This is a question DIY Techno-hacks

Old hard drive platters make wonderfully good drinks coasters - they look dead smart and expensive and you've stopped people reading your old data into the bargain.

Have you taped all your remotes together, peep-show-style? Have you wired your doorbell to the toilet? What enterprising DIY have you done with technology?

Extra points for using sellotape rather than solder.

Wank alarm
When I was 11, I was into electronics. My best ever project was to install Maplin type pressure pads around the house under the carpet, and wire them all up to little light bulbs, attach all the bulbs to a wooden board, and label them with their locations. I did all of this when my parents were out, and for years, I could tell where people were in the house - roughly. As I became a teenager, this actually proved fantastically useful as a rudimentary wank alert, and allow me enough time to hide my tadger should anyone head toward my bedroom door.

I moved out of there 20 years ago, but bought the house off my parents about 5 years ago.

Funnily enough, the system is still there, and god bless, it mostly still works. As my old childrens bedroom is now my grown up office, it still performs the exact job it did all those years ago. Only it now warns me of my missus' approach. I'm never going to reveal it to her but I shall pass it on to my son one day.

Boys never change do they?

You should wire it to a wireless keyboard key that minimises all windows!

You could make a fortune selling that!

Your son will either love you
Or fear you.

Modern Version
I am currently designing a very similar system which interfaces any intruder alarm system and takes advatange of the PIR sensors to do pretty much the same thing but with a Serial Interface to a PC as well as independent LEDs.

Does this not mean that you have to wank over a series of lights though..?

And it's a system which clearly has longevity too.

I used to have a similar system
lightbulb, attached to PIR sensor at the top of the stairs, with optional buzzer for added attention-gettage.

Unfortunately, the one time it could have been useful, the buzzer wasn't on, and I was too busy concentrating on the girl with her head bobbing up and down in my lap to pay much attention to the lightbulb. My brother walked in and immediately walked out again.

I've just set up a little webcam feed to put in the bottom right hand corner of the screen.
Not too sophisticated, but perhaps I'll one day be able to program a motion-sensor alarm for it.

That is so epically brilliant
I'm considering a way to do something similar.

Realistically, though, I'll just be too lazy.

Fucking brilliant!

dark uses
I was on jury service a while back and there was some old git who'd been banging his daughters in the loft, even when others were in the house, bet he'd have loved that system. Shame he went down for life!
