Probably this issue has been fixed - http://www.dsprobotics.com/support/view ... =2&t=64184

Sorry for the confusion!

We were unable to moderate but now Malc has fixed it.

No problem - I've worked as a production-line machine operator many times, so I'm quite good at running repetitive mouse clicking as a background task! The most annoying bit was that a couple of hundred of the 1300+ spam threads were that bot which always posts "Where is administration at dsprobotics.com?" - that felt a bit close to the bone given the circumstances, and I was starting to take it personally!

I remember the very first time that question was posted, because I thought it was genuine so I responded with helpful comments.

I'm inspired. I'm going to start work on my Flowstone Automatic Car Driving schematic tomorrow. I'll hook it up to the motor over the weekend and we'll be bombing up & down the M5 in no time, you'll see

.

Otto will do all the driving, and I'll sit in the back with a laptop and try and fix the bugs

.

I mean, what could possibly go wrong?

Make sure the "side of street" Ruby input is clearly labeled so I can invert it before beta-testing.

It might not be such a complex problem as you think...

Thanks Trog, essential stuff. I'm getting there, this oughta work ..

Code: Select all

def init
   t = 0
   @applyBrakes = 0
   @applyThrottle = 10.5
   @sideOfStreet = @sideOfStreet * -1.0   # cheers @deraudl :-)
end

def brakes(howHard)
  @applyBrakes = (@2Fast && ~@2Slow && ~@nietzscheanTractorTrailer) * howHard
end

def throttle(floorIt)
  @applyThrottle = @applyThrottle * floorIt
end 

brakes(t)
throttle(t)
@reverseGear = @nietzscheanTractorTrailer & (brakes>11)
  if @reverseGear
     @brakes = 0
     @throttle = 11
  end
t = t + 1
output 0, @throttle
output 1, @brakes

Just got the steering bit to sort and I reckon we're good to go. I just wish low-pass filters were this easy

I should have the pedestrian-targeting module up and running in a day or two...
just need to disassemble and reverse-engineer some Space Invader code.

(Probably won't need DSP or ASM for that: they're not all that agile.)

Just the easy stuff left to do, then...

The code for the bonus flying saucer might be useful for slightly faster targets, too - e.g. the hooligans who race stupendously loud quad bikes around our local roads in the early hours of the morning (mind you, they are very community spirited - I saw a few the other evening all wearing their Covid masks while still rebelliously omitting crash helmets!)
