This is an English translation of a book that my German Grandmother gave me as a young child.
(Available from Project Gutenberg here: http://www.gutenberg.org/files/12116/12116-h/12116-h.htm )
It uses shocking imagery to teach children simple lessons. It was first published in 1844.

1) Be good if you want Christmas presents
2) Have good hygiene
3) Don't be cruel to animals
4) Don't play with matches
5) Treat people of all races with kindness
6) Be alert when hunting ??
7) Don't suck your thumb
8) Eat your soup
9) Sit still
10 Pay attention
11) Don't play in the rain

I still find these images frightening.

I'm glad this is an old book and most of the lessons are outdated (had the original book on my shelf too).

I developed a simple Frequency Locked Analog Sine Wave generator for Teensy 3.1 to emulate a signal on a rotating machine I use at work. It outputs a smooth sine wave that's locked to a digital 1/Rev pulse train up to 2000 RPM.
Follow the link for the code.
The photo shows the blue digital input signal, and the green locked analog output sine wave.

Paul Stoffregen is working on porting Marlin to the 32 bit Teensy 3.x.
He's looking for testers with 3D printer hardware.
I just volunteered but I'll need to get some new hardware first.

Good point +bob cousins I'd need a bunch of level shifters.... The breadboard idea for testing sounds better and better

I just learned about this Panasonic I2C Infrared 8x8 array sensor.
It might have useful applications for monitoring printing temperatures, bed heat or controlling cooling.:

Temperature range for the Panasonic sensor is - 20 to 100°C, +/- 3°C accuracy, up to 10hz frame rate.  It might not work for monitoring.
USB eval board ~$75 from DigiKey, sensor alone is ~$40 ea.

Melexis MLX90620 is a
16x4 array, - 20°C to 300°C, +/- 1.5°C accuracy between 0-50C.  Frame rate up to 512 hz.
Eval board ~$370, sensor ~$84 ea. from DigiKey.

Getting either to work right requires attention to thermal design.  Emissivity of the object you're looking at changes the detected temperature, accuracy is reduced as frame-rates go up, etc.etc.etc...

3D Printed DSLR Gimbal #celebratephotography #3Dprinting  
https://blog.adafruit.com/2015/06/27/3d-printed-dslr-gimbal-celebratephotography/

Thanks to Mathias for sharing this instructable on our Facebook!

From OpenSAM‘s instructable:

The OpenSAM by OHM is developed for filmmaking amateurs and professionals. The design allows a broad spectrum of cameras of varying sizes and weights to be stabilized. The use of 3D printing technology for the mechanical construction means that it can easily be reproduced and any design changes are easily implemented. The 3D printed parts are also lightweight (actually lighter than any commercial carbon-based designs).

Someone asked for the code...

The Code can be found Here:  https://drive.google.com/open?id=0B1FtmI2UU0R2MHcxQjdTUWk2Z3M&authuser=0
The Pinouts are in the comments
Compile with Arduino1.06 with Teensyduino 1.20
The UTFT Library should already be included, but it's available here: http://henningkarlsen.com/electronics/library.php?id=51

Thanks for trying out my design on thingiverse, and for making the nice video.
My daughter agrees that it is not as comfortable as the polished brass mouthpiece, but still prefers it for marching band in below freezing conditions.
I guess the brass mouthpiece makes her lips numb when it's that cold outside.
A word of caution. one of her band mates tried to snatch one from her baritone horn, and it snapped off flush.
It was very difficult to get the broken piece out.
I have a new all metal hotend and plan to print one out of polycarbonate which should be much stronger.

Thank, and good Luck
Bob

You also can't forget the fact that you could make a few hundred of these for the price of some metal mouthpieces.

Questions/Help  - 
 
I'd like try out some Polycarbonate filament. I'd need 3mm filament for my Mendel90 with E3D hotend. Does anyone have recommendations for a supplier for US purchase? Also any tips for maximizing print quality with PC would be greatly appreciated.
Thanks!

+Sanjay Mortimer your price for PC at E3D is quite reasonable, even with shipping. I wanted to get some spare tips anyway, so look for an order soon, thanks.

Yesterday I received a 2.2" ILI9341 LCD Display. I also just discovered the magnificent UTFT library by Henning Karlsen.
It was very easy to get it working with the Teensy3.0. I probably had it working withing 45 minutes of unpacking the display.
I am using the latest version of software and libraries. Teensyduino 1.18, Arduino 1.0.5, and UTFT V2.75

The UTFT library was just updated a couple of weeks ago, and has Teensy3.x support built in.
The UTFT Library is located here: http://www.henningkarlsen.com/electronics/library.php?id=51

The wiring and the code running in the video can be found here:  http://forum.pjrc.com/threads/25579-UTFT-Library-with-ILI9341-2-2-Inch-240*320-SPI-TFT-LCD-Display?p=45676&viewfull=1#post45676

On both occasions the packages were delivered by A1 International before 6:00pm on the same day without any problems. I live in SE PA in Delaware County, and the packages originated from Middletown Delaware. I am pleased with the rapid delivery service provided by A1 International.
