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.

  • 10 DIY Alternatives to Off-The-Shelf Electronics Components

    Great idea with the PVC pipe. I never thought of re-forming it before. I've done the trick the the PP3 battery connector years ago, it's a really good idea. I'm also a big fan of re-using wires. Old CAT5 cable is also good for breadboards. You actually get a better connection if you use the stranded sort though. You can strip old multi-core cable for hook-up wire too.I don't like using non-insulated croc clips because they tend to short too easily. You can improve the connection on the bought leads though by soldering the connection or even just crimping it a bit tighter.Nice and useful information though - keep on experimenting!

    It's the same wire as the leads going into a manufactured light bulb, so you could break open a blown bulb and re-use the wires.

    Fizzle Loop Synth II

    I love this. Way back when I was young in the 80's I tried combining oscillators to get interesting sounds (didn't really understand what I was doing, but hey), but the Fizzle Loop is better by a long, long way. I enjoyed finding out what a Vactrol is - I'd never heard of them before. It would be interesting to find out what changes if you used a bulb rather than an LED.I might actually build this.

    This is so clever, I'm very impressed!If you solder both ends of the LED to the middle of a piece of 0.1mm magnet wire and then cut away the bit in between, you will get super-fine leads and not hard to solder.You could analogue-multiplex a load of them and get some really nice effects!

  • Turn Your Old Plates to Decorative Plates

    It's an interesting point, having read the conversation following your comment. If you look at mass-produced objects, the irregulatiies you get with articles which have been hand made (or at least, hand-finished), no matter how accurately done, always make it look far better than the precise lines you get with patterns cut out by a machine. Nothing can imitate the human touch. (well, not yet anyway!) even to the point where a hand drawn pattern has been machine cut (or painted), it still looks worse than if it's been hand cut/painted.

At the time (2010) there didn't seem to be any commercial recycling of it, just a big machine you could buy to melt it down by the cubic meter (or more) into blocks for compact disposal.I was pleased to discover that apart from the space it takes up in landfill it is a "less bad" plastic because it isn't derived from oil as other plastics are.Could heat alone get the bubbles out?

I only have 6 pins available on my micro, so found the (serial input) PT6315 which will support 9 digits x 19 segments - might be suitable for one of those fancy VFD's you played with. It also can scan a keypad.

    You could but you will have to adjust R2 and R1 to get a fairly low gain. I don't know the power of headphones but I think it's in the order of a few hundred milliwatts, so I'd try a gain of 10 to start with and increase or decrease from there.

    What a great idea! I like that it is made on the battery clip so you don't have an extra "box" connected.Would be even better if you could make a version using a buck converter. MC34063 is easy to use, common, and cheap!

    I also think it would be a good idea if you have a protection diode connected backwards across the battery, so if you accidentally try to put the clip on the wrong way it will short circuit the battery instead of destroying the regulator!

  • Spot Welder From a Microwave Oven Transformer and Water Tank

    The reason is as you say. The only caveat for using another type is that it be big enough. The steel of the transformer has to be able to carry a lot of magnetism due to the high current involved. Modern microwave ovens are typically rated at 800 watts. This translates to a transformer of roughly 1000 VA (if I've understood the maths right) which would be very expensive to buy. Even a MOT is only just adequate for this task.People throw out microwave ovens all the time, so it's easy to get a transformer from one for free! (Unless it's an "inverter" type which is not suitable)I have considered getting a used "site transformer" (such as building contractors use) to re-wind, but some of these are potted in extremely tough resin, so would be hard to modify.

  • DIY Variable Power Supply With Adjustable Voltage and Current

    Nice project. But please edit the specification so it shows what it will actually do, rather than just the min/max for the module you used. It's worth noting that at lower output voltages than the input (buck mode), this type of supply can output more current than it's input current, and at higher voltages (boost mode) than the input there will be less current available as it will draw a lot more from it's power source.50mV ripple isn't terribly good. An LC filter on the output like another commentator shows would be a big help. Use thick wire for the inductor though or you may get an unacceptable voltage drop.Nice case, though I don't think super-glue is a very good choice of glue.

    I've often wondered how to disassemble a bearing - now I know! Thanks!Now, the big questions is, do you have a method for use with metal-caged bearings? (which look as if the cage is welded between the balls)

  • 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!

    If you saw an instructable about how to make a bag, would you be commenting on how easy it is to buy a bag somewhere? Or are you just doing free advertising for this company?It really peeves me how every time there is a discussion somewhere about methods of home PCB fab, someone has to chirp up about how their favourite company is so good, and why I should pay to have so many made of my 1 off never again board.

I get sponsored gmail from fab houses every day!Yes it takes more of your time this way, and may have the side effect that you acquire some more knowledge on the way, and possibly have to learn things you never thought you'd need, which is very undesirable to some people, it's true.But at least if I want a board today, I can make it today and not have to wait 3 weeks for the fab house, and if I find I've messed up my design (as often happens) I don't have a stack of boards sitting there not only redundant, but also wrong.

    Modular UV LED Exposure Unit

    I made one similar to this a while ago, it works very well, so UV LED's certainly work. My power supply is different though, I published the schematic here (PDF in step 1): https://www.instructables.com/id/Somewhat-Complete-PCB-Fabrication/

    A Simpler Tripod

    Nice work!I'm thinking the block at the top would be very hard to make (accurately) for someone who doesn't have a saw like yours. I think if I were to make one of these I'd bend a bit of sheet steel to fit. Not nearly as nice, but a lot easier to work.My other thought is, if I were to make this, I would make the folding legs a bit longer so the camera sits more centrally on the tripod.My other other thought is, I'd never heard of plasti-dip before, looks like excellent stuff :)

    Laser-powered Light Saber

    Wow, just wow!I wonder if you had a slight diverging lens on each beam if it would make them "disappear" more effectively beyond the point where they cross. Possibly would also produce a more "solid" effect.FYI, normal laser pointers are class 1 I believe, less than 1mW. The 5mW ones you are using are class 3a and aren't intended to be used in a pointer kind of way. There are a few guides to the classifications but this one is pretty clear: https://ehs.research.uiowa.edu/laser-classification
