LED module - 400lm

nobody@ipernity.com (.:madworm:.) — Thu, 20 Mar 2014 15:51:01 +0000

Upgraded version of a previous project. It essentially doubles the light output, same price. Newer kind of high-efficiency LEDs from Nichia. This module runs from 18-24V DC @ 180mA.

This one is just for the heck of it. I don't plan doing 0402 parts on a regular basis.

Once connected to power using conductive thread, this little thing (just 18mm diameter) will blink / fade its LEDs. Switching between modes is done by shorting the two marked pins before powering up the device.

The new RGB LED Ring v2 is powerful enough indeed.

Using the Arduino 'ShiftPWM' library (slightly adjusted) gives super-smooth fading effects.

LED - uniformity issues

Quite a few LEDs emit too much red. I will need some sort of dot correction to compensate ;-(

8 out of 10 boards have issues.

ATtiny13 LED-strip controller

Works acceptably for the first prototype. It certainly doesn't get warm at all. Further examination will need a scope.

One pot sets the desired brightness, the other one the fade-delay.

LED strip - brightness vs. position

There's a voltage drop of about 1V across the 5m strip. Too much resistance. Needs multiple power injections to compensate.

This was only for testing, it doesn't really make sense to have remote control here. I sit right in front of it.

TSOP-ed my kitchen lights

After replacing the 12V victim with another ATtiny85 and switching the IR sensor to the TSOP38238 (cheaper, better range and less directional), my kitchen lights are now under remote control. It only looks ugly from below. While doing things one does in a kitchen you hardly notice any of that.

Now if only I could embed these boards into the bottom of glasses... that would be nice.
