Hardware » Takki

h1. Eval

Vom Bett aus kann ich nicht mal Licht ein- oder ausschalten.

Ein akkustischer Alarm kann auch nicht quittiert werden.

Theoretisch reicht ein einzelner button.

Name: takki (IS for "Knopf")

h2. Realization

-Slider would not have adequate resolution.-

Usecase is only on/off. Single Button could do the job.

Fancy ring would be nice.

90°-LEDs zeigen alle nach 'innen'.

"LEDs":https://www.tme.eu/de/katalog/led-dioden-smd-bunt_113363/?params=1113:1500429,1550549_led-diodenausfuhrung:abgewinkelt,horizontal&queryPhrase=LED

0602 actually is 0603 when lying. diameter of 2mm is needed. No much space to hide. Just glow from bottom.

red + green.

Having it look like an mini-CANDis.

LEDs:

* Orange, low ambient light

* Blue, bright ambient light

* Red, alarm

h2. PCB

30x30mm; viel zu klein, touch keys koennen nicht mit ground hinterlegt werden.

60x60mm; mit "Bauch"; 3 keys; etwas gross

40x40mm; mit "Bauch"; On/Off+Mode; Bauch nur 5mm hoch 

logo/sensor 10x10

30x60mm; Like a Mini-CANDis

border 5mm; thick enough for LWL? There are some with 2mm diameter

h2. Dimensions

1 + 3 + 1,6 + 2 + 1 = 8,6 thickness

CANDis is only 6mm? probably 8mm

h2. MCU

* STM32L552CCT6 way too big

* STM32F042 has a touch sensor controller according to datasheet, copilot says "no". I tested it on STM32F042 eval board. WOrks nice.

h2. To be verified

* Use Miniminutnik Acryl plates to check if text is readable/illuminated

** Looks very nicely

* Prepare STM32F42x eval board

** -One touch area directly, another via JST-

** CANBus

** Debug
