Maker Michael Woodrum has constructed a wood bar lamp, impressed by Greene and Greene, that is managed by way of MQTT messaging from a house automation setup.
“I wanted a lamp to suit a particular space,” Woodrum explains of the venture’s origins. “I wished to have the ability to management it with our residence automation system and I like making issues. The LED shouldn’t use power when set to off. To do that I embrace a relay in my circuit that cuts the ability to the LED output. With out this relay, a small quantity of power shall be used always.”

The center of the construct is a Wemos LOLIN D1 Mini board, that includes an Espressif ESP8266 microcontroller with on-board Wi-Fi connectivity. That is used to output a pulse-width modulated (PWM) sign to a TIP120 transistor — “to manage the ability to the LED that the pin itself can not deal with,” Woodrum explains — whereas energy for the LEDs is handed by way of a relay to stop “phantom energy draw” whereas the sunshine is meant to be off.
Designed in Fusion 360 and impressed by the architectural work of Greene and Greene, the agency based by brothers Charles Sumner and Henry Mather Greene in 1894 and finest recognized for its work on “final bungalow” housing, the lamp is constructed from walnut and cherry wooden and hung suspended from the ceiling utilizing metal cable.

“I identical to that utilizing my very own designs, I do know precisely what is going on,” Woodrum writes of his motive to not merely buy one thing off-the-shelf for his lighting wants. “To not point out, I’ve higher reliability with self-made lighting initiatives than buying [Philips] Hue lamps. They don’t final lengthy. Some do, some final 6 months and die.”
Woodrum’s full write-up, together with supply code, is now out there on Instructables.
