Hi all,
My light box is pretty much complete. I have to say I'm rather pleased with myself considering I'm a gumby when it comes to electronics; I managed to wire everything up by myself and hook it up to a diode and light switch and battery terminal.
Image 1: the final wiring layout. I have used 8 7000 mcd white LEDs wired in parallel (4 x 1 resistor + 2 LEDs). I am sure, that with a bit more careful planning, I could have cut out precise lengths of wire to make it even neater. I have used Tarzan Grip to glue all the components and have placed masking tape over the bits and pieces until the glue dries. I might just leave the tape on for extra security. The diode is right in the middle;
Image 2: lights on! You may notice that I've positioned the LEDs at approximately 45 degrees to point towards the centre of the first diffuser mask;
Image 3: on the outside, the battery holder and switch;
Image 4: a wider view to show where the battery holder and light switch are positioned;
Image 5: the box will double-up as a modern furniture/lighting featurette.
You can see how well the first and second diffuser work to stop light in its tracks;
Image 6: an evenly illuminated field!
Three things left to do:
1. Connect the LED panel correctly (much like the rest of the box -- with nails);
2. Create a front panel mask for my ED80;
3. Flock the exterior of the box with some kind of thick material so as to not blind star party goers or destroy their dark adaption.
I was going to spray paint the whole box in matte black, but, I kind of like the idea of having the box illuminate my bedsit at night -- it really is quite bright!
I am really tired right now, but, will hook up my ED80 to my camera tomorrow and take a series of flat fields and create a master flat field to see how this puppy performs.
I would love comments, criticism and/or ways to make this even better.
Thanks!
Regards,
Humayun
