Icosaèdre Lampe. In this Instructable I will explain the process of building a Geodesic Lamp(s) using Google Sketch Up and an Epilog 120 Watt laser cutter.

But... how do you use them? Where do you get them? 1-watt and 3-watt Power LED's are now widely available in the $3 to $5 range, so i've been working on a bunch of projects lately that use them. in the process it was bugging me that the only options anyone talks about for driving the LED's are: (1) a resistor, or (2) a really expensive electronic gizmo. now that the LED's cost $3, it feels wrong to be paying $20 for the device to drive them!

PICAXE projets n ° 1: Faire Modules circuit imprimé rapides. Pic2 shows a few of the Picaxe modules that I have built and tested that use the Picaxe microcontroller.
They are designed to be modular so that they can be plugged into different robots that are being worked on. Making Ooglo: Luminescent Silicone Paint. Phosphorescent materials have been around for a long time but the newer ones are brighter and longer lasting than the older phosphorescent chemicals.
The sellers of the newer phosphorescent powders are cagey and do not want to reveal what exactly is in their glow powders. It does appear that the best ones available today are Strontium Aluminate that is activated by Europium, In any case, they all work by absorbing visible or Ultraviolet light which charges the photophosphorescent molecules by absorbing the photons and moving the electrons to a higher orbit. As they slowly move back to their original orbits, visible light is given off. The best available phosphorescent powders once charged, will give off light all night long and will still be visibly glowing in the dark twelve hours later. Some of the colors are quite bright and can be used to make a short lived flashlight that is bright enough to read by. PEINTURE EN POUDRE POUR TETE PLOMBEE DO-IT. Faire caoutchouc conducteur: stylet iPod Transparent / iPhone. I call it Oogoo II.
It is a DIY conductive silicone rubber that can be used to create a transparent stylus for iPod, iPhone, iPad, and other capacitive screen smart phones. Because the contact part of the stylus is transparent, you can see your lines and draw more precisely than with a regular stylus. This instructable shows how to make conductive rubber and use it to create three types of stylus: 1 Hack any pen or pencil and turn it into a standard type stylus for pressing keys or drawing sketches while still allowing it to write on paper. Muscles à Air: Faire un contrôleur de robot de muscle artificiel. Although it looks a little bit Rube Goldberg, The 11 channel air muscle controller is fairly simple in concept.
A Picaxe microcontroller (master Neuron) is controlled by an infrared remote control. The master neuron then sends signals to two activator neurons which control 14 solenoid air valves. The master neuron also controls a motor controller which controls the speed of a motor driven pressure/vacuum pump. Member: mikey77 INSTRUCTABLES. [341 - Col du Tourmalet - 2115 m] Retour à la liste 65 Retour à l'accueil Col du Tourmalet. 30 Juillet 2010.
C'est le col le plus prestigieux des Pyrénées. L'un des plus difficiles aussi. Il est en revanche difficile de dire qui, du Col du Tourmalet ou du Col du Galibier, détient le titre du col le plus prestigieux de France et du cyclisme, tellement ces deux cols sont ancrés dans la légende. Dans les deux cas, on est au panthéon du cyclisme, tout simplement. En 1911, Henri Desgrange déclarait que le Tourmalet n'était que de la "pâle et vulgaire bibine" à côté du Galibier. [ Didier Cadelano - Traversée des Pyrénées 2011 ] Richard Miethe. German Engineer Richard Miethe Affirms to France-Soir: "If flying saucers exist, it is the V7 which I built in 1944, the engines of which the Russians seized at Breslau " TEL-AVIV, June (special to "France-Soir") A group of German experts on "V-weapons", who were working for the Egyptian government in the manufacture of radio-controlled missiles, were very recently expelled by the authorities of Cairo.
These specialists of the Physikalische Arbeitsgemeinschaft (PAG), headed by Dr. Kurt Füllner and Mr. Herman Plitzken, had refused to deliver, after the completion of their work, their secret plans to Egypt. After several unfruitful attempts, the authorities confiscated all the goods and the personal effects of the German scientists and refused to pay them the arrears of their wages as long as they refused to deliver the documents. Some of these experts, who collaborated to one degree or another in the manufacture of these rockets, fled to Tel-Aviv. For seven years, Dr. Les tutos maison - Site Jimdo de tricot-vero!
