A channel of exploration. Many of the videos are about building electronic kits. Many of them are inexpensive kits from Amazon and eBay, I put them together and describe the process, including tips and techniques and potential problem areas. I also evaluate how appropriate they may be for beginning builders. I also build many Eurorack (euro rack) music modules. By the way, I purchase all of these kits myself at retail prices.
I also occasionally disassemble things to see how they work or how well they're build.
And of course, other miscellaneous videos as the mood strikes me. NOTE: I am not an electronics expert, I'm a guy who has built electronics for nearly 60 years, but if you're looking for in-depth circuit analysis or design, I'm not that guy, there are many good channels for that.

at 27:00 you placed that part wrong it should be flipped, I think that's a reason why it didn't work
You are correct. My fault entirely.
I just found this kit on sale at Thonk, and now I need to solder and assemble it. Thanks for filming your build!
@tofu_pilot this unit sounds FAN-TASTIC, I think you'll really like it when you're done. As I say in the description and in the vid, pay careful attention to the instructions for some parts placement (and ommision) you really want to get right.
It was fun to watch you build this kit. Sounds great. It looks like the knobs are too close together. What do you think? I would prefer a wider module with more space…
Thank you! And yeah, it's a little cramped, in my studio it's OK, but if I were performing live (which I haven't done in decades) it'd be a bit touchy when you're blending on the go.
What's the smallest speaker you can use with this kit? I'm trying to fit it into a 3d printed microphone see 🙂
It will drive a 4-8 ohm speaker, that’s really the only requirement. I found these tiny 8 ohm speakers on amazon, they might work for your project. www.amazon.com/Treedix-Full-Range-Advertising-JST-PH2-5mm-2-Electronic/dp/B0CJNB3CR2/ref=sr_1_7_sspa?crid=9RBBVPA303MN&dib=eyJ2IjoiMSJ9.CinbAm5fISVSxGvmbBI3gtxY3EdvIGALXIBCBn4dxnt9iGbDSwcFVE3tx3G3IHsutj9Lb5Ule2_zyyBvfT7aktjxisLFSrgrIsLpjJWhlHhH8jxfv_ikv6C-WY2pjqAtRdZKst5M9fYDCf6VnaAvZIAZcx999Bubt-01nnG1NX63y-6jHS-UktMVQBu5pbN1puJ3Yrifi9Cl96ac2X7SntFM3VaoHVONqYj3yHOzcmI.QVyIAwzZW3M86PAvWbJVdhs34Y4JH1_QHuA1tylPwQc&dib_tag=se&keywords=Small%2B8%2Bohm%2Bspeaker&qid=1721658080&sprefix=small%2B8%2Bohm%2Bspeaker%2Caps%2C163&sr=8-7-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9tdGY&th=1
@@CKHaun thank you! 😊
2:10 you made a boo boo. Just saying mate.
I did, didn't I? "Standard"? No idea what my brain was doing. But if we went through and found all the errors in my vids we'd have quite a list :).
I’m with you-I despise stand-up resistors.
Just don't design in failure points, folks, that's all I ask.
marty we are going back in time !
True enough. But now-a-days we have the choice between digital routing and these old-school patch cords, so it’s really the best of times.
When I disconnect the battery at the back, my new selected message is gone. Do you know how to save a message when I disconnect the battery?
I do not think there is any non-volatile RAM in this one. Power off and everything you’ve done vanishes.
Smoking that elite pipe like a distinguished gentleman 😅😊
At least it’s a good front for sophistication, innit?
I had lot of trouble with this one. To this day, it is still on a bag and I won't going all out again... Never understood where was the issue. I bought other kit from Beast Tek and more complex kit and those where fine. Maybe I will watch your video on my working stand and try to find what's wrong. Keep up the good work Mr. Haun !
Thank you! On this one, I’d check your diodes first. Easy to reverse them (I catch myself on that all the time) and since there are so many one might have gone backwards.
