=======================================HIGH-TECH!======== In this section, I will talk (as the title suggests) about various home technologies for making something related to the spectrum. Because for some (perhaps) even making a hole in the case for a toggle switch seems impossible (like - how and with what to do it?). In the first article, I will explain how to make a not very complicated printed circuit board at home! For example, you need to connect an EGA monitor (in the second issue - pc>>zx will be about them!), well, you can't do it with wires, it can be done on a board, so it looks cool, and it’s nice to do it yourself! I will explain how to make boards with a minimum of various special devices, using various improvised items! [Chapter 1.] [About the drill] First, you need to acquire a drilling unit - you can't do without it! You can buy a chuck that holds the drill bits, it's called a "collet," and it comes with a set of 7 interchangeable "collets" (strange name, don't you think?), and you can buy such a thing in any store that sells radio components, and then find a suitable motor that works at a voltage of about 12 to 24 (for example, I have one for 24, from some printer, it's a stepper motor, very powerful!). Well, this chuck is mounted on the shaft of the motor and secured with a burr (four screws, by the way, so it doesn’t fall off). [Chapter 2.] [Voltage selector] Then (for complete happiness) you can build a separate power supply with a voltage regulator at the output, and you can smoothly regulate the rotation speed! Do you think it's difficult to make one? It is, but now I will tell you about a clever (non-standard) circuit for connecting everyone's favorite microchip 7805, or as we call it - KPEH5! In short, connect everything as usual - the first leg to the input, take the output from the third, and here’s the secret - the second leg is connected not to GND, but to a variable resistor of about 4.7 kilohms, the other end of which is connected to GND. And that’s it!!! When the resistor is set to 0 ohms - the output is the usual +5V, but as soon as the resistance increases, the output voltage does too! It increases somewhere up to 4.7k! The maximum voltage can be easily calculated - it’s the input voltage of the 7805 minus about five volts! So it’s best to apply about 16-17 volts to the input and you will get about 12V max at the output! [Chapter 3.] [One last time about the drill] And now you have a compact drill that can hold drill bits from 0.1 (!) to 4 millimeters! The most common size, I’ll say right away - 1mm, because 1.5mm holes, for example - are only for powerful transistors and resistors, and for all microchips in DIP packages, 1mm is just right! I once tried to drill with a 0.5 drill - immediately broke it accidentally, it’s so fragile - terrible! [Chapter 4.] [About the papers] Well, when the drill is ready, you can start. Draw the board (in scale 1:1, of course) on a piece of paper, preferably on graph paper (or whatever it’s called), and start the most important thing - think about how to place the components and route the tracks so that they don’t intersect and connect everything with everything. (?) If the board is double-sided - then draw two such boards right away and draw the tracks on the second one just like on the first (meaning - draw on the same side of the paper), and when everything is ready - place the second paper on something light (so it shines through), even on the window, and trace the tracks again (from the other side of the paper, the bottom side). [Chapter 5.] [Cut and glue] Done? Now cut out a piece of fiberglass according to the size of your board! If you have nothing to cut it with - you can, as a last resort, cut it with scissors, just not your own, because they get dull quickly from such execution! Now scratch it a little with something, as it probably oxidized and darkened while lying around! Well, did it shine a bit? Then you need to glue the papers you drew onto it. Just don’t mix up which side is up and which is down! It’s best to glue "with soap," i.e., you take it, wet it a little with water, soap the fiberglass, and stick the paper on. It holds well, by the way, and comes off easily. [Chapter 6.] [Mark the holes] When you’ve glued it - take something sharp and poke it at the spot where the hole will be drilled (you marked them all when you figured out where to route the tracks). And give it a light tap. There should be a dent left on the fiberglass! And do this for all future holes. Then peel the paper off, rinse it with water, dry it, and check the holes. [Chapter 7.] [Make a drawing tool and draw] Ready? Now take an empty pen refill - gel or regular ballpoint - your choice, and dig out the ball from it. (You pull the metal tip out of the tube and insert a needle into the end where the tube was inserted. The ball falls out.) Now take nail polish, fill your modified refill without the ball with it, and draw the tracks on the board. The thickness of the tracks, of course, leaves much to be desired, but still, if you try...) Also draw circles around all the holes - like they will be contact pads. The polish dries - if it’s crooked somewhere, peel off the polish in that place with something (even with untrimmed nails for a month) and draw again. [Chapter 8.] [Put in a jar and sleep] Now take some jar, pour a little water into it (very hot - it dissolves better) and add some copper sulfate (that blue powder), it’s like some fertilizer, buy it in some flower shop) and salt (regular) at a ratio of 1:3, i.e., for example, 1 teaspoon of copper sulfate and 3 teaspoons of salt! The most realistic ratio, by the way, I calculated myself! Mix it all well, and put your board in there. And go to sleep. [Chapter 9.] [Wake up - almost ready!] Good morning! Run to check how the board is doing! Most likely, everything is ready, and where there was no polish, the copper has already dissolved! If it hasn’t dissolved everywhere - place the jar in a warm place and stir it a bit with something. The warmer the water - the faster the process goes. (Just don’t try to boil it - the polish is for nails) I once hung the jar over my desk lamp and stirred it often with a plastic spoon (very convenient, by the way), and everything dissolved in an hour and a half!!! Now peel off the polish, rinse the board with water, dry it, and tin it. It’s better to coat it with rosin flux right away - then it will tin very well! And it's done! If nothing worked out - it’s not a problem, I’m not to blame, if it worked - well done, use it and enjoy!
