Trinket Contest Update #2

We Got Featured!



Whoa nelly, the Trinket entries are really starting to rolling in fast now! The last update featured only five, but below you’ll find an even dozen, and there are more coming in as we write!

The contest asks you slap the Hackaday logo onto something for a chance at winning one of 20 Trinket dev boards donated by Adafruit for this contest.

Arduino-Controlled Single-Leaf Shutter


Single-Leaf Shutter

[Kevin] has made an interesting camera shutter mechanism using an Arduino and a solenoid. To keep it extremely simple, he is only controlling a single leaf. In the linked video, you can see him take it through its paces from 1/125 seconds up to infinite. This is, of course, a proof of concept, and [Kevin] mentions using smaller components to make everything fit easily inside a Holga-like body. As he points out in the video’s comments, digitally controlling the flash would be a simple matter as well.

A basic camera is incredibly simple to make, and [Kevin’s] design certainly isn’t complicated. That said, if you look at the big picture, [Kevin] is demonstrating how feasible it could be to build an entirely custom camera with a standard microcontroller as the brain. We can’t help but think of all of the possibilities when you are able to control the entire photo…

Look Mom I can shrink Arduino even more! And it cost only EUR 4.00!

And they did it agin… olimex for the win everybody! Amazing work yet again.



On October 11 I blogged for our OLIMEXINO-NANO which is already in production and will be ready for sale on November 1st 🙂

With dimensions only 30×30 mm NANO is really cool, but we wanted to see if we can go smaller 😉

As you know on November 2 and 3rd there is OpenFest and we are partnering with the organizers and will make hardware hackathon where everyone who want to learn soldering to may build his own Arduino which to take with him. For this purpose we had to make some small but easy to solder board mostly with PTH components which are easy to solder for beginners.

This is how we made OLIMEXINO-85 you see above on the picture it’s only 30×20 mm and it’s made to make easy breadboarding:


For OpenFest we are preparing 100 kits of OLIMEXINO-85 which will contain all components, so everyone who want…

How To Best Utilize And Enjoy Your Iphone

Serial USB for Any AVR Microcontroller


If you’re using an AVR microcontroller and you’d like to add USB to a project, there are a lot of options out there for you. Both LUFA and V-USB add some USB functionality to just about every AVR micro, but if you’d like a native serial port, your only options are to look towards the USB-compatible Atmel micros.

[Ray] looked at the options for adding a USB serial port and didn’t like what he saw; seemingly, this was an impossible task without a second, more capable microcontroller. Then he had an idea: if the goal is only to transfer data back and forth between a computer and a microcontroller, why not write an HID-class USB serial port?

[Ray] based his project on The V-USB library and created a new HID descriptor to transfer data between a micro and a computer. While it won’t work with a proper terminal such…

Inexpensive Robot Tracking System is Swarm Ready



[Ladvien] has figured an inexpensive way to control a robot from a remote PC with a static webcam. Inspired by swarming robot videos such as those from the UPENN Grasp lab, [Ladvien] wanted to build his own static camera based system. He’s also managed to create one of the more eclectic Instructables we’ve seen. You don’t often find pseudo code for robot suicide mixed in with the project instructions.

Fixed cameras are used in many motion capture systems, such as the Vicon system used by numerous film, game, and animation studios. Vicon and similar systems cost tens of thousands of dollars. This was a bit outside [Ladvien’s] budget. He set about building his own system from scratch. The first step was the hardest – obtaining permission from his wife to screw a webcam into the ceiling. With that problem overcome, [Ladvien] brought openCV and python to bear. He created Overlord, his…

Verified Prints with the Atmel-powered MakerBot

Atmel | Bits & Pieces

The MakerBot crew recently launched its Verified Prints program for the Atmel-poweredReplicator 2 Desktop 3D Printer. According to MakerBot’s Kate Hannum, the team spent a significant amount of time testing and pre-slicing Thingverse files to curate high-quality print designs for Makers.

“Load these prepped files directly onto an SD card and print beautifully in PLA on your MakerBot Replicator 2 Desktop 3D Printer. We looked for designs without too many parts, too much hassle to assemble, any glitches or unexpected errors, and that don’t take a lot of monitoring to ensure perfection when printing,” Hannum explained in a recent blog post.

“From now on, whenever you see the black MakerBot Verified Files button on a Thing page, you can click into the MakerBot Verified tab to download pre-sliced .x3g files. You’ll also recognize the files as you’re exploring Thingiverse by the red check mark symbol. You can easily…

Printing Guns?! How 3D Printing Weapons is in the Near Future

Amber McGuckin

There is an emerging player in the gun debate, 3D printers. I was reading news clips on the CTV app, when I came across an article revealing that Ottawa is worried about the prospect of 3D printed guns. Now, maybe you’re like me and confused about how a printer can manufacture a real gun.

CTV News Channel: Lab produces 3D printed gunsHere is how 3D printing works:

-you create a document online (like a blue print/ printing instructions)

-send the file to the 3D printer

-the printer then stacks layers of plastic to create a gun

Check out the CTV article here:

Now it is just the one part of the gun, the part that apparently makes it a gun, that you can print. Here is a documentary on the topic featuring a pioneer in gun printing in the United States. He believes that everyone should have access to a gun, and has devoted his career to making that happen.
