Paris, you've got my vote!

Electric Cars are for Girls

Since John McCain recently mistook Barack Obama for Paris Hilton (hey, that could happen to anybody, not just the elderly), Paris assures America that she is "totally ready to lead.". Me, I'm totally ready to be your VP, girlfriend. Call me.) Okay, if you're asking yourself, what's that got to do with electric cars? it's in Candidate Hilton's energy policy; she advocates tax incentives to build hybrids and electrics, among other things. It's in the campaign video, check it out

Rotating the Brushes on the Warp9 Motor

Open Source Civic EV Kit

Many people don't realize that the Honda crankshaft going into the transmission actually turns clockwise for the forward direction, as opposed to counter-clockwise for the vast majority of cars. As such, most EV motors have advanced timing on the brushes to optimize counter-clockwise rotation.

DIY Electric Car Highlights and Progress

DIY Electric Car

The DIY website has been going under some pretty impressive changes and has included some pretty interesting threads over the past few months, but with over 3000 members and an average of 400 new threads a week there is a lot of content to go over. So I thought it would be helpful to pick out some of the highlights of what I have found to be the most interesting threads and developments of DIYelectriccar over the past few weeks: Tags: Editorials highlights forums wiki garage

Motor temperature sensor

Honda S2000 EV Conversion

The FB 1-4001 from Advanced DC motors is far from having all the bells and whistles you'd hope for. In fact the only sensor it has is an on/off over heat sensor that is open until the temperature has risen too high in which case the circuit closes.

Picking an Accessory Battery

Open Source Civic EV Kit

Given the limited space and mounting locations in the engine compartment, I tried to pick a 12V accessory battery that would be the most optimal. The original 12V battery from the Civic was just too big to fit anywhere useful. I ended up deciding on the YIX30L battery from Yuasa.

Transmission Dowel Pins and Alternate Vacuum Pump

Open Source Civic EV Kit

In the process of removing the engine from the transmission and selling it off, I lost one of the critical alignment dowels that mates the adapter plate to the transmission housing. Apparently, you can see if local Honda dealers have these parts in stock by browsing the catalog at [link] My local dealer had three of of the alignment dowels. Part number is 94301-14200 and the dimensions are 14mm dia by 20mm long. I also received an e-mail from Paul Pancella who is converting a '92 Civic Hatchback.

Adapter plate and coupler status

Honda S2000 EV Conversion

As I mentioned before I wasn't sure which route I was going to take on getting the plate and coupler made. For my setup it turns out I need six pieces machined total. The coupler which mates the motor output shaft to the original flywheel. The flywheel has the clutch attached to it which then slides over the input shaft to the transmission. The adapter plate is the second piece. It needs to be cut to match the outline of the transmission and have all guides and bolt holes drilled out.

EPS DTC Codes

Honda S2000 EV Conversion

So after doing some research on why the EPS light would come on it's exactly like a check engine light. There are a set of codes that can be displayed to help diagnose problems with the system. The bad part is you can't use your standard cheap OBDII tool to read and clear these codes. The only scanners that will work for sure are from Honda and you can't buy them. There are some 3rd party scanners that cover most of the functionality and on average you can own one for 5k.

I finally got the new handheld oscilloscope in to try and figure out what I was doing wrong in creating the RPM signal for my gauge and to enable the electronic power steering to work. The scope is a Velleman HPS10 and I picked it up new on ebay for $140 shipped. I didn't know what to expect never using a scope before but looking at the features I was pretty sure it would do what I needed. I'm really impressed with this scope for the money after using it.
