Thanks for your feedback! Indeed, kids could learn the real pyrography by using this 'coffe-graphy', the hand movements should be pretty similar to those used with an engraver. It would be useful to fix the small wood stick in a pen-like holder to make the process of drawing more comfortable.

I would humbly suggest that this device has a certain commercial potential, not just as a gadget, but also as a useful appliance ( 'sbrown' comment shows this kind of use).

That's an interesting combination of new and old technologies; a union that makes force.

That's a great example of thinking outside the box.

Why necessarily 'kitsch' ? Had the parrot been painted as a real one, then it would have been a bit kitschy; now it has taste

My point was to make a device that allow you to create colour music manually, it's nothing to do with microcontrollers

Indeed, when you use colour filters, you avoid problems to find LEDs of necessary colours; it's especially important when you make a 12 coloured projector, as it was in the original design

'Wodden' - did you mean 'wooden' (made of wood)?

'...we could use Large step up converter to use the output from the receiver coil to light up CFC bulbs!' You could not! The power received by your receiver just can not be greater that the power transmitted by the transmitter. What's the power supplied by an 1.5 v battery?

You might be interested to replace the 'clap' feature with the 'blow out' feature. Imagine 2 contacts made of copper foil that are placed inside the candle's body face to a hole. You blow into the hole, the contacts close, which provokes a 'reset' impulse, then the contacts return to their initial position because of elasticity. The candle goes OFF, you'll have to turn it ON again with the switch.

Thanks!

This project makes me wonder: is there anything that CAN NOT be 3D printed?

That's awesome indeed, not just as an enticing title for an article

the baby who is able to detach this sort of buttons is old enough to keep his/her on. He/she already knows that not wearing socks is frowned upon in the society.

This idea could be commercialized, I think, many extreme tourists would appreciate the kit.
