NOTE: WE ARE ONLY LOOKING FOR FREELANCERS IN THE SAN FRANCISCO BAY AREA. The full description for the job can be found in the attached PDF. Note that the budget posted here and the quote we are looking for is for having our current needs met. Those needs are to: incorporate control of pneumatic control valves into our current electronics box which is composed of a couple adafruit and sparkfun breakout boards with an Arduino; find and incorporate a way to sense the orientation of our device; and modify code so that we have better filtering of speed data coming from the truck, a stall feature that is suitable for the pneumatics system, and better user interface. To get a better idea of what we are doing, check out our website: www.xstreamtrucking.com

The overall goal is to create a safe hand-held system at minimal cost, having enough energy stored to heat a nichrome coil of about 0.9Ω for it to be red hot, for bursts of 10 seconds, around 50 times. Deliverables: Provide a functional unit, as well as a BOM, and schematics. The device is a battery powered heating coil The specifications: • The load circuit has a low impedance, of about 0.8 to 1.3 Ω, it is a small nichrome heating coil • Open circuit voltage output around 12 V/ The voltage output may not be constant due to the low resistance, and will rather have a wide range once connected to a load • Higher than normal power is needed between 10-30W • The battery would provide high currents to reach the required power rating, usually 1- 6A to heat the coil • Rechargeable battery has to be able to withstand low resistance

We're looking for an experienced ARM board designer that has experience from developing a prototype to assisting in production run of quantities in excess of 10,000 units. This posting is for a conversation with someone who has aforementioned skills and experience. We will be talking to more than one contractors from Upwork and the one that we select will get the job of actually designing the product for us. Why we're willing to pay for a conversation: We want to talk to someone who has the skills and experience and can educate us on what we need to know about various stages of embedded System Design and development, timeline, certifications needed and an educated estimate on how much is the final product going to cost in production run of 5,000 to 10,000 units. The ARM board should be capable of running Linux and node.js. Cost is an important consideration for us, so we would like to use components that are reliable, easily available, widely supported, value for money instead of the top of the line. When responding to this post, please include what your hourly rate for this conversation will be and the hourly rate you charge for embedded system development.

We are at the tail end of building the first Bluetooth controlled exercise weight machine. We are seeing some interference issues and stability issues. I'm looking for an RF engineer that has experience in the various methods of RF Signal transmission. If you have worked with RC controllers, Bluetooth, or Wifi on embedded systems, I'd like to get your help. It is our goal to build a reliable and fail safe system. Signal integrity and critical mission protocol would be ideal. Please let me know if you are interested. Check us out on www.flexlinefitness.com Long term opportunity is also available. -Brandon Chief Product Officer

Greetings, We are currently developing a BLE based proximity tracking device which connects to an Android app and helps user track/find their belongings. It is similar to a Tile or TrackR tracking device but with higher working range and some unique features to enhance user experience. We are using a TI chipset of CC2541 with extender and on-board antenna developed by RadioLand China (Model CC2541PA1). Our board design is done with a firmware in place and an Android app that talks to the device. We have two issues with the app that points to issues in our firmware + app that we need help fixing. These two issues are: - Proximity compass: Use the RSSI, BMA 250 sensor and algorithms to guide the user to the lost item where the tracker is placed. This feature guides the user to the tracker like a compass (left or right, straight or back etc....like directionally more than regular bluetooth tracking of just notifying radius between devices. - The distance calculator between the tracker and app/phone needs to be optimized for accuracy - There should be multiple devices that a user can track so they can put the trackers in multiple things around them We are currently in an urgency to fix the issues and finish the prototype for a demo. Once we demo the prototype, we will have to go into a turning the rigid PCB to a flexible PCB with onboard battery and do production work. So the project will contain a lot of PCB design, firmware design and app work before releasing it in the market. Right now, i am just interested in finishing the prototype for our stakeholders before moving to the next stage. I request interested parties to have prior experience in the exact same application or close thereof so we can start troubleshooting quickly. Also interested candidates should be prompt in response and providing feedback. We have several prototypes that we can test but the software development in the interest of time will have to be remote. We can consider shipping a device to you if that accelerates the process.

Upworker to do the ffg; 1. Design a circuit with the utilisng the PS25251 sensor (refer to http://www.plesseysemiconductors.com/doc/?id=291766) 2. The sensor should be mounted on specially designed circuit board (with the same footprint of the sensor) 3. The circuit board should have a connector to which a harness connects to. 4. The circuit board connects to another 'motherboard' which has an LCD and MCU 6. Upworker should source a single PS25251 sensor from suitable local supplier (~$10). 7. Circuit to be designed using equivalent components from www.mantech.co.za 8. Upworker should not buy any additional components (other than the PS25251) 9. Supply voltage is 12VDC (should be regulated to supply sensors + MCU) 10. MCU should be a PIC (5V or lower because sensor operates within this voltage) Deliverables 1. Simulation 2. Through hole PCB design (single sided) for the motherboard (Gerber files required) 3. SMD PCB design (double sided) for the daughterboard (Gerber files required). This side should not have the connector as it is the receptor 4. Video of the working circuit 5. Code in C and instructions on how to program using PICKIT 3.
