My original design for a turntable is taking off. Small scale production is probably coming…

Das FrankenTrike

Some time ago I had the idea to build an electric car (EV…)  for my kids to ride. Something simple, but that would allow them to go faster than the typical electric toys that you can buy at Toys-R-US…

That was 18 months ago, and due to other “higher-priority” projects, only now this has reached fruition.

In the meantime, to simplify it, I changed from a car to a trike as the steering became a lot simpler. I reused most of the frame from a pedal-trike, but turned upside down.

Power comes from a 14.4V portable drill spinning directly one of the rear wheels. The throttle is a re-purposed bike brake lever and notice the “range-extender” extra battery velcroed to the back.

DSC_8857DSC_8856Missing still is a forward/reverse lever, as pulling/pushing a button on the back of the car requires some contortions. A cardboard body is in the works, too, but that’s the kids job, they have to do something, right ?

As for brakes… who needs them ?

Elektro-WUR (or DWUR v3…)

Finally I’m running a Digital WUR (reliably) on my 911 ! For those wondering what a WUR is, take a look here and here.

Thanks to good friend Steve at Reanimotion, I was able to get hold of a prototype measuring block for his new Franken-CIS system. Basically, the idea (not new) is to use a pulsed injector (using a PWM signal) to define the control pressure on a CIS /K-Jetronic system. I used an injector from an Impreza, as it has to be a side feed injector with a reasonable debit rate.

From there, you can make things more complex if you want, or as simple as possible, as I did. That was my intended approach, as my 74′ 911 has one of the earliest (thus simpler) implementation of the once extremely popular Bosch CIS system.

So I proposed Steve to prototype a bare-bones approach, using a very simple controller to read the engine temperature upon startup, and from there, select a starting control pressure. Afterwards, for a maximum of 4-5min the pressure progressively rises until it reaches the desired warm control pressure.

The controller itself uses a PICAXE 18M2 MCU, with one of Revolution Education own starter kits, the CHI030. Really simple…
