Adding Sensors to Monitor Hive Health
https://www.electronics-lab.com/adding-sensors-to-monitor-hive-health/
by Nathan Seidle @ makezine.com: The Digital Beehive uses Wi-Fi to broadcast a beehive’s weight, humidity, temperature, and battery voltage every minute to SparkFun’s data channel service called Phant. The raw data can be seen here but you can view some prettier graphs of the data here on analog.io (sign-in required). Adding Sensors to Monitor Hive […]
Not a battery, not a cap: Murata’s small energy [storage] device
https://www.electronics-lab.com/not-a-battery-not-a-cap-muratas-small-energy-storage-device/
by Graham Prophet @ edn-europe.com: To meet what the company sees as a gap in the available range of energy storage solutions, Murata has developed the UMAC, a small, high-capacity cylinder-type energy device for use in wearable and wireless sensor applications. Although lithium-ion based, Murata differentiates it from a battery. The UMAC is a miniature device […]
Logic PCB Business Card
https://www.electronics-lab.com/logic-pcb-business-card/
Floyd-Jones designed his own business card using logic circuitry. He writes: The card implements a digital finite-state machine which displays the next character of my last name on a 7-segment display each time the button is pressed. Luckily all 11 characters in my name can be reasonably shown, essentially spelling out FLoyd-JonES. I simulated the […]

https://www.electronics-lab.com/multifunction-biosensorvital-signs-monitor-for-wearables-from-ams/
by Graham Prophet @ edn-europe.com: Sensor and mixed-signal IC specialist ams (Graz, Austria) has applied optical detection techniques to produce a sensor capable of accurate heart rate measurement; the company says its device is the first “total solution for 24/7 heart rate measurement for wearables”. AS7000 is the first in what is to be a family […]
DIY Motorized Combo Lock Cracking Device
https://www.electronics-lab.com/diy-motorized-combo-lock-cracking-device/
Combo Breaker is a motorized, battery powered, 3D printed, Arduino-based combination lock cracking device. It is portable, open source, 3D models provided, and exploits a new technique I’ve discovered for cracking combination locks in 8 attempts or less, but in an even more exciting, automated fashion.

Solar Cells Made Obsolete – 3D rectennas aim at 40-to-90% efficiency
https://www.electronics-lab.com/solar-cells-made-obsolete-3d-rectennas-aim-at-40-to-90-efficiency/
R. Colin Johnson @ eetimes.com: PORTLAND, Ore.–Now before you get all excited by the headline, which is not click-bait according to the researchers, a new kind of nanoscale rectenna (half antenna and half rectifier) can convert solar and infrared into electricity, plus be tuned to nearly any other frequency as a detector. The invention was made […]
