MEMS Microphone Basics MEMS microphones are constructed with a MEMS (Micro-Electro-Mechanical System) component placed on a printed circuit board (PCB) and protected with a mechanical cover. A small hole is fabricated in the case to allow sound into the microphone and is either designated as top-ported if the hole is in the top cover or […]

The cooker hood is a wonderful invention for removing excess fumes and steam from the kitchen. But like all electrically-powered devices, it only works when it is turned on. This was the problem facing [Peter], whose family are enthusiastic cooks who frequently forget to hit that switch. His solution? An automatic cooker hood switch that comes
NEVER FORGET TO TURN ON THE COOKER HOOD AGAIN Continue Reading
Original glowing ornament for your Xmas tree. It’s made from brass rods wired by a freeform method and contains 18 glowing LEDs. Step 1: Tools soldering iron solder soldering paste 0.8mm brass rod 18x SMD LED coin battery on/off switch Step 2: The Rings The main challenge here is to create a round shape from
FDK CORPORATION will begin sample shipment of oxide based all-solid-state battery using high electrochemical potential cathode material “lithium cobalt pyrophosphate (Li2CoP2O7)” which was jointly developed with Fujitsu Laboratories Ltd. February 2017. While applications using various batteries such as IoT devices and wearable devices expand and progress, the specifications required for batteries are becoming increasingly diverse,
FDK introduces high voltage/ultra small size 3V all-solid-state SMD battery Continue Reading
IoT and mobile communications are targeted by the R&S NGL200 power supplies from Rohde & Schwarz. The architecture allows them to function both as a source and a sink, while short recovery times of 30 microseconds enable them to handle fast load changes that occur, for example, when a device switches from sleep mode to
The MCP6V51 operational amplifier provides input offset voltage correction for very low offset and offset drift. This device provides a gain bandwidth product of 2 MHz, is unity gain stable, has no 1/f noise, and provides superior CMRR and PSRR performance. These products operate with a single supply voltage from 4.5V to 45V, with a
Hi guys, my name is Pedro Castelani and I’m bringing you my first instructable: building a two way radio with arduino for, well, whatever you need it for. In this project, we will make two seperate circuits which will act as both reciever and transmitter. The most important components are two arduino boards (all of
In what can only be described as a work of art, [suedbunker] has created a clock under a glass dome. Sporting Nixie tubes, a DS3223, BCD encoders, and MPSA43 transistors driven by an MCP23008 I/O expander it is truly a sight to behold. [suedbunker] has previously created the Circus Clock, a similar clock that celebrated a diversity
At one time or another, most of us have seen a gadget for sale and thought we could build something similar for cheaper. Of course, we’re almost always wrong. Not about being able to build it, mind you. But when you add up the cost of the materials, the tool or two you almost inevitably
This instructable explains how to motorize a time lapse rail using a step motor driven by an Arduino. We will mainly focus on the Motion Controller that drives the step motor assuming you already have a rail you want to motorize. For example when dismantling a machine I found two rails that I could convert into time
