Hey guys, newbie to the forum,
For my A level Product Design project I am designing a portable music stand with a built in lamp,
I need some help getting some good LEDs and the right circuitry into the little lamp in the space i have, and fairly quickly cos i am running out of time to make it, this is the last part i haven't yet made.
The size i have got to play with is the shape of that little symbol in your car that represents the front windscreen if you know what i mean, it's about 110mmx80mm and can be as deep as i need to accommodate the components, up to about 25mm.
I want to incorporate two rows of LEDs good enough to light the whole page of music, about 8 LEDS in both rows. I would also like a dimmer/variable resistor and an on off switch unless that comes in the dimmer. then i have space for a battery but not quite enough space for a 9v PP3 type. Then i have to worry about wiring it together or weather to use a breadboard type thing, so i thought i should ask you guys
if anyone can help me that will be brilliant, i am in midlands UK
If you can direct me to where to get the parts from, i would rather not go to maplins cos they have robbed a few of my mates recently
So to recap my circuit needs 2 rows of 6-10 LEDS (high power for lighting rather than signal type), a battery (ideally a replaceable one rather than an obscure super lithium deely that you can't buy from tesco), an on off switch and ideally a variable resistor, if not just a normal one.
I like the idea of being able to control the brightness cos with this project different environments need different lighting.
Thanks!
