It’s projects like this that make me all warm and fuzzy on the inside.
José Pino describes in detail how to build a loudspeaker from :
- 1 Magnet
- 1 Business card (Please make sure it’s expired or cancelled first)
- Wire 32 or 34 AWG
- Paper bond
- Ballpoint pen
- Lego bricks or wood.
This reminds me of an old dream I had of a DIY, steampunk, radio project. I think this guy just inspired me to take it up again.
The link and image shown are actually for his original speaker design. The Hi-Fi speaker is actually a different page.
