  • Coffee Counter with Wia Dot One, Button and TFT Screen over 1 year ago

    I am not trying to be disrespectful, but as I was going though this, the one question I kept asking myself was: "what is a coffee counter? and what is its use if you have to be there physically to press the button?" I guess this is a generic counter for anything you want to count, but I could think of more logical uses, like a replacement for the mechanical counters some people use for statistical purposes (counting traffic or visitors to some public place).

  • Flat Panel Switchboards about 2 years ago

    Hello Kirthik,
    I am interested in home control, so I watched this post with interest, but while I was reading it, I couldn't help but wonder at some things:
    - In the introduction, you gave 'smaller footprint' as one of the advantages; but if you use 2 transformers as described, along with all the electronics, the whole switch is rather big...
    - If I understand it correctly, you are using 12V AC to switch the bulb; does that mean that if you want to build this the right way (with diodes that can stand the 230V), that you use a 1:1 transformer? Or could you leave out the transformer altogether?
    - You use a 'Philips Hue' bulb as the load. Why? I have these bulbs myself, and they are meant to be used with the wireless Hue controllers, without the need for 'hard switching'. For me it confuses the issue, I expected it to be used for 'dumb' loads, such as simple LED bulbs or older fluorescent bulbs.
    For my own installation, I used 'solid state relays', these can switch AC loads, and use a 3-24 volts DC input. They switch on the 'zero-cross' moment, so there is no danger of surges or sparks. Example: With this, you could use the same interface using the Arduno and TFT-LCD, but with considerable less power electronics.

  • 3D Printer Thermal Runaway Watchdog / Thermistor Tester over 2 years ago

    Nice project! Maybe you could add all the components in the list in the beginning, and show some more pictures of how the inside is wired up.
