These function generators are all over the internet and are dead cheap at under £20 inc postage, but are they any use? well I bought one and this is how I got on with it.
If you like to support me, why not buy some music matthewnorth.bandcamp.com

Thanks for the review
Matthew I've been watching your channel a lot over the last few months and you have inspired me to start doing music electronics and I am going to build one of those Harley Benton guitars. Just like to know where you got those plastic socket tools from...I cant find them on Ebay....
There called rocket sockets I first saw them on Uncle Doug's CZcams channel a few years ago.

At 9:28 it looks as though your scope has AC coupling selected, which will block any DC offset.
Well spotted thank you it's been a long while since I used a scope as you can tell !
These are not designed to have a battery at all. Yours is a heck of a lot better made than the one I got. I had to replace the fake OP-amps on the output and re-mount the display.
That sounds rubbish. I got this from a UK seller no idea if that had a baring on the situation or not ?
Nice demo. Sorry if I missed it but what is the minimum frequency adjustment increment?
1hz
I see you have "the Persuader" just above the turntable there 😉
Do you think this can be modded for 1V\Oct?
Also, is it tuned, or does it need calibration out of the box?
Well it appears to be pretty accurate looking at the scope. I did think could it be an oscillator bearing in mind it's a micro controller I'm sure someone with coding skills could rewrite the code to be controlled from midi and have a gate our. But then again you may as well just get one of these micro controllers Ans download a synth programme for it. Though it could be fun if you can incorporate them display And with new code a din socket And opto coupler turn this isn't a synth!
it is nOt "high frequency", under 3MHz is "LF" or "Low Frequency". HF is 3-30MHz. Men like you need to man up and liberate your little island, or if you can never do that and will never afford a proper function generator, then just get a microcontroller or arduino and an SI5351 and a few cheap component and make an HF/VHF...etc generator
Well that's me told then . . .
@@MatthewNorthMusic you're the best man, i am joking with you. thanks for the effort and this makes a good budget tool for audio application to save the time of putting one together
