It’s my first post in English on this blog, just to get to the broader English crowd of the maker world. I’ll present my latest project, the fifth iteration in my quest to create a remote control for my DSLR. There’s a night-mode, where all the LCD turns red, useful for astro-photography, when you need to be able to look at it without compromising your acquired night vision. The interface is limited to a single rotary knob you can push to validate your choices. It remains easy and intuitive to use even when it’s minus 20°C and it’s pitch black. The output is a standard 3.5mm stereo jack, you can use different cables to control different brand of DSLRs. [ ]

Simpleclock is an easy to assemble attractive 4-digit 7-segment LED display clock with temperature and alarm function. It is available in three display colors: Red, Blue and White. It comes as a kit of through-the-hole parts and can be soldered by any person with basic soldering experience. An attractive acrylic stand is included. [ ]

Summertime is holiday time but who will be looking after your delicate houseplants while you are away? Caring for plants is very often a hit or miss affair, sometimes you under-water and other times you over-water. This design seeks to remove the doubt from plant care and keep them optimally watered.  The principle of the circuit is simple: first the soil dampness is measured by passing a signal through two electrodes placed in the soil. The moisture content is inversely proportional to the measured resistance. When this measurement indicates it is too dry, the plants are given a predefined dose of water. This last part is important for the correct function of the automatic watering can because it takes a little while for the soil to absorb the water dose and for its resistance to fall. If the water were allowed to flow until the soil resistance drops then the plant would soon be flooded.  An Electronic Watering Can Circuit diagram : An Electronic Watering Can Circuit Diagram...
