Crafting electronic devices as a hobby!

Any ideas?

Making stuff to use for electronics is popular. Power supplies, function generators, frequency counters and the like are all a) quite expensive to buy and b) fundamentally quite simple. Decent enough ones can be made by the hobbyist.

I wouldn't expect to save any money by producing useful everyday items because industry pretty well has that market covered. You can still make TV remote controls, alarm clocks, stereo amplifiers, burglar alarms and so on if you like, but don't expect to beat the cost of the product in the shops.

If you're already into computers then robotics provides ample opportunity for electronics, though the results don't usually qualify as useful.

Thanks a lot!

That was awesome!

Thanks

A bat detector? There are simple circuits which convert the ultrasonic searching calls to frequencies within human hearing range. Good fun, especially if you have kids, as they can often hear sounds above the adult range anyway!
