Time Log


Fri Jan 6 2023

  • Started again on the UELVEs_MBC. PVC pipes and bamboo,

with 3D printed nodes, kevlar cloth and FR4 Resin.

Sun Jan 19, 2020

Wed Jan 15, 2020

Open_Source_Battery_Pack needed way to generate STL files (added). edited STEAM jan2020 page, mentioned TODO items.

Fri Jan 10, 2020

UELVEs_MBC 3D geometry drawing and preliminary result, showing how, based on four node locations and assuming the distance between door frame (purple) and door sill (green) is parallel, create a "marker" line half-way between, and work out the angle from which the pipe may be rotated (from its node) such that *both* pipes will touch perfectly on that centre line. by keeping things in 2D, it turns out it simply involves a couple of calls to atan2

UELVEs_MBC video explaining an issue that needs solving with some 3D geometry algorithms. The doorframe, doorsill and the door itself, all those pipes need to be parallel and a set distance from each other. This should be easy to compute with the application of some simple 3D algorithms, if you know what you are doing... I could really use some help here.

Sat Jan 04, 2020

Open_Source_Battery_Pack nearing the point where it can be test-printed. this shows the bus-bars and wires (yellow) which have poron foam behind them to act as springs, creating electrical contact *including* from the lid (purple) to the main holder (green). i also added space to get access to the BMS PCB (red) where you screw down a lid, it was becoming too awkward for assembly.

HintLightbulb.png Hint: This is an open source project, where is the source file lol!

alrightalright, i hand-drew it in the gimp! :)

Toblerone modifications proposed to D3D Universal which will allow it to span a greater distance without flexing.
