I need to do a lighting system controlled by PIC Microcontroller. This will consist of an array of 9 smd bright LEDs (Osram Oslon SSL leds) controlled by one Ultrasonic Module HC-SR04. An occupancy sensor will start the program if motion is detected in the room, and an LDR (or whichever sensor is best for measuring ambient light) will measure ambient light levels in order to adjust the LEDs levels. When the hand stays at certain position from the ultrasonic sensor, for more than 3 seconds, it will change the light qualities (turning some leds on and off) depending on how far the hand moves from the sensor. I have some of the program written, which sets the ultrasonic module, converts the input into dimensions (cm) and changes the lights according to the distance. I am using a master-slave program and two pics, a a PIC 16F1827 (master, with the sensors) and a PIC16F819 (slave, with the LEDs). I am asking for completing the program, and for the circuit schematic. Ideally some advi...

Summary: I need a pcb design for a small, light-weight, microprocessor-controlled, and easy to assemble transmitter to attach to small animals. Requirements ? Transmission should be in the band between 150.8 and 151.8 MHz. Each unit should have a different band separated by at least 10kHz (i.e. one transmitter might have a band of 150.890 and another 150.880). ? Weight less than 15 grams (ideally). The entire unit should be less than 1cm by 1cm. ? Range should be approximately 1Km ? Battery life should be a minimum of 3 months ? Pulse rate of approximately 1 pulse/second ? On-off controlled by tiny reed switch (magnetic) The units should be designed so that they can be easily constructed (using a tiny pcb as a base). There should be a set of 2 wire leads that would lead out to a small battery. A second lead should be for a wire whip-style antenna. I realize that there are commercial versions of this product available. I am looking for something that students can build on their own...

I need someone that is experienced in Eagle CAD to make a change to an existing PCB. This change consists of hooking up three new low power MOSFETs, adding 0603 three resistors, and rewiring a couple of nets. I will provide both the eagle schematic and PCB, plus a pdf of the new schematic with the changes highlighted. If we are happy with the results, this will probably lead to future jobs too. I'm a circuit designer but I'm not very good with Eagle. So no circuit design experience needed, just lots of experience laying out printed circuit boards with Eagle CAD. Thanks.

We need three white papers developed, one for each market segment, that shows how to use a Solid State Relay in a typical application. The markets are as follows: 1. Aerospace/Defense 2. Medical Equipment (and diagnostics) 3. Transportation/Agricultural Equipment For each whitepaper, we need a problem to be stated (as in motor/heater control, etc...), a circuit design, simulated or tested, results and discussion of the results and comparison to other similiar designs. We are planning on using this for marketing and sending to engineers in these industries to help give them better ideas on how to use our products or give them a starting point or new ideas for the application of our products and/or technical knowledge.

I need a breadboard circuit with the final schematic and the right values and BOM. We need an AM detector which has 120kHz at 2Vpp and is modulated with 32kHz, 10mV. The demodulation sub-circuit has a diode and an RC which has to match. Due to small Signal to Carrier ratio, we will get a huge ripple which needs to be filtered out. The 32kHz comes with 8 periods per bit and has to create an output level of 100mV.

I have to print a lens holder for a lens using a 3D printer. All the specifications and images of the lens and the sensor circuit on which the lens will be mounted has been attached. You have to prepare a profile drawing of the proposed lens holder. Please find attached technical specifications and images of the lens for which the lens holder has to be designed and the circuit on which the lens has to be mounted. Project is really urgent so only bid you can start right-away and produce the first sample output within 24 hours.

I need circuit designed for a solid state relay, optically isolated from output to input to 7.5kV, for a load voltage between 125-250VAC (60 Hz) under a 40A max load. It specifically needs to have less than 100uA of leakage current when it is in the "position". It must also have a tolerance to transients with a dV/dt > 600 V/us and input DC voltage range from 4-32V. I need it designed, analyzed, and tested under a 15A load along with all testing results.

Your job is to. 1- delivery of analysis of the sensitivity (noise/distortion) of power line data transmission to changes in wire length , gauge , type and temperature. Deliver the appropriate data or formula in excel, with supporting literature referenced. (combining two items below). 2-illustrative formula of the time taken to transmit data between two home plug devices for short (distances within a single building) and overview of the accuracy at which software (if written) could record that time. 3- overview of the feasibility of logging the noise/distortion and other data found to be relevant and feasible in item #1. Note: this may be possible in firmware depending on the capabilities of powerline chips, which already calculate and adjust for noise, but may not do so in ways appropriate to this application, if feasible based on the results in #1. 4- the electronic circuit and/or firmware design to log the power line data transmission sensitivity in terms of noise or distortion...

I have a board that was designed in 6 layers, using a blind via and very small trace paths, and as result has increased the production cost greatly. What I need is for someone to take the current design schematic, and either separate the design into two independent boards that interface with each other and mount within the same enclosure space, or fix the board so that it is not so closely to produce, meaning increase the trace or component issues. Because of time, I am in need of this fix quickly, in a matter of days not weeks, so that the board can be produced. So if you are selected for the project please do not agree to this unless you have the skillset to complete it within the timeframe required. This is not a, from the ground up project, as the PCB has already been designed. So the project requires the following just to recap: 1. Separate the existing PCB, (BRD file will be provided after award), into two boards one with 4 layers and another with 2 for example, that result...

Our company specializes in duplicating 125Khz rfid keys for customers. We currently require the customer to send their keys to our facility which is a hassle and not feasible for everyone as a lot of people need to use their keys every day. We are looking for a USB reader/writer that we can send to our customers, which will allow them to read their rfid key data at home and send it to our facility. We have researched using an existing rfid reader but have found none that meet our specific requirements. The main specific requirement is that the reader can be configurable and used on Mac, Windows, IOS, and Android platforms. While many readers operate on multiple platforms, they all require to be configured using a Windows machine. Since we will not know what format key our customers have, the reader will need to be reconfigured by the software program once the user identifies their format. The device will need to be rugged yet small and lightweight. It will need to be able to survive ...

We are looking for a manufacturing company to design and produce a custom RFID chip for use in cards and key fobs. While we already sell these, our supplier is too unreliable. The chips need to emulate the Mifare (13.56Mhz) series of chips but with one modification. That is that block 0 (the UID block) is modifiable. We are looking for a single chip to be designed that can emulate all of the following formats. Mifare 1k classic (4-byte UID), Mifare 1k classic (7-byte UID), Mifare 4k and Mifare ultralight. Special Note: The UID on ultralight is not stored in block 0. The UID needs to be changeable by a standard write to block 0 using default key. Special note: Ultralight can be different method. Based on the cards formatting, it will only take the UID part of the write. We plan on selling these cards to consumers pre-formatted but we will need a small program written based on the ACR122U platform that will allow us to format the cards ourselves. This project is tentative, we are cu...
