Dear all We are interested in designing, and prototyping and printing a compact embedded system which will comprise of a small hardware unit with the following tasks: SCENARIO A (with button) 1.A device comes with a button. 2.The device also includes a cell phone sim card. 3. When the button is pressed, an SMS message will be transmitted. Optionally a REST API call to a remote server over WiFi or a Bluetooth signal. SCENARIO B (with motion sensor) Same as scenario A, utilizing a motion sensor as a trigger. The ideal unit diameter would be 2~3 cm yet there are physical limitations for designs over 5-8 cm diameter. You may provide similar work samples and related experience in your response. Please provide an abstract hardware cost estimation (prototype/mass production). Please provide further information on the design process you are familiar with (PCB design software, microcontroller of choice, design process, prototyping, testing, etc). An estimation of project delivery time is also required. Please apply responsively. Best Regards

Hi, i am looking for an experienced circuit designer who not only is good at what they do, but also has the passion and motivation to creating something brand-new! We are a young company with a vision and a path to success. We not only want a skilled individual to complete this project, but instead want someone to join our team and create something magical. Our company is based around being innovative and achieving something unique and exciting! The companies main goal is to achieve great customer satisfaction along with a well designed and executed end product. The product we are developing will be a drone that will follow a wristband or clip that will be placed on the customer. We will be attaching a camera on the bottom so the drone will have to have camera stabilization technology. We also want to achieve a battery life of more then 15 minutes and still be light weight. For further information please feel to message me and ask questions. As a team we are looking for a skilled individual who has the skills and knowledge in circuit boards technology. Someone who knows what is needed to create this project and can help suggest the best and up to date technology. We are a startup company and are trying to do something different with drones. Looking forward to seeing what you guys have to offer, thanks for your time and best of luck!

Real-time detection of liquid level in a volatile environment is always a knotty issue. We are working on an intrinsically safe liquid-level sensor system for flammable and explosive environments. Our sensor chain is based on 'Hall Effect' magnetic readings as the sensing element and the measurement of tank levels. We utillize capacitance-to-voltage conversion to achieve the expected output signal. Additionally, the system is designed for intrinsic safety by limiting the energy of the circuit to avoid or restrain the thermal effects or potential sparks. Micro voltage and linked micro circuit chains.

Hello, I am working on a new type of interactive toy that pre-records 5-10 seconds of text spoken to it and then sings this text back in a variety of musical styles (rap, jazz. etc.). The toy must also be able to add random words and phrases to the pre-recorded text, such as "cool", "I love it", etc. Previous experience in software & hardware to record and process sound is required. Contact me for more details.

We are looking for someone with experience in hardware designing and development. We have a sensor which with its amplification circuit produces current between 0-200 milliampere. The amplification board is power by a +/- 5V supply. We need hardware development for the power supply and IoT for the board. The power supply needs to be through a rechargeable battery. First, the current by the sensor is directly proportionate to the PPM levels of the gas it senses. We need the results to be displayed on the system and to be transmitted to an AWS server using GPRS. Then, we need a provisioning for two alarms. E.g. 1st alarm at 2ppm and the 2nd alarm at 5ppm. These alarms will be connected to a hooter and LED lights which will turn on respectively when the alarms go off. There should be provision using buttons to change the value of these alarm levels. The sensors too have some calibrations which need to be done, so there needs to be a provision through which we can set the value of the gas at 0 at that specific current. For e.g, the sensor at 0ppm produces 2.23 milliAmp current. Some other sensor may produce 0.23 milliAmp current at 0ppm. So we can initially calibrate the system so that it shows the correct value. This is our requirement in detail. Please contact me for any queries or clarifications.

I am developing a dynamic lighting system and will need an experienced programmer to be able to code in various customizations within the system. I want to mimic the rise and fall of the sun using artificial light (LED RGB addressable strip) as closely as possible. Therefore on every hour the light will brighten or dim depending on the time in the day. The lights system will cycle through this 12 hour daylight period with 12 different colours depicting the sun and its natural morning, noon or evening light. The light will need an internal clock programmed into it. To track time and produce the right type of light at the right time when it is turned on. Amongst this I would like the user to have some control by developing a phone application to control the colors if they choose to do so. This can be done via a Bluetooth or WIFI connection. control buttons (on/off, bright/dim, color) for the light. The Strips are to be programmed to 6500K blue-rich white light (mid-day sun), to 1800K amber white light (fire/evening light) I need someone who is willing to code all this up! I'm personally not that experienced in this area so initiative will be a plus just run it by me before doing so. Will discuss in full details once best applicant is suited.
