===== About =====
See [[hardware:lightDimmer]] for more information about the dimmer project.
This version is a rebuild of the previous one which is intended to be more secure and also cheaper if possible. This version has over-current/short-circuit protection.\\ 

===== Hardware =====
{{:hardware:lightdimmer30.jpg?320|First prototype}} Prototype v1. Works, but need to dimension the short-circuit parts.\\

===== Schematics =====
{{:hardware:svnimages:dm-igbt-rectified-v1.sch.png?320|Prototype 1 Schematic - short circut protection}} Prototype 1 Schematic, with short-cut protection.

{{:hardware:svnimages:dm-igbt-rectified-v2.sch.png?320|Prototype 1 Schematic}} Prototype 1 Schematic, without short-cut protection. D2, R2, C2 slows down the fall time of the IGBT to prevent noise and R.F.I.

===== Firmware =====
The firmware is written in Microchip's C18 V 3.16 using MPLAB 8.00. 

===== Downloads =====
