High-Power Control: Arduino + TIP120 Transistor

Up until now, we have talked about working with a lot of low-power devices. Sensors, LEDs, ICs, and the like are all capable of being powered directly from your Arduino, but as many awesome 5 and 3.3v components as there are, eventually you will find yourself holding a 12v solenoid, motor, or light and wondering “How the heck am I supposed to control this from my Arduino?” Well today we are going to talk ab ...

Diverting surplus PV Power

As mentioned on the Contents page, two different hardware platforms have been successfully used to support Mk2 PV Routers. [Update at 7/3/14:  Since writing this article, I have developed a new hardware platform which has been specifically designed  for this product.  The main board has an integral power supply and RF module, and there is a display to show how much surplus energy has been diverted each day. ...

Intersil shrinks step-down DC/DC power module

Encapsulated in a tiny 9.0×6.5×1.83-mm QFN package, the ISL8203M step-down DC/DC power module from Intersil furnishes an adjustable output voltage between 0.8 V to 5 V to allow designers to use one device to build a single 6-A or dual 3-A output power supply. The ISL8203M simplifies power-supply design for FPGAs, ASICs, microprocessors, DSPs, and other point-of-load conversions in communications, test and m ...

Power over Ethernet Flashlight

The TPS2378 is an IEEE802.3at (Power over Ethernet) Powered Device controller, featuring internal pass MOSFET for loads up to 25.5W, Type 1 (a.k.a. 802.3af) compatibility and auxiliary power source support. The IC is normally used together with a DC-DC step down regulator to power a network device (the PD) from a PoE compliant switch or injector (the PSE). A proper 802.3at device requires an isolated power ...

Power Laces- the Auto lacing shoe

Also, check out Power Laces: Version 2.0 Why wait until 2015? Inspired by 'Back to The Future II', this project is less 'Practical' than 'Proof of Concept', but hopefully it'll tide you over until Nike comes out with something more polished. This was also the first time I worked with an Arduino microcontroller, and I wanted to get some experience with the little guy. Operation is quite simple- step into the ...

AC Power Theory – Arduino maths

Instantaneous Voltage and current AC Voltage and current continually alternate, as the name suggests, if we draw a picture of the voltage and current waveform over time, it will look something like the image below (depending on what's using power - the current waveform - blue in the diagram below - is what you get if you look at a typical laptop power supply. There's an incandescent light bulb in there as w ...

Yet Another Arduino 110v Power Controller

This Instructable shows you how to build a four-gang outlet box in which each outlet is controlled via an Arduino (or any other TTL level signals). It differs from the other relay boxes in that it uses no circuit boards and has very few parts (one chip and 4 relays). Step 1: Assemble Materials/Review Plan Tools Needed: Needle Nose Pliers Wire Cutters and strippers Screw driver Soldering Iron Multimeter Mate ...

Surface-mount array takes on medium-power lighting LEDs

Cree has introduced a multi-die 500 lm (80CRI, 3,000K) surface-mount lighting LED, aiming to compete against multiple single-die medium-power LEDs in automated luminaire manufacture. The idea is analogous to the way bolt-down multi-die chip-on-board modules (CoBs) are taking-on single-die LED boards in manual assembly lighting manufacture. Named MH-B, the new LED “combines the reliability and manufacturabil ...

Power Arduino with a cellphone

Old cellphones are easy to acquire and they have built in lithium charging circuitry. What a wonderful base for a power supply for small mobile things. I hooked up a cellphone to the arduino with the ability to charge the cellphone when you plug the arduino into the usb port. Please note that this was just a quick rig and as i did not have the correct screwdrivers, does not involve taking apart the cellphon ...
