Theye sell loads of different electronics kits. Check out the robot voice effects generator in the Sounds Generator section. Thats got to be worth £10 of anyones money
My advice is don't bother. I just received 3 kits from them on of which had a dead gate chip and another had a couple of dead transistors. When i actually got it working it was just rubbish.
I haven't tried the last one yet but i'm not holding out much hope.
All these kits seem to be sourced from Russia, at least all the text on the back is in cyrillic script. Any static sensitive chips are just wrapped up in aluminium foil
On a positive note i got the 'robot voice' ring modulator working fine and its pretty good.
hi i got the spring reverb driver and its dead iam no very good a trouble shooting so mayby u can ake the risk but ive lost my money on it but i did make the voice changer abd pre amp kits no trouble at all they work fine
