Solve : Color Codes used in electronics? |
|
Answer» Looking for color codes for some project? We were taught with "Billy brown revives on your gin but prefers good whisky"That is a neat way of remembering which B is black and which B is brown at the beginning of BBROYGBVGW. I think the mnemonics which NAME at least one colour are good. Actually if you remember the rainbow (minus indigo) you have 2 to 7 and you can say black (0) is zero brightness, and brown (1) fits in after, so you have to recall grey and white somehow. I used to say white (9) is at the end (the opposite of black) so now I know where grey ( goes. I expect that like anything, if you deal with them frequently enough, eventually you memorize the colour codes. I seem to remember that at some point I had them memorized and could easily read resistors and such, but that was only when I was dealing with them everyday in a tech class. In hindsight it was actually quite a cool little class. We did a bunch of different projects where we etched our own hand-traced PCBs and mounted appropriate through-hole components to do simple things like make LEDs blink, pulsate, or a series of lights do different things. My favourite was the final project where we had to wire up a grid of LEDs and connected the grid with a double-sided PCB to an IC and a EPROM that we wrote data on to make the LED grid display our names. At this point I've forgotten nearly everything I learned. Quote from: BC_Programmer on July 02, 2017, 02:55:54 PM where we etched our own hand-traced PCBsI used to use etch-resist pens. Back in the 70s. The fumes from the etching bath... I can still remember the smell. Ferric chloride? Can't remember. Won't Google it. Now you can use a laser printer to print the pattern on the right paper and transfer the toner onto the copper using a clothes iron (apparently). Yes, it was Ferric chloride.
