Happy Halloween!

As a young kid, my parents saved up a small fortune and took me and my siblings to Disney World. While I knew that it was magical, I also understood that it wasn’t actually magic. It was all some kind of clever engineering, created by incredibly smart people. The thing that stuck with me was was the fact that the birds in the Tiki Room, the country bears in their jamboree, and the presidents in the great hall all had their mouth movements synced with their respective recordings.Fast forward to last week, when I was asked, “Do you think you can come up with a blog post for next Wednesday? Oh, that’s Halloween, so maybe something Halloween-themed.” I had a bag of plastic skulls and a box of googly eyes in my drawer (pro tip: Always have googly eyes on hand. They make every project better). So with the help of a Teensy 3.6 and the Teensy Audio Shield, I threw this together. The LEDs on the circuit board were for testing so that I wasn’t sending out the continuous clacking of the solenoids…

ECD Redesigns Signature Temprobe™ for Improved Durability during High-Value PCB Process Characterization

Thermal profiling leader ECD, designer and developer of M.O.L.E.® brand thermal measurement systems, today announced the release of its redesigned Temprobe non-destructive temperature sensing technology. The temperature measurement tool, used primarily for high-value assemblies where conventional thermocouples are not an option, has been re-engineered for increased robustness and longevity.
“By nature, temperature sensing devices that are not mechanically attached to the PCB are delicate,” explains Mark Waterman, ECD M.O.L.E. Product Manager. “Their construction requires the use of materials that can accurately and repeatably measure temperature of key locations on the PCB without any tape or solder and that’s a challenging balance to strike. The new Temprobe design effectively unites durability and temperature sensitivity for repeatable, long-term use and highly accurate PCB temperature measurement.”
Temprobe’s redesign has dramatically improved its ruggedness, but hasn’t altered its…

Tunnel Diode – Working, Characteristics, Applications

What is a Tunnel Diode?A Tunnel Diode is a heavily doped p-n junction diode. The tunnel diode shows negative resistance. When voltage value increases, current flow decreases. Tunnel diode works based on Tunnel Effect.The following image shows the symbol of a Tunnel Diode.Leo Esaki invented Tunnel diode in August 1957. Therefore, it is also called as Esaki diode. The materials used for this diode are Germanium, Gallium arsenide and other silicon materials. Tunnel diode shows a negative resistance in their operating range. So, it can be used as amplifier, oscillators and in any switching circuits.Width of the Depletion Region in Tunnel DiodeWhen mobile charge carriers both free electrons and holes are missing, the region in a p-n junction has a region called Depletion region. To stop the flow of electrons from the n-type semiconductor and holes from the p-type semiconductor, depletion region acts as a barrier.Depending on the number of impurities added, width of depletion region varies.…

What is a Photodiode? Working, Characteristics, Applications

What is a Photodiode?It is a form of light-weight sensor that converts light energy into electrical voltage or current. Photodiode is a type of semi conducting device with PN junction. Between the p (positive) and n (negative) layers, an intrinsic layer is present. The photo diode accepts light energy as input to generate electric current.It is also called as Photodetector, photo sensor or light detector. Photo diode operates in reverse bias condition i.e. the p – side of the photodiode is connected with negative terminal of battery (or the power supply) and n – side to the positive terminal of battery.Typical photodiode materials are Silicon, Germanium, Indium Gallium Arsenide Phosphide and Indium gallium arsenide.Internally, a photodiode has optical filters, built in lens and a surface area. When surface area of photodiode increases, it results in more response time. Few photo diodes will look like Light Emitting Diode (LED). It has two terminals as shown below. The smaller terminal…
