A project focused on giving an old, discarded ATX power supply a second life by converting it into a compact and functional lab bench power supply
hey there! this is super cool. I'm going to approve this project, but I would highly recommend including your parts inside your CAD model
make sure to post pics once this is done!!
Hi, hi!
Great work on this project! There are a few changes that need to be made with the BOM:
- Add a total! Make sure that you have a row with the grand total.
- Make sure that you are giving exact numbers! I highly recommend giving exact numbers (Ex. for your heatset inserts you would say $6.04 instead of ~$5 to make sure you have enough money)..
- You are missing your printing legion item! The shell of your project is going to be made on Printing Legion, assuming that you don't have a 3D Printer. Use #printing-legion to find a printer, and include their cost in the BOM.
Once these changes are made, we will take another look, and if everything is good, we will approve!
Have a nice day! :D
I think everything is ready to ship. I changed up a lot of things but i couldn’t record around 3 hours of it but that’s alright cause there were some recent hackatime issues.
Changed up the CAD and the whole BOM. I also added a 0-36V buck-boost converter for a variable voltage/current supply which I am pretty sure will be incredibly helpful with my bionic projects
Sourcing the CAD Files & Building the BOM
This stage was mostly about getting the physical side of RePSU figured out before moving further into the build.
I started by sourcing the CAD files for the enclosure and checking the different views to understand how everything would fit together. Having the enclosure laid out made it much easier to plan where the displays, banana sockets, buttons and other components would go.
Once the enclosure was taking shape, I started putting together the Bill of Materials (BOM). I went through each component needed for the build, recorded the quantity, found suitable parts, and added the approximate prices and purchase links. The current BOM includes the displays, banana sockets, fuses, buttons, fans, MOSFETs, and the 85W USB charger.
The estimated cost is around $35 USD, excluding the original ATX PSU and miscellaneous hardware.
This gives me a much clearer idea of what I actually need to source before starting the physical assembly.
