+What have members of Sheffield Hackspace been up to this month?
+
+Let's find out!
+
+1. [Nik - window decoration](#nik---window-decoration)
+2. [Nik - an LED device](#nik---an-led-device)
+3. [Alex - a trip to soft lab](#alex---a-trip-to-soft-lab)
+4. [James - 3D printer in a backpack](#james---3d-printer-in-a-backpack)
+5. [Adam - organised electronics](#adam---organised-electronics)
+6. [Tom - darning repairs](#tom---darning-repairs)
+7. [A member - silicone D20 mould](#a-member---silicone-d20-mould)
+8. [Dave - CNC machine calibration](#dave---cnc-machine-calibration)
+9. [alifeee - CO2 monitoring](#alifeee---co2-monitoring)
+
+## Nik - window decoration
+
+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 - an LED device
+
+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 - a trip to soft lab
+
+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.
+
+See more on Mastodon: <https://post.lurk.org/@yaxu/113485978426705451>
+
+Also see a paper from a few years ago about a mini version, also by Alex <https://zenodo.org/records/3939176>.

+
+## James - 3D printer in a backpack
+
+James went to [SMRFF 2024](https://www.sanjaymortimerfoundation.org/smrrf24), a 3D printer festival in Manchester, for which they made a 3D printer which works in a backpack!

+
+## Adam - organised electronics
+
+Adam has been organising their electronics with 3D printed inserts.

+
+## Tom - darning repairs
+
+Tom bought a darning loom and used it to fix a hole in their jumper.
+

+
+## A member - silicone D20 mould
+
+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 - CNC machine calibration
+
+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

+
+## alifeee - CO2 monitoring
+
+Finally, I set up a [SCD40](https://sensirion.com/products/catalog/SCD40) CO2 monitor in the space, and attached it to the old train sign.
+
+See a lot more information in the relevant GitHub repositories:
