3
* Pressing On-button must switch 240V line
4
5
** Battery driven?
6
*** Will there be an plumbum battery or only regular powersupply
7
** A simple 1,5V Alkali will do.
8
** -Button can handle 240V-
9 2 Maximilian Seesslen
** An 18650 is perfect. Along with the MCP73871 or only MAX1811ESA+. No integrated LDO necessary, only SSR is switched. AUR9811DGD only 33 Cents.

** An 18650 is way too big. We only flash the LED for a short time. Ne Knopfzelle wuerde es tun.

* Single-Button can be realised by bringing signal to mosfet along with diodes
13
* Simple STM32F042 can be used
14
* Mini-USB connector for direct charge.
15 5 Maximilian Seesslen
* 5V AC/DC Wandler integrieren; 5W, >80% efficienty; Keine Schnelladestation, nur effiziente powerline.
16 6 Maximilian Seesslen
* Strom messen (Step 2); STM32-32K-Variante sinnvoll; sinnvoller wie Akku messen der eh bestromt wird wenn geraet eingeschalten ist.
