If you ’re both cheap and savour losing your oculus thanks to a vanish cadmium shard , take a look at this home - made USB Cooler . All you have to do is take an old CD , cut it up like a sports fan , melt it down so you’re able to writhe the shards , bond a cork in the middle , plume up a few wire to a niggling motor , hook that up to a USB port , and you ’re right to go . If you ’re really lucky , nothing will happen and you ’ll get a squeamish snap . If you ’re unlucky , however , say auf wiedersehen to your corneas .
