Ambilight Hyperion Server Automation

Christian Sargusingh

I have experience working with tech startups. I am currently working on drone feedback control algorithms, firmware and hardware for a custom IoT LED lighting system, and optical telecommunications. I am looking to improve my hardware design and firmware integration with modern ARM microcontrollers.

ambilight's Issues

LED Resistance

The PWR led is a bit too bright, using the 3v3 rail or using a higher resistor may be better so it isnt bleeding so much power.

Automate Ambilight Settings Import

Ambilight server and hardware configuration is tedious to rework if the host machine needs to be replaced. Add the option to dump an ambilight config json file for the automation to apply to the new Hyperion instance.

Fan PWR

Cooling for the PCB may be required. If so the board will need to support a flyback diode.

RPi Common Ground with Supply

ws281x drivers require a common ground. Should add a connection to the PWM control JST connector from Pi-> apd.

Hyperion Service fails to start on RPi Boot

From journalctl:

Test Points

Add test points to the board.

v1 BOM

Compile bill of materials for ambilight v1.

Static IP Ansible Role

Create a role for assigning a static IP to the pi.

Inrush Limiter for Transients

To prevent under voltage for other components on the mains power rail I should add an inrush limiter on the power hungry LED drive lines

Add Current Consumption Monitoring

For each output peripheral it would be awesome to monitor their active current draw over time. Particularly for the LEDs.

Automated Configuration

Add tasks for automated configuration into Hyperion

Rising Spikes

Add series 100 Ohm resistor to the PWM line to eliminate transition spikes. (increases rise time by 2ns)

Trace Z-Depth

Increase z-depth of all 3A+ traces.
