Solar energy harvester IC that operates with indoor lighting

Saelig Company, Inc. (www.saelig.com) has introduced the patented Sol Chip Saturn802 Energy Harvester IC – a unique photovoltaic (PV) cell which can produce output voltage levels of 0.75V, 1.5V, 2.25V, 3.0V, 4.5V, and 9V, which existing solar cells cannot do.  The maximum power which can be obtained in full daylight is around 10mW, or 55uW in office lighting, so the Saturn802 IC is targeted at low-power app ...

Tidal Clock

This is a tutorial for making the Tidal Clock. The clock shows the ebb and flow between high and low tide by a rising and falling water level. It consists of an airtight acrylic container that has a front visible chamber and a back hidden chamber. A volume rotates through the back chamber, displacing the water in the front and causing the water level to rise and fall. The rotation is controlled by an Arduin ...

A STUNNING RAY GUN BUILT FROM JUNK

If ever there was a quintessential weapon of science fiction, it would have to be the ray gun. [lonesoulsurfer] built this one-of-a-kind stunner from his impressive collection of junk. It’s centered around a vintage Bakelite soldering gun, a vacuum tube, and a portable stove burner, all of which contribute to the fantastic mid-century look. Inside is a slightly modified version of a ray gun sound ...

A STM32F4 BASED ARDUINO IN THE FEATHER FORM FACTOR

[minh7a6] loves the Adafruit Feather, but sees some room for improvement. First is the matter of 5V tolerance. While just about everything is available in a 3.3v range these days, sometimes it’s just nice not to have to care. The main controller on the Feather is plenty powerful, but its intolerant pins just wouldn’t do so it was swapped for a chip from the ever popular STM32F4 line. Then he wanted bet ...

Improving Wearables with Flexible and Rechargable Battery

Nowadays, there is a lot of technology that implements wearables in fashion, medicine, worker safety, accessories and much more. Many wearables are coupled with uncomfortable charging cables that are irritating for users to handle, some even have big batteries that make wearables a burden instead of an advantage. Statistics show that people tend to abandon this devices after only 6 months of buying them, an ...

Replacing a dead iPhone battery

About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a “this accessory may not be supported” message appeared on-screen; when I unplugged and re-plugged the iPhone to the charger, it didn’t reappear, so I didn’t think anything more of it … until a half hour later, when the iPhone again alerted me, this time ...
