Kitronik produce and sell a number of light strips for the micro:bit called Zip https://www.kitronik.co.uk/catalogsearch/result/?cat=0&q=zip Huddersfield Girls Geeks chose a selection of the Arc and the Circle Zips with 12 lights for a headdress workshop. Here are some steps for connecting and coding these lightstrips. Connecting the Zips to the micro:bit Solder the Zip You need to … Continue reading Light Strips for the micro:bit
On a raspberry pi open a terminal window You need to install mayavi2 clone our cubert library from github go to the cubert folder run the rainfall simulator create your own code by editing rainfall.py These are the commands that let you do all that. To view the simulator your pi needs to be connected … Continue reading Cube: Code it yourself using raspberry pi!
I created this document for people (adults, children, code clubs, etc.) to code the cube. I will set some dates where the cube will be ready and assembled. Anyone can send me the code - send me a Direct Message over Twitter and I'll give you my email. Any code that's sent to me will … Continue reading Cube: Code it yourself using micro:bit!
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
