Developers look-out! Do not try work out with the applications yourselves. Let´s try programming and designing applications for modules, led directly by specialists from manufacturers.
According to the concept of “SOS = Supplier of Solutions” we will supply not only components but also added value in terms of practical technical training. From June 2012 we will run regular training series called “Pizza Workshop”.
- What is Pizza Workshop? Pizza workshop is thematically focused training, where you can learn more about the practical properties of the different components and modules and get information directly from manufacturers. Learn the best practical use and try it right during the workshop yourselfs on the particular modules.
- Why Pizza Workshop? The simple reason. We want you to feel comfortable, as a developer And so, these workshops will be held in the sign of comfort and a relaxed informal atmosphere. Casual dress, open discussion, rather than a formal lunch simply pizza and soft drinks …
- What to do to be a part of Pizza workshop? Just sign up via the online form. The exact schedule of workshops with detailed information can be found up to date on our website. Note that the number of participants per workshop is always limited.

Convert square wave clock signals to low distortion sinewaves – [via]
This circuit derives a pure sinewave from a crystal-controlled clock source by using a ring counter to remove the highest-amplitude unwanted harmonics, and filtering the result with an 8th-order lowpass, switched-capacitor elliptic filter

I remember I used to have a magic 8 ball key-chain as a kid. I loved asking it the stupidest questions and seeing it magically divine the answer. Either that or it just repeatedly responded with an anti-climatic ask again later. One day the magic just dried up … literally, the purple fluid in the cavity evaporated! Randomly remembering this device, I decided on the spur of the moment, after learning how to seed and use the rand() function in the standard c library, to make my very own digital magic 8 ball (which would be impervious to drying up, but still vulnerable to releasing its magic smoke).

It is one thing to put together LEDs, a few logic chips and a CPU to make something interesting. But, it is a completely different story to connect cables to your creation and try to run various low- and high-frequency signals through them. I’m saying this not to denigrate, but the laws of physics are relentless and good cabling is an area of expertise all for and by itself.
My first encounter with the practicalities of cabling came some 20 years ago when I tried to run a 8MHz digital CGA video signal through 15..25m cables. As you can imagine, my first try did not succeed. I had learned about transmission lines almost 10 years earlier, but never had used it in practice. So, I had to read up on it and understand the problem.
The theory behind transmission lines is well understood, but can be daunting if not versed in the world of analogue electronics. Just know, there is no way you can wiggle your way out of a transmission line’s path. You will encounter them at some stage in your hacking and then you need to solve your problem.
Luckily, there are a few relatively simple things you can do to save yourself from defeat. The problems that transmission lines introduce can be visualized reasonably easy, and, with a lot of pictures, I will try to show you what happens to signals of various frequency and with different transmission line connections.

Go Free Range build outstanding software for the web.. lazyatom writes – [via]
We’ve built an open-source distributed software system for making it simple to produce really great looking content on little printers like that in the IoT printer kit. Take a look here: http://gofreerange.com/printer. I strongly suspect that it would be trivial to get this working with the IoT kit itself. Anyone fancy giving it a go?

Hello Limor and staff,
Long time Adafruit customer here; I really liked your presentation at the Open Source Hardware Summit where you talked about why people should do open source hardware projects.
I’m reaching out to you for help in publicizing my project, OpenBeam. I feel that there is a genuine demand for an extrusion that is stiffer than MicroRax /but still smaller than an 80/20 extrusion, and I don’t think the 80/20 prices are reasonable for hobbyist use with the cost of their speciality fasteners. I’ve also been very frustrated at the technical flaws in Makerbeam’s fasteners (that to my knowledge, is still uncorrected after 2 years), the lack of project progress, and their availability.
I’ve worked very hard to engineer OpenBeam to have all the features of 80/20 (including the hole for edge tapping), being able to price-match against MicroRAX even though MicroRAX has 1/3 the material as OpenBeam, and still have enough margin to sustain this as a business. So far, everyone at the local hackerspace that’s played with the prototype extrusions likes what they see.
4 days into the 30 day funding campaign, we managed to raised 1/6 of the goal. As we approach “The Trench” in the funding cycle, it is crucial to try to keep the interest level up.
Will you be so kind to mention this project in your blog posts

I have been dreaming about having a 3D Printer at home for many years, but the ones with good quality are not affordable and the low costs just deliver poor quality. Sounds crazy but I decided to build a high resolution 3D Printer by myself at home (people actually said that I was crazy and this was impossible). The funny thing I never saw this type of machines in real life, and still haven’t seen one besides the one I built.
Now that I succeed building the first prototype, the target is to bring this low cost 3D Printer to every home, so we are developing the first affordable one with high resolution. I hope you enjoy our blog, follow us and you can have this printer in your home soon.
