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
Check out these Water Droplets Captured using a High Speed Camera Rig. This system uses an Arduino to activate a solenoid, the solenoid releases a drop from a water container mounted at a specific distance above the table. The water falls at a repeatable rate, at the desired time the system triggers a camera flash. This allows a camera that is focused on the hit zone to capture some
Bil Herd goes through a great Introduction to Analog to Digital Conversion. These days it is very simple to grab an analog reading and use it with a microcontroller with ease. This is because modern microcontrollers often have one or many ADC built in. Not that long ago a would have been needed, this is still the case if a special ADC is needed for things such as high
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
John Ward shows us his new test device. Not exactly a bench mounted piece of gear! This Oil Filled Oxford Welder can be used in cases where you need to pump out some serious current, this is ideal to test to destruction items such as wires, extension cables, plug in connections etc. JW has performed many of these tests in the past. Photonicinduction has taken a look at the inside of one of these
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
