2 days ago · Early in 2011 it became clear that open-source micro controllers had the potential to replace expensive commercial sensor units with cheap cheerful DIY equivalents -provided someone was willing to dedicate the time. In January 2014 we started a small blog recording the development of a simple water flow sensor using the Arduino platform. The project has grown since then and those crude
· A federal prison in Texas has an ISO 9000 certified electronics recycling operation. Inmates tear apart the items and separate the parts. The operation actually makes money.
· A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit s basic function is to interrupt current flow after a fault is detected. Unlike a fuse which operates once and then must be replaced a circuit breaker can be reset (either manually or automatically) to resume
Alibaba offers 4 314 circuit board recycling machine products. A wide variety of circuit board recycling machine options are available to you such as warranty of core components local service location and key selling points.
Brief introduction. circuit board recycling equipment also known as waste circuit board recycling equipment mainly the dismantling and recycling of used appliances computers and other types of waste with PCB waste electronic products. In order to extract the metal in order to achieve a metal recycling process . There are many types of waste circuit board recycling equipment on the market
Phase. Phase is used to describe the two main types of alternating current (AC) electric power produced by a utility generator or UPS system. Single-phase power includes a single AC waveform making single-phase equipment ideal for lower power density applications with per-rack power consumption levels up to approximately 2.8kVA (120V) 5kVA (208V) or 7.4kVA (230V).

A PIR sensor measures infrared light that is reflected off moving objects that emit heat. They are commonly used to detect movement of people and animals to trigger alarms and security lighting. Available in a range of styles for different usage areas indoor and externally with pet-friendly and smart technology options.
A high power factor allows you to connect more equipment to each UPS system and circuit. While a 10 000 VA UPS with a 0.8 power factor will support an 8 000-watt load a 10 000 VA UPS with a 0.9 power factor will support a 9 000-watt load an increase of 1 000 watts without a corresponding increase in circuit requirements.

· Port Manteaux churns out silly new words when you feed it an idea or two. Enter a word (or two) above and you ll get back a bunch of portmanteaux created by jamming together words that are conceptually related to your inputs.. For example enter "giraffe" and you ll get back words like "gazellephant" and "gorilldebeest".
· This article describes a simple cost-effective and scalable approach to fabricate a triboelectric nanogenerator (NG) with ultrahigh electric output.

· I have noticed that when I power this module from Vcc at 3.3v it draws around 89 µA. But according to the datasheet the RTC should only draw 2 µA on average when powered from Vbat. (1µA baseline plus about 500µA for 100ms every 64 seconds when the crystal is doing temperature compensation) Nick Gammon found an elegant way to power a DS1307 by connecting Vcc to one of
