The Archos 101 has a crappy touch screen, as all the owners of this device already know. Most of the other problems could be fixed using a custom rom like urukdroid. But the touchscreen has been bugging me for the past year now: the touchscreen sometimes just acts weird (wild and random clicks, or almost no reaction), until it is “recalibrated”. No wonder, since it is a cheap USB touch screen “UNITEC USB Touch (Win7)”, probably made for windows 7 netbooks. Since the recalibration is hidden deep in the android settings, but needs regular access, I wrote a simple app as a “shortcut” to it. You can find the app download link at the end of the article.
This was an old project of mine. A few years ago I had a huge load of data comming in (~4 TiB) and the amount of storage I needed suddenly more than dubbled. Until then I was using two 1.5 TB HDDs which I mirrored by hand using rsync, because I’m paranoid of loosing data. It was annoying to always copy all data to each disk to have redundancy – and certainly not a smart solution. Now that data wouldn’t fit onto the two disks anyway, so it was time to think of a new solution. I had enough of wasting my time with copying files from one hard drive to another.
Some years ago I built a projector, using a overhead prjector and a TFT, as most of you readers know them already. But I never did overcome the problem of keystoning. I know that you can tilt one of the lenses, but with most DIY builds this can be a quite frustrating procedure.
So after many years of looking for a solution thats easy to use, especially because I don’t want that ugly projector to keep standing in the middle of my living room and I always move it to one corner after using it. That means that i have to do the keystone calibration each and everytime I want to use it.
The solution: mplayer already has a perspective correction video filter feature included
