Back in December 2013 I created a capacitive touch LED lamp to bring as a gift for a White Elephant holiday party. Since the event, I've gotten a few requests to build more of these to sell.
While I typically don't mass produce objects, I am in need to raise money to help fund a trip to China this summer, where I'll be speaking at an international 3D Printing Conference. My plan is to build and sell a limited run of lamps to help pay for my travel expenses.
The original lamp was wired by hand on a solder bread board, and used a voltage regulator salvaged from a car phone charger. While it worked great for a one-off unit, it would become quite tedious to build more than a few lamp circuits using this method.
For the limited run, I have re-designed this circuit to be produced as a home-etched printed circuit board. The toner resist transfer image (pictured above) was designed in Fritzing PCB Editor.
I etched, populated and soldered the first board to check and test the circuit. It works perfectly! The next step will be re-designing the lamp enclosure. These will go up for sale in May - so keep your eyes peeled for more updates!
