New zero! With my SDIO WiFi board and the cam connector I can stream video with the USB port completely free for something else!

The Koch brothers reportedly want to undermine electric cars. And Musk is not happy.

Has anyone used printed t-slot corner brackets? Or know of a beefier printed corner for the extrusion?

I want to convert my MendelMax to a Eustathios-style printer as cheaply as possible. I know I'll need some more GT2 and 6 pulleys but that should be about it. I might try printed pulleys and see if they are as bad as I think they might be.

I plan to use printed sliders (possibly with bearings) running on extrusion for the Z rather than buying more smooth rod.

Designed a new 3D printed Robot. Used Tinkercad which is actually really cool! Its made for the Raspberry Pi A+ / Zero. Used spare ultrasonic module and cheap stepper motors and its all powered by a cheap USB battery. No soldering required.

Questions/Help  - 
 
Has anyone used a tiny motor in a 3D printed thing? I'm talking mini rc quad/helicopter/'coke-can car' style motor.

I think the shaft is too small to print a hole which would grip and the teeth on the pinion that comes with them are probably too small to print a gear too. Has anyone done this?

I'm thinking something like this http://www.aliexpress.com/item/Hot-DC-6V-Micro-Electric-Mini-Reduction-Metal-Gear-Motor-30RPM-For-RC-Car-Robot-Model/32383297014.html or this http://www.aliexpress.com/item/2Pcs-Lot-TT-Motor-Smart-Car-Robot-Gear-Motor-for-Arduino-Free-Shipping/1370468727.html would work but probably be too big for my purposes.

Print a hole slightly smaller than the tiny included pinion gear and press the pinion gear into the printed part. Like adding a threaded insert to a printed part, but the insert is the pinion gear.

+Brandoan DiVinchi have you connected it via GPIO serial or USB? Are there any tty devices in /dev?

Following the discussions and debate with 'Sad face' and the #Thingiverse / eBay +Louise Driggers

I'm trying to work out if this last part of the new post by Michael Weinberg is correct - (the part about the Sad face image being CC licensed) - I am convinced that only the 3D Model file is being submitted under the CC license to Thingiverse and that all images and photography retain full copyright by Loiuse.
You can download is the STL - You have to take the image by right clicking - it's not listed as a part of the 'things files'

Because Just3DPrint are using other people's images and photography, they are breaking copyright. They seem to want to debate CC licenses and ignore copyright, their latest responses on Thingiverse are shocking.

To be fair I just asked Michael on Twitter, and he has now asked Louise for permission, so that's a tiny result. Now if only everyone was nice and asked the designer for permission and respected the license and wishes before they started doing whatever they liked.

We do have fair use for blog posts and news articles - but the main point here is - Don't assume a 3D File with CC license is also for everything else.

Anyone else buy the $15 Orange Pi? Swore I'd never get another product with an allwinner chip but a board that cheap with a 1.6ghz quad core cortex-A7 and a gig of RAM is hard to say no to!

A physical inspection is worth 1000 dmesgs... Had this weird problem of my microserver going into S3 randomly every few hours/days. Turns out it has a feature that if it's getting warm it presses it's own power button. Anyway after a few hours of remotely trying to figure out what's going on I go to plug in a monitor to check the BIOS and see this.

That was clean when I moved the server about 3-6 months ago! I've set myself a Google calendar to go and clean it in 6 months :-D
