Hello This is what I need building. I have a battery powered laptop and a battery powered wireless thermal printer. I need to send from the laptop a print command to the wireless thermal printer. I can do this as long as the two devices are reasonably close together. But I need them to be as far apart as can be done. The concept is a bit of a secrete at present so I am unable to divulge more at this point. Note: Whatever you build to make this possible must be a battery powered device. It ideally would be some sort of wireless booster for the existing set up or as I expect a Completely new device built solely to fit the need. It would need to work through walls if possible like a radio signal does. It need not be housed in its own enclosure as I intend to install it in a case once finished. The laptop and the printer have a Com and USB connection should this be needed. I can send more details as you need them. harrydoroba@yahoo.com

We have been using 4D systems miniature "intelligent" displays for prototyping, but they have drawbacks for a commercial product, so we need to have our own design which addresses the two main issues: A) the electronic size is too large - we want it smaller than the screen, so may need hybrid construction; B) the memory is on removable chips which must have video and audio data files loaded through a separate USB adapter - we want a fixed internal memory (say 4GB+) which can load a file using a USB cable. ... We may compromise t a slightly larger 0.97" diagonal, but we want the smallest electronics possible to support the screen. The product should, in essence, be an MP4/MP3 player with a small rechargeable (e.g. coin) battery.

Requesting development of a configurable set of autopilot actions triggered in response for certain specific detectable events, Windows, Linux, Android or iOS based (need to figure out the best/easiest option). In sum, software for mobile device to control flying remote-control device (drone/quadcopter/UAV) under predefined circumstances, and send simple commands to said device's propellers (like full throttle in certain direction). UI, concept of function, action-reaction map aspects already covered (any aditional ideas are welcome for discussion).
