If you are in need of a great battery charger or want to learn some more about how a dedicated power management controller gets configured this project by K.C. Lee is worth a look. It uses the Microchip TC4426A Power Management IC to manage the charging and analyzing of two batteries. “This is a useful tool for determining the charge/discharge characteristics of batteries which help you reuse or for
When the power fails and you are stumbling around the house your flashlight batteries will inevitably be dead. A simple solution to this issue is to use a flashlight that doesn’t need batteries. With low current LEDs you can dynamically generate the power you need to light your path by just a few shakes. Of course you can purchase one but building one is much more fun! “Materials needed: Small
When you are shooting handheld video you will usually get lots of camera shake. The solution is closer than you think, Matthias Wandel demonstrates how some common things that you already have laying around can dramatically improve the video quality without spending thousands on something like a steady cam rig.Â
CNLohr has been playing with the popular addressable WS2812B LED lights and the powerful (and cheap) ESP8266.
Pi is a very interesting number that comes up in many formulas. Did you know that you can calculate it using a swinging pendulum?
This is a great looking lamp that allows the users to interact with the lamp colour in an interesting way. “Colour injector is an interactive multi-coloured lamp designed as a physical expression of the way red, green and blue light are used in digital interfaces to create a full spectrum of different hues. Syringes suspended below the lamp are connected to another set inside the body using clear tubes
Instrument clusters are no longer truly mechanical analog gauges connected to sensors directly in your car. The car is a big sensor network which communicates to the dash board instruments. This means that you can re-purpose them like Esko Haas has done with his 2003 Fiat Stilo closk. If you want to build on his work you can find his code here. “By the way, I’m using this board for connecting: http://www.ittgroup.ee/en/mikrokontrollerite-arendusplaadid/545-avr-tlcd-128can.html It’s compatible
