| 3 | 10 | Maximilian Seesslen | Vom Bett aus kann ich nicht mal Licht ein- oder ausschalten. |
| 4 | Ein akkustischer Alarm kann auch nicht quittiert werden. |
||
| 5 | Theoretisch reicht ein einzelner button. |

| 16 | |||
| 17 | -Slider would not have adequate resolution.- |
||
| 18 | 1 | Maximilian Seesslen | Usecase is only on/off. Single Button could do the job. |
| 19 | 2 | Maximilian Seesslen | Fancy ring would be nice. |
| 20 | 3 | Maximilian Seesslen | 90°-LEDs zeigen alle nach 'innen'. |

| 23 | 13 | Maximilian Seesslen | 0602 actually is 0603 when lying. diameter of 2mm is needed. No much space to hide. Just glow from bottom. |
| 24 | red + green. |

| 26 | Having it look like an mini-CANDis. |

| 34 | 14 | Maximilian Seesslen | LEDs: |
| 35 | 7 | Maximilian Seesslen | * Orange, low ambient light |
| 36 | * Blue, bright ambient light |
||
| 37 | 12 | Maximilian Seesslen | * Red, alarm |

| 39 | h2. PCB |
||
| 40 | |||
| 41 | 9 | Maximilian Seesslen | 30x30mm; viel zu klein, touch keys koennen nicht mit ground hinterlegt werden. |
| 42 | 60x60mm; mit "Bauch"; 3 keys; etwas gross |
||
| 43 | 40x40mm; mit "Bauch"; On/Off+Mode; Bauch nur 5mm hoch |

| 44 | 1 | Maximilian Seesslen | logo/sensor 10x10 |
| 45 | 9 | Maximilian Seesslen | |
| 46 | 18 | Maximilian Seesslen | 30x60mm; Like a Mini-CANDis |
| 47 | 9 | Maximilian Seesslen | |
| 48 | 1 | Maximilian Seesslen | border 5mm; thick enough for LWL? There are some with 2mm diameter |
| 49 | 18 | Maximilian Seesslen | |
| 50 | 9 | Maximilian Seesslen | |
| 51 | 16 | Maximilian Seesslen | h2. Dimensions |
| 52 | |||
| 53 | 1 + 3 + 1,6 + 2 + 1 = 8,6 thickness |
||
| 54 | 17 | Maximilian Seesslen | CANDis is only 6mm? probably 8mm |

| 56 | h2. MCU |
||
| 57 | |||
| 58 | 4 | Maximilian Seesslen | * STM32L552CCT6 way too big |
| 59 | 23 | Maximilian Seesslen | * STM32F042 has a touch sensor controller according to datasheet, copilot says "no". I tested it on STM32F042 eval board. WOrks nice. |
| 60 | 4 | Maximilian Seesslen | |
| 61 | h2. To be verified |
||
| 62 | |||
| 63 | * Use Miniminutnik Acryl plates to check if text is readable/illuminated |
||
| 64 | 5 | Maximilian Seesslen | ** Looks very nicely |
| 65 | 4 | Maximilian Seesslen | * Prepare STM32F42x eval board |
| 66 | 22 | Maximilian Seesslen | ** -One touch area directly, another via JST- |
| 67 | 6 | Maximilian Seesslen | ** CANBus |
| 68 | ** Debug |
