Anyone given thought to making their own RGBwW LED Light bul

I imagine the cost could be cut dramatically from the $65+ currently available versions cost.

I got the idea from surfing DX.com and saw they have empty shells available.

If it could be done for around $20 a bulb, then I would be able to retrofit the house in a really cool way. I’ve got a interesting house with a lot of bulbs on the first floor. 8 shy of 100.

My first problem, I haven't the clue where to start in trying to put the hardware etc together.

Give it some thought ;-)

- Wed Feb 11, 2015 9:34 am #9470 I'm actually making one right now. I have written some basic software to accept the UDP message from ESP, store them as individual nodes and send JSON messages back with a little comman line interface. I am now trying to approach the firmware writing bit and still debating about wether to use nodemcu or just start writing from scratch using the SDK.

As for the bulb itself, there's a nice little example http://spritesmods.com/?art=rgbledlamp to deal with the power issues etc. I haven't given it much thought though, I'll get the ESP to control an RGB LED on the breadboard and then figure the rest out.

Also same doubts as Richard said :)