That's work you connect wrong sit IC that is the problem 😂
You are correct!
I’m planning on buying the parts to make a plasma vortex and all I need to know now is the name of each part so I can write it down.
There is no bill of materials for this kit. However, here’s an article from PopSci with all the parts you’d need. www.popsci.com/how-to-build-jacobs-ladder/
Thankyou for the video. 👍I built this one yesterday and was trying to calibrate it today. Had much the same experience. I wasn't sure what the objective was with calibration of the self-oscillation LOW FREQ but your video helped me a bit. I also had the same issue with the 10nF capacitor not fitting (17:55). I was forced to solder it to the underside of the board. My kit was missing the 300k resistor, so I put in the lowest value 330k I had (317k) (the 300k is not even in the BOM document!) I also had some extra resistors and figured they were spares too 🙂
I emailed with Feedback Modules and he’s going to clean the instructions up when he can. Thanks for watching!
thanks CK.... just a word that if you rest the ic socket on your finger while you solder the pin, there is a possibility of burning your finger, especially if the pins are those milled ones.
Oh yes, happens all the time. But I have burned my fingers *so many times* over the decades that I barely notice anymore. I should mention it, though, for those who aren't quite as foolish as me.
A rather clumsy presentation. You clearly didn't research the YIHUA 959D unit.
No I did not research anything. I buy stuff and mess with it. That's why it says 'C.K. tries' not 'C.K. reviews'. I don't do reviews, I grab things and see how useful to me they are right out of the box like, I dare say, a great many people. THa's my thing, if you want well researched and comprehensive reviews that ain't me.
If you were observant, you would have seen that after you put the nozzle back in the cradle, it started to decrease temperature as it cold off before shutting down and going into standby.
True enough.
maybe try recording with line-in....
I know, the speaker is a bit too far away. But that’s my setup right now.
I just bought one also and am not happy with it . Yours is used. Meter is suppose to come with a protective clear plastic film you peal off that's over the display. When I put my meter in manual, the display keeps saying it's discharging and I don't even have a capacitor connected. I don't know if that's normal or not, the directions don't say.
Mine says 0 mF without a cap connected. And yeah, it's not a great unit and my multimeters do a fine job at cap value sensing, which is all I really care about.
Yes it’s random number generator is not great lol
Yeah, probably some sequential loop starting with the same seed each time, a 2 line gen.
Yeah I made the mistake of not grounding the switch to the case and got some very erratic behavior
Erratic might be good with this one, better randomizing :)
Yup still lots of board game playing
I wish. Very few opportunities.
It's actually a major scale, not chromatic.
Is it? I didn't put it on the tuner so I was just 'earing' the tones, not surprised I was wrong.
Always love your videos, thank you for sharing ur work :)
Thank you! I enjoy doing them and sharing them!
Thanks for sharing, I've never heard of Mitch Electronics here in Australia, will be sure to check them out 👍
Thank you! I don't remember how I found them, but I'm glad I did, the web pages accompanying the kits are very useful.
can you review this YIHUA 948D basic version high frequency desoldering gun suck tin station vacuum desoldering station
Would you please post an Amazon or Alibaba listing so I can make sure I'm looking for the right one that you're interested in?
@@CKHaun YIHUA 948D basic version high frequency desoldering gun suck tin station vacuum desoldering station
i tried this,,,,,,, its so hard to remove solder on big relays
Take a look at this one (got it after the one you just looked at). This is excellent, and will pull the solder out of relay holes very well, I highly recommend it. C.K. tries a GREAT Yihua 929D-V desoldering tool kzread.info/dash/bejne/lZ6sr9WjeL2qZrA.html
@@CKHaun how much is this
US$39 on Amazon.
In case I forgets to mentioned it… thanks for the resistor time music🤣
Just wait until I finish the next one! That I laid the theme down for a year ago and still ain’t done :)
Hi CK, do you know where I can get a replacement seal for this please. It’s the blue seal under the chamber sealing the chamber to the nozzle part what’s the proper name for it?
