I am a teacher of middle school and would like to teach kids on how to make a simple project of turning LED lights on. All the items would have to be from scratch. This includes buying the LED lights from scratch, etc. The lesson needs to be created so that it is very easy to understand and list all the items that needs to be created. It also has to explain what each item does and why it is needed.

Need to develop a GPS tracker, Engine Shut Off, and Passenger Weight Checking device for CNG cars. This device will be outfitted onto CNG cars and will transmit the data through GPRS GSM sim to a central server. The central server can send out requests to shut off the engine. If weight checker is not possible, we need a switch for the driver to indicate his ability. Switch up for available, switch down for not available. Each device should cost under $40 USD to produce. The device can be built with micro controller parts found around electronics stores. The server side aspect can be done by us but if you have experience developing software as well, that is a plus. The software for the micro controller will have to be developed by you. Please provide past work examples, your experience, and how you intend to build such a device. Include the code "343" in your response so I know you read the description. Very important that all these parts can be sourced in Bangladesh or...

We have a .brd pcb board design that needs to be changed to generate 3 more versions of it. A single extra component (PCIX connector) will be added to the board and the rest of the changes will involve taking out components. We need an expert (differential routing with length matching) in Cadence Allegro to complete this work. Attached is a picture of the original board (silkscreen and one internal differential layer) The original board has 12 layers and there are differential pairs on two of them in the area that has to be changed. An experienced designer should use "allegro modules" to do the changes in a timely manner. Back annotation is needed for board version 2 and 3 Board version 1 Take out the area between L1 and L3 Board version 2 Take out the area between L2 and L3 Board version 3 The board is cut at line L0 and we keep area from top to line L0. Add a PCIX connector at the lower edge (where line L0 is) The deliverables are 3 .brd files and manufacturing files ...

I am looking to put an accelerometer, stream chip, processor, perhaps a cache/RAM, and battery into a pair of sunglasses. It will take a stream from a mobile device/tablet/other device via Bluetooth or WifiDirect and send it to OLED screens built into Sunglasses. I plan to pay for all parts and labor. Must send Design and then on approval build the design. PLEASE NOTE: This is to build the circuit. Developer need not worry about the screens. This is a separate job. Optics will play a big role in that project. It must stream in 720p or higher at ~25 frames/sec. Must be able to stream any youtube video. Must be programmable with the the accelerometer. Must be reproducible (I want circuit drawings, pictures along the way, etc.) All work will be shipped to me at the completion at my expense. If the worker completes the project succesfully He/She will be invited to a share of the company.

Hitting the golf ball on the 'sweet spot' of the club gives a player the maximum benefit of a proper swing. We need engineer's to help us build a club that will, on impact with the golf ball, identify on a smart phone or on the club it self, where the club struck the ball (position). Some of possible sensors that could be used are vibration sensors, pressure sensors and then triangulate the point of impact and display that on a smart phone (via BT) or on the shaft of the club with some LED indicators. Any freelancer selected, will be required to sign a NDA and provide references for their past projects. Since we are located in NJ, we are looking for freelancers in NJ, NY, PA and close by region only.

Note: this is just a simple start to a longer motor speed control project. The goal is to create small circuit and a programming for an MSP430 (G2553 launchpad type would be even better) that generate a PWM pattern, controlled by 3 buttons. 2 PWM pattern should be designed: one is constant speed, another one is going from high to low speed then back to high on 2 second patterns. A button does change between one to the other. 2 other buttons are here to be able to modify the speed in the patterns. one to increase, one to decrease the speed. The output should be : -A drawing (even by hand) of the the components on a breadboard linked to the launchpad -the program for the MSP430 to be loaded using CCSv6 I have done such a circuit on Arduino but I am looking to go to TI430 for production. that projects allows me a head start and to learn too.

I need the schematics drawn for me so that I can order some PCB. i need the board to include a 5v lithium ion battery charger which i will be connecting leads to and attaching to a mini usb jack. The board will also need a bluetooth transceiver as well as an amplifier in the 6w-10w range. Either with one channel that is 6-10W or two channels that are 3w-5w each. The board will be used to connect to through bluetooth to a phone or computer and then play music through the speaker connected to the included amp, and all run off of the 3.7v-5v lithium ion battery. I AM ONLY LOOKING FOR THE SCHEMATICS NOT BOARD PRODUCTION. I will use these schematics to submit and order PCB's that are as small as possible and include all desired features.

Hi People, I would like to obtain a quote to design and produce a 220-240VAC 50Hz to 115V AC 60Hz Pure Sine Wave Converter to suit a 15 watt electric motor. The device needs to withstand a Start current of 7 x FLC and have a duty cycle of 20 minutes on/10 minutes off. The device needs to plug into an Australian Power outlet via a flex lead and be equipped with a US plug to accept a US product plug. I would need the design, initially as a prototype in a test box. The design must then be able to go into production in a compact Moulded Plastic case. The case can be an "Off the Shelf" box if it looks professional. The design will need to meet all Australian and NZ standards including AU/NZ Approvals (RCM Electrical safety Mark, A-Tick, C-Tick, MEPS

Basically needing an encryption module to use a key to encrypt a set of operating messages/API into encrypted messages, then after passing through it, it is decrypted using a key, and used by a secondary processes or devices to execute instructions or messages/data. This is to protect the data from one device, that docks onto another station for data retrieval etc. So basically, encoding messages or information in such a way that only authorized parties (docking stations and perhaps a reader) can read it.
