Gee.. Me 65+ years. My first contact with them logic's was about in them mid-70's. There was allso something called 'DTL-logic', and ewen RTL-logic's, can you imagine that?. My first contact with a 'microcontroller' was a 1-bit data, 16-bit adress, (yes You read it right, one bit & 16 bit), and concidered as 'wery' powerful as a microcontroller, because it had 'built-in' them all functions, I/O, RAM, EPROM (but not with EEPROM or FLASH, they were not invented, yet).

    LED CHASER With IC555 and IC4017

    Hi. Your on "right" track with your ible. Howewer, take a TV-reciver: it displays , (in Finland), 2x25 frames, (overlapping each other), ower your screen, thus giving you a illusion of a movement. Same thing at Movie theatre, with 25 frames/second. So if you speed up yuor LED-display with 8 leds to a speed of ~50fr./sec./8 LEDS to lit in a sequence/second, with only 1 lit at a time. The speed for ewery individual LED would be 1sec./50/8 = ~10msec./LED. That would be a speed of 100Hrz. And that would make it to seem if they "ALL" were lit at the same time. Make that freq. to be in 10's of KHz ~ up to MHz and you could lit up thousends of LED-s in a seq. and still it looks like to be lit all at the same time. So, the speed is not a issue here

    Oh Boy! Take a look at the tech. spec. of a 4017, and You will find out that it’s capable of MHz with its output, (that's in a class of ”million’s”/second). BUT ”STILL” with ”ONLY 1” output active at a time, so that said.

    Actually: 1.) The frequency of the shift can go up to MHz, (MegaHerzts = millions of changes/second), still, "JUST ONE" bit active at a time, so that.2.) The human "brain" can't make a difference in of an eye seen thing with an alternating speed of more than 25 "frames"/second, (e.g. "The movies" play appr. 25-50 "still-pictures"/second). That's why there "seems" to be more than one LED's lit at the same time. Take a look at the tech. spec. of 4017

    I just "LOVE" the 555. I've done dozens of app's with it since early '80,s, (Yes, allmost 40 years ago). Your ible is wery nice for a beginner, it gives a "hum" of the functionality of the 555 and the digital side of functions with the 4017. However, because only one output of the 4017 is active at a time (HIGH), wouldn't it be smarter to have only 1 resistor common to all, (the cathode side)?

    You are so right. How "stupid of me"? I kind'a missed that with a booster. It's absolutely correct as You discribe it. 1 question: what kind of UV-led you used? UVA or UVB or could there be some pros. by using a "mix" of both. Gonna absolutely build one and "add" a timer there. For now I have a "555"/relay based timer for my 300W "Solar UVA" lamp, (yes, you read it right, three hundred Watt), :)

After developing, rince the PCB under such hot water You ewer can, thus making the PCB-copper to be warm. This decreases the etch time. 2. I use to clean the PCB from the resist ”before” drilling, and I’ll do that with ”technical pure aceton”, because the nail-polish-remover has oil in it, and that’s not so good.3. If You use ”acid” etching, put the PCB facing down in the bath, reason: in the reaction it creates gas-bubbles & lift’s up the board so the etch-side isn’t in the etchant. This method allso results in pro: them bubbles tend to move around the board a bit, thus giving ewently contact with the etchant.4. Making double sided ones. The main problem is to get them both sides aligned? Well, in Your layout-design make some guide-holes of a size ~ 0,8mm in the corners. On them ”both” film’s, punch holes in them guide markers with a needle, (of course You can use some of them component-holes if You don’t have guide-holes).Tape the first layout on the board, (say the solder side), drill them holes for them guide-holes , (use a small hole e.g. 0,8mm.) . Put drill bit’s in them holes, place the top layer film in place by using them drill bits to go through them punched needle-holes, and tape it in place, (remember to remove them bits before continuing  ).5. Now it comes to ”saw” the PCB to it’s actual size. I used to saw them PCB’s with a hacksaw with a ”pain…. pain…pain” never getting quite good reults, (allways had to file them to acchive good result). Until I read a instr. : ”Use a box-cutter knife & a metallic ruler, then make several cut’s on both sides along the same line, (if there’s copper where You’r cutting, make sure to cut at least through the copper), then just bend the PCB against ex. Your table edge, and ”crack”, (the noice, not the stuff)”, and voilá You got a nice cut-out .6. I’ve even made double sided PCB’s with another methode, with succes. I bought of them resistive board’s with a thicknes of 0,8mm. Made them separately as one sider’s. Keep in mind with this methode; the TOP-layer has to be ”mirrored”. My ”pcb-design” program allows this to be done. Then I drilled them both, (separately). Then ”sandwitched” them, no glue no nothing needed, just put some components in place and solder them. NOTE a con. here: this isn’t plated through, so, some component’s ”cower” them pad’s so You can’t solder them from the component side pad, thus not create connection with both sides. Allso remember Your ”via’s”.Your instr. Was GREAT 

