There have been a number of changes to the SmartPoi project in the last year. Due to issues I have had while spinning them at gigs I decided to make some much needed changes. This is a major upgrade
- Changed to binary format to save images (in LittleFS file system) – this is so much smaller than the previous text based format, I can now fit 100 offline images onto the small poi and 50 images onto the large poi. The maximum image size is larger. Also, all images can be displayed one after the other. And the timing can be changed for offline images as well.
- Added setup code to the Android app – no longer do I need to run a separate program to set up the test images, the Smart Poi Demo app now creates the correct files and folders*
*unfortunately, Google in their wisdom are removing file system access slowly in newer versions of Android. This means that my code is going to have to be updated once again (angry face emoji)
- Uploading offline images to the poi is simple and available straight from the Android app. An upload image button uploads all of the images at once (one folder at a time only for now)
The Future of Smart Poi
I am planning the launch of a kit version, hopefully this will be possible some time during 2021(*Update: more like 2022). The design will be modular, with the battery, circuit, and LED’s all coming separate. I have a friend who is a qualified designer who will be helping with this part. The idea is to be able to have a ‘snap-on’ LED strip, so that more pixels can be added at a much lower cost than if I was making a whole new set of poi. The same goes for the battery, and even the main circuit (ESP32 anyone?). If I can do it right, it will mean that upgrades will be cheaper and also easier.
The new poi will be known as “Magic Poi”. Future Magic Poi Website here (It’s a fun Visual Poi Comparison site for now..)
