I took on a new DIY today to get some nice wave action without breaking the bank. This is a nice segway from my diy controller I run, much simpler though if anyone is interested!
What you will need:
1 x OMRON Solid State Relay (5-24 volts DC / 24-240 volts AC @ 25amps) ebay, $6.99
1 x 10uF 16 volt DC capacitor
1 x 500k potentiometer
1 x 1k 1/2 watt resistor
1 x 555 ic timer
1 x DC power supply, 5 - 15 volts DC
various wires
various resistors are good too, you can use them to really dial in different frequencies.
ie. I found my tank formed a nice set of waves around a 3/4 second cycle. I was able to nail this down with an extra 100k resistor and a smaller 10k potentiometer
Wiring is as follows, increasing the resistance between pins 7 & 6 will slow down the blinking, I'll try to post a video of it in action soon, enjoy!
