Retro Lamp goes HypnoOrb

Doc2 Comments

Candice saved this hideous old lamp from a bulldozer (literally) and for the last year and a bit we’ve had it hanging up in our basement for extra ambient lighting. The light was setup only to be turned off/on by pulling/placing the plug and that part’s so sketch that we rarely use the thing. So when it came time to replace a bulb, I decided to use a HypnoOrb instead of a more typical bulb.

Essentially what I did was very carefully solder wires on to the light socket and connected them to a power adapter. The power adapter was then connected in to one of my Arduino boards programmed with the HypnoOrb code, though slightly modified to respond a little nicer to the potentiometer input.

I of course had to also hook up an RGB LED to the whole deal and I goofed with that for awhile. I ultimately decided to try using this whole setup with no resistors on the LEDs.

Now, normally you should never do that as if you don’t limit the current through a diode with a resistor, you could (more like definitely will) burn out the LED. But I knew that for some reason with the Arduino that doesn’t seem to happen. Anyway, this time I opted to leave the resistor out for maximum brightness.

A couple of hours, some solder and a TON of hot glue later, It’s all come together rather perfectly. Bamboo Skewers were key in providing a little needed structure and of course much electrical tape and some soldering filled in the gaps. I also added a little off-on switch and latched on a potentiometer to set varying speeds of operation.

Here’s a video I decided to toss up on YouTube just showing some of the results of some of the goofing around I’ve been doing with my Arduino board (it’s actually a Freeduino).

I had a lot of trouble getting the board to work at first, but once I ran it through an ultrasonic cleaner it seemed to smooth out a lot. Though, some times it still has a hard time programming, in which case I can just apply pressure to the FTDI chip and then it’ll program. I’ve tried re-soldering the pins on the FTDI, but that didn’t entirely resolve the issue enough. Not to worry though, it consistently works perfectly enough for me.
