Looking for a clock build? This DIY Circular Stepper Motor Clock looks like fun and the parts would be very inexpensive. “The idea behind the clock is a circle with a circumference of 72cm (28.3465 inch’s) that ticks at 1cm every ten minutes which means every 72 ticks will equal 12 hours making it a 12 hour clock. ”
Automating crop harvesting is one farming duty that robotics is good at but dealing with animals that are lose in a field is another story. The SwagBot is a robot that will soon be tending to the animals in the field. Via: IEEE Spectrum “SwagBot is designed to “work in highly undulating terrain, for the purposes of supporting farmers in grazing livestock operations,†Dr. Sukkarieh told us. The robot
This might be the time to jump onto the 3D printer bandwagon. The place that provides cheap good quality cables looks to now be the place to pick up a cheap and reliable 3D printer. At $200 it has some features that you wouldn’t expect to see such as a nice full color display to view settings such as platform temperature so you can easily keep your eye on
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
