I'm brainstorming for my next electronic project to tackle. I build all kinds of circuit stuff for myself and it's a bunch 'o fun. I also design/build goofy industrial stuff for my job but that isn't so fun and exciting. But I'd like to make something that other hobby guys like y'all would like to use also, not a necessarily a complete project, but a sub-assembly that anyone can use for a bigger project.
Unfortunately I am seized with indecision. So maybe you can help me decide. Of course I'll share whatever design ideas I get working with all of you. Here is the short list of what I am considering, so a vote for any of these ideas would be most appreciated.
1. Lithium Battery Charger - will safely manage recharging of those small, light batteries for portable projects.
2. RGB LED system - multiple color LED array & driver for indicator and/or eye-candy design projects.
3. mono LED system - single color (white or other) array & driver for illumination purposes.
4. High-current driver(s) - board for controlling DC or stepper motors & solenoids.
5. Basic control panel - switches, pots & LEDs to interface between circuitry and humans.
6. Smart control panel - interface, uses logic to scan switches, LEDs, etc and connects to a computer (Arduino etc.) using UART, I2C or SPI.
7. Synthesizer circuits - using analog knobs & switches to generate audio sounds, or possibly controlled by computer (Arduino etc.)
8. Linear power supply - with multiple adjustable, protected and configurable outputs.
9. Touch panel board - a control panel that senses touch without switches.
10. DMX controller - interfaces to the commercial DMX-512 network to control lighting from a computer (Arduino etc.)
11. Audio mixing circuit - possibly digitally controlled.
Of course, if you have any other really good thoughts on what you'd like to see me work on, please describe it - it might just be an awesome idea that I would love to take on!
I allowed for up to three selections for those of you who are very enthusiastic.
