Speaker wiring note: All speakers have a resistance, called Ohm. If a speaker has 8ohms, and you wire 6 of them up in series, the resistance will be 48ohms (6 x 8 = 48), which is too much for an amplifier. Wiring them in parallel results in 1.4Ohms (8 / 6 = 1.333) which is too little for the amplifier. So, what I did was divide the 6 speakers into 3 sets of 2, and wire each set of 2 together in series for 16ohm. I then connected these 3 16ohm sets in parallel to result in an overall resistance of 5.4Ohms, which should be within a typical expected range for an amplifier (4 to 8 ohms).


  1. Using hot water to stop the demisting is just ridiculous. You can buy 12volt demisting pads that just stick onto any surface.

  2. is the sponsor harry's or hairies

  3. Ya know… What you did is kind of smart and risky. Makes for a great video. However it waste water and ties up one of your water sources.
    The simple solution to an anti fog magic mirror is to just use rain X anti fog. It's cheap, only takes a couple of minutes to apply and works great.
    Anytime a project is done remember to K.I.S.S. it. Keep it simple stupid.

  4. Love your videos, a suggestion definitely avoid fiberboard for humid places, is the queen of molds! even if the glass is preheated the fiber board suck all possible humidity and creates mold between the wall and the glass. Perhaps a striped pine will works better.

  5. I got a project for you.. because i'm really interested in if this is even possible: making an info screen! I mean, combining a touchscreen-monitor with smartphone features.. an info screen for the busy- private person or the casual businessman…

  6. Anti fog coat would have worked too.

  7. At 2:04 he says he found this old miter saw in his friends 'Gar-idge'. I had to pause and think a moment. OH, Garage! (gr·

    aazh) Love his accent and this channel.

  8. Hmm. Wood glue is good at gluing 2 pieces of wood together, that's why it's called wood glue!

  9. Can you do one for me and at what cost please plus shipping to Britain 🇬🇧 ?

  10. I bet this guy's house is full of usb batteries attached to everything.

  11. love this channel & the ideas he comes up with love it

  12. You can watch YouTube videos while you're having a sh… ave.

  13. Really pricey, can't do that in a third world country with an insane exchange rate and limited products, I thought you were gonna use Raspberry pi or sth cuz thats more affordable. Anyways, good work and I hope you make a vid of a smart mirror ( that steams just fine) using RP 3 or zero or whatevs. THANKS

  14. The other way without water is apply on the surface shave cream clean the mirror with that and the steam dosen't affect

  15. Idea is not better to put mineral oil and live it inside not water

  16. 2:30 why is he drilling his hand

  17. He could be a Discovery Channel narrator

  18. the lcd shines through the black foil of the pcb??
