We are paying for written application notes based on our configurable mixed signal ICs & integrated power switches. These parts are very versatile so there are many applications that they can be designed for. The application note should be a 1000-3500 word technical white paper describing an application and how it uses the SIlego part. Writer will be responsible for generating the content as well as writing the app note. · 1k-1.5k word manuscript + 2 figures: $750 · 2k-3.5k word manuscript + 3 figures: $1,500 We have many topics that we can suggest for this or you can suggest your own for approval. Here are some examples of app notes that were done in the past: http://www.silego.com/softdoc/app_notes.html Please contact us if this is something you would be interested in doing.

We are looking to develop a sensor that would help people practice their service toss in tennis. We are thinking there would be a sensor you could place on the ground and turn on and a sensor you would wear on the wrist of the tossing arm. When the ball goes outside of the set boundaries the sensor would alarm. We need a for the user to set parameters of the sensor boundaries based on their height.

Need a circuit design schematic with component details and explanation of how the circuit works for LiFePO4 Battery Charger & Battery Management System. There are many open source designs available on the internet. Most of these are based on dumping extra charge to resistors for balancing each cell. We would prefer if there is a more efficient way to charge and balance the cells. The details are in the attached document. If you have existing design/s close to our requirements, that would work as well. Please let me know if you have any questions. Thanks. Vijay

Hi! We are developing a new a new Bluetooth headphone and need to find an experienced engenieer who can help our factory to find a solution around app control. We want to develop an app where the user can adjust the sound volume, bass, discant etc through the app instead of pressing buttons on the headphone. Our headphone will also have some more advanced functions such as multi channel intercom and noise cancelling functionality. We want the app to support that kind of adjustments and options too. We are looking for someone who can help our factory to find the right chipset and software to be able to control the headphone via the app.
