For my upcoming Hacks i needed a y-connector ribbon cable. I wanted something quick, easy and cheap to build, still reliable and preferable without wiring. So i came up with this:

Here a very late shout out to an interesting project: control your Arduino via the browser! Basically its a browser plugin to get access to your machines (virtual) serial port. With that you can use javascript to send and receive any data – how cool is that!?

I had the problem of my Mac not going into sleep when external screen is connected and closing the lid. Luckly I came across this advice which indeed, did the trick:

1. Disable external Monitor
2. Type `sudo nvram boot-args=”iog=0×0″`
3. and restart

Voilà!

Hack your whiteboard – and clean it quick!

2012 July 13

For the record: Here’s my favorite realworld hack I got once told by my lovley coworker Roel:

How to clean a messy whiteboard.

Remember the situation when one used the wrong pen for the whiteboard and can’t clean it? Just take another pen which can be erased and go over the non erasable parts – suddenly everything gets clean away:

Or in the words of TvLesson:
Take another dry erase marker (preferably darker than the marks that you are trying to remove) and draw on top of the messy marks. Then wipe the marks away with a dry erase eraser or soft cloth.

The new layer of dry erase marker will lift and loosen the underlying marks. It’s simple but may not work for tougher messy marks.
