This project is definitely not small potatoes — three barrels loaded with spuds and charged with propane! Two PIC microcontrollers handle the User Interface, Azimuth and Elevation Aiming and Fire Control functions. Aiming is controlled with a joystick. The Fire Control subsystem verifies a projectile is loaded in the selected barrel before injecting the controlled charge of fuel and that the barrel is armed before firing. It doesn't verify the operator's age, sobriety or aim — that's your responsibility. The chips will fall where they may. Watch the video!
Because of the increasing ubiquity of wearable technology, it would be easy to think that design of wearable devices is routine and involves common design and engineering knowledge. Missed efforts in development will be remembered once the devices are used in the field
This grab-bag of new fasteners and adhesives work with a range of materials they can attach to, as well as a wide variety of applications. Several are for use in consumer applications, such as wearables or other compact electronic assemblies, and some of the adhesives have extended service temperature ranges and cure at room temperature.
As governments, associations, and NGOs around the world seek to protect consumers, national and regional standards are becoming mandatory, challenging manufacturers and making testing and certification necessary for any product developed and brought to market.
