I am not using breadboards often, and now I know why: I was not using them in an effective way. Your video definitely gave me some good tips that I wil put to good use ! Thanks for that, and happy 2024 !

For jumpers I mostly use the old telephone installation copper wire, but the one that was used on the street that had 2 or 4 solid copper wires in parallel with a steel tensioning wire. It was once ubiquitous before the fiber optics rollout.

I am 78. An HGV mechanic since leaving school at 14 years old, gradually moved into auto DC electronics and loved it. However I only got as far as unit changing if the vehicle on-boards and plug in computers told me to do. I never got as far as delving into things to any depth. Obviously had to learn OHMS law etc etc. March this year I decided to get into model electric trains ( now long retired) as a hobby and was very surprised at the electronics involved. Basically I wanted to light my lay-out buildings, platforms, roads etc and set about learning the more refined use of resistors etc (I never knew that I could burn a resistor out as such and had to check its actual wattage). I set about wiring my invention and had visions of wiring in a relay to make things work, such as on a lorry a 3v signal load going to a relay to fire up a 24v lamp circuit, if you follow my meaning. I have lighting systems in place that work ok but are loads of separate lamps, powered by a variety of batteries, with one lot of about 10 LEDs powered off the main Varying power supply from 3v up to 6 v ( all via a million resistors)I came across you and your tutorials and decided to learn more. I suppose I am trying to run before I can walk. Can you advise the best way I can (at my age) learn some basic modern electronics to suit my railway project. I am too old to start with learning DC electronics at apprentice lever, probably haven’t got much time left. A quick flick through your videos didn’t really help me, am I missing your start up to this subject. Many thanks anyway, and I sure those with far greater knowledge than me find your videos like gold.

Hi thanks for the comment and your story. There are 1000's of basic electronics tutorials on KZbin. Don't limit yourself to one channel, there are many out there. I suggest you stick with it. If you find something of interest, search for that specific topic title and try to watch/listen to several different youtuber's versions of it. You will find it all sinks into place. My channel is quite small at present, but I recently retired and now I have time on my hands I will be publishing new videos much more frequently. So make sure you Subscribe. In my experience, everything boils down to ohms law in the end, so you already have a good starting point.

@@paulpkae Thankyou. I had already subscribed to your channel. You have the same accent as me and I find you easy to listen to and follow, plus you tend to slide above me in terms of technology explanations, but it’s easy to go back to and listen again. I will follow your advice and search for specialised content rather than my current way of trying to learn from the beginning but jumping into the deep stuff. Again, many thanks and I’ll keep an eye out on your channel.

I like the resistor pack idea. I've been using resistor arrays, which do a similar thing but are more expensive and take up more space but are discrete resistors. Which can be good and bad. For LEDs it's bad because you need a bunch more wires. Your method seems a lot nicer. I will have to try that! For some reason I thought the resistor pack/networks were in series, not parallel to the first pin.

@paulpkae 11 ай бұрын

Thanks for your comment. I think resistor packs come in varying arrangements, but the vast majority are in parallel to a common pin.

@Sembazuru 11 ай бұрын

For LEDs, especially if most of your projects are 5V or less, you can get special LEDs thst have an integrated resistor from DigiKey or similar vendors. If you look carefully inside the lens you can see a small black speck on the top of the anode wireform. That black speck is the integrated resistor, chosen for safe operation at 5V. I'm not sure how much lower, but at 3.3V you can still see it illuminated. Not sure if the integrated resistor is enough current limiting at the 9V this video is using. Among the sizes they come in is 0.1" pitch. I find these small ones useful on proto boards like Arduino. Hold one I/O pin low and toggle an adjacent I/O appropriately for quick and simple diagnostics. (I first discovered them at a place I worked that used them to keep the BOM count down.)

Thanks for your comment. It may just be me, but I prefer to select my own resistor size and know exactly what's going on. It's a control thing 😁

@Sembazuru 11 ай бұрын

@@paulpkae That's fair. I was just letting you and other people know that those things exist. Your use of resistor networks for LED current limiting is a good pointer for others. Resistor networks are also very useful in digital circuits. If one needs to provide either pull-down or pull-up resistors for a data or address buss they come in really handy. For your audience, it should be said that there are two common types of resistor networks. The type you demonstrated are "Bussed", meaning all the resistors share a common pin. There are also is "Isolated" where none of the resistors in the package are connected. (Those are filter terms to use on sites like DigiKey when ordering them.)

