acrylic front backlighting for Midibox SID V2?

Recommended Posts

I'm making a trio MIDIbox SID v2's with friends..

I noticed two of the acrylic panels I ordered can be backlighted.. normally color is black with gold lettering, but when backlit the gold turns into super cool spacey green..

I've been thinking of backlighting it and I'd love some suggestions.

What should I use, etc.. I've been thinking of 2 things: ultrabright LEDS on the inside (dont like the idea) or EL-FOIL glued to the underside of the panel (Like it very much, though expensive I think, not sure how to apply it)

Any suggestions?

pics (sorry, my camera is broken, the best i can do atm)

i can imagine backlighting the whole front will be a pain with LEDs, it's already a pain to make the control surface, it's a complete pain if i add a whole bunch of leds onderneath it.

the EL FOIL however becomes less bright over time.. i think it'll last ten years?

EL tape is pretty cheap me thinks... not as bright as a ton of LED's, but a lot easier to apply.

You could look at a fibre optic solution, use lots of plastic fibres to bring the light to the areas you want, then at least your light source (Led's or even lamps which are way cooler) can be in one spot.

I've been wanting to do this with my sid as well. I was planning on using a cold cathode light like the ones used in computer cases. They are cheap, run on 12v and usually have adjustable brightness. I have one that I salvaged recently and it even has a mic so it can light up with the music. Only drawback is that they use an inverter and that might introduce some noise into the audio but I think that all depends on placement besides, that problem exists with using EL stuff.

yeah, the inverters can be noisy themselves, the inverter in my sequencer drives me crazy sometimes.. i heard you have to somehow acoustically contain them and that there are special foam-sprays that do just that.

What I haven't really thought about, is that the original C64 psu might not be sufficient for some options

I'm still looking around, I have some white leds coming in soon so I can test how the light spreads

I am curious how deep are your panels cut to do the lighting from behind? Is there a terminology for this type of panel marking/engraving? From what your saying, did you just get a panel cut that was black with gold text and you put a white light underneath the panel and you got light up green text? Would a particular metal work the best for light to leak through?

In was looking up some perf board and came across this site

http://www.allelectronics.com/make-a-store/category/213/Electroluminescent-Strips/1.html

with some used el lighting for only $1 US each.They light up green already. Would this change the color scheme when used with you gold text do you think? They have new ones for $3.50 and $4.50 plus discounts on bigger orders. Can this stuff be cut and soldered back together to get longer lenghts?

Metals are usually opaque... and he has "acrylic" in the title  ;)

I don't really know of other plastics you would use for panels but it would depend on the material's refractive index, thickness and colour. It's hard to tell from his pictures, but it may be "smokey" acrylic which would transmit some light.

Because the yellow/gold letters are turning green, it actually means they are absorbing RED light and this lets the remaining GREEN light pass through. So using green backlights will probably work differently.

My Moog Voyager has a backlit panel  8), and with the intensity turned all the way up it hums pretty badly. Thankfully it doesn't get into the audio, but there is the possibility it might for these sorts of things, as someone said.

thanks.. some quick ebaying and googling revealed a flexible adhesive SMD variant of those led strips

the smaller the better .. on the same site http://sunlighting-led.com/productshow.asp?ArticleID=5PRX610VRX

meanwhile, i spoofed some more pics with the broken cam and bicycle lighting:

I think it might look really nice (can't say exactly, as the pictures are leaving things a bit to my imagination), reminds me a bit of the old (70's?) calculator displays (with those bright green characters) and some other electronics like on the picture..

@Flying Panther

your image shows exactly what i'm trying to get!

i've been looking into those LED strips, seems like a good solution.

prices vary a lot though, and china is tempting at the moment.

just saw this:

http://cgi.benl.ebay.be/5M-SMD-LED-Leiste-Strip-selbstklebend-300-SMDs-weiss-NEU_W0QQitemZ280363723930QQcmdZViewItemQQptZDE_Haus_Garten_Lampen_Licht_Leuchten?hash=item4146faec9a#ht_3842wt_2098

46 euro for a 5m strip with 300 leds on it.

width: 4mm

now i don't need that much, maybe if someone else is interested in half of it?

I noticed two of the acrylic panels I ordered ...

If I may ask, where did you get your acrylic front panels from, and how much did they cost?

I see Wilba [Edit: everyone :) ] uses Ponoko, and the results are quite nice, but I can't tell how much it would cost for one or two individual panels. [Edit: I can see the prices for the materials, but I don't have a sense of how much time it costs to laser-engrave/cut a complex design--they seem to charge per minute the engraver is running.]
