Any feedback on this new gearbox from SRI, the 'archimedes drive':

Think this is any easier to manufacture (the one using ball bearings demo'd in the clear acrylic) or hold up to ebike abuse?
Anyway, my kit has seen near-daily use for over a year...
A few more questions:
- I need to extend the 'speedo sensor'. Is this a normal pair of wires or is it shielded?
- In the 'battery config' screen, can I set a battery >99.0ah? Can I get an accurate battery icon without this matching my pack (120ah)? Maybe in a future release?
thanks for...
Problem:
My CA3 takes a long time to shut down.
I have it in a 72v (20s) vehicle with two Curtis 1238 controllers, who's caps I believe are feeding the CA3 when I shut the contactor off.
Is there a suggested way to address this? I've thought about inline resistors and optionally breaking the...
Excellent work guys!
I'm about to go down this path on a 24v trolling motor. I plan on using a 6s pack of (3) Nissan Leaf 60ah cells - but otherwise pretty similar to luvxu's setup. I was curious if either of you have measure the current draw and motor temps, either before or after the...
Hi.
I'm building another 72V AC powered ATV/UTV thing using Nissan Leaf packs and would like to avoid using a 12V battery.
Some setups I've seen use a DC-DC Converter with a switchable 'enable' wire (Sevcon's DC-DC, some Delta-Q chargers, etc) that will turn on the DC-DC converter when pack...
Is it possible to *input* information to the CA3 over serial? I have applications where additional information is needed and would really like to be able to have a custom field or ability to flash a text string to say the lower field of the LCD for X seconds.
I found spraying lithium grease in my thumb throttle quite helpful. The resistance was more with the plastic being poorly manufactured (like most Chinese stuff) causing internal rubbing - rather than a super stiff spring.
My Magura twist throttle was buttery smooth right out of the box.
Justin,
Are there plans to monitor cell voltage and provide cell balancing anywhere in the future? Maybe support CAN/i2c/whatever streams from other cell monitors?
I trust the Satiator to not burn down my house when charging - but without a balancing option I'm still stuck with questionable...
Dave and a few others have mounted their Tangent kits within the Triangle. Seems to need a Horst link style aka VPP suspension frame where the pivot is behind the BB.
Motors on the swingarm seems to be the ideal solution, but not something you can do without a lot of fabwork for a custom frame.
The prototype LMX is still one of the coolest looking ebikes to date. Love the progress and all the videos. Keep it up! 8)
I based my latest build around Hope Mono6Ti 225mm front and back - because, well, 6 pistons are awesome and I too prefer rear braking vs lots of front fork dive...
Any more pictures, this looks rad.
Did you mill the traces or use a photoresist? Any plans to sell kits/opensource? Voltage or discharge time adjustments?
