apart, and the people that made it clearly disagreed. The screws holding the thing – a doorbell chime – together were a type of security screw I hadn’t run into before.

In Part 1 I talked about the programming arrangement that I used for the first batch of Z probe boards. After flashing that batch of boards, I got to work on a slightly more automated solution.
