Wearables are devices that incorporate and interact with different parts of our bodies and perform a specific task. The tasks can be to improve our health (count steps, heart rate etc.) or to make our life easier (GPS, smartwatches etc.). Technology industry has dominated the wearable...

Boris Landoni @ open-electronics.org documents his UV index detector. It measures solar radiation and visualizes the corresponding value on the integrated display of a miniaturized Arduino, in order to tell us when to expose ourselves to the sun… Open Source UV Index Detector -...

Sunburn Monitor is a UV monitor with sound-based indication. It calculates the max sun exposure before sunburn based on your skin type. The project was published over hackaday.io by [Quarterturn]. It's based around SI1132 light sensor from Silicon Labs. SI1132 is a UV index and...

A ceramic-based UV LED, the VLMU1610-365-135 from Vishay provides typical radiant power of 18 mW at 20 mA and 50 mW at 60 mA over a wavelength range of 362.5 nm to 370 nm. The silicone lens of the device enables extremely long lifetimes of up to 25,000 hour, compared to typical...

Here is a countdown timer for UV exposure lamps @ cuteminds.com Here follows a simple count down timer useful for the production of pcbs using photoresist and UV lamps. We have used a pic 16F887 Microchip microcontroller; there are no particular reasons, we have simply used the...
