Electronic Sculpture on Nails



- Circuit on lamps or transistors?

- On the nails.

One type of breadboard is called breadboard, which is strange at first glance, because such a board does not look like a cutting board. And the thing is that when electronic the components were large, the circuits were actually debugged and even assembled for permanent use on cutting boards. Very large components - transformers, lamp panels - were screwed to them, and those parts that were smaller and with flexible leads were soldered to nails hammered into the board. The author of Instructables under the nickname geotek offers the same way to assemble a sculpture scheme on modern components. For example, he makes a symmetric multivibrator, but for example, an amplifier is also suitable.

The master takes a wooden board (suitable for plywood) with dimensions of about 130x80 mm, a printout of the circuit, components, nails and aerosol glue. If the circuit is printed on a laser printer, it can also be glued with PVA glue, if on an inkjet - with glue-pencil.

"If there is nothing at hand but a hammer, everything seems to be nails."

This is not the case; the master has other tools:



This circuit:



The master, having printed on a suitable scale, cuts out (you can take this Pdf file and print on a scale of 1: 1, it turns out the dimensions are about 80x50 mm):



Glues in the middle of the board:




- So you all solder something and look at Yunost.Ru, but you know how to hammer nails?

- Yes.



Having hammered nails in all points of connection of conclusions of components:



The master first winds the nails and solders all the jumpers to them. Those of them that intersect diagonally in the multivibrator circuit are located at different heights. If desired, isolate one of them with a tube. At first glance, nothing will work without acid, but in fact it’s the opposite: you can’t use it, over time it can cause leaks that disrupt the operation of the circuit, and even short circuit. Nails lend themselves perfectly to tinning and without acid.




When all the jumpers are in place:



The master bites off the excess with nippers:



And gets the following result:



Now he tins the caps of all the nails:




Solder resistors to them, first designed to supply bias to the base of transistors:




And then those that limit the current through the LEDs:



And the LEDs themselves also solder, observing the polarity:





And electrolytic capacitors, also observing it:




Transistors master solder according socle:




Connects, observing the polarity, the battery with a block that allows you to turn it off, and the multivibrator "starts up", pay attention to the simplest "pocket" for the battery, consisting of three nails:



Since this is not only an electronic sculpture, but also a training manual, one of its variants was assembled without shortening the conclusions of the components, allowing multiple disassembly and assembly:



In this case, you need to make sure that there is no short circuit anywhere, and since it is impossible to completely eliminate it, it is better to use a salt battery with a low load capacity, because under the components there is a tree.

I drill holes, there are small colored screws, they are well soldered, and it turns out more accurately.
About 20 years ago ... And even 30, damned nineties. He led the radio circle part-time.

cool performance as a breadboard :) victory

I would learn first to distinguish a hammer from a screwdriver and a nail from a screw and a self-tapping screw.
Khatul Madan, I also went to the radio club as a child. I well remember the man who taught us radio business. Horrible swindler. The most affectionate way he addressed us was “morons”. How he examined us! Slightly pull the lamp out of the socket, the glow is on, but the telly does not show. Could the conclusion of some capacitor to eat. I took out the fuses, of course. In this case, the avometer could not give xaxa So look, without a device. In how I trained. Most quickly stopped going to the circle. I and a few others did not quit. In the 9th floor, where I lived, the neighbors wrote to me, a schoolboy, in order to fix the TV or tape recorder. Took for work cheaper than adult uncles - telemasters. And I got money for ice cream and cake and lemonade with triple syrup and cigarettes, too, well, I understand.
In the distant childhood, in a radio circle, we made our own breadboards from contact pads (petals) cut from cans (strips 5 mm wide and then 10 mm long were cut). Then these petals were nailed to a sheet of 3 mm plywood with shoe studs (“texas”), which themselves bent on the back side if working on a metal plate, then the back side was pasted over with a paper so as not to accidentally shorten them. But none of us thought of soldering parts directly to the nails!
What is already there, let’s fuse the diodes ourselves, like radio amateurs in the thirties. ;)
Why go on a dead end road to the Stone Age? Just for the sake of originality?

As such a template, the author used a circuit diagram, but what to hammer into nodal points is not important. An idea was born: hammering staples with a carpentry stapler, having previously treated them with "liquid" tin, it will be more convenient to solder.

Similarly, wiring harnesses in production was carried out.
The only common thing is that nails are clogged in the board. In the manufacture of harnesses, the wires are laid out according to a pattern, one of the primitive options of which is a board with nails. In normal production, not nails are used, but short-threaded pins or studs.
I don’t see anything good in learning how to solder nails. ((

Try to tack a regular nail - be very surprised that you can.
No wonder.You can, not everyone, but you can, you just need to warm it up properly and crawl through it with a sting. Yes, and it is advisable to have a soldering iron to speed up the process. The author of the photograph shows that the nails are copper-plated, therefore they are perfectly soldered from him.
But this is a secondary moment. Please answer the main question:
when the electronic components were large, the circuits were actually debugged and even assembled for permanent use on cutting boards.

Yah?! Do not share a link to examples of such a miracle? ;)
Yes, of course, for very young lovers this is a good method, for example, to learn to solder. But thinking how to breed a board, to carry out installation, it is better on a scarf where there are platforms. In my childhood there were shawls, with platforms cut into squares.
There is a good thing, solder fat is called. It is good to solder nails, other pieces of iron, copper, brass. I have a jar on the desktop, always at hand. But, conductive! It is necessary to wash off. Once in my youth I soldered the board. Well, I think rosin and rosin, what to wash off - that. Then he measured with a tester what leak was on the board-free section of the board - and he understood everything. xaxa

Nailing without acid, anyone can check.
Some steel grades lend themselves well to soldering, others are soldered with great difficulty, they do not want to connect to any solder, nor under any flux. As a rule, mild steels “for nails” are easily soldered. At the household level, this can also be explained by the fact that the material is studded with microscopic craters and irregularities. But there are also electrical brands, especially hard and elastic, and used for shafts, precision mechanics. Here, how lucky ...


But all the same, without stripping off the zinc and acid, it will not tarnish ...

It must be assumed that these are not just nails, but copper-plated nails?