Hm. It's not a standard o-ring, it's a molded piece of silicon, so no off-the-shelf replacement, probably only available through Yihua. I couldn't find it, might be best to post a question on the product page, they seem to be quick to respond.
@@CKHaun I had written an email to them no response yet
If they respond, please post here so we have a record of this for others!
Here's a tip for you. Put flux on the board, don't be stingy. Now grab your already used up solder wick and tin all your pads. The truck is to get it where you aren't seeing that curved bump of solder that would make it impossible to get your LEDs flat. Maybe just do one side/row until you get it down. If you get it just right you can do both sides though. Those LEDs are tiny, it does not take much solder. The 3 throughholes right in the middle of the board L-out GND R-out. Use 2 of the 3 there. It doesn't have a microphone so it has to have input to the "spectrum analyzer". The L and R out does not go to the speakers so it's probably line level. You only use the ground and L-out and L -out goes to M on the LED board. 5v you get from the throughhole on the 5v track under the header pin. It's not marked but the track is pretty big. You should be able to use the LED board with any audio output of the correct level. This is basically 2 separate devices stuck together. They really should mark that better. So if the Bluetooth board isn't working just hook the the LED board to something else. Either way unhook the LED board and the try the media player again, in case you did solder something wrong or there's something faulty on the board. One part of the thing must work right?all I really care about is the pretty lights $40 you got robbed. I paid 32 and now it's like 25 so I got robbed too damnit. I forgot I bought this kit, it's been sitting on a shelf. I'm glad I waited to do it because when I bought it I did not know that copper braid trick so it would have been hard to do. Now I'm deciding hot plate or hot air. I'll probably try both, for science of course. I'm crossing my fingers that mine will work
Lots of great tips here, thanks very much!
One thing I like doing with the trigger at slow rates is triggering a slow envelope, which essentially gives you a fourth lane of slowly evolving CV.
Definitely a multi-use beast!
I did not know the importance of the wire being heat-insulating because I did not have sufficient experience Thank you for sharing your experiences with us
Thank you! And yeah, when I was younger I did ruin an iron accidentally by resting the iron on the cord, always look for high-temp silicon!
It’s me, Rat King. Thanks very much for your support!
Hey R.K., thanks for stopping by! The Cell is next, have that one on order, be a while til the video on that goes live, got,lots ahead in the queue. Can't seem to find a Gates kit for sale anywhere, though.
@@CKHaun thanks again for the support. The CELL was a labor of love. Hope you enjoy!
Just two years ago? If it was 5 yrs ago I would think improvements would be made.
I recorded this 2 years ago, the board and kit design are much older than that.
@CKHaun circuit design and board quality is one thing the parts bag inventory count before being sent to customer and instruction manual would be where the quality control would have ample time to correct. You have a parts inventory of your own. Many don't. The odd thing is throwing all the parts into a bowl without a count is where a lot wasted time begins. Otherwise, thanks for the review. I found it helpful.
You're right, an inventory is important. On my vids, though, I approach kits like a 12 year old impatient youngster would and just dive in. Different perspective.
Just bought one of these the other day, waiting for it to arrive. Nice build!
This is a really good one. I tried another and couldn't get it to work, but this one is a champ, you'll have fun.
This was my first kit. I screwed up a pad, so I used a small jumper. It works! Fun kit ❤
Great! That's a excellent practice kit, and glad you got your first re-work in!
I bought one of these as well, and mine also was missing any circuit diagram. I haven't built it yet but I'll be, (trying to..), follow the components on an online photo of this unit that's already built. I have to say that selling a kit without _any _components list or diagram is ASININE. I'm not at all surprised that the kit is no longer on sale. Only when I'm totally confident that I know what goes where, will I be building this. I hope you eventually had success with this.
