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 [...]
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 [...]
Perceptive Radio Build Pics
I'm sure you've seen the write up from Mudlark and the blog post from BBC R&D; about their new Perceptive Radio that localises content and adjusts playback characteristics depending on listener [...]
Laser-Cut Elastic-Clipped Comb-Joints
During a makerday, I saw a someone struggling to put together a Raspberry Pi box that they'd laser cut, and were trying to hold together: two pieces of acrylic to [...]
Second Lattice Hinge Samples
As part of my first week as the new Technician-in-Residence at DoES Liverpool I've found time to photograph the acrylic test samples. From the earlier posts, this second set of samples [...]
Laser Cut Christmas Trees
I had half an hour at the end of the day at the DoES Liverpool makerspace the other day, so I had time to cut out christmas tree decoration from card [...]
Lattice Hinge Design — Choosing Torsional Stress
The first set of lattice hinge tests I generated were a little fragile, with the maximum stress in the torsional links set to be 60MPa (the yield stress of the acrylic) [...]
Lattice Hinge Design — Minimum Bend Radius
The last set of hinge tests that I showed used a cut out a rectangle of material to form the links. By re-arranging a formula that calculates the required inter-link clearance, [...]
Completed Laser Cut Brackets
You might remember from the other week that I had designed and cut some perspex brackets as an mounting for a piece of art for an exhibition. The show is now [...]
Go Technical Innovation
The 24 Heures du Mans (Le Mans 24 Hours) traditionally has a garage reserved for a vehicle that doesn't fit the current rules. Though the car runs unclassified and [...]
Git Workflow for Self-Updating Sites
Because manual integration and merging is a “disaster that you just haven't had yet”, how is it possible to keep both sets of changes easily combined? Revision control; using git's merging tools and distributed repository structure to keep everthing running smoothly.
Git-Upload-Pack: Command Not Found
This is an older post therefore the content may no longer be accurate. So you installed git and ikiwiki on your shared server and created your ikiwiki and repositories, but [...]
