The pointer should be able to move up, down, left, right, and diagonally in all directions. The second thing is to draw on the TV screen. Then an operational amplifier is placed between the receiver data pin and port of PIC MCU to amplify the received signal. Software vs. hardware generated video signals To do that we can get support from this link design must be use pic 16f877a or 16f877A MCU for both side Bluetooth module is BTR 310 or bc417143 module for both side in the keypad side a module configure as a transmitter and in TV side it is configure as a receiver
The device produces 600 different frequencies simultaneously In range 100khz-10mhz. Each bga produces 120 frequencies powered by 3.3V. Furthermore the frequencies are sent in 12V amplifier and through 15 ide cables 40 pins leads to the antenna.rnrnWhat i need is an external device (antenna / amplifier) which will host the 40Pin ide cables (15 headers 2x20) through witch the frequencies are driven to the device which amplifies the signal, so that it has minimum 40M Rangern
I am making a simple arduino prototype and I need help designing a simple circuit to amplify the output (left channel only) from this adafruit breakout () for the VS1053B chip. The Arduino (a teensy 3.0 from ), VS1053 breakout board, and amplifier will all need to be powered by a 3.7V liPoly battery that I'm using now. I have little to know electrical knowledge, and I've been trying a lot of examples from the web without any luck. For reference, I've been using code from this project to get the rest of the circuit/software working: I've been able to get output working using headphones, but not as a line out signal.

...see file for amplifier overview There is a broadband amplifier board (used to read signals from a special kind of photodiode) which needs some additional components. Basically, a comparator which has an adjustable threshold must be added. The analog signal output as it is now has peaks from 0 to -1.5 V roughly, with a width of ~30 ns (negative pulses, kind of Gaussian shape). About 10^6 to 10^7 pulses come per second from the diode. The threshold should be adjustable from roughly -0.1 to -1.5 V using a potentiometer. The original design files are in P-CAD format, which must first be imported into Altium Designer (there is a way to do this, but it might not be completely automatic, I don't know). The comparator circuit must be designed and added to the ori...

This doesnt't mean that it must be based on my design, perhaps you have much better ideas. The price is just an indication.
I am building a bi-directional amplifier which would boost the signal of the transmitter & receiver . I have finished all the circuits but I still have issues related to the driver circuit for the SPDT Switch . The switch has a typical switching speed (Ton and Toff) <15nSec. The circuit driver for the switch that I have drawn has typical Fall/Rise 35nSec and it will turn on and off the switch within 50nSec as the author of the switch claims in their application notes. I need confirmation if this driver will turn on and off the switch within 50nSec and I need to know the delay between 2 control lines VC1 and VC2 . I have also draw another circuit driver that would also provide 35nSec for fall/Rise, but the delay between 2 control lines is about 120nSec. This is an...

I was recently awarded a patent for a modified beverage cooler that has waterproof speakers. I need a 3D model of the design so it can be rotationally molded. It needs to have 2 parts: an exterior shell that measures 20" x 12" x 11.5"; an interior shell that fits into the exterior shell that has 1" of empty space between the shells for insulation. A lid needs to be included in the design as well. Modifications: The front of the cooler must have a hollow panel that extends from the front in order to accommodate 2 speakers that have a mounting dept of 2", as well as a mini amplifier module. There need to be 2 circle holes in the panel with a 4.5" diameter for the speakers to be mounted in. The bottom of the cooler needs a cavity that ...

However, the battery voltage recovers by about 0.2 volts when the load is dropped. This causes the operational amplifier to reset the relay causing the relay to chatter and the LED to blink rapidly. Once the circuit has been interrupted it needs to remain off. Only the circuit diagram and components needed required. I will handle testing and PC board...

...amplifiers in the network will shut off at high input levels, we need the microphone input to be filtered. First it should be amplified such that a user who speaks softly or is too far away from the mic will still be heard. Second the signal should be compressed for optimum speech intelligibility. Third it should be limited not to overload the amplifier. As we are working from Power over Ethernet, we have to squeeze the most out of the power available, so the amplifier operates near its maximum. Hence, *** the limiter should not only cut off peaks but limit the effective power *** in the stream to a maximum. This requires integration of the signal over time. It should also make use of the Windows's functionality to set the mic level if the input level is too high (li...

The MATLAB M-files and GUI will have playing, stitching, editing features to simulate normal and defective ECG signals such as arrhythmia, apnea, and congestive heart failure. The signals can then be converted into actual electrical signal by using the DAC of the built-in-sound card (speaker port) and an external analog amplifier for post-amplification. This human ECG simulator can be used to test electronic circuits for ECG analysis.
