    Note: I'm looking for developers that have previous experience with GreenPak ICs I have a sensor that consumes ~300uA at 3.3v and I need to reduce it's power consumption by duty cycling it. The GreenPak design will need to power up the sensor, read the differential analog output, store the number of changes in a counter then power down the IC. The counter will be available via I2C for an external CPU.

    Hi We are building animations for our client video presentations and social media. The animations could potentially feature a 3D model of a product (reviewed here: ). We would like to bring the model into After Effects to animate using Video Copilot Element, so the top, bottom and 9 sections would be objects that can be animated individually. We would like an idea of costs for producing the model so we decide whether to animate in 3D or something simpler using photography in After Effects. We will be able to provide the actual box and the deadline would be end of February. If there’s any further information you require please let us know. Many thanks Steven Horne
