Sarah Michelle: The 4 diodes are a curious thing; maybe their purpose is simply to drop the voltage by about a volt.
Sarah Michelle: That is sweet! And I love the little oscilloscope lcd. Nice they don't 'force' you to buy their kit by withholding the schematic and parts list. Seems to work just fine. Thanks for sharing.
Moiz Azeem: Are you getting 50% Duty Cycle on output?
james: How do you test the kit 23 with a multitmeter ive just finished soldering it.
Abram Harrison: I like that enclosure, where is it from?
Yash Desai: how did you made oscilloscope
Joseph Johnson: Do you still have the schematic for this? It is no longer available from Circuit Specialists.
Ramses Faradis: Gran circuito.
furulevi: this goes to 7000 Hz only?
Riskteven: I want to feed through a transformer to output an effective value of 230 Volts AC but with a variable frequency. I plan to upload something very fun on Youtube but of course a sine generator is still what I need. How to do?
smokescreen36: could anyone help guide too a mini audio spot light
Richard Wolfe: Simply cool.
Helge Sverre Hessevik Liseth: If you connect that to a speaker.... would it make sounds?
Zach Sylvester: battery almost expired
Sophie333C: Hi, built this function generator on breadboard, I managed to get 7.6kHz output. The waveforms are ok at low frequencies, but not too good as you go up the frequency range!
Octavian Sulean: Could you use a different op amp to have a bigger frequency? Could you tell me if this is posible? to have a frequency range greater than 7000Hz (e.x could it be modified to reach 20MHz) with an quad op-amp ic?
Rui Santos: thanks i will try this circuit soon, thanks for the reply!
Good luck with your projects
electronhacks: Coax would be better but a regular wire would work.
Rui Santos: For the output waves did you use which type of wires?
or just normal wires?
if you want your led blinking you can add to the circuit a 555 IC and it will easily blink the led... i hope it helps you
electronhacks: It is easy for you to do this type of research, do a search for the IC's name and "Datasheet" (You will need this if you plan to use the IC anyway). It looks like the pin-out is the same, the IC's are similar so since we are making a fairly crude device chances are you can safely substitute the IC's. That however does not mean you will not need to do some experimentation and possibly modify the circuit.
