Hi: Has anyone read anything similar to http://www.guardian.co.uk/science/blog/2009/jul/24/bacteria-computer ?? That article talks about a computer chip that is made out of bacterial cells. Will be feasible in the next 5 to 10 years to make an OPL3 chip out of bacteria? Bacteria are my favorite forms of life. OPL3 is my favorite MIDI synth. So I'm curious about the possibility of an OPL3 made of bacteria. Thanks a bunch, Green Xenon

Excellent, I guess this is the closest to what I'm looking for. How would I build an OPL3 using a breadboard and discrete parts only [no chips, and hopefully no PCBs]? Also, what maths would I need to know in order to build it?

Why use the toilet? Why not a sink? Silicon is a semiconductor. Would it be possible to use open air as a semiconductor -- with the distance of spaces between the coppers determining whether the amperage is a '1' [higher] or a '0' [lower]? These "spaces" would be gaps consisting of nothing other than air. I'd imagine the electric current would have to be an overall very high-voltage but low-amperage -- similar to electricity outputted by in stun-guns. Given the same voltage, a wider 'space' would result in a lower amperage while a closer one would result in a higher amperage.

There is no integrated circuit. The circuit is discrete.

What about my customized OPL3 makes it impossible? Couldn't I build the entire chip out of copper?

Hi: I'm thinking of building my own version of the OPL3 FM synth chip without the use of frail devices. I would like this OPL3 replica to fit all the following characteristics: 1. Does not need any soldering to build 2. Is easy to physically carry around 3. Can withstand temperatures extreme enough to destroy the original OPL3 chip 4. Can withstand physical stress [such as from accidental falls] without experiencing any damage 5. Does not contain or require the use of any hazardous material [such as UV light and chemicals] for construction or operation 6. Can withstand static electricity without being damaged to any extent 7. Can withstand -- but does not use -- amperages high-enough to instantly destroy the original OPL3 chip ithout being damaged to any extent 8. Can withstand -- but does not use -- voltages high-enough to instantly destroy the original OPL3 chip without being damaged to any extent 9. Can withstand -- but does not use -- wattages high-enough to instantly destroy the original OPL3 chip ithout being damaged to any extent 10. Can withstand square-waves [e.g. clipped waveforms], spike-waves, triangle-waves, and other sharp-edged signals intense enough to immediately obliterate the original OPL3 chip without being damaged to any extent 11. Can be submerged in water without being damaged to any extent [even while running] 12. Can withstand short-circuits without being damaged to any extent 13. Is small enough that it can be easily washed in the average household bathroom sink 14. Can be vigorously cleaned with water and dried with any towel without experiencing any damage. 15. Can be disassembled and reassembled without being damaged. This is in case #13 is not possible. If #13 cannot happen, then I can wash and dry each component after disassembly and then reassemble the OPL3 after all the parts are clean and dry. Is is possible for me to build my version of OPL3 device given the state of today technology? If not, what is the closest I can get? Thanks, Green Xenon
