Mattwach, of the Matt’s Electronics & RC YouTube channel, has a chandelier that got here with the home that his household bought over 10 years in the past. Whereas it’s a pleasant piece, it’s positioned at a second story degree, shining principally upwards in order to offer oblique lighting. This additionally implies that a standard changer-on-a-pole received’t work, and who actually needs to pull an enormous ladder by way of the home and transfer tables and such round for entry?
An fascinating characteristic of this home in relation to the chandelier, is that there is a second story walkway that would present a superb vantage level for bulb modifications – if changer-poles labored at 90º. Matt designed simply such a tool, and although it’d sound like a joke about engineers and altering a light-weight bulb, as proven within the video under at in regards to the 29 minute mark, it really works fairly effectively! He was in a position to swap out the entire chandelier to extra environment friendly trendy bulbs utilizing it, saving a complete of roughly 825 watts of energy utilization.
The setup is kind of an adapter for a changer pole, including a motor that spins at 90º by way of 3D-printed components designed in OpenSCAD. Controls-wise, the changer makes use of an ATtiny85 microcontroller to soak up voltage alerts from a Ps-style analog stick, which it interprets into PWM and directional outputs which are despatched to an L293D motor driver. The code additionally features a rail velocity setting to maintain the motor from ramping up too rapidly, possible a good suggestion for this type of software.