    Hi. Niiiice job. Just some propose’s: I would rather make them pattern’s, (column’s), with 5 in each, thus gaining to use ½ of the Voltage e.g. instead of ~38V you need only 18V or use pattern’s of 3 = 3,3V*3= 9,9V and use a 12V power. Of course the layout would be a bit more complicated but not much, (just a couple more resistors and wiring). This allso gives you the benefit of need to drop the voltage just 12V - 9,9 = 2,1V with the resistors, and this way you get the poss. to use higher mA with less power loss.

    Hi. Actually I use use in my apps. them LED's to be limited to 10~15mA thus NOT giving the full brightnes, bu to raise from 15 => to 20mA wan't make the brightnes to increase noticebly. The wattage of the resistor is of a less matter, e.g. if needed voltage drop from the source to LED's (RED=2,0V), then with 9V: 9-2=7V ; 7V*0,02A = 0,35W thus a 1/2 Watt resistor will do the job.

    Actually You should start with black.... = 0 . Black isn't actually a colour at all.... black is black.. as they sing in them 60's, but there's a dilemma, Don't use the third ring as a multiplier, (black is zero multiplied with.... gives you zero), the third ring ONLY says how many zeros you put there.... after them 2 ring's, e.g. brown, brown, brown will make: 2, 2, +1 = 220 Note!

Haven't done this yet but, because it's so useless, anyway: a "Light-switch controller in my living/ working-room, to turn On-Off them lights there randomely. Why randomely? Mostly I don't know if I'm producting something usefull or not, who can tell? So, who cares if the light is "On" or "Off"?

    I'm an "oldy" 65+ years, took my first classes in TTL-logic's, (Transistor-Transistor-Logic, in them early 70's, (in those days there were allso logics called DTL, Diod-Transistor-Logic, and ewen RTL-logic, Resistor-Transistor-Logic). Gee.. then there came this "Revolutionary " 555... We were stunned??? What?? Can you do something like that with a "chip", ( a chip as a component, wasn't declared then yet), the chip actually became with the first microprosessor's. I bought my first "Microcontroller" in early 80's. It was 1byte, (yes, 1 byte in data), and 16byte adress, (yes 16bytes). And having a total of 6, (yes, 6), different commands. I just wonder, "could one create something totally useless of that in those days?" Gee.. they wenth t...

Gee.. they wenth to moon with less of 1Megabyte of microprocessor power, so it could actually be called for "totally" useless, (that is: so what?.. been to moon so what.?). Next step: Mars? useless?? naaah.. we, (the mankind), do really need these useless innovations, they'w showed to be be them of gratest innovations of all

    Yes, this is "really" amusing. But the "Main" question still remains:" Do I want the switch to stay "On" or "Off"?, So actually we have to ask the switch itself, rather to be "On" or "Off", I'll wait for the anserw from the switch, (of course you could build in some Artificeally Intelligence in the logics for the switch), but that would still be something that a person with he's own logic's put in there So, still the switch hasn't a mind of itself. So this is totally "useless" and fullfills them requirements of beein'g useless. Again Congrat's with a fine work, (gonna try to beat you :))

    Go MartinD_CZ Go.. Don't let them pessimist's turn out the incredible light of innovation. This forum "Instructables" is just for guy's like you and me. Let's make "something new", ...somebody in the 1700'th centure in UK, (was it UK in those days?), in the parliament said: "There's nothing more to innovate, the world has all the knowledge for a mankind need to know", and this was declared in the parliament of the Upper house. Hmmm????