@paulpkae 11 ай бұрын

@@Sembazuruy thanks again, your comments and sharing knowledge is very much welcomed; handy to know there are Bussed and Isolated types. I recall resistor packs being used on old style "MFM" HDD's back in the 80s to terminate the data chain. You had to remember to fit one to the last drive in the ribbon cable to prevent help alleviate signal reflections.

Generally, I’ve found using 600mil DIP IC packages with these types of breadboards problematic with so many pins wasted under the DIP package. Back in the day 40+ years ago, this style of breadboard was unaffordable to enthusiasts. Thanks for your insights.

instead of using specialized jumper wire, im just using wires from stripped scrap wire

@strenter 11 ай бұрын

0:30 Wouldn't it be nice if you could part it horizontally in the middle (maybe adding stripes of different widths) so you could add say a RasPi Pico to the board and still have four holes you could use for connecting on each side of the Pico? Just a thought...

I hold all my jumper wires in the same place. There is M-M, F-F, M-F and it is hard finding the type I want, I looked if there are different colored 'black housing(the ones at each end of the wire) to buy, that would have been helpful to just look for a green housing at the tip for M-M(ex)(3 colors for each type M-M, F-F, M-F ). I thought to try to color them myself, markers don't look good on black. Metallic paints scratch out. Another idea is to color code a small part of the wires above the black housing. I tried markers they don't look good, and I stopped.(other thoughts: metallic paint may flake off if wire is bent?)(maybe using paper tape? but it may come loose?) Either one big stripe of different colors on the wire, or same color but in segments(1 line M-M; 2 lines F-F; 3 lines M-F)

@paulpkae 11 ай бұрын

Wow. Your pushing "organising" well beyond what I have done. I'm not too fussed about the wire colours, but I do try to keep Black for GND, Red for +V and sometimes I match the colour coding of my four channel scope. For example, I might use channel one, which is Yellow, to monitor an input and channel two, which is blue, to monitor an output stage.

@@paulpkae I meant, is hard finding for example Female-Female wire in a pile of Male-Male, Female-Female, Male-Female, I pick one, wrong one(Male-Male), I pick another one, wrong one(Female-Female), etc. If they had the little black rectangle housing(the one that slides on the little metal connector that are at the the tips of the wire, not the wire color itself) at the tips of the wires with different colors, example: Male-Male = green housing (on both sides) Female-Female = yellow housing (on both sides) Male-Female = black housing (on both sides) In that pile of breadboard wires, I could just look at either side of the connector that has yellow housing, and that will be what I was looking for, Female-Female. (if I would want red wire female-female, I would look for yellow housing connector with red wire) (If I would want black male-male wire, I would look for green housing connector with black wire)

Thanks, that is a good idea. I will try on the wire above the connector, I think if I put it on the connector it will make it thicker and I think it may not fit when connecting the wires side by side on the breadboard.

No you DON'T throw it in the bin.... Use the flimsy Amazon jumpers as permanent, soldered links. I hate idiots that just throw shit away, because they can't be bothered to repurpose. And anyway, why bother to buy the link kits? Just get yourself some 22-23AWG tinned wire (1/4W resistor lead gauge) and slide over some coloured insulation (from recycled wire), then cut and bend to length. Note: I quite often retain a small compartment for naked (tinned) wire offcuts - from resistors. Even better - Guitar string offcuts make very robust breadboard jumpers and can be bent tight (90deg ends) and rigid; again, with a length of coloured insulation or small gauge heatshrink. Guitar string offcuts can also be cleanly bent into a curve, making for a very neat circuit layout; if a link needs to be robust, but pliable; say as a frequently used test probe, or hook-up, then *wound* guitar string offcuts work very well and will spring back into place after use; an added advantage of a light 'wound' string means for a more secure 'grip' within the female connectors of the breadboard matrix, due to the helical outer winding. Guitar string offcuts also work well for vertical stand-offs to a mounted daughter board etc... The make for neat bus connections too. Properly tinned, guitar string cores can also be soldered easily due to being largely nickel-steel alloy. Tip: Meaning that snapped strings (above the nut) can be repaired, by joining with a double slip or Lover's Knot and soldered across the knot, giving your string extra time on the fretboard, esp when times are lean. I NEVER throw away old guitar strings for this very reason. Finally - Amazon should be boycotted. I don't go anywhere near it. Not one of my pennies are going into Bezo's wallet.

Thanks for your comment. Don't worry, I'm not throwing anything away and already had in mind to utilise them for permanent boards as you suggest. Still remains a disappointing product though and another lesson learnt. Hopefully by sharing my experience it will help others make a more informed decision on what to buy. As for Amazon, I really like the convenience and given there's no electronics stores left on the high street in the UK, there's little option but to buy online these days.
