Making a ring light
Today I made a aluminium ring serving as heatsink for the ring light.
As I had to do it by hand, using only a hacksaw, dril and Dremel, I'v choosen to quick and dirty make a octagon shaped plate.
To be honest in the end it was more dirty than quick 
.
First I calculated:
and drew the shape on a piece of 2mm thick aluminium plate:
Then using hacksaw and Dremel, I cut it out:
Finally I drilled the holes for mounting the LED's and mounted them:
Thats it for now, next step, soldering and testing with the TPS9251 hopefully on Monday.
stay tuned.
