project to be named later.
This post is a work in progress and I intend to make several edits over the coming days, with adding links, correcting horrible spelling and grammar, so don’t follow the thread if you are adverse to alerts when I make small changes.
This project is a bit of a stretch goal for me but hope that by publishing here it’ll keep me committed.
I really love my @torqueboards Direct Drive. They are quiet, take a beating and keep eating the watts. BUT, as pretty much EVERYONE here will attest to, I’ve got a bit of baggage (@SeanHacker - I refuse to stop eating). So this means my beloved TBDD doesn’t get the love it deserves.
The specific challenge I’ve experienced has been motors overheating when I ask too much of them - nothing like loosing those brakes on the way downhill. Particularly during the summer heat. I know, I know, @skate420 will say, “uh you ain’t seen hot until you ride here.”
I tried, in vain, to redo the build with some amazing @avx Herringbone gears and do a build for my nephew with the TBDD. Then COVID happened, @Abusfullofnuns took advantage of my moment of weakness, and relieved me of those gear drives (glad they have a good home though).
With the rainy season coming up I thought it would be fun (for me, maddening for you all) to work on tweaking my build to breathe new life into it. My hypothesis is using a higher voltage like 18s (75.6v) will generate less heat and overcome the motor heating issues experienced with 12s (50.4v) under reasonable conditions.
I’ll be logging my updates in this thread on an infrequent basis; I’m targeting better than once a month. (@Lee_Wright is rolling his eyes right now, “M8 AT LEAST once a week to keep 'em interested”).
My Goal is to reuse as much of the components and equipment I already have on hand. @tamatoa will attest that living on an island in the middle of the pacific can be as frustrating as it is enjoyable when we have to wait weeks for some seemingly innocuous thing that holds up the entire project.
Reliable, like weld the hood closed reliable. I agree with @b256 with “if it a’int broke don’t fix it” so once its at a spot where the board is working as expected, imma close her up with the intent of rarely if ever reopening that casket.
Reasonably thin: the deck i’m repurposing is quite thin so keeping a low and aesthetically pleasing profile is the goal.
Accessible what I mean here is the ability to interrogate and or make changes to the board without intrusion.
Logging Data is king, i want the ability to log issues to have educated input for targeted troubleshooting. but i don’t want the data “in my face”, yes i hear the community cries for me to cover more and more of my face but i’m speaking about when data can become a distraction. this his highly personal and i do not assert one method is superior over or another. but for me, and this board i’m thinking less of a DaveGa and something more paired down. Probably similar to what we have seen on the vaporware called FreeSk8 Remote.

Charger, - this poses an interesting problem, that has not yet been thought through. i have a 12s charger that i wished to re-purpose but clearly cannot charge 18s pack with 12s charger - can already feel this plan falling apart…

I don’t intend to do a bunch of flagging for off topic discussion in this thread but do try to keep it at least in the ball park. Unless @BillGordon shakes some sense into me - only @k00k will be exempt from said egregious off topic items.
