OPTOGENETIC HARDWARE SETUP

Arthur English's group at Emory has developed a custom device that they have used for stimulating peripheral nerves optically in anesthetized mice using a standard optical fiber. The device is compact, rechargeable battery-operated, and controlled either manually or by computer using an analog input. Essentially, laser LED illumination is coupled to an optical fiber by a collimator and can be attached to a ...

LEARN HARDWARE FIRMWARE AND SOFTWARE DESIGN – BRIEF DESCRIPTION

Edition 5 of LHFSD [ISBN 978 606 92185 32] has been specifically designed to become an educational/pedagogical manual for teachers, instructors, and also for ordinary citizens. Have no fear, dear readers: LHFSD is still addressed to beginners, since EVERYTHING starts from a white page, and then things are developed/explained only gradually [and logically], step by step. Our book continues to deliver exactly ...

8051 Microcontroller Overview & Hardware – Tutorial #1

The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for real-time and Boolean control applications. While some (who should know better) have said that the 8051 is dead, it continues to be a viable choice for both design upgrades and new applications as faster, more adv ...

HARDWARE MAKERS

This is an example of a simple and cheap milliohmmeter that can be made by every maker. The core of the circuit are a current source (LT3092) and a current sense (INA225): a costant current flows through the milliohm resistor under test and the voltage at the current sense output gives the value of the resistor (V=R*I). The milliohmmeter can be used as a stand alone instrument by adding a MCU with at least ...

Hardware Protection – OverVoltage and OverCurrent

Power processing is one of the most important aspects on electronic design. The power is unique for a typical system because it gives the system life. Before starting to make the project for a power supply we need to analyze some aspects: Which kind of radio/electromagnetic interference is the device going to face ? What about maintenance requirements? And finally which environment conditions (temperature, ...
