- Nic Collins shows you how to build your first circuit from scratch: the venerable 74C14 oscillator. From the DVD in "Handmade Electronic Music -- The Art of Hardware Hacking" (Routledge 2009).
wow, that's simpler than setting up a timer chip! thanks, totally going to use this in my synth.
Super clear explanations. On behalf of all noobs, thank you kindly. Cheers!
74C14. Other numbers: 4584, 40106. Try Jameco, Digikey, Mouser.
Thanks for the amazing video!!! I've got all the other components but was wondering where you could get the chip from? Thanks
Also what size potentiometer did you have
you can order it from ebay or buy ir directly from your local RadioShack
I have been reading the data sheet of the chip used, it says that it only uses 6v max of power should be used with the 74c14, but a 9v battery is used here, I have used the same and have it working; it's not even warm to the touch. I am curious as to why the battery is not frying the chip? Is it stable?
how to make a wing flapper with the oscilator ,using mini solonoids.
Is it okay to use a film capacitor?
Cat in a Hat . Yes im guessing so . Thou you wnt get film caps in a big size . Biggest ive seen is 474 aka 0.47uf.
Do you sell kits?
+Travis Borden : No, the fun is in the experimentation on the breadboard.
Mine never works! Don't know what I'm doing wrong, I have a different op amp so I'm relating what's said to this chip (the TI LM324N) but not having any luck. Could somebody please help me
Lewis Dolan An OpAmp (like the 324) won't work in this configuration. All chips may look alike, but they're different inside. You need a CMOS Hex Schmitt Trigger: 74C14, 40106 or 4584.
Thank you for the quick reply, I understand they function differently. Will have to experiment to get it to work
Lewis Dolan If you get the right chip it should boot right up whistling, shouldn't take any experimenting to get it working.
I have made this and it is working but the output from the speaker is extremely quiet, anyone any idea why?
tried it on my two amps, through the half watt it was just audible, through my 40 watt it was still very quiet even with the volume maxed out.
You need to send the signal to an amplifier. It will not drive a speaker directly
Note: under some circumstances, a polarized/ electrolytic capacitor CAN explode in flames and smoke, launching small pieces of itself.
ALWAYS double check your capacitor, diodes, voltage inputs, etc. for correct polarity.
i like to live dangerously but i lost my best guinea pig to a polarized capacitor and donald trump is doing nothing to help me.
i am new to this. can someone please provide a component list. for example the capacitor is a .1 microf but at my local electronics store there are. CD104 .1uf 50V Ceramic Disc Capacitor, CM104 .1uf 50V Ceramic Monolithic Radial Cap, CD104 Ceramic Disc Capacitor .1uf 50V, etc... there are also multiple types of photo resistors :) thanks for any guidance.
74C14 can run up to 15 volts, so I don't know where you found 6v as absolute maximum (maybe it's in the "recommended voltage" column of the spec sheet.) 74HC14 or 74LS14 use 5 volts, stay away from them.
Yep, I'm running the wrong ones, better swap them out. I'd much rather just use one battery. Thanks for the heads up, and also all the clear tutorials!
with 74hc14 and 74LS14 as they use 5 Volts, cain I use them with the same conections in the video with a 9V battery?
Why don't you show the amplifier on the right? What kind of amplifier or speakers needs this project? What kind of connections needs the clips to the amplifier? Thank you.
Rubber Flowers Sounds it’s just a small Radio Shack-type $12. amplifier. Check amazon for ‘small battery audio amplifier’ and you should be able to find something similar.
Also, if you have an old radio or boom box with an audio in jack, you can use that to amplify your sound signals.
His voice reminds me of tom hanks, its so awesome. I am learning how to do this project, and his voice makes it awesome. :D
No, I've never tried to integrate enough modules to call the result a complete synth, but the book includes a nice range of designs that could be combined in a synth-like fashion. I don't know of a single book that steps you thru a full synth, but there are lots of diagrams and kits out on the web.
OMG Radio Shack Breadboard... They were the best quality Made in Taiwan..
Hello, I'm really new to circuit bending. This is my bread board so far (See link below to screenshot) but mine looks a bit different. I've got to the part where I need to connect my capacitor but my busses are along the tops and bottoms instead of left and right. Have I got the wrong type of bread board, or is there a way around this?

Thanks in advance.

Three weeks too late, at any rate.
Your board should work if you sort the logic of what pins, on your specific board, are connected. The _location_ of the buss won't have any effect on your circuit. Think of the buss or rail as a location to hook to ground (blue) and a place to get supply voltage (red). On your bread board, the pins next to the red line(s) are most likely connected. Red is for (+). The pins next to the blue line are for (-). You have a black wire connected to your red (+) rail. Move it over to the left on the blue rail. That's assuming your black wire is hooked to negative. ( I'll bet your battery got hot.)
EDIT:
Oops, it looks like your red rails are separated into V1, V2, V3, V4. You can jumper them as you choose...
Harry Bolland No they should be fine , please take my advice thou on this if you like . Keep your plus voltage at one extreme and the minus voltage or your ground to the end. In other words if you look at the Ad 01 board Red V3 and V4 i would make the +v bus and the black bus next to v1 and v2 the minus voltage or ground. The reason for this is that i found i was getting a crossover and short circuit when i used the opoosite power rails too close together. I built a 3vco synth prototype on these boards , check out my channel if you have a mo.
If I could I'd be rich.
best demo ever...too bad all my radio shacks are gone..
there are still ebays
If I add more circuits, will I need to power each one individually? I built this circuit with the parts you suggested. Now I want to add more to the same chip.
You can power several CMOS chips off of 1 battery.
@@siliconluthier can't seem to figure out how to build more circuits off the same chip. That is doable right?
If I can, I can't hear them
@@Vice.K Yes, you can build 6 on 1 chip and mix them with resistors or diodes. The book explains how to do this.
Hey Silconluthier Please Create a play list for these making project and your other vidoes so it is easy for us to search the videos faster
Im very new at this but also very curious... Can you make some kinda of switch between different caps with different uF values that will make it able to change the frequency range of the oscillator? Like you want to make a bass so you use a cap which is more accurate at lower frequencies and when you want to use a more treble sounding "instrument" you choose a cap which can aid with that? And this all just by using a potmeter to change the overal frequency in the full range?
Yes,everything you said is correct. The switches are a good idea
Wow, this is seriously cool. Always wondered how this was done. Did you manage to build a complete synth? Any book recommendations aside from the one you posted or is that the best?
Thanks
awesome video thanks so much .....
please keep up you are the best .....
can u help me build a emp jammer?
Hopefully someone can help me, I've tried making this and it works fine for a blink led but my results are way off for audio. I'm getting all sorts of what seems like ground issues and I'm not getting any clear square wave.
I used the same components as in this video. I've obviously missed something. Again, any help would really be appreciated.
Hard to debug remotely, but check that you have no connection between the blinky circuit and the audio lines except for light. Some photocells have wider (better) dynamic range than others. The book walks you thru this project with pictures. Good luck.
Thank you a lot for this videos.
Awesome video!
Can i put the speaker dierectly to the oscillator without amplifier
No, you need a amplifier of some sort. The oscillator can drive a piezo disc directly, but it will be very quiet.
When i connect a 0.25w speaker it doesn't make any sound :( I have to use an amp like you?
You need an amp, cmos oscillator is low current, can't power a speaker directly.
thank you!
What is the cost for all these? Thanks in advance! :)
Depends where you buy them. But very cheap stuff.
Thanks for the quick response!
