Electronics and Enclosure BOM and cost

Here's the full list of parts I used to make the latest version of the electronics on the new PCB and the current PVC enclosure for the Vending Machine for Birds. I had almost all the electronics laying around, but here's what you will need if you start from zero. Keep in mind you can make the enclosure out of almost anything. My first one was made from scrapped ikea furniture found on my street and the second from a wine gift box and a side table - both found in the trash. My latest version is made from PVC pipe, much of which was found in the trash near a construction site.

Total retail cost for all the build parts is just under 100 EUR (98,03 based on the list below).

You would also need the following tools and build materials:

screwdriver
drill
3mm and 10mm bits
hole saw or step drill bit for 24, 38 and 50mm holes
hand saw
zip ties
rubber bands
sandpaper
scissors
velcro tape
double-sided tape
electrical tape or gaffer tape
matte black spray paint
PVC glue
soldering iron
solder
flux

I used Mouser, Conrad, Farnell and Reichelt as the price reference for the electrical components, PCBWay for the PCB and Hornbach, Praxis and Gamma for the hardware. Prices are in EUR.

Electronics: total cost 34,86 EUR
