I'm going to make a demo one that i can take around and show people, then look at getting some circuit boards printed up for them :)

How i made it.

I take a 240vac to 5vdc transformer, power up a small microphone then run the output through an amplifier circuit and into my Microprocessor.

Inside the Microprocessor I've written some code to look at the shape of the voltage spike and determine if it's a clap or not.

If it sees a clap it starts a timer that waits for the second clap. If all the parameters are met eg, amplitude, frequency (sharpness) and time between claps, the Microprocessor switches a relay on which switches the light on...

All of this fits in behind the switch plate on the wall and there is an extra switch that houses the microphone.

The first Version of software started switching on the lights with coughing and laughing and stuff. But Version 2 seems rock solid so far!

Hopfully i can make them quickly and package them nicely for around fiddy bucks. depending if anyone actually wants one of course...

What do you mean by fixed lighting? Given that I can switch a relay with sounds waves, I'm pretty confident I can switch anything with just about anything :)

nvm, I think I answered my own question just after I asked it anyway :P

Is there a Marsupial in the House???

You Bet your ARSE!!!

Took us a few weeks to prove to the realestate that we had more than just mice in the ceiling, but there aint no doubt now! :nyaanyaa:

Little Bastard chewed a decent hole in the fascia board and punched through the air vent in the ceiling, leaving a bit of a trail and a small gift.

Moving house in a week so... Meh... Whatever.

Sure did! Webber got away clean.... then I started to worry cos you can only go backwards in placings from there lol.. wasn't sure he'd be able to keep it up till the end but he did YAY!

Can't believe I haven't seen a GIF of when he sprayed himself in the face with champers yet :D

I think he played it pretty safe, didn't risk trying to build a gap or anything, which to be honest is pointless because of the high chance of a safety car to spoil it, a very mature drive. BRING ON CANADA!

as for the gif, its only a matter of time!! lol.

Yeah, and I liked his little comment in the press conference about the team strategy, basically saying that if they'd ripped him off and somehow given Vettel the win "that's not what was supposed to happen" or something along those lines. I love how he's not afraid to say things, and he does it really subtly so it doesn't sound like he's bagging his team or team mate :laugh:

Oh and:

Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!
    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
