I was thinking along the lines of:
- Very small desk footprint But not once the laptop brick and its cables are taken into account.
- Powered from laptop power brick OK, but if the user only has one laptop and wants to use it at the same time as the PSU?
Also, consider the variation in types of laptop power connectors.
- Single output with CV and CC OK
- 0-12V at 0-2A or so OK
- Switching pre-reg and 'classical' analogue front end Two stages of regulation seems to add complication and cost
- Small screen (possibly OLED) and rotary encoders for V-set and I-set Novel, interesting
- Ability to stack units together to more outputs (and split supply) If the individual supplies are to be indepandant, to give say +/- 12volts, you will need isolation from the the common supply from the brick.
- Be very cheap for hobbyist/educational use Define "very cheap"
