  • Rack Mount TLRN goes to Germany

    After a successful installation at both OggCamp 2013 and FACT’s Cloudmaker: Making Minecraft Real exhibition, TLRN — the three wire hanging crane is next to be installed as part of the Public Engineering project that links Bochum and Liverpool. When Ellesmere port won the Vauxhall/Opel contract to build new Astras,...

  • Maker Faire 14 ­- Enchanted Toys

    A much more stripped back stall for DoES Liverpool for this years event. As there seems to a bit of an Internet of Things (IoT) speciality at DoES, the table showed a selection of devices that interact with the internet in some way. Alongside a newly re-designed WhereDial and the...

  • Building Doodlebots

    Doodlebots are simple to construct drawing robots that create random coloured patterns as they vibrate around on a sheet of paper. I’ve run a couple of workshops on making doodlebots and even a workshop on running and preparing for doodlebot courses. It’s a really great activity; the doodlebots are simple...

  • Cheertree

    I’ve previously had a “5 minute project” at Christmas time, where I made laser cut Christmas trees. The files are up on thingiverse so you can cut your own. This year’s is a more extravagant LED Christmas tree where the colour can be set by anyone via twitter. Finished, in...

  • Intro to Laser Cutting — New dates

    There are another three dates for the Introduction to Laser Cutting course: Saturday 7th December 2013 Saturday 18th January 2014 Saturday 15th February 2014 I had 4 people for the first course who all went away very happy with the new items, knowledge and skill that they’d learned. Only £69.55...

  • TLRN — A Wire-Supported Hanging Delta Robot

    Here’s a little teaser of a current project that I’ve been working on. TLRN at OGGCamp If you take a delta robot and replace the parallel linkages with the a pair of parallel wires wound over motor pulleys then you get a robot that can scale up to giant size....

  • Shrimp-on-a-shield

    I’ve been describing Arduinos as a “gateway microcontroller” a lot while introducing them to new users. They’re great to get started with, you build your first project include your first Arduino board in it, and then you have to go out and buy another one. And then you’re hooked on...

  • CoffeeBot monitoring with Arduino

    So, after I described using an instrumentation amplifier to take strain gauge readings using an Arduino, what was all that theory for? To measure the amount of coffee in the DoES Liverpool coffee pot from the next room over of course. A “Coffee Bot” if you like! Reading the contents...

  • Intro to Laser Cutting Course, September 2013

    As part of my role as DoES Liverpool’s technician, I get to give introductions to new users to get them started with using DoES’s laser cutter. However, because it’s only an introduction I only get to spend an hour or so going over the basics when I’d like to spend...

  • Reading Strain Gauge Scales with Arduino

    One of the smaller projects that I took to Maker Faire last month was a strain gauge reading circuit for Arduino. While the Arduino in the demo setup was actually redundant (the voltage input from the scales was output to a 5V dial gauge directly) there was also a circuit...
