New York Timelapse

I’m much better at acquiring kit for projects than I am at building them, so I tend to have a lot of Raspberry Pis lying around. I’m very lucky to have access to a beautiful view of the New York skyline at the moment, so I thought one good use (partially inspired by the House […]

Web Controlled BeerBot

At the Singapore Hour of Code event I got a great tip from Melvin on how to set up a web control page for the BeerBot. In this post I’ll describe the first working version, which you can see in the video below (apologies for the robotic monotone on the voiceover).

Hour of Code

I spent Saturday and Sunday at Singapore’s Hour of Code demonstrating the BeerBot to kiddiwinks, parents and passers by. It was at Singapore Science Centre and was organised by the same team that runs the Singapore Mini Maker Faire. It was a lot of fun and I got some great ideas from some of my […]

Why No RPi Wifi ?

As mentioned in the last post the Raspberry Pi I have been using to control Squirty the RepRap suddenly decided to stop connecting to my home network. It would work with a different wifi dongle, but not with the one I have been using for the last year or so. The “broken” dongle was able […]

Two steps back

Building Squirty the RepRap has always seemed like a one step forward, two steps back kind of exercise. The last weeks have been a two step back phase.

Singapore Mini Maker Faire 2014

This weekend the Wife and I had a booth at Singapore Mini Maker Faire. This is the second year we have been and the first time that we had a booth. The Wife exhibited some of her oil paintings as well as some sewing creations. I showed the BeerBot and Squirty. Given the breadth of […]

Circuit progress?

After frying two DC/DC converters¬†last time round I had another go at putting together a power supply for the Raspberry Pi controlling my RepRap using an ADP2303 IC. The new circuit still can’t power the Pi, but at least it is now able to hold a 5V output voltage with a small load on it.

Please internet, fix my circuit

I have never had much success with analogue electronics. This weekend I wasted 6+ hrs trying to get a pretty simple circuit to work. Then I fried the parts so I can’t work with them any more, this at least is a blessing as it can no longer suck up time and generate additional frustration. […]

Beerbot Mark II

I’m very excited to have a stand at the Singapore Mini Maker Faire in July and I’ve been working to tidy up two projects to exhibit. One is a refurbished version of my Beerbot (last seen here). The aim behind Beerbot is to be able fetch a beer from anywhere in the house and bring […]


Working to ¬†connect a Raspberry Pi to a reprap made me think about resurrecting my BeerBot project. I worked on this in 2012. It is a robot made of a lego mindstorms kit with a raspberry pi sat on top of it. The pi acts as a mini web server broadcasting images from a webcam […]
