How-To: USB MIDI Controller with Teensy

Although many MIDI controllers can be purchased off the shelf, there may be times when a DIY approach is more economical or more appropriate in terms of specific design and mapping.This is one of the simplest MIDI controllers that I can think of – it is just a pot (i.e. “knob”) that sends USB MIDI continuous controller data on CC#1, channel 1.Hardware needed: • 1 x Teensy board with pins • 1 x USB A to B mini cable • 1 x 100kΩ B-type potentiometer • 1 x mini breadboard • 3 x breadboard jumpers (can use a jumper kit for instance)Software needed: • Arduino IDE • Teensyduino • A digital audio workstation (DAW) such as Ableton Live The Teensy is a complete USB-based microcontoller development system, in a very small footprint! Key Features: Boards. Serial and Parallel Battery Configurations and Information. Learn how to arrange batteries to increase voltage or gain higher load currents.

Serial and Parallel Battery Configurations and Information

Battery packs achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage to the total terminal voltage. Parallel connection attains higher capacity for increased current handling; each cell adds to the ampere/hour (Ah) count. Some packs may consist of a combination of serial and parallel connections. Laptop batteries commonly have four 3.6V Li-ion cells in series to achieve 14.4V and two in parallel to boost the capacity from 2,400mAh to 4,800mAh. Such a configuration is called 4S2P, meaning four cells in series and two in parallel. Most battery chemistries lend themselves to serial and parallel connection.

A weak cell may not quit immediately but will get exhausted more quickly than the strong ones when in continued use. Single Cell Applications The nominal cell voltage for a nickel-based battery is 1.20V, alkaline 1.50V; silver-oxide 1.60V and lead acid 2.00V. LaunchPad - LaunchPads. BoosterPacks are modular plug-in boards that fit on top of the LaunchPad baseboards.

LaunchPad - LaunchPads

These modules introduce new functionality to the LaunchPad evaluation kits including wireless, capacitive touch, LED lighting and more! BoosterPacks include everything you need to create compelling new applications based on the LaunchPad evaluation kits, including a plugin module, software and documentation.

Build the LED ARRAY ILLUMINATOR - Page 1 of 12. A long range infrared illuminator can be made using many LEDs There are times when the small infrared LED ring built into a security camera will not cover the range or field of view you require, so you will need to find another invisible light source.

Some large infrared illuminators use powerful incandescent light sources that are passed through an infrared pass filter, causing only the infrared component of the light to come through the filter. These types of infrared illuminators create intense heat due to the fact that the white light source must be fully enclosed and burn the unwanted light energy off as radiated heat. Because of this intense heat, incandescent filtered illuminators cannot be used indoors and may not be suitable for many outdoor installations. SDS6062 60MHz 10Mpt 2-Ch Oscilloscope ($329.00) : Saelig Online Store. Curious Inventor Blog - Attach IDC Sockets to ribbon cable. Code, circuits, & construction. MIDI, or Musical Instrument Digital Interface, is a specification for a communications protocol between digital synthesizers and other digital music devices.

code, circuits, & construction

It was developed to be as simple and general as possible, to give synthesizer manufacturers as much flexibility as possible, yet still have their instruments talk to each other without communication problems. MIDI does not define the nature or timbre of a synthesized sound. It merely describes the action of playing the sounds. In a sense, MIDI is a markup language for synthesizers. EEC user programmable module. The TwEECer We offer two models of our product, the TwEECer Base and TwEECer RT, either of which can be used with any EEC we support.

EEC user programmable module

There is no vehicle year or model specific variations to our TwEECer products. Everything you need to tune your setup is included in the purchase price, TwEECer, Switch, Cables, Software (download from our website). Simple! TwEECer Features: TS372. GROVE System. Grove is a modular, ready-to-use tool set.

GROVE System

Much like Lego, it takes a building block approach to assembling electronics. Compared with the traditional, complicated learning method of using a breadboard and various electronic components to assemble a project, Grove simplifies and condenses the learning process significantly. The Grove system consists of a base shield and various modules with standardized connectors. The Base shield allows for easy connection of any microprocessor input or output from the Grove modules, and every Grove module addresses a single function, such as a simple button or a more complex heart rate sensor.

Each one comes with clear documentation and demo code to help you get started quickly. Grove Modules. Guides.
