| 3 | 8 | Maximilian Seesslen | Everything should be completely shut off when I'm not at home. Even clocks, displays, sensors. |
| 4 | 12 | Maximilian Seesslen | In the end something like a bookrest, small wooden triangular bar. Or a Panel that can be lasered. |
| 5 | 8 | Maximilian Seesslen | |
| 6 | 1 | Maximilian Seesslen | * Pressing On-button must switch 240V line |
| 7 | |||
| 8 | ** Battery driven? |
||
| 9 | *** Will there be an plumbum battery or only regular powersupply |
||
| 10 | ** A simple 1,5V Alkali will do. |
||
| 11 | ** -Button can handle 240V- |
||
| 12 | 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. |
| 13 | 4 | Maximilian Seesslen | ** An 18650 is way too big. We only flash the LED for a short time. Ne Knopfzelle wuerde es tun. |
| 14 | 7 | Maximilian Seesslen | ** 2 AA-Alkali-batterien brauchen wieder Platz. So wenig stress wie die Knopfzelle im Miniminutnik macht. muesste ich wohl oefters die Industriezelle wechseln als die Knopfzelle. |
| 15 | 11 | Maximilian Seesslen | ** 2xAAA noch vertretbar. einfacher wechselbar wie die Knopfzelle. 1 Dauer-LED macht nicht laenger wie 8 Tage mit. Evtl. LED-Ring mitschalten damit man leere Batterien erkennt. |
| 16 | 1 | Maximilian Seesslen | |
| 17 | 7 | Maximilian Seesslen | * Single-Button can be realised by bringing signal to mosfet along with diodes. Dioden wegen Erhaltungsausgang. Zelle geht auf SSR, dann geht MCU-Ausgang auf SSR |
| 18 | 1 | Maximilian Seesslen | * Simple STM32F042 can be used |
| 19 | * Mini-USB connector for direct charge. |
||
| 20 | 13 | Maximilian Seesslen | * 5V AC/DC Wandler integrieren; 5W, >80% efficienty; Keine Schnelladestation, nur effiziente powerline. EME05 |
| 21 | 22 | Maximilian Seesslen | |
| 22 | 6 | Maximilian Seesslen | * Strom messen (Step 2); STM32-32K-Variante sinnvoll; sinnvoller wie Akku messen der eh bestromt wird wenn geraet eingeschalten ist. |
| 23 | 24 | Maximilian Seesslen | ** INA138NA/250; OP-Amp; verloeten kann man ihn ja mal. "Doc":https://www.ti.com/lit/ds/symlink/ina138.pdf |
| 24 | 21 | Maximilian Seesslen | *** Gain 20; RL=100K; Max Voltage at input: 3V; ( ( 3V / 20(Gain) )/ 0,050Ohm ) = 3A max; "3A / (2^12)" = 0,00073242188A Resolution |
| 25 | 22 | Maximilian Seesslen | *** 0,15V * 3A = 0,45W -> CS1206-0R05-1%-HP |
| 26 | 23 | Maximilian Seesslen | ** INA240A1 |
| 27 | 20 | Maximilian Seesslen | ** LM3822MM-1.0 ; PWM-Signal |
| 28 | 3 | Maximilian Seesslen | ** Liegt altes Design noch wo rum? |
| 29 | 26 | Maximilian Seesslen | ** Was fuer OP-Amps liegen denn noch bei mir rum? |
| 30 | 22 | Maximilian Seesslen | |
| 31 | 14 | Maximilian Seesslen | * USB A Buchsen; 1 Stueck on Board (Temprec), Terminal fuer weitere 4 via Kabel |
| 32 | 4 | Maximilian Seesslen | * Timeout |
| 33 | 5 | Maximilian Seesslen | ** Buzzer fuer intervention, startup, shutdown. Hab ja noch genug rumflitzen. |

| 37 | 28 | Maximilian Seesslen | * Button: "Link":https://cdn-reichelt.de/documents/datenblatt/C200/GQ16F-10EJ_-24-S.pdf (liegt hier rum) |
| 38 | 15 | Maximilian Seesslen | ** Schliesser; LED ca. 2V, AC |
| 39 | 33 | Maximilian Seesslen | ** PWM-Signal? Ach nee... |
| 40 | 15 | Maximilian Seesslen | * SSR: AQH3213 |
| 41 | ** Zero cross; VF=1,21V (IF=20mA); 1,2A |
||
| 42 | * MCU |
||
| 43 | 19 | Maximilian Seesslen | ** STM32F042G4U6 (16KB, UFQFPN28) if available |
| 44 | 32 | Maximilian Seesslen | ** STM32F042F6P6 (32KB 20TSSOP); CAN+I2C; The CANSwitch does this with 16K? |
| 45 | 15 | Maximilian Seesslen | * Traffo: "tmps05-105":https://www.tme.eu/Document/d1c9cd5c900987a008a2a0454f3785a2/tmps05-datasheet.pdf |
| 46 | 16 | Maximilian Seesslen | * Terminal |
| 47 | 18 | Maximilian Seesslen | ** USB-Con: #283 |
| 48 | 25 | Maximilian Seesslen | * Current-Measuring |
| 49 | 27 | Maximilian Seesslen | ** 2 * INA138NA/250; USB + VBUS; INA138NA not available |
| 50 | 30 | Maximilian Seesslen | ** LM25056APSQE; only whole 5V current; -solderbridges to set with or without local MCU/SSR- Always with local MCU |
| 51 | ** Start with 30mOhm / 30mV max |

| 55 | 35 | Maximilian Seesslen | * Can an photodiod already replace the button? Do i need an further switching circuit? |
