Flickerbot

Periodically, I have a need to leave my desktop computer Krista switched on for a long time. When she render animated 3D scenes or download something big from internet. In this case, I’m just turning off the monitors and go to ride a bicycle. And to make it clear to my families that Krista is working and not allowed to touch it, I did a little flicker-bot. This is a small semaphore on a monitor, is powered by usb-port and discourages casual passers-by. I remembered the youth and the first lessons in a pioneer electrotechnical club, found the necessary electric parts, tools and scheme of astable multivibrator. Don’t worry, it’s only a simple circuit with two transistors wiring, not what you think.

 

…aaaand, meet the Flickerbot!!!

 

 

So, what I needed to create it?
As a basis for the wiring I took an old plastic internet-card from dial-up era:

Flickerbot

Also need a soldering iron, rosin and solder:

…and glue gun:

…and some other simple instruments:

Cheap сhinese tester very helpful,
but we can cope without it:

Of course we also need radio components.
Electric scheme you can found at the end of this post:

Some nice retro transistors photo:

Also you will need unnecessary usb data cable:

Everything is simple — punch holes in plastic card,
insert the radio components and assemble circuit, voila:
Flickerbot

Use glue gun to attach some details like variable resistors,
tumbler switch and usb plug.

The Flickerbot!

Here is electrical scheme, I replaced a pair of static resistors with variable resistance, they began bot ears. You can also experiment with values, there are many schemes with values calculations in web.

      Thanx, UnTonik! Also there was one another version of Flickerbot with powering from AAA batteries.

    Ну нада же )) кт-315 а пременники там нафига? Антураж?

    • Kontramax says:

      В общем да, это же уши, как же без них… и еще ими можно регулировать частоту моргания

    What is this application that is shooting?
    Name pls or link :)
