Marc Risked His Life on Black Friday to Find us the Perfect Brush

Thanks, Marc! We're glad you made it back alive (see end for more of Marc's breathtaking adventure).

 Beautiful!
 Look at those luscious bristles!

Marc was caught amidst a wave of savage shoppers in the hardware store commonly referred to as Lowes, on Black Friday evening.  As our protagonist neared complete exhaustion, out of the corner of his eye, he caught a glimpse of the most spectacular sweeping machine he had ever seen.  Oh what a glorious day for all of mankind.

The Quest for the Infrared Receiver

Today, Connor and Kate had a little fun with a DVD player, screw drivers, and a soldering iron. Our happy little Broomba chassis kept us company while we did it.

The first thing to do was take off the black covering. That was simple, we just had to remove a few screws.

Here's what we found underneath the outer covering of a DVD player:

And here's a closeup of where the disk would go:

The white plastic that you can see in picture 3 was intertwined with the black plastic and it was hard to shimmy out of there gently. Since we weren't putting the DVD player back together, we just broke it all apart. After unscrewing multiple screws, we were able to find a few motors and some gears. 

Below a small yellow board is shown. You can see in Picture 2 where this was located in the DVD player. Everything was very heavily soldered onto this board so we weren't able to salvage anything from it, but it was pretty fun Googling the serial numbers of the parts to find out what served what purpose on this board.

We found the IR receiver that we need! It was right next to the LED display.

 And for an added bonus, we managed to find and salvage a potentiometer!
