Maximize Your Solar Charging With a DIY Arduino Controller

Here’s how to build a buck converter using an Arduino Nano (as well as another 28 listed components) to supply the maximum power that you can to your PV cell. This is known as maximum power point tracking, abbreviated MPPT. Photovoltaic (PV) cells produce different amounts of current and voltage depending […]

Programmable Lithium Charger Shield for Arduino

Surely you need yet another way to charge your lithium batteries—perhaps you can sate your desperation with this programmable multi (or single) cell lithium charger shield for the Arduino<! Okay, so you’re not><em>hurting</em> for another method of juicing up your batteries. If you’re a regular around these parts of the interwebs, you’ll recall the <a href="">lithium charging guide</a> and that <a href="">rather incredible, near-encyclopedic rundown of both batteries and chargers</a>, which likely kept your charging needs under control.</p> <p>That said, this shield by Electro-Labs might be the perfect transition for the die-hard-’duino fanatic looking to migrate to tougher projects. The build features an LCD and four-button interface to fiddle with settings, and is based around an LT1510 constant current/constant voltage charger IC. You can find the schematic, bill of materials, code, and PCB design on the Electro-Labs webpage, as well as a brief rundown explaining how the circuit works. Still want to add on the design? Throw in <a href="">one of these Li-ion holders</a> for quick battery swapping action.</p> <p>[via <a href="">Embedded Lab</a>]</p><br />Filed under: <a href="">Arduino Hacks</a>, <a href="">Microcontrollers</a> <a><img src="" /></a> <img src="" />

EMW kick-starts JuiceBox, a $99 Level 2 DIY charging station

Electric vehicle charging stations aren't cheap: one of the most affordable Level 2 (240V) units sells for $450 and only supplies 16A. Electric Motor Works (EMW) -- which is best known for its electric conversion kits -- wants to change this with JuiceBox, a 15kW Level 2 EV charger that costs just $99 in kit form (plus $10 shipping). The device, which is launching on Kickstarter today, supplies up to 62A and operates on both 120V and 240V. It's built around an Arduino microcontroller and EMW is making both the hardware and software open source.

But wait, there's more! The company is also crowdfunding a Premium Edition of JuiceBox ($199 in kit form) which adds time-of-day charging, a color LCD, ground-fault plus output protection (for outdoor use) and a unique enclosure (hopefully as funky as the one in the picture above). While the DIY kits only require basic assembly and soldering skills, you'll be able to buy fully assembled versions for $100 more. At $329 (shipped), a ready-to-use JuiceBox Premium Edition undercuts other similar charging stations by several hundred dollars. The catch? You'll have to supply your own cables (or buy them separately from EMW), including one with a standard J1772 EV connector.
