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.

  • Unusual Uses for Broken & Dull Drill Bits

    2 comments in one here:With broken larger bits, you can wrap a piece of sheet metal around the fluted part (I used a bit of old copper) then it will stay in place in the chuck much better! I have a broken 5mm bit I've been using for years that way!I used to drill holes in glass bottles when I was a kid. My Very Old Book said use a broken off piece of hardened silver steel rod, but I found broken off drill bits did the job just fine (yes, I used to break them on purpose for this!)

    Superb Lab Power Supply

    There seems to be a glut of psu projects using this kit, but I like what you've done with it. I'm quite impressed with your meter and it's little "sliders" - really cool!Great work on the case cutouts too, really nicely done. One small suggestion, look into using waterslide transfer film (decal film) for your text. It's what I'll be using on a project of my own, it's really good because you can print a sheet as big as your front panel, slide it on and your text and other print is in just the right place and any colour you like!

  • DIY Cathode Ray Tube: Interacting With Electrons

    Please correct me if I'm wrong, but I think this tube may be a good source of X-rays, very dangerous! I wouldn't run it for long for that reason alone.If you lower the pressure of the tube more (but still not a vacuum) you can see other phenomena, like Crookes dark space, and other kinds of banding. (I made a similar kind of tube back in the '80's using pennies for the electrodes) Something else really interesting I observed was teeny-tiny ball lightening that drifted down the tube.Have fun with your tube but be safe!

  • From Resistors to ICs Color Codes

    Perhaps you can help with an identification. I have some board-pulled small (about 2.5mm long) glass bodied, leaded diodes which came from Sony or Panasonic audio gear, possibly dating from the late '90's. Some have a single green cathode band, some have a single white cathode band, also some shorter ones with a blue band (which came from something else though I think they might be zeners). I can't imagine they'd be anything other than general purpose diodes. The white band ones have a near identical Vf to a random 1N4148 I sampled.You seem like you might be able suggest what type they might be!

    How to Fix Broken Headphone Jack !

    Nice 'ible, well done! Nice to see you finding a way to use the original barrel of the plug instead of buying a new one!A couple of tips for you, since I have done a few of these.Use a spare headphone jack to hold the plug whilst you solder. It's much easier because you can clamp it in a vice or whatever, and it protects the plug.If you are careful, you can often save the original outer jacket from these moulded plugs because it's made of rubber and if you slice it open down one side you can peel it back from the plastic which is injection moulded over the plug connections. When you come to re-assemble, fill the space inside the plug with hot glue and use super-glue to stick the edges of the jacket back together. With care, you can hardly tell it's been fixed :)

    That paint will just burn off when you solder the wires. You don't need to clean them!

  • Sound Bending Machine - Intro to Circuit Bending

    S/He means the jack has a built in switch, so when you plug something in it breaks the circuit with one wire of the speaker and connects the plug instead. Easy to see it when you look at one of the sockets.

    All it will do is lose more signal in the p/d. I'm assuming the speaker output is designed to provide a current into a low impedance load. If you connect a higher impedance load you lose signal due to the mis-match, so although adding resistors can improve the match, it won't do anything to recover lost signal.On the other hand, if it can drive a speaker, it probably won't have a problem driving something more sensitive anyway.

  • Sound Bending Machine - Intro to Circuit Bending

    I found a data sheet for the chip - it is designed to drive a speaker directly. If you want an output with higher impedance, the easiest thing to use is a small transistor radio output transformer (eg, LT700) connected in reverse to the board's speaker terminals.

    This is such a cool project! I love the way you've re-purposed the intercom!

You have to experiment to find what temperature it needs to be but try between 80-100 deg. C. The reason is that when it's too hot the toner spreads out to the sides so your tracks look lumpy. It doesn't apply with your OHP sheets, but if you use paper it also makes the toner melt into the pores of the paper so it doesn't come away as effectively.I've tried glossy paper from flyers and magazines, inkjet photo paper, normal printer paper, and cheap Chinese made yellow "toner transfer paper".

I've never tried transparency sheets like you, but I got some for another purpose recently (dry film method) and find them a bit expensive to use for toner transfer.The yellow transfer paper works best. It has a very thin plasticky film which sticks to the toner and makes it a bit more sealed. The worst thing was normal printer paper.When you clean the board it's better to use very fine abrasive "wet and dry" paper, such as 1000 or 1200 grit. Use small circular motions with a bit of detergent, then wash off with lots of water. It works much better than side-side motion. The board can be too shiny, and the abrasive paper leaves a better surface for the toner to stick to (like when you glue something).

    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!

  • 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 :)

    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. I am a highly visual thinker, and dyslexic. Structured information causes me problems, lists cause me problems, remembering lists of structu...

I am a highly visual thinker, and dyslexic. 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.

    Coconut Cracker

    Only done it once or twice, worked a treat, you just wait for the crack sound. Was a gas oven, setting 1/2 or 1/4 - don't know what that is deg F or C

    Coconut Cracker

    I think this has just become my favourite instructable. Just love it.Of course, whilst your dad was smashing coconuts, your mum really ought to have been telling you that you can crack them by putting them in a low oven for a while. Not as much fun though...

    Legaly compliant laser pointers are too weak to do any damage - it's still unpleasant though.
