These are a whole bunch of things to make with the 555 timer IC with a note for each picture.
I do not take credit for these schematics, they were made by Collin Mitchel.

As you would probably think it took me a very long time to make this but it was night and i was wanting to waste some time so i hope you like it!

I have descriptions for each and every picture so feel free to ask questions!

hallo i need to make an led signboard with as many led's as possible. probably 500. how can i drive the leds using 555 and 4017 without compromising on current. what would be the ideal voltage. reply pwamutitu@yahoo.com.

Oh man, if you want to drive MORE than 500 LEDs by 555 and 4017, you nedd REALLY MUCH soldering and contruction. Use MCU, its easier and you can take it what you want. But you probably will need multiplexer. Just use think called google.

Hello Guys, I am facing difficulty in finding good microphone for sound operated robot with 555, I purchased many mic. phones but its range is very. How could I amplify n improve its range? please suggest me the best one.

get a wireless mic and provide a receiver to the robot.

Thanks Colin,,, Awesome designs you have here!!!! Unfortunately the Designer of the 555 chip Hans Camerzind passed away Recently,,His Design of The 555 chip made it a Household Name!!! The 555 is still one of the most widely used I.C.chips in the history of I.C. electronics!!! Actually with all the circuits we have here I Don't know which one I want to Breadboard Here!!!
Colin, I recognized your drawings immediately and wanted to point out this author's source from which the drawings were shamelessly copied, then saw that you already did, and it seems that nobody cares... the dark side of open sharing I guess... at least the link you gave will expose your generously informative website to some new readers.

Actually I emailed him and asked permission to use these schematics which he allowed.

My name is Mike
I have a question or a favor for you maybe you can help me. Thanks in Advance
I am in the process of making a board game called shut the box it's a dice board game. I'm sure you have heard of it for my daughter. Instead of flipping wooden numbers I would like to use some type of ic numbers 1-9 that are fixed so all I have to do is push a button coresponing to the specific number to turn it on or off if you look at google images under shut the box to get a better idea of what im talking about. any help would be greatly appreciated you can email me at mag200181@gmail.com
thank you so much
Sir i need some helpful material for music box. Kindly provide how it works?? waiting for ur reply. smya_tripathi24@rediffmail.com

wow! this is one 555 timer instructable that I can really get behind!
I find that most of them are way too many describing how to do the same thing. but you have really done a neat thing putting all of these different projects together!

I like it.

I need help with coming up with a circuit or finding one that will operate a remote control car to 22 feet then cut off. If anyone have any ideas or can point me in the right direction it will be appreciated!!

Hi there, for the "Stun Gun", can I replace the 10nF capacitors for 100nF? these are the only ones I can get at 400V, also, can I replace the BD679 darlington for a TIP122?
Jimmy Proton (author)  aesquivel3 years ago
Im not sure the 100nF capacitors will make much of a difference and yeah that should work, it seems to be the same things but with higher ratings.
could you use 10nf with 500v?
yes why not!

please help! [nub]
at the tv remote Jammer project, the [5r6] is a 6 ohm resistor and 470r - 470 ohm R? and please...which is the transistor's code?
Jimmy Proton (author)  EdDruino3 years ago
The R just stands for resistance, so the number next to it is ohms. And there is no specific code for the transistor, I assume that you could just use any general purpose NPN transistor.
thnx for the quick reply!

Hey, awesome circuits! I got this pack of 3 555's and am looking for something cool to do with them.
By the way, do the "Police lights" with the two 555's act different from the one with a 555 and a 4017? I mean, do the lights flash any different? Because from what I know the one with the 4017 flashes fast 3 times on each side, back and forth. I have 3 555's, so if the circuit flashes the same, I'd like to use that one.
Thanks! Awesome instructable. Simple, but useful :D

Does anyone have an eagle file for the stun gun? this would be very helpful as i am new to schematic design
