DIY Pick and Place V2 Project Complete
The DIY pick and place machine project is now finally running and is able to place the components for our Raspberry Pi expansion boards. This project started in July 2013 when we began to order the various components, bearings, motors, drive systems, frame materials etc and we started to build the machine in September. Various stages of this project have been posted in the DIY Pick and Place category on the blog and this post will be an overview of all the stages during the build and the problems and issues we had to overcome. This blog post is split into the following sections: You can click on any of the photos to view larger versions. Project Overview and aims Early in 2013 we found that the manual pick and place machine we had built to place the surface mount components on our Raspberry Pi expansion boards was too slow to build the number of boards we needed to sell on our online store.

Juste avant l’été, Marine Royer, de l’école de design l’ENSCI-les-Ateliers, m’avait contacté afin que La Paillasse accueille les étudiants designers de son premier workshop “Biotechnologies” lors de leur premier journée, ceci afin de casser le mythe des laboratoires tout immaculés des films/séries B. La biologie pouvait se faire autrement, en toute indépendance et ouverture, dans un squat à vitry sur seine. Pari réussi :) Read more Du 3 au 6 octobre se déroulait à Rome la première grande édition européenne de la Maker Faire. - Cher tous, La Paillasse vous propose une aventure scientifique sans pareil !

Protei 011 "Optimist" Kit – Scoutbots
Protei 011 "Optimist" kit is now available for anyone to buy as a commercial prototype . Protei 011 is the first wind-powered robot with a controllable shape-shifting hull. Most sailing boats have a centre board and a rudder ; Protei's entire hull can be controlled remotely providing amazing manoeuvrability and sailing behaviour. We believe that the controllable hull is the next step in the evolution of sailing science. If you buy from this page, you get the Protei 011 as a kit that you have to assemble yourself as an IKEA or LEGO kit but quit harder, and you will need a well equipped workshop. Protei 011 Limited Edition ready to sail in a corrugated paper box (840$)Protei 011 Limited Edition ready to sail with it's rugged travel box (coming soon)Do it yourself from scratch following our instructions on instructables. You are buying a cutting edge technology in that the science of the shape shifting hull is yet to be understood. Technical specifications once assembled

Greffage | Ma passion du verger
Le greffage est incontournable pour multiplier arbres fruitiers et plantes, qui conserveront toutes les caractéristiques génétiques de la plante mère. Bien que délicate à mettre en œuvre, mais passionnante, cette opération chirurgicale a donc pour mission de reproduire les différents végétaux en unissant deux espèces. Quelle satisfaction et quel plaisir de faire soi-même ses arbres fruitiers au lieu de les acheter, d’avoir réussi des greffes et de les voir pousser. (Cliquer 2 fois sur les images) Greffer est une technique de multiplication qui consiste à mettre en étroite union deux végétaux. Greffage bois de deux ans. J’ai appris à greffer lors d’une formation arboricole, chez mon ami moniteur Armand Lang, qui m’a transmis son immense savoir-faire et son virus pour l’arboriculture. Greffage de quetsche Stanley + quetsche d’Alsace + pruneau d’Agen et mirabelle sur la même branche. Le prix de l’Ouvrage envoyé par la Poste est de 32€, frais d’envoi compris, sous carton/poste.

Building your own CNC milling machine
Already at the age of 12 I was dreaming of making a machine which could make things! A machine which would give me the opportunity to create products for in and around the house. Two years later I stumbled ont the words 'Computer Numerical Control' or more specifically the CNC milling machine. After I found out people were able to build one themselves in their own shed, I knew it! I had to build one, I yearned to have it!! In August 2013 the idea to build a CNC milling machine captivated me again. This Instructable will show you how I built my CNC milling machine.
Heavyduty Workbench / Shop Cart
Good Afternoon y'all, Mrs. Gnome has been requesting that I do something with the garage. I suppose tools and jugs of used motor oil lined up against the wall are not cool enough for her? Oh well happy wife happy life. I have been tinkering on a salvaged wooden teacher’s desk in our utility room, but I need an actual workbench. In addition to being a sturdy base for banging on stuff; I wanted 2 adjustable lights (one with a magnifier), a minimum of 4 x 110v outlets, a small vise, and storage for my larger tool boxes. Like most of my projects I tend to overthink them, and write it in a little notebook. I should warn you I went pretty picture heavy if anything brings a question to mind feel free to ask in the comments. ANSI rated safety glasses and a dust mask; you are only issues 2 eyes it is up to you to protect them.

Whip Grafting
Grafting is one of the oldest methods of plant propagation and is standard practice today for various types of fruit trees. Whip grafting is an easy technique for the beginner, and has yielded good results for me with apples, apricots, plums and cherries. There are several other grafting techniques - bud grafting, cleft grafting, and bark grafting being some of the common ones. Why is grafting important for the home orchardist? This is a useful technique for people with small backyards. Instead of a tree bearing a large quantity of the same variety of fruit at once, you can spread the harvesting season (since different varieties ripen at different times) and harvest multiple varieties of fruits, with different flavors, shapes and sizes. When to do whip grafting? Compatibility We need to observe compatibility between the scion and the host branch.
100% Homemade Lathe
Although I know other people have built lathes themselves, after an enormous amount of looking on Google, I saw most homemade lathes involve casting and milling, as well as using off the shelf components like chucks and tapers. Being only a high school student, I wanted to experiment with a lathe without having to spend hundreds of dollars that I don't have. I ended up using almost all scrap materials from my basement, so there is no need to follow my materials choices. Because your design choices will vary, this article is more of a record of how I built this one, rather than a manual for building yours. I managed to build this lathe in about a week, with not much more than a cordless drill, a drill press, a jigsaw, and assorted hand tools. I hope that I have documented my project here in an understandable way. Warning: This is a powerful device designed to spin stuff quickly.