Yes, irritating. I’m at the point of not purchasing things unless I can preview the paperwork that accompanies.

@@CKHaun a sim legal!!!!!! o frete que está muito pesado!! mais é um excelente projeto!! Aqui no Brazil , não temos profissionais assim!!
O envio é tão alto! Mas acho que você vai gostar.
LESGO TYYY I J GOT A KIT, THIS IS PERFECT
Fantastic!
Great video! I just got this tester to test inverters and power source on my channel and now i can't wait to try it.
It's a good little unit, though I will admit to squinting at the tiny text ;).
I have the Yihua 948-II, which includes SMD rework tools. It's a humbler workhorse at a really good price IMO, and I would certainly recommend Yihua products to others if this is representative of their range.
They're pretty good, yes. I did find Yihuas single-purpose 929D-V through-hole desolder tool to be head and shoulders above even this, it is a superior tool. kzread.info/dash/bejne/lZ6sr9WjeL2qZrA.html
@@CKHaun@CKHaun, I just viewed your other video (thanks for the link), and yes, that looks like a nice piece of kit.
I was quite literally amazed (as you may be able to tell from the video) at how easily it worked and have used it multiple times since successfully.
Very narrow module, nice
Yes, he has a number of very thin ones, handy for a mobile skiff.
I have just put this module together and I do not have output signal, so it might be some problem with my soldering, verified that few times with no,luck, interesting that calibration went well for me
That's too bad! Check diode polarity next, I still put 'em in backwards sometimes.
@@CKHaun Thanks god its working, coupl eod days of resoldering but found that PT2399 was incorrectly plugged into the socket. not its fully tested and working as expected. Already love it
Excellent! And yeah, it's a fun unit.
i think you put too much blow speed it cant get worm that fast when air is literally flying tru that small nozzle I think to you did flow rate to half it would work like charm and ofc more temperature... its not soldering iron its hot air :)
Yes, I dialed it back to about 1/2 later in the vid and it worked better.
Great video as always CK but I noticed you finally got a pair of Weller Xcelite NN7776VN Long Nose Plier...good move on your part!!!
Thanks! Oh, I've had the xcelites for years, I love weller hand tools. They're just usually too long for the size kits I make on the channel. Now, if I do a guitar amp you'll see 'em in there attaching wires deep in a cab!
I bought it like...6 months ago and don't use it that much works awesome but toataly agree, great video CK
Thanks! Yeah, it's one of those tools you don't need often, but when you do it's great to have such a good oe at hand.
Grate video CK have you ever tried the Hako FX 301 it has a electric vacuum pump I have it and I love it it is expensive but worth the money maybe you could do a review of it I have there fx 88D and their fx 951 soldering station love them to what do you think of Hako products
Hako's are fine machines, I have one of their solder stations. But, for me, the diameter of the iron is a bit too big, so I stick with my Weller, when you solder for hours a day little things matter.Also because Weller customer service treated me well 35 years ago. They are a bit pricey for the planned budget on this channel, but I'll see, maybe in the future.
Are all the nozzels the same size ?
No, the nozzles are slightly different diameters. One smaller, one larger, than the installed one.
@@CKHaun are the tips available separarately ?? if so .....thats cool
That I do not know. You might want to ask on the Amazon product page, they may be monitoring and answering.
Looks pretty good as long as one keeps fingers out of the way!
I burn my fingers daily, gotten to the point that I don't really mind any more....
Glad you like it, ordered one a few days ago. £10 delivered from Ali Express. I have a Yihua Soldering Station which works well for me.
This will be a great complement to that solder station.
@@CKHaun Yes I'm sure it will be.
Thanks, C.K. 👍 I've been looking for one of these and could not decide on which one 😉
I think you'll love it. Used it last night on a "real" project and again, de-soldered no fuss in an instant.
Grate video CK.
Thanks! And yeah, there will be a lot more from these folks.
