Light Mod's

Postby nativ » Tue Apr 10, 2012 11:29 am

just thinking about brightening up the ST........

or a thicker http://www.ebay.co.uk/itm/1M-Flexible-N ... 016wt_1165

Apparently you need a power inverter? but it will run off 2 AA batteries! Can a power source be found on the ST?

Thanks

The ST PSU delivers +12 and +5V DC, so you could just get an inverter like this: http://www.ebay.co.uk/itm/Tiny-Water-Re ... 256f538f6f and hook it up to the 12V rail i guess. EL wire doesn't take much juice so i THINK it should not overload the PSU. However you should be very careful because those drivers generate quite some electromagnetic interference and also audible noise. The EMI could be avoided by shielding it (if it's needed) and the noise can be reduced (but not eliminated) by some sort of padding.

Otherwise you could just go for LED's or CCFL's (CCFL's needs drivers too but i don't think they generate as much EMI or any audible noise).

Are these things conductive?
Would be nice to run them inside the case so a blue glow creeps out of the slanted cheese grater.

These just plug right into the power.

Or a knight rider 80's look?

Will have to get some and see what voltage is sufficient to drive them, don't think the inverter is entirely necessary?

I already have red led light coming from the HxC floppy emulator.
But it does not move from left to right :mrgreen:
Kind of lope sided as it's at the floppy drive area.

Yeah, but they're really expensive if you're just out for the LEDs though. I used to order LEDs from besthongkong.com but i guess ebay sellers have some cheap LEDs too. They just go to the power (through a resistor) no need for inverter.

EL stripes and CCFL tubes needs inverters to generate very high frequency AC about 1000hz+ or so.


I think i have a bunch of bright blue LEDs with resistors ready to hook up to 5V lying around :) Could send you some for free, i'll test them if you're interested.

So it seems that LED are easier to add than EL.
May be I will look for some cheap blue LED at ebay.

It's OK, I am not in Europe but Asia. Postage will be high.
May be Native will have some.

I fly RC airplanes and we use these LED strips on the delta wings. They are ultra bright and don't drain much power from the flight pack. They are available in many colours and very cheap. They are sold in meter strips and can be cut to whatever size you require. There are power solder points at intervals along the strip to enable mid point powering.

http://www.giantcod.co.uk/high-density-flexible-stripblue-1mtr-p-404321.html

To be honest I ordered 5 of the white strips with the intention of lighting up my hobby room, and all this from a 6-12 volt battery. Oh yes, they don't require resistors as they are surface mounted on the strip. The reverse side is sticky and with M3 tape and can be fixed to most surfaces. Could have potential for the Atari world, making it brighter one LED at at time, lol.

These are brighter than mormal LED ?
They an use the 12V from the PSU ?

They are ultrabright and use up to 12v. They can easily be connected to any power supply via soldering the 2 contact points. I had them connected to a 6v PSU and they were a little dimmer than when I connected them to a 12v PSU.

This looks great. I will see if eBay or a source nearer to me has some.

Heres a couple of shots I took earlier, just to show them light up using a 9v battery.
