Building a Motorized Macro Rail: Part 2
Picking up from where part 1 of the Motorized Macro Rail project left off: Design Modifications I’ve made few improvements to the prototype design for the “production” version, as outlined […]
Read moreWhen it all goes wrong – 3D Print Layer Shifts
Printing one of the last parts for my motorized macro rail last week I noticed that the print quality had suddenly taken a major step in the wrong direction. The […]
Read moreArduino IDE Serial Port Issues
Getting back to developing on Arduinos recently after a bit of a gap, I was immediately hit by problems uploading code onto my Arduino boards. Obviously this was very frustrating […]

The Prototype Taking a (semi) objective look at this site recently I realised that it’s ages since I built a project with an Arduino. That’s certainly not because I’ve built […]
Read moreBack to Basics: the Dog Bowl Beauty Dish
While I’m waiting for parts for the stepper motor-based design I’m working on, I thought I’d take a quick trip back to basics. My first DIY photography build was a […]
Read moreHow to Use Arduinos to Drive Stepper Motors
I have a few stepper motors that were either bought or salvaged with the intention of using them for project builds. Since I’ve finally got round to starting work on […]
