- Would be interesting to build a multi-function RGB color display device.
- Good to have display of time, images and any other chamak (custom messages, RSS Feeds,etc)
- ESP has good support for RGB Led via the Fastled library.
- Bought and interfaced an 8x8 RGB from an online store with an esp8266
- Fabricated a casing with the face and the box from Vedanta Industries on Magadi Road.
- The Fastled capabilites/effects are as below
- Raw images generated by gimp were used to show images as below.
- Random images could be generated as an 8x8 bit field.
- Could support emoticons.
- An RTC DS3231 was added and a smaller 4x4 dot font was added.
- This was too small to be intelligible and needed familiarity with the font.
- An AWS instance was used to serve out raw images and also to cache a few RSS feeds.
- This device would just access the service to either sync time/images or use a random headline from an news site like Times of India, NYT, WSJ, etc.
- It could be extended to add other social media support as well.
- The video below shows the usual effects with time, images and RSS. Sadly this was during the COVID-19 times and all the headlines were virus related.
