Twenty Power Harvesting Projects Headed to the Hackaday Prize Finals | Power Inductor Coil

Abstract: A voltage converter includes a high side power transistor coupled to an input voltage node and a low side power transistor coupled to the high side power transistor at a switch node. The switch node is configured to be coupled to an inductor. A slope detector circuit is configured to receive a signal indicative of a current through the inductor. The inductor current is a triangular waveform comprising a ramp-up phase and a ramp-down phase. The slope detector circuit also is configured to generate an output signal encoding when the inductor current is ramping up and when the inductor current is ramping down.

T.I. and Tiny's 22-year-old daughter has opened up to her fans about undergoing surgery to change her eye colour. Zonnique posted a photo of herself on Instagram that prompted a fan to comment asking for advice on the procedure. "Is the eye color change worth it???” a user asked, via Bossip. “Thinking of going to Kenya and getting it. I have done my research but it will help if u can tell me your experience.”

It was formed a few months after a massive blackout in November 1965, when a transmission safeguard malfunctioned near the Niagara power plant, hitting Ontario and the Northeastern U.S.

Which is precisely how I came to purchase a two pack of Bluetooth Low Energy (BLE) “trackers” for the princely sum of $10 USD. I didn’t expect much out of them for $5 each, but as this seemed an exceptionally low price for such technology in a brick and mortar store, I couldn’t resist. Plus there was something familiar about the look of the tracker that I couldn’t quite put my finger on while I was still in the store.

With this agreement, LaZer II will include SurvalentONE FLISR and Loss of Voltage (LOV) in the bundle and LaZer III will include FLISR, LOV, and Distribution Power Flow (DPF). These solutions detect faults and low-voltage issues, isolate the feeder sections, calculate back-up feeder capacity, and create switch orders to automatically redistribute and restore power flow. This can have a dramatic impact on reliability metrics. For example, Survalent FLISR has helped one utility reduce SAIDI by 46.9%, SAIFI by 38.7%, and CAIDI by 13.1% after one year.

But the yard is actually owned by Hydro One, whose duty is running the high-voltage lines that criss-cross the province on steel towers.

FIRST SEEN Examples of companies that may be originating a patent in the region for the first time, according to Patent Index.

This is “shit, there are no hardware hack articles to steal from dangerous prototypes today! Quick, write up a recap of Wikipedia and post that!, People hate dead air / no updates….” type of article.

The collection consists of House Lannister, House Stark, two House Targaryen colorways (black/multi-color and white), White Walkers and The Night's Watch.

Keep in mind that a lot of the “flying capacitor” style charge pump MOSFET drives can’t do 100% on duty cycle, since they need the off time to charge the cap.

I loved rewiring the Goofy Light also — but I can’t tell you how many times I got “bit” by the power supply when I tried altering it while running
