    Audio IC Development Tools Adafruit Silicon MEMS Microphone.

    -Titulo Original : Audio IC Development Tools Adafruit Silicon MEMS Microphone Breakout - SPW2430 (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they don't need a bias resistor or amplifier, its all in one! // The SPW2430 is a small, low cost MEMS mic with a range of 100Hz - 10KHz, good for just about all general audio recording/detection. // This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. // The output pin is not designed to drive speakers or anything but the smallest in-ear headphones - you'll need an audio amplifier if you want to connect the amp directly to speakers // Listen to this good news - we now have a breakout board for a super tiny MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they don't need a bias resistor or amplifier, its all in one! The SPW2430 is a small, low cost MEMS mic with a range of 100Hz - 10KHz, good for just about all general audio recording/detection. This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. To keep the breakout small and simple, we only added a 3V voltage regulator (the microphone requires 3.3V DC) and filter capacitors. No additional opamp is included, the output peak-to-peak voltage has a 0.67V DC bias and about 100mVpp (peak-to-peak) when talking near the microphone, which is good for attaching to something that expects 'line level' input without clipping. The peak-to-peak can be as high as 1Vpp if there's a very loud sound. If you are If you need a microphone with adjustable gain or auto-gain control, check out our mic+amplifier options. If you need a higher peak-to-peak, a rail-to-rail op-amp and some resistors can get you boosted up! Using it is simple: connect GND to ground, Vin to 3.3-5VDC. For the best performance, use the quietest supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the DC pin. The output will have a DC bias of 0.67V so when its perfectly quiet that's what you'll read, there's a little drift. If the audio equipment you're using requires AC coupled audio, you can grab the signal out of the AC pin, which has a 10uF capacitor in series. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones - you'll need an audio amplifier if you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the DC pin directly to the microcontroller...

    Adafruit [3527 PiOLED - 128x32 Monochrome OLED Add-on for...

    -Titulo Original : Adafruit [3527 PiOLED - 128x32 Monochrome OLED Add-on for Raspberry Pi-Fabricante : ADAFRUIT-Descripcion Original: If you're looking for the most compact li'l display for a Raspberry Pi (most likely a Pi Zero) project, this might be just the thing you need! The Adafruit 128x32 PiOLED is your little OLED pal, ready to snap onto any and all Raspberry Pi computers, to give you a little display. The PiOLED comes with a monochrome 128x32 OLED, with sharp white pixels. The OLED uses only the I2C pins so you have plenty of GPIO connections available for buttons, LEDs, sensors, etc. It's also nice and compact so it will fit into any case. These displays are small, only about 1 diagonal, but very readable due to the high contrast of an OLED display. This screen is made of 128x32 individual white OLED pixels and because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness! Using the display is very easy, we have a Python library for the SSD1306 chipset. Our example code allows you to draw images, text, whatever you like, using the Python imaging library. Our tests showed 30 FPS update rates so you can do animations or simple video. Comes completely pre-assembled and tested so you don't need to do anything but plug it in and install our Python code! Works with any Raspberry Pi computer, including the original Pi 1, B+, Pi 2, Pi 3 and Pi Zero...

    VERTER 5V USB Buck-Boost - 500mA from 3V-5V / 1000ma from...

    -Titulo Original : VERTER 5V USB Buck-Boost - 500mA from 3V-5V / 1000ma from 5V-12V-Fabricante : ADAFRUIT-Descripcion Original: Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output // 2A internal switch means you can get out 500mA from as low as 3V, and at least 1000mA from inputs as high 12V // On-board 500mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for 500mA charge rate. Not suggested for iPad (which really needs 1A charge rate). // Full breakout for battery in, control pins and power out // 90%+ operating efficiency in most cases (see datasheet for efficiency graphs), and low quiescent current: 5mA when enabled and power LED is on, 20uA when disabled (power and low batt LED are off) // Convert just about any battery pack to 5V with VERTER - our fresh new Buck-Boost power converter. VERTER can take battery voltages from 3-12VDC and output a nice 5V DC, which makes it a perfect universal power supply for your portable project! Where Verter really shines is when you have a battery or power range that can fluctuate a lot, or you don't know what you'll end up using. It operates smoothly over the 3-12V range, moving from a boost converter (3-5V in) to a buck converter (5-12V in) on the fly. Please note! This chip can do both, but it really works better as a buck converter than a boost. If you need a full 500mA out, it will struggle as it gets down to 3V and the output will sag to about 4.8V (which is still within standard USB power specs). If you only need something to boost a voltage up to 5V and you want it to be really good at it, check out our PowerBoost series, which excel at that. Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. The VERTER has at the heart a TPS63060 boost converter from TI. This buck-boost converter chip can handle a wide range of voltages (3-12V) and has some really nice extras such as power good output, 2A internal switch, synchronous conversion, excellent efficiency, and 2.2MHz high-frequency operation.

    Hilo Conductor Bobina 23 Metros 2 Hilos Trenzados

    -Titulo Original : KOTENIA Stainless Thin Conductive Thread - 2 ply - 23 meter/76 ft-Fabricante : KOTENIA-Descripcion Original: Después de meses de búsqueda, finalmente tenemos lo que consideramos que es el mejor hilo conductor. Es delgado, fuerte, suave y está hecho completamente de acero inoxidable 316L. Una vez que comience a trabajar con este hilo, ¡rápidamente estará de acuerdo en que es óptimo para cualquier trabajo de wearables! Este hilo es de 2 capas, un poco más grueso que el poliéster o el algodón de todos los días, pero es lo suficientemente delgado como para ser cosido a mano en agujas de ojo medio o con una máquina de coser que puede manejar hilo grueso. Debido a que es fuerte y suave, es ideal para cualquier proyecto de textil / e-wearable. También tiene una resistividad bastante baja, 16 ohmios por pie, por lo que puede usarlo para controlar LED y otros componentes electrónicos que usan menos de ~ 50 mA. Debido a que está hecho de fibras de acero inoxidable, no se oxidará como lo hace la plata: sus proyectos no dejarán de funcionar debido a la oxidación después de unos meses y es seguro lavarlos. Sin embargo, este hilo es un poco rígido, se siente un poco como hilo encerado y no es ideal para hacer guantes compatibles con iPhone. Si desea coser hilo conductor en las almohadillas de los guantes, ¡vea nuestro fino hilo conductor...
