I've been up to a few things since my last post.

• I've put the RevB V1.0 board into the feeder and have tested it indoors. Works as expected.
• I also added the missing resistor to a new version of the board RevB V1.1 that I have ordered from PCBWay. GitHub is also updated with the latest changes. I'll test this as soon as I receive them.
• I've been asking children's zoos in the area if I can put my vending machine on their grounds for a few months - one has responded and is interested. More on that in September.
• Since I may have a location soon, I've been looking into solar power and have bought a couple 10W 5V panels and cabels. I will need to get a powerbank with passthough charging for this to work. I'd really like to not rely on mains power for reliable operation.

Hope to have some more exicting updates next month.

Once the RevB V1.1 boards get here I will populate one and test again. If it is bug-free, I will give the rest away to anyone that wants to build this.
