Anyone know other ways to contact tumich? I've sent some PMs because I'd like to purchase some cells, but I think he's not getting the notifications and he hasn't responded for a couple weeks.

I've never seen a difference that big, but a while back I noticed a similar problem. I'd been having motor cogging problems when the VESC switched between sensored/sensorless during acceleration. I played around with the sensorless ERPM value. I found that forcing the VESC to remain in sensored...

Lithium battery recycling is being doing commercially already: [youtube=Bpe8HalVXFU]

I have a similar active balancer, but the 4s version. I stuck it on a 3s lipo that was out of balance and it was balancing it, no charger connection needed. This would have been at more like 3.5V/cell. It did the job, but I think it only balances to within 0.1V.

Take a look at these holders. It's a parametric design where you can customize how many cells the holder should have, what size they are and much more. This design started here on the ES forum but it's been extended quite a bit, it can even generate matching covers and boxes.

Windows update might not be finding new drivers, but there's a chance they're still out there somewhere. I found a forum post with a link to the driver: https://www.tenforums.com/graphic-cards/157576-working-driver-mobile-intel-gma-4500mhd-windows-10-a.html But it's hosted by a third party, so...

Can you update your GPU drivers? OpenGL 2.0 came out a long time ago, hopefully there are updated drivers available for you. It might help to know what laptop model you're using.

:lol: It's funny seeing this here, I saw this truck for sale on craigslist and considered buying it, but I wasn't sure how practical it would be to drive. Good luck with your project, it would be cool to see this thing rolling again under it's own steam.

Yeah, it could have been poor contact or some other issue, but bad wires are still possible. I've had test leads with 24 AWG copper inside. A 3 foot set of those would be in the ballpark to drop 0.5V when you factor in contact resistance as well.

It's not false, it's basic electronics. How about you provide some kind of reasoning or proof before you go around mistakenly telling people that they are wrong?

I'd recommend getting some better leads for that power supply. If the power supply is putting out 4.2V and 2.5A, yet the voltage at the cells is still 3.69V, that voltage difference is being wasted in the wires. With better wires you'd be able to put out higher current with the same 4.2V setting.

I don't know what the protocol is, but I would hook up a USB UART adapter to the display and start sending it some data to try and figure out how the protocol works. In the captured data you have 0x5A and 0xA5. 0xA in hex equals 1010 binary, 0x5 would be 0101. These values are commonly used to...

Thanks for looking into that. I really like the idea that Xenforo can preserve external images. That would have been really useful when ElectricGod nuked all the images in his posts...

I doubt this is a viable solution, but it's what I use for my self-hosted stuff because my ISP doesn't allow any email sending. I just created a gmail account to do the mailing and set up my scripts/software to use the gmail account when they need to send out mail. It works for my small scale...

I think I had only clicked on the first image and found that it was a dead link. Both thumbnails appeared broken when I visited that thread.
