    This might be a bit of a ramble, sorry in advance. So I first heard about this kind of poi through a company called "Light Toys". They have a very professional version of what we have been making in this thread. They've made some really great software to use with their "Visual Poi" which just...

    How do boot loaders work?

    Please can someone help me understand how boot loaders work. I understand that they make it possible to program a chip without using the ICSP but that's about it. Many thanks

    Hiya Dan, Great to hear that you got it working. I am currently working on a new version of the poi which will have a way to control the image via a remote system and hope to have it working soon. Arduino programming can be quite daunting especially in the early stages so don't be afraid to...

    Hiya Dan, The error you're getting is also due to a mistake on my part. My poi have a startup animation before the pictures are displayed, just a little something I was messing around with and decided to include. If you go ahead and delete that line the program should compile. Sorry for not...

    Hiya Dan, Firstly I'd like to say the problem you're having isn't your fault, i'ts mine for not looking at my code well enough before adding it to my website. When you get an error like the one you have (missing something.h) <- take note of the .h, it means you don't have a specific library...

    Hiya Po Ting, I am currently in the process of designing a PCB for my more finished version with an integrated charger based on the tp4056. I'm definitely going to rewire the poi to use the SPI pins (I thought it was odd they weren't being used in the first place but I decided to go with the non...

    Make a program to upload images to a Teensy 3.2

    While I realize the effort required to make a commercial product like the visual poi loader, I find myself in the fortunate situation of having enough spare time to dedicate to a project and would like to have a go at making an open sourced version. Would you be able to give me a super quick...

    That'd definitely be something I'd be up for doing. Have you tried any other micro controllers or is the Teensy the only one good enough?

    Hiya mortonkopf. I followed your guide almost exactly, so the same density as yours ( cant remember what it was at the moment ) I am currently travelling but when I get back i'm planning on getting some PCBs made with 2020 SMD LEDs in a 500mm length.
