As I have mentioned previously I've started amassing parts for a bike wash install. Today I stripped down the broken Bosch Fontus low pressure cleaner and harvested all the useful bits. Here's what I'm left with...
The over-wheel arch tank has also arrived...
I've also pinched a handfull of resistors that I'll need to trick the electronics in to operating without a proper Bosch battery attached - theres a coding resistor and an NTC (heat sensor) inside the batteries which the electronics check are connected before they'll activate. By connecting those pins to ground with the correct resistors you can recreate a plausible signal and trick them in to thinking it's connected to a battery and then feed in an external +19V to power it, which in my case will be provided by this nifty little DC-DC converter hooked up to the leisure battery...
I'm not sure when I'll get a chance to start playing with these bits and working out where best to put them all but I'm already looking forward to it
