Great video Jane. The younger me always wanted to get into electronics but i never had the chance. It's only been in the last few year that I've actually said f it. I want to know about circuits and devices. TH-cam is an incredible tool for learning in your later years. Also these components are so cheap now. Not like 35 years ago. Keep up your channel. I'm a new subscriber.
In mid 90s I built my lab signal generator, with two of these chips. One was the signal generator and the other I used as sweep/AF signal to modulate the main oscillator. It worked so well that when I find this kit online, I got two of them, to remake that generator that I did many time ago. Maybe you know, but the actual IC seems to be a clone that is not so good as the original Exar part. But, I changed the schematic a bit and I improved it enough to use it. The main improvement (that add to stability) is to power it from a symetrical power source; I made mine with an transformer and a pair of 7805+7905 ICs. The stability is very good, the waveform is quite clean (sinewave) and the max frequency is around 4.1MHz (without capacitor).
Good kit for what it is, good for someone starting out, and lets face it we all started some where.,hope this help some, when I solder components to a board I start right in the middle and work my way to the edges, that way you don't trap yourself, with tricky soldering situation's
This is turning into a cracking little channel - well done and nice work JJ. You need to get one of those Duratool PCB holders - I got one and they are great for soldering kits.
Thank you, glad you are enjoying the videos. We must be on the same wavelength with the PCB holder, I've just picked one up from Amazon to use in the next video!
Real deal old school test gear! I like it how you use an analog scope. I just love these oldies too much, they have the touchyfeeliness of controls that modern digital gear no longer has. Plus you don't have to RTFM for every new model and stagger your way through the menus to get the simplest stuff done.
Couldn't agree more! The analog gear just looks and feels so much better! No matter how many bits of modern gear I test, I still always rely on my tried & trusted gear for the best results!
LOL! I know the feeling. We have two o scopes at work and I always fumble with menus when switching between them. Add my personal sope, and its 3 different menu trees. I hope they never do away with rotary volts/div and time base selector knobs on the benchtop machines.
I picked up one of those a few years back, could never get a good sine wave out of it. Had a nasty notch in it, what I'd expect with a bad output transistor in the IC. Still got the thing somewhere in a box of parts
That's neat. I'm trying (again) to learn soldering, so that could be a useful little kit to put together. May I ask what you use it for? I imagine hooking it up to a speaker you'd get square, sine, triangle wave tones. Or is it pretty much just for learning to use an oscilloscope?
Fantastic! Yes, it's a nice easy kit to start with and it is a good way of learning to use an oscilloscope. Yes you are right, you can use it to get the tones out of a speaker. I'm going to be using it in some repairs on amplifier modules for some active speakers with a test speaker to help me see where the problems are. I used it on an Ashdown guitar amp recently to put a signal in and find the speaker was fine, it was a power supply problem on the main board in the end but at least with the tone I knew the speaker was ok and it was worth repairing.
Thanks for watching! I'll be using the signal generator in some upcoming repairs on amplifier modules. Putting some noise or a signal through a circuit can help point me to where the problem is.

Good on you Jane, Just subscribed. Its so refreshing to see a girl doing electronics.
Thank you, that's awesome to hear, I'm enjoying making the videos and got some great projects in mind for future videos. Thanks for subscribing! :)
Nice little kit. I can see this as being useful for anyone just learning to use an oscilloscope.
Definitely!

Nice vid! Subbed and looking forward to your next videos!
Awesome, thank you! :)
It's always an interesting challenge to figure out some of these kits and their minimal (and often non-existant) documentation.
Absolutely! All adds to the fun! :)

@@JazzTechUK Sweet! Wish I already had your knowledge and skills. Looking forward to seeing more on your channel ✌
Good luck with your channel. If need help or suggestions would be glad to contribute. 👍♥
interesting but i have no clue what a signal generator is for , sorry jazzy , but interesting to watch👍
Thanks for watching! I'll be using the signal generator in some upcoming repairs on amplifier modules. Putting some noise or a signal through a circuit can help point me to where the problem is.
Raise your hand if you hate blue resistors ....!
Lol.
Tolerance Bro 😂
