iBionics Insect Cyborgs NEW! Our recent paper on roach-bots in IEEE EMBC and the related video PLEASE FOR A BRIEF HISTORY of OUR PUBLICATIONS Controlled by neurons, muscles are the micro-mechanical actuators of the body. To achieve this goal, we presented a novel surgical procedure at Cornell University to insert artificial implants into insects at early stages of metamorphosis (Figure 1). Figure 1: Summary of the EMIT procedure Sample movie PLEASE CLICK HERE or FOR A SAMPLE MOVIE The EMIT procedure has opened an alternative window for neural-engineers to explore the details of insect flight neurodynamics and its control by allowing the implantation of various micro devices through a simple surgery with minimal or no resulting tissue damage.
RF24Network for Wireless Sensor Networking | maniacbug RF24Network is a network layer for Nordic nRF24L01+ radios running on Arduino-compatible hardware. It’s goal is to have an alternative to Xbee radios for communication between Arduino units. It provides a host address space and message routing for up to 6,000 nodes. The layer forms the background of a capable and scalable Wireless Sensor Network system. At the same time, it makes communication between even two nodes very simple. Today, I managed to get 17 nodes running on a single network. Hardware The fastest way to get RF24Network-compatible hardware is to build the Getting Started board, or the ProtoShield board as explained in other posts, attached to commercially-available Arduino. Ultimately, I wanted something smaller, cheaper and more power-efficient, so I built a Low Power Wireless Sensor Node. Simple Transmit/Receive The Hello World examples illustrate how simple it is to communicate between two nodes. There are three simple sections: Static Initialization setup() Receiver loop()
Instructables - Make, How To, and DIY ArduinoBoardLeonardo Overview The Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. Summary Schematic & Reference Design EAGLE files: arduino-leonardo-reference-design.zip Schematic: arduino-leonardo-schematic-rev3b.pdf Power The Arduino Leonardo can be powered via the micro USB connection or with an external power supply. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The power pins are as follows: VIN. Memory AREF.

Technician Class License Course (Valid through June 2018) How to build an arduino energy monitor Including voltage measurement via AC-AC voltage adapter and current measurement via a CT sensor. This guide details how to build a simple electricity energy monitor on that can be used to measure how much electrical energy you use in your home. It measures voltage with an AC to AC power adapter and current with a clip on CT sensor, making the setup quite safe as no high voltage work is needed. The energy monitor can calculate real power, apparent power, power factor, rms voltage, rms current. All the calculations are done in the digital domain on an Arduino. Step One – Gather Components You will need: 1x Arduino Voltage sensing electronics: 1x 9V AC-AC Power Adapter 1x 100kOhm resistor for step down voltage divider. 1x 10kOhm resistor for step down voltage divider. 2x 470kOhm (for voltage divider, any matching value resistor pair down to 10K) 1x 10uF capacitor Current sensing electronics 1x CT sensor SCT-013-000 1x Burden resistor 18 Ohms if supply voltage is 3.3V or 33 Ohms if supply voltage is 5V.
