    SCORE!!!! Craigslist find

    Do you have the THM425 trans? Is it flipped front-to-back? I'm designing a different (flipped) arrangement, using the trans but not the diff - a short driveshaft will go back to a radically offset Winters quick-change, supported on a conventional four-link and Watts link. This approach gets...

    Still got tons of stuff - anyone near Atlanta want to make a great deal for all of it? I need the space! Forrest

    FrictionFast Bike project

    Hey - anyone interested in this for free? It needs a 36V 40 A controller (old, used one caught on fire!), but else is fine. Projects have moved on, and I just hate to see this fun ride not being enjoyed. Free for pickup to the first interested party, with extra AGM batteries and enough NiCad...

    Honda Accord build - starting now

    Man, I'm having trouble making the battery purchase. I'm investigating some interesting new technology for a very large application at work, and I just have this fear that batteries are about to be old-tech. Forrest - conflicted

    Honda Accord build - starting now

    Interestingly, the skirts are worth an honest 2+ mpg - First fill-up last night appended to bottom of list below; the whole tank was with the new skirts; same commute, same speed, same gas station, same pump even as I usually use. 345 miles; 12.927 gallons  26.7 mpg (first recorded; tires...

    Honda Accord build - starting now

    Thanks! Here's moments ago - working on the aero now before I do the converstion; just put these skirts on - I still have to put pieces behind the rear wheels, but am running to the hardware for more screws. All the skirting came from one 8' piece of 18", 5-layer neoprene and fabric...

    New EV Profiler; a rentable driving analyzer

    Darned interesting results below from identical morning commutes. In the first graph, I just drove with traffic on I-20 (which is most of the commute); maintaining a speed of 76-82 mph for that part of my morning commute. That used 115% of a Nissan Leaf battery to go 64.6 miles. Assuming a...

    New EV Profiler; a rentable driving analyzer

    I'll update this thread as well as my Honda Accord conversion thread. The EV Profiler is working well. I get an e-mail each night with the (below) graphs of my daily travels. What I've learned immediately is that a Nissan Leaf (21 kWh battery pack) or Ford Focus EV (23 kWh) won't carry me...

    Honda Accord build - starting now

    That would be a Leaf + $12,000 and another 500 lbs and where to put them? Not that I haven't thought about it! Forrest

    Honda Accord build - starting now

    I'm glad you asked that question! Yes, my batteries will be almost as much as a Leaf - it lets you know how much the car companies are subsidizing their electric vehicles! I mentioned in another thread I was getting an EV Profiler - I did, and I'm using it. Attached is the report link from...

    Here's an interesting reality-check of the whole EV conversion idea for those who might be new at looking at it. This is a complete quote from a reputable company for all of the pieces I will need to peform my EV conversion. There are two caveats - I still need to make / source a motor mount...

    Gears used in this electric supercar...please explain.

    That's what I want to find out first-hand, with a car more like what we all might use! Forrest

    Gears used in this electric supercar...please explain.

    I've wondered this myself, and will be able to actually experiment. I'm converting an old Accord to an EV, using the stock transaxle and clutch. I have a G-analyst, so I can easily graph acceleration. I'll try acceleration runs with the car just in third gear (~1:1), and then compare that...

    Electric goKart for SCCA solo2/autocross

    TheSuperKids has a nominally-rated 1500W motor and Crystalyte controller for ~$300. I've bought got the pair; unused as yet. The information I have is that the controller will handle 72V and 55A (~5 HP), which is my goal for it. Forrest

    New EV Profiler; a rentable driving analyzer

    Just saw this product http://www.123evp.com/Home.aspx in GizMag this AM; realized the company is in Atlanta, called and ordered one. Basically, it's a device that looks like a radar detector, that you rent from an auto dealer or from the manufacturer. You stick it to your windshield, plug it...

    I just used an un-modified 250-Watt 24V motor - most any scooter parts place has them for $12-$35 new. PM me for used ones I've got cheaper! Forrest

    Generating power from children - like the Matrix

    Yep, it'd just be crazy not to do that. I'll start experimenting on the kids with those muscle stimulation things in the back of Pop Sci right away. Forrest

    Generating power from children - like the Matrix

    The kids were excited; wanted to see what they could power - they found they could run the hand mixer - http://www.youtube.com/watch?v=8DDfMqWsPnI They convinced my wife they could mix long enough to make cornbread - so that's what we had for Sunday morning breakfast. Next, they ground...
