Make Your Schools Noticeboard REALLY Noticable

Make a boring old noticeboard really eye catching at a cheap price.

One day, I was sitting in class, doing my work (cough, cough, talking, cough) and my science teacher called me outside. Bugger, I thought. But no, he actually wanted me to build him something. WTF!? My teacher wants me to make him something? What is the world coming to! But he explained that the school had a spare noticeboard. So he snatched it and made it the grade 9 noticeboard. But it sits in a dark corner, never looked at...until Da_Fudge got hold of a soldering iron and his teachers money! YAY!!!!!!!!!!!!!!!!!!!!!!!!!!!!! So a quick trip to my nearest electronics supplier (Jaycar) got me a couple of neons, inverters, PSU's, a bunch of cable and a 555 flasher circuit.

Here I will show you how I did it, and hopefully win something in the 'Let It Glow' Contest!!! (Nudge Nudge, Wink Wink,)

Step 1: Parts

For this Project you will need:

2 x 300mm CCFL's
2 x 300mm CCFL inverters
1 x PSU capable of driving your neons
Misc Hardware

Optional: Flashing Circuitry
I used a 555 timer, 2 capacitors, 2 resistors, a diode and a relay.

Hey, just got a new camera. Do you think the macro function is working O.K?

Step 3: Construction

First, I decided to test CCFL's by themselves off a 12V SLA. My eyes still hurt. OK. So we know they work.

Next, I built up the flasher circuit. I meant to build it on breadboard, but I forgot to get some while I was at Jaycar. Dead Bug time!

Lay out your components in the position you will put them and solder the connections. Then hook up the little power harnesses that come with the inverters. Hook your neons to the inverter and fire it up.

Here is one of my tests.

kOOL DUDE I AM ALSO IN AUS and i also go to Jaycar, So which led rod is it exactly? And you could also go to Altronics, its really good store fro electronics

its a marque, not necessarily a noticeboard
Da_Fudge (author)  bumpus6 years ago
Oh. I'm in Australia and here we call 'em noticeboards.
Yeh they're called noticeboards in the UK too ;)
Yea

Cairns rules (well all of Australia rules but...)
i dont know where ur from but a marque is the sign above a theatre that scrolls through whats playing and whos in it.

i need something like this , i need a component that alternates power between 2 sets of led's what is the thing that switches the current called???
Da_Fudge (author)  =SMART=6 years ago
it's called a relay. If you want, PM me and i'll sent you a circuit diagram.
ohhh ok thanks im gonna go to the store and get one tommorow :D

good ible. was that your soldering iron in the picture though?
Da_Fudge (author)  tech-king6 years ago
Yep. I have that iron, should I say station. I just grabbed the picture of Duratech's website, because mine's pretty bashed up.
okay. i have a similar one. sadly, i dont have an pics of it already uploaded though. you can see it in the lower right of this picture though.

oh. looks identical to mine exept in black. where did you get yours? are you in australia?
nope, not in AU. i got it at my local supplier
Da_Fudge (author)  tech-king6 years ago
oh.
This looks really cool, but you should seriously consider using some transistors to avoid that clicking sound.
Yeah, thought about that but a) I had a binch of relays on hand b) It gives it 'Attitude' c) Like I said, the noticeboard lives in a dark corner of the school. The Clicking makes you turn your head and go "Oh sweet light....Hey! THere's school cricket on!" Thanks for the comment.
You're probably right. Nice job anyways.
thanks.

sorry. bunch, not binch.

Great to see your enthusiasm! Nice work - the notice board is now "more noticeable:))" Thank you!
Da_Fudge (author)  ej376 years ago
Thanks. Don't forget to vote if you like it! I've never won anything before, so it would be awesome if I could.
=SMART=6 years ago
very nice, maybe you could have used 4 different coloured Neon lights , or would that have cost too much??
Da_Fudge (author)  =SMART=6 years ago
Oh. I'm in Australia and here we call 'em noticeboards.
Da_Fudge (author)  Da_Fudge6 years ago
sorry. that comment was meant to be for bumpus. Umm, my teacher was on a bit of a budget, so he said make the most eyecatching, brightest display for under $55. $54.73 later, He had a sweet noticeboard.
