Loving getting back into electronics as a hobby after a break of many years. Now I work as an EPOS engineer, so I spend my days fixing tills in shops and restaurants, and it feels like I'm doing something I'm actually good at for a living instead of trying to do things I'm not good at! I like to turn my hands to all sorts of things - woodworking, engineering, sewing, cooking, even leatherwork! I occasionally write bad poetry and stories too. But I think I'm best at repairing stuff.

    Make Coiled Wire

    Ok, this somehow applies to those time when you have a commercially coiled wire (like a phone handset), and one of the loops has somehow got flipped the wrong way. I've tried working the flipped part out to the end, but that gives me a looser coil - obviously the pre-reversed version. What's the secret to getting it back to it's proper shape?

  • An experiment in transformer rewinding

    I kind of skipped through the video but it looks really good. I must watch it properly when I have time.Ambitious for a beginner! It could be your old aluminium coils have cracked insulation, causing a shorted turn, or that you didn't make a good enough connection - as you know, you can't solder aluminium without special solder.

  • How to Surface Mount Solder Using Solder Paste

    I tried this technique a few years ago using a heat gun and it was a disaster! The solder wouldn't melt whilst it seemed the chip was getting excessively hot.However you have inspired me to try again. I'll try making longer pads like you have, maybe that is what makes the difference.

    How to Build Circuits

    It's a good start but it looks as though you haven't read what you've written! There are a few bloopers in there ;)Not a good move saying that "we use 1/4 watt resistors in DC circuits". It's just a commonly used rating. Sometimes you need them to be bigger than that, especially if you are just experimenting, and for commercial designs at least, they are often smaller. The same is true with AC circuits, which also use resistors of all types.Also, you can't make the statement for all transistors that the collector connects to positive and the emitter connects to negative, as this is only true for NPN transistors.I look forward to more from you :)

  • How to Prototype Without Using Printed Circuit Boards

    Really good instructable. Very nice construction. I actually found this because I was looking to see if there's a "standard" way to use perf-board.Couple of things spring to mind.I've been using wire taken out of solid core cat5 cable for this. It's an incredibly bad idea, the insulation shrinks back when soldered and melts through when the wire gets hot! So if anyone was thinking of using it, don't!I've used Vero-wire for this in the past, which works really well. Much easier than having to strip individual wires. You get a special wiring pen which you thread the wire through. I think the Vero wire is the same as solderable magnet wire, and I'm about to try building a prototype on perf-board using some from an old signal tranformer. Wish me luck!

    Simple Sheet Metal Brake: No Welding

    Great piece of work! I made a similar one a year or two back using using pieces of Dexion style racking. It's not entirely straight so the bends are a little off, and I pop-rivetted the hinges to one of the pieces, and they tend to move slightly. But it just about does the job, way better than the "vice and bash" method anyway. I can see your build is infinitely better. Screwing the hinges down to my bottom piece of wood is one idea I'm definitely taking! Maybe one day I'll get some angle iron from somewhere...

    Chunks of closed cell packaging foam would work as springs.

  • How to make a printed circuit board (PCB) using the UV light LED method.

    I changed the power supply arrangement so it runs directly off the mains (at the moment an isolation transformer whilst I test things). I discovered that the mains voltage can change by as much as +10% and -6% in the UK, so I found this voltage limiting circuit to keep the DC down to 300V. The 3 4k7 resistors drop 84V each, and the 3 LM317's provide 18mA per series chain of 66 LED's. (see pdf)I used cheap prototype board off eBay, but the 198 LED's don't quite fit, so there are a couple in odd places!I have mostly made a box 11" deep with the board this is mounted on forming the base. It's not a very good box - I need to find one like yours!Thanks for a great instructable :)

    You'll burn out the potentiometer that way. They have *tiny* power ratings at the wiper contact, unless you use one that is designed for higher power.

    Nice educational project. You really should mount the mosfet the other way on the heatsink though, so that most of its body is in contact with the metal

    Tables of 6, 7, 8 and 9 in your hands

    So for the x6, x7, x8 and x9 tables, each of which contains 12 individual questions and answers, ok so we'll just use the combinations of those numbers alone, giving 10 combinations to memorise I think, how is that less to remember than 4 simple operations?Some of us are stuck having to calculate x6, x7, x8 and x9 every time we encounter them. Are you saying we don't understand multiplication because we are unable to remember the result the next day (or hour, or minute)?And isn't the act of brute-force memory a "trick" or "short cut" in itself? No-one who can remember that 4x4=16, ever needs to understand that 4x4 = 4+4+4+4.As a tool for people who simple can't remember those higher multiplications, this is an ingenious system, and one I will be using

    You don't memorise the number of every finger, you just start at your thumbs and count down. I did this in my head just to see if I could. So much easier than remembering lists of multiplications.

    This is brilliant. I never learned my tables (apart from 2, 5, 10 and 11) as a kid, and have always had to work out the other multiplations when I need them. The ones up to 5 are easy to do, for 6's you do x5 and add another one. For 7's I have to do x5 and add it to x2, and for 8's it's either do x10 and take away x2, or do x5 and add x2 and another one.All my life I have done this, though as time has gone by I've started to remember the memorable ones or the ones I use a lot.So your method is brilliant, so easy!To those commentators below who say anyone can remember lists and other rubbish like that, it simply isn't true and makes me quite angry.

Structured information causes me problems, lists cause me problems, remembering lists of structured information simply isn't worth the effort and anxiety it causes (because I have to check everything I'm supposed to have remembered anyway), and is highly risky of getting wrong.For me it is easy and natural to visualise an object in 3d, be able to turn it around, and see the parts and how it fits together, in my head. Sometimes I can also visualise parts moving, rotation, electron flow, things like that. I think that serves me better than remembering any amount of lists.

    Nice, but you missed a couple of methods out!Old fashioned linear spped control, which is like your potentiomer but has an amplifier to drive the motor (so you can use a bigger motor) - still inefficient though. You can use error correction feedback to get accurate control.PWM using 2x 555 timers - this way you have 1 timer to generate the pulses, the other to control the mark/space ratio, which gives you two advantages: 1) you can control it with any voltage source, not just a potentiometer, 2) the frequency of the PWM signal does not change (which it does with the 1x 555 method)
