I'm looking for someone that can redraw schematics in Altium. I use a rather obscure schematic/PCB tool called DipTrace, but some of my clients want their schematic in Altium format I can provide you schematics in either PDF format, or ASCII. There is no way to do an error-free conversion from DipTrace to Altium so the schematic will need to be completely redrawn. What would your rate be for redrawing a schematic that included 480 pins, 185 components, and 110 nets? This is a typical size schematic for what I typically design. I prefer those willing to work on a fixed price basis. I have this initial job posting listed as hourly since I'm not sure on the fixed rate amount. I don't have a schematic ready right now to convert, just looking to line up someone that can convert my future designs.

I am looking for a rock star electrical engineer who is familiar with the STM32F4 MCU family to review the Altium schematics files for our product. Your own designs must always work as expected the first time, and your review must ensure the same for our product. The schematics include 10-15 modules with around 20 distinct ICs and many discrete components. I would expect a skilled engineer could do a thorough review in 8-16 hours. I'm looking for someone who can do a more thorough review within 8 hours. I expect the review to be complete within 48 hours after we agree to terms on the job. I'm not interested in working with a project manager or a team. I would need a signed NDA before I can send the review materials.

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.
