I learned this technic in the late 70's, has a way to build light weight project. Today, the good old perforated board is obselete and hard to find ... Good video. Hope to see other soon. I will try it but with a good old LM 741.
I had the great fortune of meeting the late great and prolific Jim Williams. He came to our company to consult with us and I was his contact. If you don't know who Jim Williams was, he was the Staff Scientist at Linear Technologies semiconductors. He was prolific at writing some of the best analog app notes I have ever learned from. This was maybe the best linear semiconductor electronics company for many years, but was purchased by Analog Devices a few years ago. If you have seen pictures of his bench, then you have seen it covered in piles of Many experimental and prototype constructions like the ones discussed in this video. I use this method quite a bit. Easy and works very well for testing circuits.
I'm glad you could take away good things from Alexi, many would have shrugged that experience off and looked down on the opportunity. We'll show those SMD builders and corporations trying to miniaturize the hobbyist out of the equation, their little bits are just gonna short out on our boards! I'm glad to stumble upon a wild man keeping it real. This helps me to feel better about the state of my builds which involves some direct component connections, vero board, etc. A guy could really go to the deep end attempting mastery with these techniques, probably not where I'm headed but very interesting to see. I'm hoping to tailor some basic low budget circuits to suit whatever cheap enclosures I can muster, so the product is the same but the package differs as I switch to the some other enclosure for the next format.
Great video! Just info: you can probably turn off autofocus on your camera. Then you can manually set the focus to your workpiece. That would make for a more pleasant viewing experience.
If you use a bit of thermal grease under the 5532 it will hold it in place as well as dissipate any heat it may generate. You can do the same with the transistors.
Wow! Cool! I had no idea that this was a thing. I kind of self taught to build ugly circuits on cardboard paper, but it doesn't stay intact and has varying degrees of resistance depending on moisture levels, which limits me to using low resistance values in my designs.
ye thats actually interesting, i got a Pioneer sa7800 that had an fix attempt, that was used this technique but with glue, the diy amplifier was made on a board like this, and everything in air, and a tonn of glue everywhere, it exploded when i turned on the unit. So at least i still had the original stuff left intact mostly in the amp that i got, and i fully rebuilt it to be as original as possible, and now i have a very nice Pioneer sa7800 amplifier.
Dead bug construction? Don't know that one. But I have used the term Rats Nest for over 50 years to describe the seemingly higgle piggle of prototyping loose discrete and IC components into a working entity. Where its a fine balance between something logical on a bit of paper and still ideas in the mind, blended into a "Yeah that's right, it works" of wire and solder and this and that, be it on copper or "loosely" arranged.
How do you call those? -> There's also circuits I saw that look like some industrial plant or little sculpture. They mainly use cooper hanger or different gauges of copper rods. Components are suspended and there's no enclosure - Although I saw some home maid guitar pedal structured like this inside. I find all these approaches very interesting and inspiring.
rofl in highschool i found a circuit for an FM transmitter online, "stole" the components from school, wound my own transformer, and even BARELY got it to work. soldering all the component leads together in some 3d maze. i built it so i could listen to my rio pmp300 through my 1st car's stereo through the radio EDIT: it was also during this time that i learned accidentally hooking an electrolytic cap backwards will make it explode. scared the hell out of me.
Isn't the opamp output normally placed between the two diodes? Given it's in closed loop the circuit should still work, but I'm guessing in this configuration you'll be driving one BJT harder than the other

Really enjoyable video, thank you!
This is your only video? It is nicely done. Please make more. Interested in your take and style. Subscribed.

Thanks John. Jim was totally an analog guru: Fitting tribute www.eetimes.com/photo-gallery-remembering-jim-williams/
Thanks for sharing your experience! I am particularly fond of AN-120, there are plenty of beautiful examples of his prototyping.
This is empowering.

Very fitting that your first video is about Manhattan-style prototyping 😁

Thanks for your comment SashaXXY. Best!

Sometimes ugly means beautiful!
Great content, keep up the videos!
Thank you for your comment.

I know some folks who will only build on commercially fabricated PCB's, but I'd still call their work 'ugly construction'.

Hi Vasily,nice quide for ungly "american" constraction....73
Thank you
I call them 3d structured circuits d3dbug is a cooler name for what it is
I like your term. Big thanks
