So I am doing a bunch of updates to my current board so I am going to continue my build thread here. Here is my previous topic: https://www.electric-skateboard.builders/t/monster-board-trampa-holypro-35-80100-180kv-8kw-fatboy-ss-gear-drive-12s-3p-18ah-dual-focbox/36560
So current setup looks like this:
- Trampa Holy Pro 35º Deck
- Trampa Spring Trucks
- 8" Wheels with FatBoy Solid Wheel Hubs
- Enertion Nano-X Remote
- 2 x 80100 180kV 8kW APS Motors
- 12S 18Ah 65C (3P x 4S x 3S 6Ah 65C Turnigy Graphene Lipo Packs)
- 2 x VESC 6.4 based ESC (FocBox Back up) Running ±150A Motor ±120A Battery settings (Yet to test new esc)
- FatBoy ESC MTB Case (with WS2813 RGB strip embedded in plastic)
- Custom made Aluminium + 3D Printed battery case
- 4 x addressable RGB light strips (WS2813 based)
- 200W 5V DC/DC and 400W 12V DC/DC baseboard with GPS module
- NanoPC T4
So I started working on board again yesterday, spent whole evening trimming and shortening RGB strip for ESC case was sticking up too much and was bit scared that it would short something as RGB strip is basically copper exposed on the sides. While mounting realized that few phase wires will get in contact with rgb strip and can maybe cut through isolator and short something so I split strip in few places was bit pain in the ass to join it with wires.
I glued it in with hot glue
Quick Arduino sketch to see if it still works (slimmed that strip way too much :D)
Also made an extenson on the enclosure so I could remove heatsink with esc without need to mess with wires and etc. Takes a bit of time to solder all those phase wires to the bullets and heat shrink them.
Y splitter for new ESC’s and soldering bullets to phase wires.
Talking about new ESC yesterday I received prototype VESC based on 6.4 so will be putting a thorough test on the journey to Paris (Also will be taking my original focboxes as a backup just in case pulling around 25kg dead weight is no fun at all)
I am making everything easily swappable if something happens so I had to put connectors for buttons and etc stuff and also duplicate for focbox heatsink too
Because of lack of space in ESC enclosure, I will be moving all Esk8thuino and etc stuff to battery enclosure, so from ESC case I have to route out RGB wires, button wires, USB wires, uart wires, ppm wires back to the battery so a lot of wires to make.
I will be using a bit modified latest vesc firmware with slow mode (default current settings) as a default setting and will be attaching nano-x second channel (toggle output) to SWDIO pin which will enable original high current configuration. This will let me easily turn on high power mode without phone or etc.

For battery case I have designed an aluminum/ 3d printed part combo last weekend designed these plates and asked father to machine them for me and yesterday I received them looks pretty sick sadly there was not enough time to anodize aluminum so will be using it raw but I think it looks good in raw too will match wheel hubs.
Yesterday started printing the middle part from scratch as this is failed was printing at 300% speed was going really well until 70% when I went to bed and it managed to have few layers splits and is not okay so ordered new bit nicer looking red PETG filament and started printing again.
Electronics will look something like this:
I have already ordered PCB for DC/DC converters and Esk8Lightuino should arrive today
Today will probably continue working on electronics, and tomorrow with mechanics.
I have a new grease we made received so can’t want to try it on my own board to see how it works out and sounds.
