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.

  • Arduino VFD Display Clock Tutorial - a Guide to VFD Displays

    I really like this project, thank you for taking the trouble to document your efforts.I've always liked VFDs and have just ordered one (well, 2 actually) 9 digit + dp + comma + arrow-below-digit to display the frequency of a signal generator (using AD9850 eBay module) I'm designing. 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. They do bigger versions for more segments and more keys.Your instructable actually came up as the only search result when I was searching to find out about fake versions of this chip!

    DIY Professional 18650 Battery Pack

    You can get 18650's with tabs pre-welded on, so you can just solder the tabs together. I've done this with NiMH cells and it worked really well.Also the type of welder for battery tabs is a capacitive discharge welder, I've not tried it but looks easy to build a simple version, much cheaper than buying one. Lots of CDW projects on the 'net!

  • Tales From the Chip: LM1875 Audio Amplifier

    It looks like it's there to ensure C1 always gets discharged

    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.

    Thanks for the informative instructable - I knew nothing about these "chipamps" until today! Also thanks for the great link to the Analog .pdf on decoupling. Just what I needed!

    5V Mini Portable Power Supply

    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!

    Very informative piece, thank you.I bought a very cheap crimping tool which looks a lot like yours, and found it has a peculiar problem - instead of curling the "conductor crimp" around into two neat humps, it pushes them down so I get a partial crimp with a gap in the middle and two little flanges on the the back. I made a quite a few of these before I realised there was a problem. So I bought another very cheap crimping tool of different design, which also doesn't crimp properly but does form the "conductor crimp" into a better shape.So now I start the crimp off with the second tool I bought, and finish it with the first one, the result being quite good looking crimps.

  • 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. It doesn't fill gaps and it's brittle (and you can't adjust the join!). I'd be more inclined to use a gen...

  • 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!

  • PCB ETCHING | TONER TRANSFER METHOD

    Nice instructable. Couple of points (well, 3)You don't want the iron at maximum temperature, you just need it hot enough to make the toner melt and stick. 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".

    Nice instructable. Couple of points (well, 3)You don't want the iron at maximum temperature, you just need it hot enough to make the toner melt and stick. 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).

    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.

    PCB Etching Using OHP sheets

    OHP = Over Head Projector. Used in classrooms and meeting rooms etc, or they used to be. The sheets are what you draw or print your "slides" on.

    Nice work. Did you find this gives you better results than using shiny paper?

    Very impressive work! I wondered how to make a solder mask, now I know :D. I was half expecting you to do through hole plating into the bargain as well! Now it would be really nice to if you show us a cheap way to do silkscreen as well ;)

  • 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.

    I wonder if this would be a good replacement for injection moulded plastic headphone plug bodies????? I've been using hot-melt glue but it's a little bit soft. Epoxy putty is too hard.

    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 :)
