Ohhh, takes me back to when I was a little nerdling! I built a neon fireplace with big wax-paper capacitors (spray-painted brown) as the logs, and then made and painted up a cardboard-and-plaster mantel. There were a couple of 45V telephone batteries in the base. Used that for a few years, then the caps started to fail and the batteries started to be hard to come by, and I was headed off to college anyway. The orange of the neaon made for nice flickering flames. Happy 2021, and good riddance 2020!

Fran, a few things about the soldering issues you raised in this video: - You need more heat transfer and more wattage because of those big heatsink bus bars. You can pick up the classic Weller soldering guns (e.g. the classic D550) for less than $50 in any hardware store or online, and it will make quick work of these heavy solder joints. An electronics soldering station is outclassed by this situation. - You have minimal thermal contact between heat source and object to be raised to soldering temperature; the rounded iron tip touching the round bus bar at a single small point; this is worse than the normal situation of soldering a component lead to a PCB pad, which the iron and its tip are designed for. Holding the iron's tip at a flatter angle so more of the side of the tip lays parallel-ish to the plane of bus bar will help. - Moving the iron all around while trying to solder such heavy joints only makes it more difficult to achieve good thermal transfer. Keep the tip in once place and only move it a bit if you see a way to maximize surface contact area. - To improve thermal transfer, you can try to flood the area between tip and bus bar with a big ball of solder, but this is not an ideal way to do it; should be avoided if the other techniques do the trick.

The biggest issue that strikes me is that she is not making a proper mechanical connection before soldering. Seeing how the legs of the resistors meet each other and the uprights at 90° angle the wires of the components could easily have been one side j-hooked. She did it at 7:32 when soldering the 820k bleeders to the legs of the electrolytics. Why not follow thru?

I remember making a “neon blinky” (5 neon bulbs) from an old Radio Shack kit (back when there WAS a Radio Shack - ahem). It used a one or two transistor oscillator and a step-up transformer to create about 120-180 VDC from the secondary with a half-wave rectifier diode. The instructions included two variants you could make with the parts included; either a “random” or “sequential” blinky. I wish I had kept it, and the instructions. 🥺 This one though, looks much more cool; though the solder connections make me cringe 😬. Pre-tinning the leads definitely helps with this point-to-point, “dead bug” style of wiring. Oh well, as long as it works. 😊

I remember neon blinkies. If you add a metric crapload of capacitors between every neon then the flashing will always repeat in order instead of random, but too many capacitors are needed for more than 3 neons. So now it's much easier to clock a 4017 chip with a 555 and connect it to 10 LEDs.

Cool, Fran! Your power supply is a little overkill. Half-wave Dc would work fine so you did not need the filter caps. I've made 2 of those in my life. At age 9, from the Radio Shack kit in the red and clear box that ran from a 9v battery and used an oscillator and transformer to get the voltage it needed. Took it on vacation and left in the back window of the car one afternoon. It twisted in the heat but continued to work. The second, the last day of Junior College sitting bored in the lab. That one was mains powered and hung in my room blinking for about 5 years before the antique NE2 bulbs conked out. I "etched" the circuit board with a dremel, and left a fragment of copper, so on first try, it BANGed!. Replaced the main diode and it worked. Neither were as artful as yours.

I used speaker wire to tie the leads to the uprights on my project simular to that. Then I used a micro torch to get things hot enough for the solder to work. That calculator was the same exact type I was given in high school and told I would never amount to anything because I couldn't see math in my head. Back then, calculators in class was considered cheating. No one was allowed one. My how things have changed! My dad used to have boxes of old neon tubes and the large foil type resisters and what not. I loved making little projects back then. I ended up taking a short wave radio class in high school and got my licence. Funny how THAT happened being I was a math dummy.

Try aiming a laser diode onto one lamp, it will change blink rate to faster, as the laser light helps ionise the gas fill. Just have to use a shorter wavelength than neon emits, so a red laser diode will work, but a diode nearer IR will not. You can also use a valve output transformer on the common rail, only feeding the neon current through it, to drive a speaker and get an audio accompaniment of the flashing. Has to be a valve output transformer, any power rating, because regular AC transformers tend not to like DC in the primary, though 100V line transformers will work well enough for this, even with a closed core. Not going to be loud, but will have most of the switching spikes still come through.
@theskett
3 жыл бұрын
Upthread, Mike's Electric Stuff suggests using piezo disks (one in parallel with each neon, presumably) to get some timely clicking. Kinda annoying though, I suspect, because of multiple large-ish disks. Re using a transformer and speaker, Fran's caps are charging (in total) in the low-milliamps range -- so any not-tiny transformer should be fine with that much DC. But I don't see how you trivially get the neon switching currents through the transformer, given that the 'big' current spikes are only through the pairs of neons and caps -- sounds like a major re-wire?

Or think of it this way: To have 4 forward drops you need to connect 4 diodes in series, always connecting anodes to cathodes.

