An alarm that detects specific types of events (details provided when contract is signed). The alarm will use 3-5 sensors (commercially available) and will detect that a specific sensor output has passed a specific threshold and will sound an alarm and also show a visual indicator of the type of event that has taken place (based on which sensor crossed the threshold). The candidate will also need to choose the parts for the system (with our guidance) that will meet (or exceed) our quality and cost goals. Finally, a number of working prototypes will be built.

Hi, I need a circuit board designed and code written for a device that will transmit a weight over GSM to remote servers. The signal coming in will be that of a load cell. I would like the inputs from the load cells to be intrinsically isolated if possible as well. Once the signal is received by the Micro controller, it needs to be sent by GSM. That signal will be sent to a remote server and a web application will use the data to provide customer specific information. The unit will be able to take from 1-10 inputs from the load cells for now, depending on the application. Some Digital outputs from the controller will also be transmitted for alarms. The unit will need to be battery powered, with battery level indication also transmitted. I was thinking that readings from the load cell could be stored up and every couple of minutes sent to server to save on battery life. The project is in South Africa. So, I will need controller, modem etc. to be freely available here. I would prefer...

Requirements: 1. Thermal control of 2 resistance heaters with thermocouple feedback. May include Fan control also for cooling. 2. Toggle 8 LEDs on/off 3. Convert 4 analog signals to digital value. Will require some on board signal conditioning. Signal source is a photo diode or similar type device. Signal will need to be free of noise. 4. Battery powered - will need a battery charging circuit 5. Processor - TBD 6. USB access 7. Bluetooth capable - will need to control the hardware via a mobile App. App development will be done separately. Primarily looking for hardware designer at this point. If the same individual can do the firmware, then we may also engage them on the firmware side. Otherwise, we have our own guy we often use.

Camera Module ( optional ) 9. Magnetic stripe reader ( optional ) 10. Barcode reader (optional ) I can give reference specifications of the product. I can also give a ready mould for the product which we can make use of. The firmware for application will be developed by another team, you only need to give test code which shows working of all sub module. By optional we mean we can add these modules if required in final product or can exclude that. The system design though should consider the same. I will require separately cost of making 1 prototype unit as well. So the bid should include 3 component: 1. System Design cost 2. Prototype...

The goal is to make it easy to track how much time people at desk jobs spend actually working and how much time they are distracted. So, I need a design I can send to a manufacturer of a clock with two digital clock displays, one above in green print labeled "work" and one below in red print labeled "idle." There will be two buttons. One large button should be to switch from work time to idle time and visa versa. When pressed, whichever timer is currently running will pause and the other timer will resume counting in increments of seconds. There should be another section of the display that counts each time the user switches from work to idle. The other button will reset everything to zero.

I require assistance with creating a PoC device that can listen in on a specific RF signal generated by a medical transmitter (attached to a constant glucose monitor), decode that data and store it. Ideally, the device will be based on a Raspberry Pi, although I will be happy to accommodate other possibilities. The system needs to: 1. Be able to listen on several frequencies (868.35, 916.5 are two I am pretty certain need to be supported) 2. Capture a very short signal (a few milliseconds) coming in at fixed intervals (e.g. every 5 minutes). 3. Decode signal (which should be unencrypted), and save its digital content The device emitting the signal is this:   [obscured]  -diabetes.com.au/wcm/groups/mdtcom_sg/@mdt/@ap/@au/@diabetes/documents/documents/contrib_107985.pdf (fcc db:   [obscured]  /oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&RequestTimeout=500&calledFromFrame=N&application_id=701227&fcc_id=OH27703) (and belongs to my 5 year old son, wh...

Looking for an electronics engineer who could design and prototype a PCB for a 2.1 digital audio system. Experience with class D amplifiers and Bluetooth modules are required. Some experience with 3D modeling and production is a plus. Evaluation and devkit boards, as well as other parts will be provided to you as necessary. You will build a working prototype and eventually prepare the final design for small batch PCB production. You will work with our industrial designer and also myself (I will do software, product design and project management). This is a personal project with a prospect of going mainstream, possibly through Kickstarter. Currently relies on personal funding. When submitting a proposal, please describe similar work done in the past. Tell me about your musical preferences in a few words as a test that you read the job description. Thanks!
