Hi Paul, I wanted to thankful for the great videos about electronics. I've always been interested ,but I was afraid of the math .I'm a disabled vet , I was in the navy to,a mm and a shellback.Anyway I've started to gather the equipment and the parts from banggood . I'm awaiting on my first order to arrive any day,with the things u have suggested to get to set up shop. I'll be watching Paul thanks again.
Just got mine out of the mailbox. This one is a full kit version, all the parts in a sealed anti-static bag in a small package that easily fit into my tiny mailbox. I also got the power connector as well and it curiously came in an Amazon box the size that would hold a pair of boots! Still waiting for the frequency counter to get here, I plan to merge to two together in one unit for ease of use.
Hi mate, just got the diy one, but rather than soldering it, I have taken the schematic and am trying to assemble it on my breadboard. I am a beginner and hope to learn something from this experiment :-) it has been useful watching your video as I wasn’t sure what the 5 pins jumper was for (and now i have to find a workaround as I can’t stick it on the breadboard lol) thanks for your interesting videos!
Feed that square wave via a Schmitt trigger. It actually comes from the Sync Out of the XR-2206 IC and not the Wave (Sin/Tri) outputs. Use as a sync pulse for your scope and/or as a TTL signal (from the Schmitt trigger IC of course)
Don't mean to be critical, but showing you adjusting the knobs and the result on the scope would be helpful. I have the kit and another small kit/scope that I am trying to hook up. Any result will be amazing to me. Thanks for your video. Thumbs up!
Hello, great video 😄 I'm a beginner and I have a question : I would like to make a diode bridge rectifier and I need an alternative voltage at the input. Can this device be used as an alternative power supply to generate the alternative voltage I need in input ? Thank you in advance for your precious support. Cordially.
I got the KKmoon version and it was junk! 😂 I bought it back in November of 2018 and one month later used it to acquire some desoldering skills. I salvaged virtually all the parts but I am currently in the process of rebuilding this circuit using component values according to the XR-2206 data sheet. I have the 1st test circuit working (which is already a better circuit than the one provided) and want to add more functionality to it and hopefully get it soldered onto a new blank PCB board. Cheers!
@learnelectronics - Thank you, again, for a clear and helpful video sir! I have one of these kits waiting for me on my desk right now (it arrived with the Hantek yesterday!). I opted for the kit form in order to practice my soddering, having copied @BigClive’s tut and successfully soddered together a tiny Flashy LED kit last weekend... 👍🏻 🤪
On the kit board you need to cut the leads off as flush as possible so the screws that mount it will be long enough. I had to get longer screws for both the board and the case. The screw holes for the rear back of the case had to be opened up. Also,yes the amplitude control works backwards.
Hehe also faced that ended up that its the wrong way to assemble it. The screws only got thru the PCB and not thue the bottom of the case. The nuts are there to offset the PCB and the remaining threads to allocate the PCB not to move left or right . The top of the IC and the pot's holds it down.
Sorry to say but they are all the same design, components, just under different names. The components are indeed subpar. The tolerances are way too loose on the components specially the 2206 chip. Since they are kits, additional variants occur depending on where they got their components from. Which explains the wide variation of reviews from good to bad. Even if you get a horrible kit, it's still a great buy for $10! Because it can be fixed easily. People bitching about a $10 kit are insane. Just the 2206 chip purchased from a component distributor costs between $10 to $25! The kit is a new brainer. Most people are lucky and can get decent results with no modifications. Any issue can be easily fixed and even if you get issues, you are still way ahead of the game. I recommend this kit under any name.
It's on sale for $3.99 shipped free at Banggood.com right now. Most of the 2206 chips are counterfeit which you can tell when you run them near the max specs but still work.
You should find a circuit diagram for this function generator - the same circuit is used by many suppliers. The 1-10 Hz range uses a 10 μF electrolytic capacitor; the sum of the capacitances for all the other ranges is less than 2 μF. So the expected frequency range would be roughly 0.8 ‒ 8 Hz.
@@Cargoshots buddy I wouldn’t do that again...you could easily blow your speakers..but you can use it as a modulation source. I keep it in my workbench when I need a quick pulse wave to use as a trigger or a sine wave for any purpose, like modulating my vactrols 😉
@@Cargoshots i hi i it is about the frequency. I am still learning, I am afraid I can’t give you a more meaningful answer and am reporting what I heard. I could be wrong but you know...just in case..I would keep using crap speakers for experiments 😅

Another fine electronics vid. And you mentioned Skynyrd, and Zeppelin. A double whammy of goodness.

Plus he has excellent taste in music.

Hurry and order there's only 14 left! Good video again, thanks.

@@Allan-mf1he yeah saw that on another video.
hello. is it possible to obtain a sinusoidal frequency value of 7.83, with an amplitude of 3v and be stable?
Didn’t you get the four small stand-off screws for each corner the board inside the case?😉🇬🇧
got one from aliexpress, kit version because I also like to solder.
But I had to file and adjust the acrylic case, wasnt fitting properly the knobs...
TheKetsa my case snapped in place...it needed a little persuasion
Nice looking unit...
Awesome!

You could plug this into an amplifier and hear it as well. 🙂
Ya this is coming in for me in a few days
Sir what will be the output if I connect jumper to all the possible frequency range simultaneously?what will be the frequency range of the output?
You should find a circuit diagram for this function generator - the same circuit is used by many suppliers. The 1-10 Hz range uses a 10 μF electrolytic capacitor; the sum of the capacitances for all the other ranges is less than 2 μF. So the expected frequency range would be roughly 0.8 ‒ 8 Hz.
You will add the caps in parallel so guess the frequency would be lower than 1Hz.
What are these used for?
Could you use this to make a synth?
I had the same thought. I guess you can fit it in an Eurorack module. It takes 12 volts..I could probably try
@@Cargoshots buddy I wouldn’t do that again...you could easily blow your speakers..but you can use it as a modulation source. I keep it in my workbench when I need a quick pulse wave to use as a trigger or a sine wave for any purpose, like modulating my vactrols 😉
@@Cargoshots i have heard around that they chose component’s values without considering the datasheet of the IC and apparently they made a mess lol
@@Cargoshots i hi i it is about the frequency. I am still learning, I am afraid I can’t give you a more meaningful answer and am reporting what I heard. I could be wrong but you know...just in case..I would keep using crap speakers for experiments 😅
Could something like this be used to transmit a signal for a DIY metal detector?
It is an oscillator
Has anyone tried running this off a 9V battery? What were the results?
i think i saw this exact same thing in a online store (not amazon or ebay btw)
ALTHDS yep, they are all over. Banggood sells them, gear best, tomtop. pretty cheap
learnelectronics i think imgonna buy one, got alot of projects to do in 30 ish days
ALTHDS go for it. they work well.
The sine wasn't a good one at all. Wish you showed a spectrum plot. Btw thanks.
Yea it will be all over the place. More harmonics than a church organ...
What power supply does this need ?
It requires +12, -12, +5, and Ground
I think learnelectronics was thinking of a different function generator - this XR2206-based kit needs 9-12 V DC.
Tested this it will start producing limited frequencies from 5.5V and up to 12 to be save.
9-12vdc
No drok equation lol
You are just a tester a critic !!! not an electronician !!!! go out ......you make a blah blah ..
Fake title as it's not a kit and too much yapping about unrelated garbage. Thumbs down.
