Current state of things with a small test board on the right, and a test board pretending to be the scalextric base unit on the left

strangely it works, need to hook the right hand bit up to a real scalextric base and see if the two play nicely

with only minimal swearing and needing to swap two wires round and only a few sacrifices to assorted dark gods who just happened to be passing* its working, the little test device can talk to, and control the scalextric power base, which means I should be able to get my actual lap counter box to do the same over the next few weeks.

key is the "fake C7042" box will gain the ability to play piggy in the middle and will eventually have the ability to override throttle inputs, which makes it perfect for driving ghost cars at a fixed speed around a track to generally get in the way, or say for running in a new cars motor

* its Cudworth, there are always a few of them loitering, building courage before heading to Grimthrope or Lunwood

its currently blasting out a mix of Roxette and Fleetwood Mac

slight offshoot of all this... have added a little 128k memory chip, as such can now record about 60 or so seconds of data...

while its pretty basic at present and needs something to load and look at it properly it would seem this has evolved a basic telemetry system so you can see reaction times and similar
