After experimenting and finalizing your design, you can transfer it to one of our Oscillator boards to make it more gig-worthy.

What you hear is the sound that came out of the synth with no editing. Now however you control the LED will control the high-frequency component of the timbre. It was easier to select with a scope but you want the first oscillator to be at a low frequency and the second one to be high, otherwise the first will gate off the second entirely. Release, no power and silence. Google to find loads of information on the subject. A couple of CMOS-based modules and some banana jacks will get you a looong way: Try using variable resistors and start monkeying with the rate of the first oscillator, then the frequency of the second… then both.


What is with the auto download on the vimeo vid next to the bottom? If you substituted an inverter without hysteresis, its output would sit at the single voltage threshold. When you release the button, the capacitor will provide enough charge to run the circuit for a little while, smoothing out the release of the note.

You can then use light to control the pitch by waving your hands around, which is kinda cool. Thanks a ton for posting that up. If you add hysteresis into the mix, you get an oscillator. Hysteresis is just Greek for: Conclusion, and Next Week: First, they make spikey demands on the power supply as the internal transistors are switching.

You are commenting using your WordPress. That is a great link-thanks: Otherwise you can lean on the LDRs again, and make yourself a light-dependent volume control by adding an LDR to the voltage divider that I suggested above to get the signal down to line levels. I finally had the time to play with those a bit: All 3 oscillators signals are now mixed together, out to the amp. SO those are some basics: A larger resistance limits the current, slowing the cycle yef40106.


Any way that you can put a variable resistance in this circuit is fair ehf40106. Or, hold the two resistor leads in your fingers and squeeze to change your skin resistance. Learn how your comment data is processed. Hex just means that there are six inverters in the same chip. Oh, this is just the beginning! Remember that the input sees the capacitor charging and discharging between the two threshold levels. This site uses Akismet to reduce spam.

Data sheets also often have sample schematics that can help get you started using a new chip. If you get anything good, record it and link to it in the comments section.

I did this, and told Firefox to forget hackaday. For my wife, about three. You can also change datashet capacitor value… swap in some different ones and see what happens.
