I got this desk for $200 untested and had it shipped from South Carolina to Baltimore for $100 through an app called uShip which is like an Uber for shipping. It looked like it had been sitting for a long time so I cleaned it up and looked over all the modules, nothing looks burnt or broken. These 1083 kits are only $15+$15 for the ones pictured and $11x4 for the smaller ones and I have a box of assorted toroids that a local factory threw out. I'll test the regulators under load that's good advice
Ohm's law.. what a thing.
lets see how many degrees C/W these heat sinks need to be. Whats the specific heat of aluminum? How many watts we talking?
Reasonable enough. Thanks for the heads up about uship, that looks like it could come in handy!
The power one HD15 6amp supplys are available for around 40$ used on Ebay all the time. They are properly designed, and have the heatsinks, so I think thats pretty hard to beat, once you factor in the cost of heatsinks I wonder how the cost will compare.
Ultimately dissipation and heatsink size will depend on what transformer you are using. Oh and if you want an evil fan in your power supply or not. ;D
