I need someone who is capable of designing and laying out an embedded wireless mode, similar to the Metawear project on Kickstarter but with additional features. Reference:   [obscured]  /projects/guardyen/metawear-production-ready-wearables-in-30-minutes Hardware outline is as follows: - Ultra-low power embedded microprocessor - Bluetooth 4.0 (BTLE) transceiver - Touchless proximity sensor - Embedded ~1yr power source - Embedded GPS module The proximity sensor shall be capable of detecting human presence to a distance of about 10cm, self-calibrating and calculating a simple boolean state. The proximity trigger is expected to continue returning true as long as a body is in proximity, for as little as a few minutes to many hours of presence. All hardware shall be benchmarked to sample at regular intervals, and the power supply should last a minimum of a year with regular use. Microprocessor is optional if BTLE solution can execute code of your d...

Hi I'm doing exactly the same project (  [obscured]  /underground-cable-fault-distance-locator ) The only problem is that I need to replace the 8051microcontroller and ADC with the best microcontroller that it has ADC in it and it will do the same job?! The microcontroller I'm using is AT89S52 and outside ADC 8 bits ,single channel IC and take one analogy signal as input I need to replace them with a microcontroller that has built-in ADC, from ATMEL that is the same as AT89S52 but has ADC built-in

I have an original clock that i would like to replicate. The inside timing is controlled via a receiver signal (see picture attached). I have the diagrams and everything. It is in german and if need be i can have it translated. Your job would be to replicate the inside workings of the clock. The outside design will be different. How do I contact you to discuss the job Ein Uhrr mit Funk möchtee ich nachbauenn. Anleitung ist dabei. Wir möchten ein Prototyp bauen (also innerlich das gleiche aber anderer Design) Ich werde es Ihnen eventuell schicken. Wie kann ich Ihnen Tagsüber am besten erreichen?

This may be a bit of a reach but?..We are looking at out sourcing our sales and estimating. We are a small electrical contracting company in need of a sales and estimating time for a limited time. We would require lead generation for our services within a two hour travel radius. We would need lead to meet calls which one of our staff would follow up on to promote our services and possible projects for quotation. Then we would need assistance with estimates using our labour rates. The estimating process would require a detailed material list that we would then send for pricing. We are active in the Residential market both new single dwelling and large multi dwelling markets as well as the photovoltaic installations primarily microFIT. We are also interested in opening other market possibilities such as fixture re-lamping or upgrades for large factories and facilities quants approximately 40-80 Fixtures per project.

I need to automatically configure AutoCad drawings based on a "configuration list" of sizes and options created in an excel spreadsheet with data for the drawing stored as a data base on the same excel spreadsheet. I wish to manipulate "image blocks" or drawing layers and text on a "default" AutoCad drawing based on cell data in excel. Please see the two attachments. The 2D drawings are ELECTRICAL ladder logic diagrams.

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.

I need someone to work on an existing CAD file and make it more 'marketable' I need the the following layers to be added to the plan (I will just hide the previous version of the below layers). *suite #s added to each room *furniture layout *updated electrical layer (for outlets) *updated phone & internet jack plan **also need the plan 'cleaned up' - remove / black out any non essential items with regards to marketing (i.e. mechanical rooms, building hallways, etc) Once accepted, I will upload a PDF of the above floorplan - with handwritten markups of the above. Floorplan has 50 rooms about 10 x 10 each. Any other suggestions to 'spruce up' the floorplan and make more presentable to potential buyers would be appreciated.

Hello, I was wondering if you could create an electronic device for me? Unfortunately my knowledge of electronics is somewhat limited however; I have taken a video of the device to show what I am after.   [obscured]  /watch?v=NJKehBVTD7s Some Info: The EMP uses 10 wraps on the large coil and 100 wraps on the small coil. It uses 6 x 3.7v lipo batteries. The pulse timing can be changed via a button on the side. I would like to be able to charge the batteries from a dc jack plug. I am interested in just the PCB and components (no coil, case or batteries). I am after about 20 making for now. Would something like this be possible to make? If a pre-set chip with timings is not do-able could an alternative like a potentiometer to control the pulse timings be created? Unfortunately, I don't have a device I can send you as it was broken when it was taken apart by another company. If it makes it any easier I can call you or contact you through Skype etc. Many thanks, Robert Hetheri...

Hi I am trying to gain a deeper understanding of how a pre amplifier works. I have an operational knowledge using microphones but I would like to modify or even design my own at some point in the future. Before I get that far I would like to get some 1 hour long lessons over Skype or anything like skype covering the signal flow in a pre amplifier and how resistors, capacitors, op amps, transformers and other electronic components might change the original signal. I would also like advise on surface mount soldering and what equipment I should by for my first preamplifier. Of course this type of understanding will take a while and I would first like to start with 10x 1 hour long lessons. No pressure, I'm sure your not a teacher by trade and teaching over the internet will be hard, but I'm sure you could help my basic knowledge and become friends. My name is dennis and I live in Australia. I'm 28 years old living in Darwin with a pretty fast internet connection.
