“So I’ve done persistence of vision displays before; there’s really nothing new there. The challenge this time was to make it small enough to fit on a 72mm longboard wheel, and to make it cheap enough so that I could mass produce it and sell it to folks in the area.”

“I am strong proponent of customized embedded systems; a single piece of hardware aimed at solving a single problem. If we have a particular task that is time intensive, repetitive, difficult to configure and somewhat ‘shady’, it is probably best to execute it in hardware. Lets consider a tool for recovering passwords from PDF-files.”

“This page outlines the complete design for Field Programmable Gate Array (FPGA) controlled robot that exhibits light following, sound sensing, and object detecting abilities. The robot uses an Actel 1020B FPGA to control all of its logic behaviour while external analog circuitry provides the sensory inputs to the FPGA. The purpose of this design is to demonstrate how an FPGA can be effectively used to control a robot.”

“The idea of this project was to design and construct a robot that consists of a body and two wheels that would be able to balance on its own. This behavior is similar how a segway (a new mode of transportation) works. Our goal was to have a working finished product – a robot that, without human interaction, could balance on two wheels.”

“In the days of yore amateurs used to hack a calculator to simulate a keypress to help them count the coil windings. Calculators are relatively rare and harder to tweak these days. There’s an assortment of other awesome tools around however. For example, a Cyclone II development kit.”

“In this article we describe how to build an autonomous robot with a microcontroller that will always try to walk to the brightest spot.”

“The project is about design and implement a device that can hear a Morse code through a microphone and translate the to text. the text will be displayed on a 2×16 LCD screen, so the device can only translate 32 character [aA-zZ 0-9] at a time .We use an op-amp to amplify the sound signal, couple of capacitor to filter out the some nasty frequencies and an ATMega8 as processing unit.”

“I decided to design and fabricate a Botanicalls clone because I also wanted to measure ambient light, temperature, and humidity in addition to soil moisture levels. It also gave me a solid reference point from which to explore a software (EagleCAD) and process I had no prior experience with.”

“It’s wrist mounted and senses objects from about 1 inch (2 cm) to 10 feet (3.5m). It has generally fast response time (fractions of a second) to quickly navigate complex environments. It’s designed to help a vision impaired person to navigate complex environments.”

“The purpose of this project is to develop a more efficient method for performing real-time object tracking….The project has two main components: the support hardware, and the tracking hardware. The support hardware provides the interface to the real world. The on-screen display is used to display the mouse pointer overtop of the video signal for simple point and click object tracking.”
