Digital video cameras can pick up high freqs sounds really well

Mark, your wish is my command!
I got an inner ear infection on that last day of work, haven't been able to get near it to solder the last three wires until today...
On the maiden voyage, I didn't want to go very fast because the brake booster isn't hooked up yet (I need a 3/8" to 1/2" hose adaptor) and until I repair the burned wiring on the taillights I can't hook up main system power - brake lights, turnsignals, etc.
Changing gears was easy - THE CLUTCH WORKS without a pilot bearing! It pulls away in first gear better than the old ICE did, but it felt like it was running out of ooophm at the magic 25mph mark. OTOH the ICE was slow to build speed too, and I didn't take the time to push it faster without vacuum assist for the brakes.
After making the video, I also soldered up my Jumbo Cycleanalyst, now I finally have access to the information I am used to, the data I need to see how the batteries perform. I think I'm just gonna talk to Victoria and get another batch of cells now, and take it up to 96v since I already have space in the battery tray. I have a feeling I'll get another batch after that and bump it up to 144v... then 180v...
TD, you were right - it was darn near silent inside. I was suprised to hear how loud it was in the video, but I think that is just tranny noise.
It's short, but so is life so enjoy!
very pleased to see the video of your electric car with our Headway LiFePO4 lithium-ion battery.

http://ebikes.ca/drainbrain.shtmlBy default, this unit is supplied in the High Range mode (resolution of 0.1 A instead of 0.01A, and display readings in kW instead of watts) and the shunt is set to 0.500 mOhm.
Jd, could you test that... "For the science!"

Yes use aluminum cutting oil else the aluminum gauls the tap binds and breaks
dnmun wrote:JD, you can use self tapping screws. if it is thick plate, predrill to applicable size and drive them in with a driver. most aggressive would be the joist hanger screws because they are super strong and have a serrated edge to cut into wood since they are self tapping but 1 1/4" long, depending on the load, you could likely use 1/2" zip screws with hex head, 5/16" driver. lotta luminum in there now. you should be able to use non vacuum booster brakes, i think the older vans did not have vacuum assist, or maybe you could find another master cylinder without assist and hack it in.