    Arduino Nixie Tube Clock - Version 1.0

    Gee,, you got lost in some corner. Most, nearly ewery constuction, requires a separate power source eg. 12V, (with req. Amp's), besides of that your microcontroller board provides, (Arduino....some 100mAp's..total), But keep in mind: them GND, (0-volt, Zero.. or whatewer you call it), needs to be in the same potention, (with an diff. if you use analog and wanna keep that separated from the potentional's),

    If I was the bussinesman delievering these products, and found out that the demand is bigger than the capasity of delievre, I would force the production-line to acchive more.

    Just "LOVE" your ible. Actually they, (nixie-tubes), were the basics to what became them 7-segment displays. Them "youth" may not know about them "nixie-tubes" beeing actually "filaments" stacked vertically vs. 7-segment "just" to be flat

    OK. I'll take another lesson in english, (by watching another film on TV), if you promise me to take another session with your "shrink"

    *) my bad, it should read "Leonardo" not "Leanardo", please forgive me Leonardo.

    Yeah! Me a "total" fan of 555. Gee.. use the bigbrother to 555, 556, a dual 555, and make the other to be "random", that is: charge/discharge/the treshold of the other depending on the delay of your toggle of the switch... reset pin 4. on 555 :)And again: take the advantage of the recharge-pin #7LOVE your ible

    Right you are. It's useful by acchiveing the function of "not" to be usefull. Or vice versa. A'm I usefull by writing this comment?, guess not, still, someone reads my comment. Is that usefull or not?The Ible is Fantastic, (I'll try to come with a more useless something like ... to not "breath", it's not the intake but the outbreath which is the pollunitation of the enviroement. Phuuuh... if I don't reply to this then I succeeded with my "antibreathing"

    Gee.. ewerything that's useful is allready there for sale, BUT to create something that's NOT useful is kind of a skill of art to create something nobody else have done before. To create something "not usefull" takes as much of effort to create something useful... & vice versa

    There you go. Neither did them in those days living "average" people understand of them "innovators" creating totally useless things.

    Just a note for them not have used the 555. Take the advantage of the pin 7, recharge, it's an open collector output to recharge the cap/res for the treshold. It can be used the same way as the output pin 3, thus beeing active when it's time to recharge the cap

    You saved my day. Got a big, Fat, Good laugh. "This" is a real "BONK", useless thing, excellent. Once upon the time there were people saying: "This monster, a Automobile, what on earth do we need it for?", "for god's sake we have them horses". And then there was this Italian guy "Marconi", he disclaimed something stupid of to communicate electrically "wireless, (via Eter),". Then them "REALLY BIG guys from IBM said: "the whole WORLD will do with 6, (read: six), powerful computers, say: 100MHz/ 4bit pros./ .... ++++ many other's in those days concidered constuctors of "USELESS" machines to be stupid.How wrong were they???Trust me if I say that this your 555 inspires 1000's of people, because of it's reversed...

    World's Simplest Electric Train

    If you put them batterys in series you'll get battery1 + battery2 +battey3 = 1,5V +1,5V +1,5V gives you 4,5V Comprende? If you put put them parallel you got the accesibilty of that them Amps they can provide, still 1,5V in output

    Actually, the efficient "work" named "P" is as power in a factor in electricity, (and ower all), P=U*I, Hmm... to define "P" ..I think the "P" is about the same thing as lifting a weight of 1Kg from a niveau of 0 to 1meter in 1 second. Correct me if I'm wrong.As in electricity we allways talk about "Watt's and Amp's", Com'on "Watts" are the product, (Power), delievered by Volts*Amps, how hard can that be to understand, (not you).

    Hi! Me an old-timer making them PCB’s. I have made ”hundreds (100’s) of them, thus today still using the ”old golden system” 1+2+3 methode of 1= HCL (36%), 2= Hydroperoxid (25%), 3=Water (100%). The numbers in ( ) are the concentration of the stuff.For the developeing of the photoresistive I use NaHO, (Natrium Hydroxide).
