AT Power Supply Schematic
Does anyone have a detailed schematic for an AT Power Supply? My intention is to intercept the DC output from the first stage,before it is converted to high frequency,and insert a separate DC Source,in effect,eliminating the need for AC input. Thanks in advance for all help on this.
Mars Opportunity Defies Expectations
The Mars rover Opportunity landed on the Mars' Meridani Planum on January 25, 2004. Opportunity has traveled 26.2 miles during its nearly 11 years on Mars. To celebrate it's recently completed marathon I figured I'd post some cool images and stats about the rover. Here's a schematic of Opportunity.
Altium And Valydate Announce Strategic Partnership With New Design Analysis And Verification Technology
This new technology will be unveiled January 27-29 at DesignCon 2015 and will aid in streamlining the design process and save designers countless hours from having to visually inspect schematics for errors.
A New Gustometer for Taste Testing in Rodents
In recent years, to circumvent the interpretive limitations associated with intake tests commonly used to assess taste function in rodents, investigators have developed devices called gustometers to deliver small volumes of taste samples and measure immediate responses, thereby increasing confidence that the behavior of the animal is under orosensory control. Most of these gustometers can be used to measure unconditioned licking behavior to stimuli presented for short durations and/or can be used to train the animal to respond to various fluid stimuli differentially so as to obtain a reward and/or avoid punishment. Psychometric sensitivity and discrimination functions can thus be derived. Here, we describe a new gustometer design, successfully used in behavioral experiments, that was guided by our experience with an older version used for over 2 decades. The new computer-controlled gustometer features no dead space in stimulus delivery lines, effective cleaning of the licking substrate, and the ability to measure licking without passing electrical current through the animal. The parts and dimensions are detailed, and the benefits and limitations of certain design features are discussed. Schematics for key circuits are provided as supplemental information. Accordingly, it should be possible to fabricate this device in a fashion customized for one’s needs.
4017 & 555 Police LED Lights Project (noob question)
hello, i am assigned to create a physical project starting from the schematics on the left side. my teacher told me that the schematic is incomplete, so the first step is to corect it and then use pads and then send the gerber files to a company to create it. i started reserching it and every schem
