Correction on STM32 Micro Explorer configuration utility

I recently wrote about MicroExplorer from STMicroelectronics - STM32 visual configuration tool. And I put a hint there: "Hint 2: Manually selecting an input/output role for a pin (such as Open Drain Output) will prevent you from choosing a peripherial in the drop-down menue. The utility will not tell you that there's a conflict - it will just not allow you to choose a peripherial. So my advise is - select all the peripherials first and then start playing with inputs/outputs manually."


Luckily, this is not true. If there's a conflict, Micro Explorer shows you possible candidates for the conflict - on mouse over:

If you hold you mouse over a conflict sign, you'll see what's the problem

Happy configuration!

Cheers :-)

Mechanical endstop salvaged from old CD ROM drive

Wow, been out for almost a month. Now as I'm back home, will start remembering what I did before I left for that long trip.

Meanwhile here's a quicky - if you need a compact two-way endstop (for e.g. a CNC or a 3D printer or else), you can salvage one from an old CD ROM drive. Here's how it looks:

It will serve as TWO endstops (i.e. you'll need a piece per one axis) and will suit most of the projects. Wiring is so simple that I'll not even be going into that. Happy endstopping.

Cheers!

First attempt to create a cheap CNC

Well, here's why I needed those servos: I somehow decided I could build a cheap CNC out of Dremel drilling station. I bought some metal part for about ten bucks and two servos for about twenty bucks a piece.
