PIC32-PINGUINO-MICRO ARDUINO MAPLE LIKE BOARD WITH USB OTG Open Source Hardware Low cost 32 bit PINGUINO MAPLE ARDUINO like development board ARDUINO like board with PIC32MX440F256H with USB OTG PIC32MX440F256H 80 Mhz microcontroller 256KB Flash 32KB RAM MicroSD card for data logging UEXT connector which allows many existing modules like RF, ZIGBEE, GSM, GPS to be connected Two LEDs One BUTTON RESET button A Mini USB connector is used, which is common and used in most cell phones, so you do not have to buy other cables All PIC ports available on 0.1" connectors miniICSP connector 0.05"step. If you do not want to use Pinguino IDE and you want to program this board with a PIC-ICD2-POCKET or PIC-KIT3, you should use also a PIC-ICSP converter board, the same applies for Microchip programmers. Do not use the "programmer-to-go" button when there is no image on the OLIMEX PIC-KIT3 or MICROCHIP PIC-KIT3 because that might put your microcontroller in an irrecoverable state. Related Products
Cockroft Walton Voltage Multipliers The classic multistage diode/capacitor voltage multipler, popularized by Cockroft and Walton, is probably the most popular means of generating high voltages at low currents at low cost. It is used in virtually every television set made to generate the 20-30 kV second anode accelerating voltage from a transformer putting out 10-15 kV pulses. It has the advantage of requiring relatively low cost components and being easy to insulate. It also inherently produces a series of stepped voltages which is useful in some forms of particle accelerators, and for biasing photomultipler tube dynodes. The CW multiplier has the disadvantage of having very poor voltage regulation, that is, the voltage drops rapidly as a function the output current. It is quite popular for relatively low powered particle accelerators for injecting into another accelerator, particularly for heavy ions. Regulation and ripple calculations The voltage drop under load can be calculated as: Noptimum = SQRT( Vmax * f * C/Iload)
Build Your Own Blocks (BYOB) (formerly BYOB) is a visual, drag-and-drop programming language. It is an extended reimplementation of Scratch (a project of the Lifelong Kindergarten Group at the MIT Media Lab) that allows you to Build Your Own Blocks. It also features first class lists, first class procedures, and continuations. These added capabilities make it suitable for a serious introduction to computer science for high school or college students. SNAP! runs in your browser. SNAP!

LinkIt ONE, la plateforme IoT de Mediatek | Domotique Info Alors, le LinkIt ONE, qu’est ce que c’est ? C’est une carte électronique destinée à diverses utilisations comme le DIY, le maquettage ou les objets connectés. Mediatek, le fabricant de la carte, parle même de « wearable IoT » (internet des objets à porter sur soi). Le produit et ses accessoires sont distribués par Seeedstudio. ( Mediatek surfe sur la vague « Arduino » en proposant une carte qui est compatible avec le format des cartes Arduino UNO, tant au niveau des dimensions qu’au niveau des connecteurs et signaux. La programmation de la carte se fait également à travers l’IDE Arduino et on peut écrire les programmes comme s’il s’agissait d’un Arduino. « Et alors ? Oui, mais là où le LinkIt ONE suscite un réel intérêt c’est qu’il intègre des fonctions qu’on ne retrouve pas ailleurs : Pour achever de vous convaincre, le prix d’un kit LinkIt ONE n’est que $79 , le kit comprenant la carte, les antennes et une batterie Li-Po 1000mAh! .
TIG_Welder_Project This page details the design, construction and fun involved with building my version of a modern TIG welder with 180 Amp capacity and all the features of present day state of the art TIG machines at a fraction of the cost. The project started out as an excercise in frustration. As I'm sure you are aware if you are reading this there is little real in depth information available on the web detailing the design of welders. Lots of block diagram and generalisation......but no real substance, probably because the welding companies don't want anyone to see how simple it really is to produce a TIG unit with real world capability. After over a year of searching out what was required I finally ended up going to component manufacturers application sheets and found more there than was generally available from welder companies. Added four new pictures and nine PDF links for the finished Arc Starter Unit. Some of you have asked which IGBT's I used ?
Pinguino, open source hardware electronics prototyping platform based on 8- and 32-bit PIC from Microchip. V-USB - A Firmware-Only USB Driver for Atmel AVR Microcontrollers V-USB is a software-only implementation of a low-speed USB device for Atmel’s AVR® microcontrollers, making it possible to build USB hardware with almost any AVR® microcontroller, not requiring any additional chip. V-USB can be licensed freely under the GNU General Public License or alternatively under a commercial license. A comprehensive set of example projects demonstrates the wide range of possible applications. Features For a comparison to other USB solutions for microcontrollers please click here. Hardware This diagram shows a typical circuit for a bus powered device (click the image to enlarge). D1 and D2 are a low cost replacement for a low drop 3.3 V regulator chip, such as the LE33. For a prototyping board, please see metaboard. Documentation Resources Download the V-USB package containing a short description and several simple code examples.
