    Just received 50 TIP31C's from Jameco.com ($0.39 ea) Working on the individual boards now.

    Still thinking about how to layout the main board that holds the 595's

    Looks like I'm late to the game. If you don't mind SMD, checkout the IRLML6344TRPbF. Vgs(th) of only 0.8v, Rds(on) of 29mOhm @ 4.5V, and only 12.4 cents each in qty100 from Mouser. I'm driving them with 3.3V in my 18 channel wireless strip driver (WSD18). They stay nice and cool with 150ct strip, will test a 300ct soon:

    I started a design for the TLC5940 and a PNP (MPSA56 @ 11.3 per 100) driver, similar to your 595 project. I have my board layed out in Eagle but not finalized. I needed a max current 200mA per channel using mini-lamps.

    Wow cheap price for the tip31c. I paid a huge 1.15 each for the 6 I used for testing.
    You did well on those I think.
    How are the designs going.?
    I'm using PCB express for my design. Takes forever but worth the wait.
    80+ plus channels

    2 x 32 channel custom build tlc5940 dimmable DC controllers.
    1 ren 48 LSD v3c
    All rgb strips and 1 custom made face.

    Update:
    Decided to build everything on a couple of breadboards to begin with rather than try to build a bunch of PCB's. This will save a bunch of time and I can work on the PCB's for next year.

    Just received 6 more 5meter dumb RGB strips

    How much did your strips cost you. My last 2 were 18pounds each. Included a PSU and controller. ?

    Brilliant thanks for that. Do they have a wide solder pad or are they the real tiny ones. Magnifier required....

    You did want 3528 strips didn't you? Just noticed there were 3528's when most people use the 5050 strips. Just hope you're getting what you wanted.

    EDIT:
    Here's 3x 300 count 5050 5M strips:
