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.

Batteries killed the radio star
Back in the days or old I had one of those big chunky cassette walkmans, however I grew tired of the weedy AA size batteries dying after only a couple of hours, hardly enough tape time to get through the average school day.

I then discovered in the garage Dad had a stash of much beefier looking D cell batteries. So I set about modifying my walkman with some serious battery life. I wired up a dozen of the batteries in 6 parallel circuits of 2 batteries. OK so the battery pack was twice the size of the walkman but it would be great!

It played about 22 hours of music before the wiring inside the walkman melted.

I now have a strange
desire to try this out for myself. Have a click!

I made do with 4 'D' cells on mine (2x2)
and it worked fine for several years. I never bothered working out how long it lasted, but as there was no car stereo in the then-evilsteviemobile my non-walkman having a speaker on the tape-lid meant it had extended use up and down the M6.

I destroyed a ghetto blaster
with a car battery.

Cost about a fiver (in 1987) to put in normal batteries and worked for about 8 hours so it had to be done.
