- There are several ICL8038 based Function Generator kits out there. This one is the best I could fine. In this video I'll review Assembly, A Device Overview, and Device Performance. For $8 this is one incredible deal for the electronics hobbyist!
I'm glad I found you. I just ordered one from EBay. Thanks for your knowledge! Cheers from Australia 🙂
The user manual with the assembly instructions are full of errors. The UA-cam video "Electronic Project (4) Signal Generator, Making a Low Cost Generator" contains the correct manual and instructions at 5:51 (that is 5 minutes 51 seconds into the video). You may have to magnify the video to understand the instructions.
2:50 I built one of these yesterday. One thing I noticed is that polarity is not marked on the caps described as tantalum on the build sheet. They certainly do look like tants.
There is no orientation on the silk screen print either.
The capacitors show as non polarised caps on my component tester.
Usually there is a "+" mark on the positive lead.
@@EdHumble Yes, exactly, but in this case, there is no marking on the capacitors, and no marking on the silk screen print. The assembly sheet says "Regardless of the polarity".
I'm wondering it these even are tants, although they certainly look like them.
@@TonyLing They sure look like ceramics to me
Can the out voltages change the amount within a certain range?
Thank you! My instructions were faded too. Luckily, I found your video while looking for instructions. I wasn't aware of the errors and gotcha's. Thanks!
is it possible to use it for audio? synthesizer?
Generating audio frequencies with a pretty darn good sine wave, is not a problem. You’ll just need a frequency counter to know what they are.
Does it make sound??
If you add an amp and speaker....
you could have made the video better.
