    Great work!

    Agreed. Not even a circuit diagram. Completely pointless.

    agreed there are no instructions i wish evmadrid did the instruction part not trying to hark on this but this site is for me a place for thought invoking instructions that give viable information evmadrid for you next instrucable can you make a actual instrucable i want to be nice since i really do like the work you do here but on all of your instrucables that i have been to it looks like a product page for a web store

    i know i was harking and going on a rant but sooner or later someone is going to look at these and say there are no real instructions here and they may start flaging

    what would be nice of you too add is
