Name/Nationality/Ethnicity - Marcin Jakubowski, Polish American Location – what is your city and country? - Aptos, California, USA; Kansas City area, Missouri, USA Contact Information – opensourceecology at gmail dot com, Skype - marcin_ose Introductory Video- see this from August, 2010Resume/CV – Marcin Jakubowski Resume - old resume until end of grad school. Since then, I've been a migrant farm worker, self-made industrial designer, and lead developer of the Global Village Construction Set, mostly at Factor e Farm. WHY are you motivated to support/develop this work? Do you endorse open source culture? I think that the only way that humanity can transcend its continuing decay of equitable wealth distribution is by endorsing open source economic development.
Why are you interested in this work? I founded Open Source Ecology. Are you interested in teaching about the GVCS? Yes. No. Design. Utiliser un arduino comme programmeur ISP - KubuntuBlog. Arduino on a prototype board. Arduino is a great prototyping platform and most of you probably know already about it. If not, check out the Arduino pages and the Arduino playground and dive into it. A couple of month ago I ordered my first Arduino board. It was one of the Diecimila revision. As I often try something on my breadboard, I found out, that it can get troublesome to connect the Arduino with the breadboard over and over again. So what to do if these boards are far away across the ocean and it is holiday season everywhere?

Incroyables Expériences [62] Faire un joule thief 2 / Make a joule thief 2 (récente) Build Your Own Lenses. Nikon, Canon, Leica, Pentax, Sigma, Tokina, and a host of other lens makers are all striving to bring you the sharpest lenses with all optical aberrations reduced to the minimum. That’s too bad! Because with lenses, as with life, sometimes it’s the imperfections that make things interesting. The image on the left was shot with the imperfect optics of a homemade lens.
Exploring the soft, dreamy world of DIY camera lenses in surprisingly easy. There are two components necessary for a homemade camera lens suitable for use on a SLR or DSLR: the optics (to focus the light) and the mechanics (to hold the optics in place and hopefully provide a method of adjusting the focus and aperture). The Optics Any lens that focuses light (a double convex, plano convex, or positive meniscus) can theoretically be used as a camera lens.
Notice that I used the word theoretically above. So unless you already know the focal length of your lens, you should measure it. Starting Simple Adjustable Focus Results. Making your own 4 bit computer from transistors. Learn about the 555. The 555 Integrated Circuit (IC) is an easy to use timer that has many applications. It is widely used in electronic circuits and this popularity means it is also very cheap to purchase, typically costing around 30p. A 'dual' version called the 556 is also available which includes two independent 555 ICs in one package. For the 555 to function it relies on both analogue and digital electronic techniques, but if we consider its output only, it can be thought of as a digital device. The output can be in one of two states at any time, the first state is the 'low' state, which is 0v. The second state is the 'high' state, which is the voltage Vs (The voltage of your power supply which can be anything from 4.5 to 15v. 18v absolute maximum).
The most common types of outputs can be categorized by the following (their names give you a clue as to their functions): Monostable mode: in this mode, the 555 functions as a "one-shot".
