Not quite what I’d expect from what I assume were pretty expensive hubs.
Looking good so far! Keen to see the complete harness for all the lighting… I feel like you’re gonna be fighting for every mm² inside that enclosure!

Im using non-standard bearings. 28mmOD 10mm ID. Most skate bearings that vendors sell are either 28x12 or 28x8. Not sure why mine didn’t fit right away but I bet the skate ones would.
I put the esc in the enclosure and like, sheesh these go-focs are small. Even more confident that the 16s6p will fit now, but all the lights, switches and buck converters will definitely eat up all the space. Might spend a couple hours tidying up the wiring

3ds machines the seats super tight, I wasn’t able to remove the standard 608 bearings on mine by hand as well

Will the lasers possibly be shooting people in the eyes when you turn?
2 Likes
Most likely not. The laser holder will be angled downwards and to the back of the enclosure, so when turning, the laser will widen out, but not enough to even be horizontal to the ground or be pointed upwards.
The holder will be pretty similar to Lorentz Majors version. I’ve seen videos of their lasers and during turning the lasers don’t come close to being a potential hazard. I’ll have a switch to turn them off while I’m picking up the board, cause that’ll be the only time the lasers will be potentially pointed at eye level.

Quickly soldered up a circuit for the lights in the board. Holy shit I didn’t expect it to work this well, thing’s beautiful. Only issue I encountered was that the momentary switch didn’t want to work with either the Normally open or closed connection, so I had to switch to a latching one… I’ve got like 6switches lying everywhere .
The solder connections and general wiring is messy asf but for a quick mock-up, it’s worth the fire risk. I’ll need to clean everything up and waterproof/secure things heavily when it’s ready to be put in with the battery. Adding jst connectors for each connection for easy maintenance. Last thing will be to print a final design for the laser holders then bond them to the enclosure somehow.

Rough visual of how they’ll look once everything’s done. During proper nighttime these will be very visible. I’ve adjusted the current from the driver so that each laser gets runs at 40mW each, very safe.

Been awhile, but got some nice updates on the build. P42A cells arrived, all tested and in really great condition.
Unfortunately all these perfectly good cells are completely useless to me at the moment. Right after receiving these I saw that P45Bs dropped in price quite a lot. I paid $1520 NZD for these p42s but the P45s I just ordered were $1488. These are directly from Molicel. This upgrade should give me 7km extra range, giving me a total of 97km based on my average wh/km consumption.
The next issue was how I’d fit such a big battery in such a small enclosure. The Hummie deck is routed out and can fit 84 21700 cells with a double-stack staggered battery. Some extra routing on each end should increase the cell amount to 96 cells, so that’s exactly what I did.
I routed 15mm on the front side, and 10mm at the back. The front can get 5mm of extra routing if more space is needed, but there should be enough for the battery, bms, esc, cable/wiring, buck converters and the lasers on the sides.Time will tell how well the deck will hold up for strength after this routing, so I might order another Hummie deck just in case. Next up will be the battery build.

directly from Molicel[/quote]
I was under the impression that Molicel don’t sell small qty?
This was from a bulk order for me and another guys build. May have been around 200+ cells and some more for the builders other projects.
Small qty = under a million cells per year
Ahh, I’m not sure if that’s the case then. All i know is that they ordered 620cells from Molicel, and for basically the same price as a P42 cells . I definitely won’t complain about this bargain though.
Alarm bells ring for me when people say they bought direct from molicel because as far as i’m aware, its just not possible unless ordering enormous qty.
In any case, i’m jealous. I want p45b

Group buy? What’s the best price you’ve seen them for here? Shipping from 18650 is balls.
I haven’t looked, apart from checking if vape traders have them.
Shipping from 18650 used to be pretty expensive back in the day, but I thought they stopped shipping to Aus completely a couple of years ago.
Getting legitimate Molicel in Aus is hard. Its Vape Traders or nothing as far as I’m aware.

So i just checked out shipping from 18650… landed price isn’t actually too bad.
For 100 cells, its something like $13.50 per cell
For 200 cells, it works out a bit cheaper at roughly 12.50 per cell.
I guess the more you order to counteract the exorbitant shipping, the less you pay per cell.
Considering that p42a are somewhere around the $10 mark here, the price isn’t terrible, and to be honest, I’m not sure what other options we’ve really got.

Is that adding the 15 percent tax once you get over the 1k aud mark though? I sent them a message asking if there were shipping alternatives but no response
In my experience, they value the package low to avoid tax

Oooh that’s nice of them
Build was on hiatus as the P45s were stuck in customs… The builder has started on the battery, doing a great job despite the space constraints.
It seems the routing I did was necessary to get enough space for the d100S and 16s Daly and accessories to fit at the back. There’ll be juuuust enough space on the sides + enclosure to fit the buck converters, Bluetooth receivers and LED wiring. If my measurements are accurate (which they have been up till now) I should have space for the charge port, power button, and led switch with some strategic positioning. I’ll be to trimming the ESC lead and motor phase wires to reduce slack that would otherwise take up space in the enclosure.
