Dear Users,

This site has been running for a while offering people user accounts to participate with comments to blog and forum entries. The idea was to provide further features in case people become more participative however, during all those years we had just got spam and a bunch of comments from anonymous users.

So, we had decided to stop these services and block current users accounts as for June the 8th. As far as we know there is no user content stored in the site but be free to get in contact with us for any further query.

Best Regards
The Papermint Designs Community

Hiya!,

Finally I decided to order a BeagleBone Black. I'm looking forward to try it and compare to the other boards I already have. Specially the Raspberry Pi because of the similar price tag. Looking at the specs, there are a lot of interesting features provided by this BBB not easily available on, for example, the Raspberry Pi, or an Arduino. Most of them have been there for a while on more expensive boards like BeagleBoard or Pandaboard but... Having access to this features on a so cheap device is exciting and opens wide the options to learn about technology.

These are the features I'm talking about:

Recently I had the need to produce time-lapse videos for very long periods of time. That is not a big deal when you can use a nearby power source, but I would like to have an autonomous time-lapse camera that can run several hours. So I decided to build it with my Raspberry Pi.

Recently (actually almost one month ago :), I had to power several devices (three different units) using one of those battery packs with an USB output (http://papermint-designs.com/community/node/289). The easiest way to do that is to power a USB hub with your battery pack and then use the hub to provide power to all other devices. That will work OK as far as the current needed by your devices fits the output of the USB hub (around 100 mA).

Hiya!
Some weeks ago I had to show a set of images in something you can "wear" and that sounded as a good opportunity to play a bit with my Raspberry Pi. The first solution (out of three :) I come out with was to convert the images into a big PDF file (thanks ImageMagick) and then use xpdf cool "-remote" flag to navigate the pictures. Do not know about -remote?... Type "man xpdf"!

This is a picoFlamingo minor intermediate release (the second release candidate). Source code is available from the project website:

This release includes some clean up but the main addition is preliminary support for Raspberry Pi, and preliminary means some imitations.

Recently I acquired a couple of HDMI 2 VGA converters. I'm interested on interfacing my small boards to VGA devices and, as many of us already know, finding a working one is a trial and error process. So here are my results and I hope may be useful for somebody else.

I've got two different models (powered and unpowered) and tested them with my HDMI enabled boards (BeagleBoard, PandaBoard and Raspberry Pi). These are the links to the devices in case you are interested.

It took more than 5 month to get our Raspberry pi. It finally arrived this morning. Most of the enthusiasm was gone weeks ago, but anyhow we had to check the board. The initial plan is to port picoFlamingo (http://papermint-designs.com/picoflamingo) to work on the Rpi, but I do not think that anything will happen before Xmas break. Some stuff for PandaBoard needs to be finished first.

Anyhow, a couple of mandatory pictures for new devices.

Probably you already know that the Pandaboard provides two extra USB ports through connector J6 (pin 1 to 8). You probably also know about the nice article in the elinux wiki on how to easily use those (http://elinux.org/Panda_How_to_add_2_USBs) extra ports. I found that article after soldering a female header on my Pandaboard expansion ports.
