I was going to ask that, but for me it doesn&#x27;t have to be a PC. We work on pretty low power electronics at work, but it is very hard to figure out what the best combination for practical hobby electronics would be. So like what kind of MCU, radio and display would consume the lowest power while still practical enough for me to have fun with. That would mean the MCU has to be 10+ mhz and the display needs to be at least file of a smaller smartphone. eInk would work.<p>It could be combined right? Very tiny low power lithium ion with inductive loading in some way that is efficient and easy enough.
