I want the cube to be programmed by children of all ages. It can be coded using makecode blocks and the micro:bit. But for the lower ages, I wanted something as simple as colouring in squares in the grid. This was take-1 of using excel to code the micro:bit https://www.youtube.com/watch?v=GqDwi85lWU4 And the final result https://www.youtube.com/watch?v=ll-fYfYmcX8
The first few prototype columns were wobbly but it wasn't just the weak wire. The ping pong balls were not aligning properly. We tried printing a 3d case for the ping pong balls to align the drill holes. https://www.youtube.com/watch?v=Ww_TZ4nt0fs https://www.youtube.com/watch?v=sXD-mPm1y_U After doing about 50 it was only then we realised they still weren't … Continue reading Cube: Post 4 – Failing
After the great ping pong failure of January, we splurged on a new toy: a CNC milling machine with a laser engraver. This made drilling accurate holes in the ping pong balls much easier. We built a wooden holder with 3d printed clips to hold 8 balls. We programmed the miller to drill 4 holes … Continue reading CUBE 5: A new toy!
My husband and I were thinking about saving for a laser cutter. They are really expensive (£3,000+) but we REALLY want one. After lots of searching my husband decided to buy this CNC Milling Machine and Laser Engraver: https://www.aliexpress.com/item/2016-New-GRBL-CNC-machine-3-Axis-Pcb-Milling-Machine-2418-Diy-Wood-Carving-Mini-Engraving/32702214289.html It was delivered via Fedex from China with full tracking and texts. There were no extra … Continue reading CNC Milling Machine and Laser Engraver
The PCBs arrived! https://twitter.com/LMcUnderwood/status/953991535871262720 I'll post their design on here soon... To solder the light on I used trusty blu tac. I put a blob on blu tac on the table and placed a board on top I placed a smaller bit of blu tac on top of the board I pushed the light into … Continue reading CUBE: Post 3 – Soldering
From scratch I made a whole column of lights using the stripboards This made me realise how BIG this project is going to be! https://twitter.com/LMcUnderwood/status/951444726967947265
So the wire I ordered was completely wrong. Copper wire is WEAK! And exactly what I don't want. This week I've gone with 2.5mm wire from screwfix: https://www.screwfix.com/p/apollo-2-5mm-2-5mm-galvanised-garden-wire-x-25m/57999 We used this YouTube video as a guide on how to straighten wire. It worked really well and was LOTS of fun https://youtu.be/b4-QF-WRFjQ We then created some … Continue reading CUBE: Post 2 – prototyping
