HARRIS’ ELECTRONICS is developing a prototype set of Smart Glasses. This is not an easy task! You can read about the development challenges here. Thanks for the tip James. “The glasses themselves are based around an STM32F051K8 microcontroller (LQFP32 for easy soldering!). All the firmware is custom written though I got the LCD driver initialization codes from the BuyDisplay examples. The firmware is written using a somewhat “co-operative schedulingâ€
Jeremy Blum built this Custom Word Clock. It has lots of non electronic parts such as the great looking case. Good thing Jeremy is no longer at Google and is now working at Shaper with use of a wood working shop. We have seen lots of word clocks here in the past but the main thing I like with this design is the LED panel based design. Most designs
With the adoption of IOT long runtime on battery power is something that is a huge concern. We don’t mind charging our smartphones daily but if we have a dozen IOT devices in our home we would like them to be invisible and just operate for as long as possible without needing attention. Andreas Spiess has done some research using the popular ESP8266 and a variety of batteries. In his test
It is that time again! There is a new batch of Cornell University ECE 5760 Advanced Microcontrollers Final Projects. If you have done any PID work in the past the FPGA controlled Magnetic Levitation by Gautham Ponnu, Ryan Land, Nathan Spallone should be of interest. They are using a Altera DE2-115 FPGA board to monitor and control a steel ball about 1mm above the position sensor with great accuracy. “The LDC1000
Prometreus has a great concept here. This plane has autopilot and a camera to capture the trip. With a 6 hour 200km range you can certainly cover a huge area. “A SOLAR powered RC plane flies over 6 hours, only powered by the sun. The plane travels a distance of over 200km. It is self sufficient like the solar impulse system. ”
If you do any metal work projects there will come a time when you would like to bond some metal together without using mechanical fasteners. Easiest way to do this is by welding, a spot welder is a type of welder that is simple since there are no welding rods needed. Make it Extreme built this great looking DIY unit. A high current is simply passed through the two metals
When it comes to converting something drawn to a laser etched image there are often quite a few steps needed. Martin Raynsford has built this Drawing To Laser Engraving System to allow him to easily go from drawing to laser etched images by using a bit of hardware and some custom software. Of course you can do this type of thing manually like was done in the Halloween Hanging
