Month updates from November & December 2024 - what's been going on around Sheffield Hackspace? |
What have members of Sheffield Hackspace been up to this month?
Let's find out!
- Nik - window decoration
- Nik - an LED device
- Alex - a trip to soft lab
- James - 3D printer in a backpack
- Adam - organised electronics
- Tom - darning repairs
- A member - silicone D20 mould
- Dave - CNC machine calibration
- alifeee - CO2 monitoring
Nik has laser-cut a hilbert curve that fits neatly as a window pane decoration. See more on Mastodon: https://mastodon.social/@nnenov/113380244822759727
Nik has also been learning PlatformIO. They used it to program an Arduino pro micro with an 8x32 matrix and the fastLED library.
It's the first electronics thing I made which is not a sprawl of cables and just one single cable!

     Alex has been exploring weaving and knitting structures, coding in knots, textile motifs as symbols, bitfields, rhythm, movement, liveness, and the internet of patterns on a residency in Eindhoven.

Also see a paper from a few years ago about a mini version, also by Alex https://zenodo.org/records/3939176.
   James went to SMRFF 2024, a 3D printer festival in Manchester, for which they made a 3D printer which works in a backpack!
Adam has been organising their electronics with 3D printed inserts.
 Tom bought a darning loom and used it to fix a hole in their jumper.
  One member designed and made a silicone icecube mould. The mould geometry was designed in CAD and from it, a mould for the silicone was created. This 3-part mould was 3D printed using PLA & PVB. The printed mould-mould was assembled and a 2-part foodsafe silicone was cast into it.
 Dave from Desktop Machine Shop has been rebuilding a CNC machine...
I have just rebuilt the Milo v1.5 CNC machine with some upgrades:
- new more capable control board running RRF
- 55v power supply for motors to increase speed and torque
- new safety wiring so that SSRs are used to kill motor and spindle voltage without running high current through the e stop
The machined star was just me testing out that everything was working after the rebuild. But it will be a Christmas decoration when I'm done. I'll drill a hole and pop some ribbon through it

See a lot more information in the relevant GitHub repositories:
