If you have a Up! Mini 3D Printer then we highly recommend obtaining this upgrade. The new UP! Mini Bed Rev 3 reduces warping dramatically (at least compared to our original heat bed).
The installation is an easy 30 second job, 2 screws, one cable and you are right to start printing.
The board not only improves the heat bed performance it includes new indicator LEDs.
Combing this upgrade with the third party firmware gives an amazing amount of control to large print 100 micron jobs on an Up! Mini.
What are you waiting for? Go get it!

Changing the Opto EndStop for Prusa/GRBL to Allow 5V signals
Having built the version 7 Opto Endstop that is the RAMPS standard for Prusa and other RepRaps I recommend a slight change to the circuit.
The official circuit is:
You could go with a 100 ohm resistor instead of 180 ohm.
Sub note, the only difference between the Vishay TCST 1103 and the Vishay TCST 2103 is that the latter has an extra plastic flange to make mounting easier. The actual electronics are the same:

BackgroundThe Raspbery Pi 1 B board is fully capable of adding sound to your next project.
I have several Raspberry Pi 1 boards lying around not doing much since they were replaced by Raspberry Pi 2 boards.
I have decided to use them as general purpose sound generation boards in my projects.
I initially thought of playing back MP3 files over a speaker in response to serial commands.
I have now added the concept of on the fly (not prerecorded) TTS (Text to Speech).
Combining with Vision Processing (OpenCV)
