hello, I'm looking for someone who has an experience ( most likely an engineer) that can do me a prototype for a compressible ( foldable ) mug. that coffee mug can also can also make the coffee hot by connecting it with a USB. please keep in mind that i need a working prototype because the mug will be taken into a next level which is manufacturing. if you can deliver me the followings, then please send me your proposal. ? a working prototype of the mug ? the that can be compressed ? the mug has somehow a heating feature ? he mug should be printed and shipped because no 3D prinitng companies are available here ? milestones should be given every while ? the work should be done fast because its a part of a graduation project please take into consideration that the budget doesn't include the cost of the prototype 3d printing.

Hello friends how are you? My problem is this: I am using a PIC16F887 microcontroller to program with C CCS pic c compiler. I have two push bottom one for and one for RB5 RB4. When I press RB4 a green LED should flash for 7 seconds, after which it goes and lights a red LED. When I press a push botom to RB5, the red light goes off and a blue LED blinks for 7 seconds, after which the program is reset, ports and flags are cleaned to start a new cycle. It is very important that must be programmed in CCS C

This project is specifically for the optimization of a Serit SP2636 Tuner using the ST Chip sets STV6110A and STV0903. We have the circuits working but do not perform as good as another similar system that we built. The Serit SP2636 is equivalent to the Sharp F7HZ0169 tuner can. The will require an advanced knowledge of DVBS2 circuit design including external hardware and the ability to optimize the software until the performance of this Tuner PCB matches our previous design. Experience in this area is a must.

Need a DVR surveillance system designed and prototype. Preferably be able to record on a Flash drive or SD card. This system needs to be as small as possible. I would be completely fine with a USB port connected to a camera that plugs into a Flash drive. Need the system to be able to hold at least 2 cameras and record even after a vehicle or motorcycle has been parked. To conserve battery the system can go to sleep after a certain period of time of inactivity.

I have an idea that not only will be useful for me but many other people. I want to make a motorcycle lock with alarm, similar to Xena. This lock will have a remote key fob that will disable the electric shock option. The problem with the XENA locks is that, you can cover the speaker with your finger and the alarm can't be heard. After 15 seconds the alarm shuts off. Please respond with quotes and proposals.

i need an engineer to design me a device that is hooked up to the owner's shower. This device will be able to turn on the shower or bath with the press of a button. It should be as easy to press as an iphone. The device will also be able to connect to the owner's bluetooth on whatever wireless device. The device will have some kind of speaker implemented into it that will allow for music to play through. The device will also let owner choose temperature. They can control the temperature by increasing or decreasing by pressing up & down arrows. The hotter the temperature the redder the numbers get. Colder they get bluer.

1) RFID based locking solution (Mandatory) ? Making an RFID based lock. ? Integrating the RFID based lock with the Raspberry Pi/Black Beagle. ? The Raspberry Pi should contain the database of RFID tags, which can be updated via an online server (Azure Web can be used to create the web interface), and we should be able to add the RFID tags directly using the web server. ? We must be able to get the logging data (check in time, checkout time, RFID tag no.) on either a note or excel sheet. ? Remember, only one user should be able to use the locker at any given point of time. Reference to how it may look like:   [obscured]  /watch?v=4lra1Y2RsWM 2) Temperature control ? Will be using a simple exhaust fan connected to a relay. ? Measure the temperature using a temperature sensor. ? The raspberry pi should signal the relay to turn on the fan when temperature inside the locker goes above 77 degrees Fahrenheit. 3) Capturing videos and streaming our Internet. ?

We are looking for a talented FPGA programmer to help us implement a low noise (<10nV/(rootHz)) lock-in amplifier for heterodyne detection of sideband signals. Carrier frequencies range from 0.3 to 1.5MHz. The lock-in amplifier must have the ability to generate signals at specified frequencies and demodulate signals at the sum or difference of two frequencies (FM/heterodyne detection). Your job will be to develop a working prototype that does the following: 1) Takes in signals via a high speed, 16bit ADC 2) Generates a sine wave with programmable amplitude (ranging from 0 to 5V) and frequency, f2 = (1 to 1000Hz) 3) Demodulates the signals at two frequencies f1+f2, f1+2f2. f1 is determined from the ADC input. f2 is the frequency generated in step #2. 4) Outputs the RMS amplitude of the two demodulated signals via a low noise, 16bit DAC. We have an ADC and FPGA eval board already chosen, part #'s AD9268 and HSC-ADC-EVALCZ from Analog. You will need to help us choose the DAC and fi...
