• で effevee 13/08/2017 This little 12V DC power supply is easy to build with few components and has a nice plexy case that holds everything. Nice is also the included transformer so you can power it with 220V AC. Only minor point of critic is that the screws for the standoffs to mount the circuit board into the case are a little bit too long and can't be tightened enough. Fortunately I had some shorter screws lying around. The output voltage is quite accurate. All by all good value for money :-)
• で SergioSilva 09/01/2018 It was a little fun to assemble the kit it came without any instructions but that wasn't a problem for me. It didn't came with all the screw needed but also not a problem because i had some laying around. The power cable has only 30cm so it's too short. I will replace it for a longer one. The acrylic case could be stronger the plates are too thin. Overall it's a good kit for the price it costs and kept me occupied for a few time.