I remember my granddad coming home from a "Military Dispersal Sale" with boxes of all manner of surplus electronic stores, including bags, and I do mean bags, of neons. There was at least one case of 90v radio HT batteries, and heaps of resistors and capacitors amongst all the other stuff that he'd bought. I asked what he was going to do with all this stuff, and he said "We'll see". He grabbed a bag of those neons and a big 'mitt' full of Rs & Cs, then proceeded to assemble something similar to Fran's display, then he said, "Fetch one of those radio batteries" and connected a couple of these 'neon blinker' circuits, and hey presto! Then he drew out his schematic (which consisted of one neon, one capacitor and one resistor for each circuit) and said "Now, you set on and make me a bunch of those, and then we'll have a play with 'em". What a tedious job that was, but after making about a hundred of them, we fitted them into the lid of a wooden box (cigar box or some such) so that the neons poked through, and the 'tronics were hidden below. Add a 90v battery, and this thing began to blink like one of those "Burrough's Computers" from Lost In Space. I asked just how long a battery would last, and that's when he said again "We'll see" - I don't think we ever did see. That thing just kept on blinking until it became a forgotten artefact of Granddad's Bench. Beautifully simple, ridiculously low power consumption, and something of a novelty - At a time when so-called "Executive Toys" were becoming popular, Granddad's blinker was head and shoulders above swinging chrome dolphins, or Newton's Cradle etc! - This was the late '60s, or maybe early '70s.

Also I envy your Texas calculator. I happened to have one myself in the 70-ths, but it was too greedy for batteries, so I bought a Canon F-44 LCD one, that served for all years until 2020. It was so clever buttoned, with an exclusive PI button, and all other seccond function were the inverse of itself. Just what I needed. My current scientific one is incomprehensible stupid, by ridiculous buttoning. It takes me ethernities, to find for example PI as an inverse of A EXP. Others are hidden behind statistics, and other junk, where Excel and such are the first choice. Nostalgics say: "It was better before", and agree. Analog is funnier than digital.

Just did something similar for a New year's Rube Goldberg Junkyard Wars competition. High voltage capacitor, multii-megohm resistor as a bleeder, an n-channel MosFET and a relay. Works a treat!

Ha! It kinda looks like a cylon brain from the old Battlestar Galactica. I still love a good Larson scanner...

The neon bulb internal resistance when lit is very low or even negative. That means the flashes are short and changing the capacitor values do not noticeably change the flash duration. If anything, the brightness would be affected by the capacitor value. The period on the other hand is determined by the RC values of the charging circuit, as at that time the neon bulb resistance is nearly infinite. If you want to try extending the flash duration, you could try some relatively low value resistors directly in series with the neon bulb. I don't know if a 1k resistance would be good. It could be a starting point anyway.

The relaxation oscillator I built in junior high had two NE-2 bulbs and would up as the eyes of a plastic dinosaur.. i ran it on 14 9 volt batteries wired in series... This is a cool video!

Fran, love your builds, reminds me of so many investigation I did with the parts I had have around my work shop. Just loved this mains project, rc time delays escape allot of the arduino kids. I used to use this so discharge idea with relays using one side to switch what ever, the other to short the ramp charged condenser that relaxed the relay -- sound action attraction. Thank you for the fun

Tinsel as a conductor could be interesting. I think most of what’s sold is metalised polymer

Loving this tree And great to hear about the billing And most of all great to learn how this oscillation works cuz at first I didn't get it at all, how a cap could oscillate a light but now I have both learned this and finally understand neon bulbs. You're great, and all the best for the new year and many more.

Built with neon lights a while ago. Discovered that they glow differently depending on the polarity when using DC. If you have those that shine poorly, try to reverse them.

I saw this video again recently and I am remember a little circuit I made to sit on a table that had a NE555 oscillator driving a red green led. A variable resistor adjusted the duty cycle and a switch changed between a large cap and a small cap. With the large cap it went slowly from red to green and with the small cap it appeared to fade from red to green wit the duty cycle adjustment.

so parelel and series resisters added , when you are short on cash you can make this work I did the same when I was 14, I like the old components being used in this, I wish something could be used into like a bake off like what can you make off these old elec components like a traffic light system....

You could've just used an Arduino and some LEDs. Just kidding, this is Frantastic! I've thought about making some neon oscillators before but hadn't thought of adding the capacitors between rows. That really makes the effect so much better.

When I was at UW Platteville one class was taught nodal analysis, so built a 555 timer blinking light along the same open wire circuit, it ran 3 months continues

It's lovely. I want one! The only thing i would have done differently is too make a notch in the uprights where the components attach to make those joints a tiny bit cleaner and maybe solder better.

Pretty sure the g in härliga is the soft swedish g which is pronounced like the english y in yellow. No big deal.

Awesome build ! I've been trying to design similar stuff but with transistors for some years... and hopefully more functional :-D
