This project is going to be the hardware version of an encryption system.Please read my work at   [obscured]   Spend sometime on that before contacting me. If you really want the bid my suggestion in order to help will be for you to know my work first. ****************************************************************************************** The scope doesn't preclude designing two hardware module that can be programmed and reprogrammed with ease. They will be able to encrypt and decrypt signals on a physical level. The idea is very simple... The device will come in as a pair: Each will hold a basis of any chosen language in an eeprom and other functions are as follows: 1. Standard State Template(ST) this will host: a) Basic Latin (96) b) Latin-1 Supplement (128) c) Repeat 0-31 basic latin (32) I will add 64 more bytes in the life cycle of the project as that is desirable for competitive edge. What I who now will work for all Latin root languages. We can equally expand/create an a...

Currently, we are producing a small frequency generator, using THT and a NE555. We would now like to switch to automated SMD manufacturing and offering new features. We need you to layout and design the PCB board, create a BOM and everything else needed for manufacturing. The unit needs to be low cost, and should offer the following features: Choice of 3 Modes: 20kHz frequency continuously, 20kHz Frequency timed (5 mins on/ 5 mins off), 1kHz frequency continously or 2 Frequencies X and Y, either continously or timed (selectable), The output needs to be offset by 0.2 Volts, running on a 9 Volt Battery. The output has to be a square wave with 50% duty cylcle, only positive potential. The choice of modes as well as the power swtiching should be done in push button technology, as the user interface will be a membrane switch keypad with build in LEDs to show mode. Our goal is to design this without the use of expensive microprocessors. If you do not think this is possible on non-digit...

The design/fabrication of a simple, approximately 70mm in diameter, round printed circuit board for 12v LED light. Board will require pos/neg connectors of some kind located around the outer edge at 45deg. intervals -- 8 pairs of connectors total -- and will include an LED component in the middle. The connectors will be used for the simple attachment/detachment of wire leads. Also will need to design/specify/fabricate the wire leads -- 2 conductor, 20-24 gauge, with terminations to attach to printed circuit board. Terminations need to be as small as possible.

I am looking for someone to develop a stand alone ECU and dash system specific to personal watercraft and as the header depicts for the 3 cylinder Rotax supercharged engine and siemens ecu unit. I am looking for someone to develop hardware and software to enable end users to modify settings within a PWC environment. Initially on SIemens type ECU's. This unit must be a plug and play type unit into the original engine harness and wiring variations range between the models from 2004 - 2009. I can supply pin outs and harnesses as well as ECU's to test or to obtain maps from various years. These engines are stressed, with over 400hp being pushed out of these with superchargers and turbochargers, the main unit needs to be fast. very fast. Looking for someone with some experience in Automotive tuning that understands, timing, knock control etc with the ability to write or code a easy GUI for the end user. some basic requirements *ability to run up to 4cylinders *additional 16 digita...

DESIGN OVERVIEW To supply design blueprints to a prototype manufacturable stage, giving full details of specific component parts for two low energy use stand alone pairable transmitter & receiver components. Each with their own replaceable battery power source that can be paired on a deliberately restricted short range (approx 10 metres), using a suitable wireless signal technology. TRANSMITTER Needs to be able to turn ON/OFF. The TRANSMITTER only needs to send an intermittent (time preset at manufacture) "I'm alive " type signal once turned on. RECEIVER Needs to be able to turn ON/OFF. The RECEIVER component should start listening once turned on, but should only start 'expecting' a signal AFTER receipt of its paired TRANSMITTER's first signal, (this would avoid false alarms if both devices were not switched on at same time) Once the expected " I'm alive " signal has not been received within a preset (at manufacture) time period , the RECEIVER s...
