1. Oh boy, I was looking for part one for the xtal/freq tester, but this will work. I did these ones, nobody to share the experiance with, but watching these I find entertaining. You appeare competent, so the short commings are the usual poor engineering put into the kits, and That makes it interesting. Like watching someone taking a bad joke. Good show, good times.

2. Gave up on the signal generator.

3. is this not your main channel?

4. Has anyone figured out how to get rid of the noise on the signal? It seems that all these kits have a bit of noise. I am thinking that might go away if the inductor was shielded?

5. Did you ever build the function signal generator kit?

6. Whoopy …i got a package……i am in heaven. NUTCASE !!

7. So pleased i found your channel i got the oscilloscope all surface mounts pre soldered cost 17 squids.just finnished assembly and works great. Cheers mate.nice recommend, keep up the good work

8. Hi Julian!
   Do you think this project is possible for a hobbyist that don't have an oscilloscope for testing?

9. I was going to suggest an atx supply, but perhaps two isolated 12v and a 5v generic switchmode deadly china power supply combo would work. Or a massive bank of eneloops and a 7912, 7812, and 7805 regulators in an ol' bodgery-at-its-finest setup.

10. on the scope: please test the input voltage range on wich it can work. i already read 12v is too much (transistor will get very hot) but will it work on 8.4v and below? (i am hinting on 2 lipo cells to make it portable)

11. I didn't know the ATmega was even produced in a through hole package, thought it was only surface mount

12. Hi. I've got myself last year a DDS generator but that one actually runs from 7-12V and has split supply generator on board but it generates some ripple on the output so I'm not very satisfied with it's performance. Also, I wanted to actually get an oscilloscope kit also but I just cannot cope with having only 4-5 buttons interface so I rather get an old CRT very basic scope that would the job much more better. So, I'm still hunting for a cheap USB computer oscilloscope. Also, please do a review on those small white usb oscilloscopes that cost about 20$ and have a bandwidth of about 5Khz. Cheers 🙂

13. You can build 3 voltages power supply with transformer, diodebridge and 7805

14. OTAs are high impedance output because their output is a current source.

15. Julian, did I hear you mention you have another channel? One dedicated to electronics? Mind sharing that channel with us?
