I’ve been using the same old brushes for more than a year now on our “Profimaster Robot Model 2712”. They are a little misdesigned, as the brushes go under the wheels of the robot, which makes them tare.
some of you may know the advantages of electric garage doors. they open from the inside of a car even when it’s raining. the disadvantage is the need for the remote control when you want to open that door. with our garage doors it’s similar. the opener is never there when you need to get in.
so i built myself a keypad opening system.
the original apple ear buds are not known for their comfort. so they are a good piece of old hardware to hack 🙂
i adapted them to have a shackle. this adds a lot of wearing pleasure and stability.
i took a wire to do the framing and some tape to fix the cable to it. then i coated the whole thing with sugru, apparently my new favorite working material.
as i blogged a few days ago, i got a nook (german). as this device only sells in the US it comes with a US power supply. lucky me that the supply supports 100-240 Volts out of the box. so the hack to adapt it to european power outlets was rather simple.
i found myself an old device which didn’t need the jack anymore
