Do you remember the log Another ordering mistake ? Well...
I have a new indoor leafed companion and he feels very sad in the dark. He's used to a different climate with intense direct sunlight so he has a lot of troubles with growing :-(
So I took the "full spectrum" LED modules from the archives and made a crude power supply. The modules require about 28V but I didn't want to go full power so a dual single-wave rectifier transforms 12Vac (from a small wall transformer) into 26.6V (average). It's... very bright, though not overwhelming, which should be more than enough for my companion.
2 diodes, 2 bulk capacitors, some wires and connectors... that's it. For now.
The story is not over because I still need to solve a lot of practical issues, such as finding a long enough wire, or mount the LED module in the right height and position to target the leaves. Oh and some alu paper around the whole will reduce the waste of light, as well as keep me from waking up with the light :-D
And if you really want to know, it's a baobab coming straight from Africa... He has already lost his leaves several times (due to accidents) but keeps regrowing (slowly) so I want to give him a chance :-D
