I don't actually
need a kit, just like I don't actually
need to learn electronics. I understand that I can learn a lot
if I design and build my own power supply from scratch; I'm just afraid that it's too big of a bite at once.
I could start with some dead simple design, and then learn more theory, iterate, and improve; but then it will take me a lot of time before I get something I feel would be useful and can move onto the next project.
I'm
hoping to find a kit that is versatile (i.e. good voltage and current range), well behaved (over-voltage protection, current limiting, overheat protection, no overshoot/spike at power on/off or when connecting a load), and complete (with enclosure and voltage/current meter). If I can find a kit like that, then I can build it and immediately have something working to power my next project. Eventually I can start designing my own power supply from scratch, but I don't want to do that today.
I don't mind marking, drilling, and cutting the enclosure. I can probably do that. It will be good practice. But if I have to pick my own enclosure and work out where to put the knobs, meters, sockets, etc on the front and back panels right away, that's another story.
In other words, it's not so much about my
need as it is about how much I would like to learn from this project, and what I want in the end product.
What I would like to learn from this project:
- practice soldering
- learn to read schematics
- basic hand crafting (the part where I mark, drill, and cut the enclosure)
Ideally, what I would like to get out of it as an end product, is a power supply that has:
- dual tracking
- at least 0-15 VDC per track
- at least 0-3A per track
- current limiting
- over voltage protection
- overheat protection
- no overshoot at power on/off or when connecting a load
- an enclosure
- voltage meters
- current meter (optional)
