Anyways, I made a DIY wavemaker using the readily available electronic timer kits (the ones for educational purposes).  It cost about $10.  Since it is already a 555 timer circuit, all I needed to do is change the potentiometer in it, add a plug, a cheap 12V power supply, and enclosure.  The original pots made the ON/OFF cycle to be roughly at 5-10 seconds.  Changing its value enabled the circuit to cycle at about 3-5 min.  Total cost for the first one is about $20.  Making two would probably cost about $30 total, since a larger enclosure cost about the same and will be able to house two units and the 12V power supply is shared.</div> <div> The circuit had been running for 3 years 24/7.  So I would say its pretty reliable.</div> <bR> <div> There will be photos soon with specs on the pots that were used.  Hopufully I'll get to it by next week (Aug 16, 2004)</div> <bR> </td> </tr></table></body>
