Quickstart Guide | code.compartmental Setup and Shutdown To start using Minim you must first instatiate a Minim object, which you can then use to load audio files or acquire inputs and outputs. Here’s a partial program that demonstrates these things: Minim minim; AudioPlayer player; AudioInput input; void setup(){ size(100, 100); minim = new Minim(this); player = minim.loadFile("song.mp3"); input = minim.getLineIn(); } void draw(){ // do what you do} If you are using Minim outside of Processing, then before your program exits you must close any audio I/O classes you get from Minim and then stop your Minim instance. Playing A File One of the main motivaters behind writing Minim was that neither of the available libraries for Processing allowed stereo playback of audio files. import ddf.minim.*; Minim minim; AudioPlayer song; void setup(){ size(100, 100); minim = new Minim(this); // this loads mysong.wav from the data folder song = minim.loadFile("mysong.wav"); song.play(); } void draw(){ background(0); } Retrieving MetaData

The Mechanical Vivarium of Dr. Iguana 5V Boost Switching Regulator Here's a little project I put together for a friend. He wanted to build a project that ran off 5V but didn't want to use a 9V battery. I found an interesting part on Digikey that can take the output of 1 or 2 AA or AAA batteries and boost it to 5V. Infact the part can be programed for any output voltage between 1.8V to 5.0V using two resistors. If you leave off the resistors you get a 3.3V output. One drawback is that at 5V output the part only puts out about 200mA with two AA or AAA batteries. The other drawback is that the part comes in an SOT23 package which is pretty tiny. The board is designed to slip over the terminal of a dual AA or AAA battery holder. Here a parts list of what you'll need. The links below lead to a printable PCB suitable for making the PCB via toner transfer. Enjoy.

Spring DVD Training 12: Blender for 3D Printing - Blender Store By Dolf (Macouno) Veenvliet. Blender already supports 3D printing modeling and file-formats since 2002. With the latest Blender version (2.67) this now is even more accessible and powerful with the new 3D Printing Toolbox and real-time Mesh Analysis features. This Training DVD is for everyone who is into 3D printing, beginners and professionals alike. Whether you own your own 3D printer, or use online services such as ShapeWays, this 3+ hours training DVD will help you joining this exciting new Maker era! Dolf Veenvliet is a Dutch artist who has been exploring 3D printing for sculpture design for many years. This DVD has been produced by Blender Foundation.

PLY90 - Ply Products What is the PLY90? The PLY90 is a patent pending connector that is a faster, better looking alternative to drilling and screwing projects together.Save time and energy by not having to align every board and precisely drill and screw all the pieces togetherYou can focus on the design of your creation using a standard construction methodEasily disassemble creations for storage or moving, recycle old projects into new ones What type of materials does the PLY90 bracket work on? The PLY90 bracket has two included screws that allow it to work with all sheet materials/plywood between .450-.755”. What are the PLY90 brackets made of? The brackets are made from high strength aluminum alloy. The PLY90 has wall mounting features Use either of the two holes on each connector to mount shelves, wall boxes and other creations to a wallUse the holes and a screw to mark placement on the wallUse drywall anchors if necessaryRecommend #8 or #10 screws, 2 inches in length for mounting hardware

Bridge circuit A bridge circuit is a type of electrical circuit in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging points is often adjustable when so used. Bridge circuits now find many applications, both linear and non-linear, including in instrumentation, filtering and power conversion.[1][2] Schematic of a Wheatstone bridge The best-known bridge circuit, the Wheatstone bridge, was invented by Samuel Hunter Christie and popularized by Charles Wheatstone, and is used for measuring resistance. The Wheatstone bridge has also been generalised to measure impedance in AC circuits, and to measure resistance, inductance, capacitance, and dissipation factor separately. In some motor controllers, a H-bridge is used to control the direction the motor turns. See also[edit]

AASaver « Rayshobby Update AASaver 2.0 is now available. Buy it from Rayshobby Shop.For details about AASaver 2.0, assembly and usage instruction, please check this blog post. Order You can order the AASaver from my hobby shop. Overview When your electronic devices report that the batteries are ‘dead’ and need to be replaced, do you ever feel frustrated that there is often still a lot of juice in them? Based on an efficient boost regulator IC, the AASaver is a small and multi-purpose boost converter that can help you harvest the remaining energy in AA batteries. Takes up to two AA or AAA batteries. As in the original AASaver, the 2.0 version works perfectly as a small flashlight. I also enjoy it a lot as a compact breadboard power supply.

f.lux: software to make your life better MakerBeam.eu - a miniature T-slot 20 Arduino Projects Of 2012 | Nudatech While looking for ideas for new some new project I noticed there aren’t many lists of Arduino projects online so I decided to make one and in the last few days I’ve been carefully digging Reddit (r/Arduino) and the Arduino forum until I ended up with a list of 20 Arduino projects. All the projects in this list follow two simple criteria: They’ve been published/released in 2012.They provide quite detailed info (the more the better). The second criteria forced me to discard some amazing projects, but I didn’t want this post to be a simple showcase of cool Arduino projects, I wanted it to be an useful reference for Arduino users. 20. arduino-l3dgecomm This project aims to integrate a 3D world with real sensors and motors, more a proof of concept than a proper project, but still an interesting idea. 19. A custom PCB designed in the shape of a Christmas tree, an Atmel ATTiny45 microcontroller, 5 IO pins, and 20 LEDs make a perfect Christmas ornament. 18. 17. 16. 15. 14. 13. 12. 11. 10. 9. 8. 7.

La diode zener: transistor ballast série La diode zener: transistor ballast série De nombreux montages associent diode zener et transistor. Dans tous les cas, le transistor est utilisé pour son gain en courant qui permet d'obtenir un courant de sortie plus important, tout en ayant une tension stabilisée par diode zener. Régulateur série L'inconvénient majeur du montage "diode zener + résistance" est sa consommation à vide, identique à la consommation en charge. Le transistor (appelé transistor ballast) se trouve entre l'entrée et la sortie. Vs = Vz - Vbe Sans le transistor, le montage pourrait fournir un courant ib maximum. is = ib. Remarque : lorsque le courant de sortie est important, la dissipation du transistor peut devenir conséquente. Exemple : alimentation pour ventilateur 12V/200mA On souhaite réaliser une alimentation pour ventilateur de PC (12V, 200mA) à partir d'une tension non régulée qui fluctue entre 18V et 24V. Donnée : Izmin = 1mA, hfe = 100 Réponse Calcul de R La plus grande valeur de ib possible (ibmax) vaut :

_-= Uzzors2k =-_ Project Site Flyback Transformer Drivers The 555 Driver Basic Flyback transformers are found in monitors, TVs or anything with a CRT, and are sometimes known as Line OutPut Transformers, or just LOPT. This is a pretty standard 555 astable design. Winding your own Primary I recommend winding your own primary for several reasons. Standard Monitor Flyback Transformer with new primary. Pinout For those of you who have never seen a flyback transformer before, it may be a bit tricky to know where the primary, ground and other pins are. Pictures Sparks at 5v. Troubleshooting Of course something can go wrong, so if you’re unlucky check these points. If you hear a high pitched whine but you don’t have any HV, you’re close. 555 Driver MKII About 18 months later I decided to try this again, only this time I knew what I was doing. Make your own PCB! I've designed a PCB for this driver which can be edited with ExpressPCB. Pictures 24v input, 3 cm+ sparks 24v in juicy spark Dual sparks Tired of measly 2 cm sparks? Nice.
