  1. hope u see this comment how to make a huge one please i need one for the street and i wanna know everything about it like the code and the led matrix ?

  2. I'm a bit late to the party, but lol to the "Hammer Drill" bit.
    been binge watching your videos, very inspiring/great stuff Bob!

    PS see what I did there? Hammer drill BIT…yeah….i'll stop now.

  3. oh and if 35 dollars is too much, the pi zero is 5 dollars, but you need ethernet or the zero w for 10 dollars to use it with wifi.

  4. Should upgrade with jacks on the boxes and just run CAT5 cable between them and plug them in. Then it is much more modular for just a little extra cost.

  5. Hello Mister Make Stuff Bob !
    First, I watched all of your videos since I discovered your channel, and I've started to make my own kitchen cabinet with a drawer for the trash can! 🙂

    Second, I have two suggestions for you : Why not make a "smart mirror" ? With a rasperby or something else, and can you make a sausage cutter ? Like this : https://www.tompress.com/I-Grande-17895-guillotine-a-saucisson-et-saucisse-seche-en-bois.net.jpg

    Big up from France ! And continue your channel, you make this great !

  6. Hi Bob,
    Great project! do you have a wiring plan or schematic for this project that you would be willing to share??
    Thanks,
    Ken
