A research team from UC Berkeley Univercity (Daniel S. Drew, Nathan O. Lambert, Craig B. Schindler, and Kristofer S. J. Pister) has designed and build mini microbot that is capable of taking flight without any motor or moving part. This is all achieved using electrohydrodynamic thrust to provide lift, which is a technique to create air-flow […]

Keysight 34465A & 34470A DMMs offer unprecedented levels of accuracy, speed and resolution. They can measure very low current down to a 1 μA range, enabling their use on very low power devices. The ability to auto-calibrate during the measurement allows the 34465A and 34470A to maintain a calibrated measurement while the instrument may be

Farkle is a classic dice game that only requires 6 dice and a way to write down scores based on the numbers rolled. Even so, this type of game isn’t inherently portable — it would be fairly difficult to play on a road trip, for instance. [Sunyecz22] decided that Farkle would make an excellent electronic game

Just as cats find sitting on a keyboard to be irresistible, so do children find pressing their keys. After throwing some ideas around with other parents, [Peter] came up with the idea of transforming an old AT keyboard into a learning toy by making each key press “speak” its corresponding letter. The donor keyboard is a

There are many schools of thought when it comes to keeping vinyl records clean. It’s a ritual that’s nearly as important as the one that comes after it — queuing up the record and lowering the needle. We’ve seen people use everything from Windex and microfiber towels to ultrasonic cleaning machines that cost hundreds or

With the increase of high integration programmable chips, FPGAs are getting more and more popular. FPGAs has been traditionally known to be generally complex, but a new line of FPGAs have been showing some promise and that is believed that will help increase their popularity. Tiny FPGAs are the next promising thing, they are low-cost

Low-Power Oscillators SiTime Corporation’s general purpose low-power oscillators offer a perfect combination of low power consumption, excellent stability, small size, and fast start-up. Parts are also available in an SOT23 package which offers excellent board-level solder-joint reliability and enables low-cost, optical-only board-level inspection. Now system designers have lower frequency options based on programmable MEMS timing
SiTime presents a family of MEMS oscillators for mobile applications Continue Reading
Monolithic Power Systems has introduced a new synchronous, 4-switch integrated buck-boost converter, the MP8862. The converter can regulate the output voltage from a wide input voltage range of 2.8V to 22V with high efficiency. The converter supports an Iout of 2A. Vout ranges from a 1V minimum to a maximum of 20.47V with a 5mV resolution
The MLX90641 is a 16×12 pixel IR array housed in an industry standard 4-lead TO39 package and is able to accurately measure temperatures in the range of -40 °C to +300 °C. The factory-calibrated devices ensure an accuracy of 1 °C in typical measurement conditions. The high accuracy is further supported by a Noise Equivalent

Soil moisture sensors are cheap and easy to interface with, to the point that combining one with an Arduino and blinking an LED when your potted plant is feeling a bit parched is a common beginners project. But what about on the long term? Outside of a simple proof of concept, what would it take
