Yesterday, Mark Miller shared his wonderful home made 3D mechanical scanner project in our Community. Looks great!

This is my second homebuilt scanner, and is much faster and easier to use than my first. I wanted this to use in conjunction with my home made CNC machines(see my profile page for more info on them), this one specifically for the mini lathe to scan a profile of a part directly into the machine for part production. This is made from bare minimum scratch. The sensor array the line laser shoots into, is made up of small rectangular individual sensors 1/16 inch wide each arranged in a row so each turn of the leadscrew “snaps” a picture from the sensor array and sends it into memory. Very challenging to get them all perfectly lined up, but they are so very inexpensive(less than 5$) that it made it worthwhile. The resolution is good enough for what I am doing.The line laser is from ebay. A pic controller runs the stepper and logic. Output is 8 bits wide. (read more)

Thanks so much to AlexFW for sending in the tutorial for his awesome, arduino powered sentry mount project.

Hey Adafruit, I’ve been buying your stuff for a while now,
and I absolutely love the Pro Trinket. Using the Pro Trinket 5v, I built a
really cool project that I just posted to Instructables (the link), and I
thought I’d tell you about it because this is an example of a situation
where only the Pro Trinket would be suitable. It would be so cool to see you
guys mention this in the blog.(read more)
