Graph Touch for Windows 8

I ported Graph Touch to Windows 8. It's a scientific calculator with graph plotter and numeric solver for maxima, minima and zero crossing. The graph can be paned and zoomed by two-fingers. The numeric solver can be used to calculate numeric solutions for equations. Like the Windows Phone version it's free and without ads.

Simple DIY case for small wares

Here a short description for a rugged DIY case that can be made very easy and requires only simple tooling and easy obtainable materials. Same case type was used for "Data transmission by using the phone display".

The case is made from a middle tube (steal clothes rail) and two end caps with end plates. The end plates are made from 0,7 mm PMMA and hold by the end caps. The end caps are made from thin walled PVC tubing (cable conduit). The PVC tube segments are heated above there glass transition temperature with hot air and pushed then over the ends of the middle tube (thick leather gloves are needed). After that some sanding is required for a nice looking finish.
