Leapcraft (  [obscured]  ) is looking for a freelance electronics designer who can help with our projects to design electronics for small sensor packs and consumer appliances. The candidate should be proficient in schematic design with low energy system, experience with RF design and BTLE would be an advantage. The ideal candidate should also be able to effectively translate high level specifications as block diagrams and written descriptions into actual electronic design documents. Software type is not a criteria but being able to communicate effectively in English (verbal and written) and in dept understanding of technical aspects and terminology is must. Experience in compact, multilayer PCB design will be crucial and real word understanding of PCB production and assembly process will be good to have. Please apply with examples of schematics and PCB designs as reference.

The attached sketch of a floor plan is the existing, 1,755 square foot, layout of a 1975 ranch house with a~300 sf basement (which is not yet dimensioned but should be added on 7/10-7/11). We are moving a family of 2 adults and 4 children, 6 and under, into this house. Our plan is to enclose the garage to make it into a master bedroom and bathroom (see the adjoining bathroom to the garage), and expand the kitchen into this area, allowing for a kitchen upgrade. A stair case will be added to access the basement from inside the house. We would like to add a garage or detached garage/carport once the garage is closed in, so that cars can still be parked in a covered area. Requirements: 1 - The existing floor plan shall be transferred to a suitable architectural, digital 3d model style (Chief Architect, Arch CAD, etc) so we can get a better feel for what the current house looks like from all angles. 2 - The floor plan shall be modified to accommodate the enclosure of the garage and b...

We run a small music school. We have an electric door lock that opens from inside with a very simple switch button. It's actually 2 wires, that when in contact, causes the door lock to unlock and then the door can be opened. I'm looking for someone to help me to create a small project that consists of connecting a numeric keypad connected to a PC and when a visitor enters a 10 digit code (every student has a 10 digit code) the PC then verifies this code in a database and if it's a valid one, the PC then unlocks the door lock (by connecting or closing the circuit on these two wires for 1 second). I'm a computer programmer but I have no experience with electronics. I'm looking for someone that can build or help me build a solution to this simple electronics project.

Hello, I am looking for a micro switch or sensor based seat belt kind of electronic device. Scenario: This belt will be ON the chair... where a person sits on it. If that person leaves the seat, this device needs to wait for 5 minutes, and if he don't come back and sit on the chair? it should start giving some small beeps are some sounds to bring him back to the seat. The delay of 5 minutes is allowing the person to go and get a coffee or some quick things to do, away from his seat. Few requirements: ? It should be very small and compact micro switches / sensors. (as the person will sit on them, he should still feel the 'almost' natural comfort) ? If required.. The circuit or beeping things can be extended and keep bit far/ under the seat. ? The time delay should be adjustable to give freedom to the user to choose the delay to alert him to come back to the seat. ? Beep /sounds should be pleasant, cool and if possible, multiple musical tones where user can change! (This feature ...

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...

Hi Looking to hire someone to develop this product for me. The product is for me primarily, but I plan to also do market testing and determine if there is a demand for it on the market. If it can be created. The product I'm looking for is a somewhat like these:   [obscured]  /#testosterone   [obscured]  /media/dexcom-seven-plus   [obscured]  -app.com/the-glucotrack/ What I want is a continuous monitor for testosterone levels. Preferably non-invasive - meaning that it doesn't reach the blood-stream or interfere with biochemistry in any way. For example, from one of the other products: "GlucoTrack uses ultrasonic, electromagnetic and thermal technologies to non-invasively measure glucose levels in the blood" I want the same type of product, but for a different biomarker: testosterone. Why do I want this? Because I believe it's a product that can significantly improve people's lives. Especially my own. Testosterone is a good measure of health and well-being, f...

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...
