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. Called "The David Attenborough of build videos" by one subscriber....
Thanks! One of the more straightforward clocks I've done, and having the case being fully molded parts, instead of single sheets screwed together, makes a much more attractive finished product.
What temperature should I set my soldering iron to when doing this kit? I'm JUST starting out so if there's a general rule of thumb, I'm not aware of it yet, so I apologize in advance.
I would recommend somewhere between 600-650 degree F./315-345 degree C. That's hot enough to melt solder reasonably easily, but not so hot that you'll have to move too fast, so try 625 if you're starting out. I run 675 on my iron, but that's based on many yers of experience. Going lower when starting will keep you from cooking components.
Sure, I buy Whadda kits from Jameco in California; www.jameco.com/z/WSMI198-Velleman-Velleman-LED-Buddy-Kit-Solder-Assembly-Required-by-Whadda_2355119.html
@@CKHaun awesome thanks!!! Looks like Amazon has it too by typing in valleman LED buddy. I see there are knobs for voltage and current. How do you set those to not blow the LED you're testing before you test it? With volt meter? Thank you so much this is really useful. I love useful kits like the power supply and this haha
Useful tools are just good to have! As for setting the voltage, I usually use 5 volts, and the tester displays the voltage you're using, so you don't need a voltmeter. A fun tool.
The video was great, but I'm bit struggling with understanding the purpose of it. Maybe for the disabled/elderly, but for other things, I don't see any purpose at all. If you can maybe explain a little bit, I would be much appreciated.
Yes, the uses you describe are certainly ones that this is good for. The goal of the kit is also to show how to use a sensor (like the microphone) to trigger an opamp to set a relay. Also shows how to have two different power sources in the same package doing different things. The schematic is the main thing to study, and look at the circuit board to follow all the flows. Not practical itself, maybe, just for learning.
Hello C.K. Do you still have that old video from your previous attempt? I have the same kit as that one but no0 manual. I flagged your video for later usage but when i wanted to start yesterday it was gone. Oh the horror... 3 hour search for your page. I know it wasn't flawless, but, combined with the comments, it was VERY usefull, because it was probably the only one for this version speaker. It also contained the QR code with the download link for the manual. Regards,
Hm, I did take its down because so many people mis-interpreted *why* I left it up. But here's the link to the assembly guide, and thanks for asking! m.media-amazon.com/images/I/A1ZN9nyFVUL.pdf
@@CKHaun Thanks a million for the manual. If I remember correctly you placed the chip the wrong way around. But that's not the end of the world. The video gave a perfect view on how to solder things with the correct techniques. For a total newby like me it was priceless so PLEASE put it back up again, with a disclaimer or something. Greetings from the Netherlands
I do still have the video, and based on your thoughtful feedback I think I will add an intro piece and re-upload. Will take a few days since I have other things in the queue. Thanks.
This is something i've been looking for. Now i just have to find retailer that sell it. I might have missed something, but can it show date in dd/mm format?
I have one of these making its way out to me from Portland. So glad you got footage of your build! Thank you for sharing. I built two of the AI Synthesis mults and I have ordered the LPG, matrix mixer and this harmonic mixer.
@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.
@@CKHaun I am glad I got one! Thonk has only two left in stock now. I think I should get another, lol. I am so excited to hear it! I have 4 other not Serge kits I am going to assemble before I unwrap the Serge kit. Those are my practice kits I suppose. I want to brush up on my soldering skill/knowledge before going full hog on the VCFS. It was more than double the cost of the other modules. I am very hopeful that my kit also has the SMT alternative diodes that came with your kit. I can do decent THT but no SMT skills are in me at all. Not even a little.
Aw, give SMD a try! I actually find it faster than TH many times Might want to practice on something like this, a practice kit from Gikfun ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Ibi-Gz-3YYo.htmlsi=n-s2sx23rDYvaiw0
@@CKHaun I own a different colored gikfun smt kit but I cannot understand how I can solder things that are so small that a single drop of solder would bridge 10-12 pin connections with ease. Maybe my tools are wrong but no soldering tip sold on the civilian market is even remotely small enough to solder one of the items that came included in my gikfun kit. not to mention that soldering wire itself can hold two of the little chips or diodes on the tip, like the tip of a pin sort of tip. The actual soldering wire is several times larger than what I am supposed to soldering. The things included that I am supposed to solder are small enough to sit inside of a typed letter o and not touch the letter. So after looking for about a year for the tool that could do the job, I just stopped looking. It's just not possible to find soldering tips that can produce a drop that is small enough, on the open market, or in that year I'd have found one. Perhaps defense contractors or the folks at the National Research Labs around the country have access to specialized gear but all I can find is an iron. And compared to the center of a typed letter o, irons and their tips are well past massive. Every tip is way way way too big to come close to touching only one, and not 6-8 pins simultaneously. I think at best all I will ever be able to manage is THT.
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.
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
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.
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 🙂
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.
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.
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.
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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-cjxMsjHZD6M.html
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.
