23 OCT 2025 - We are back! If you have been following us over the last few years, you will know that the last 2 months have been rough. We website was practically not loading. Sorry for the mess. We are back though and everything should run smoothly now. New servers. Updated domains. And new owners. We invite you all to start uploading torrents again!
Are you looking for tools like Multisim, SPICE, LTspice, Proteus or Altium? That's great! PROTO is an real time electronic circuit simulator which means you are able to setup a circuit with various components and simulate behaviour of the electronic circuit.
During simulation you can check voltages, currents and many other variables. Check signals on multichannel oscilioscope and tune your circuit in real time! You can also use PROTO as logic circuit simulator and perform digital electronic analysis!

+ Animations of voltage values and current flows
+ Adjusts circuit parameters (like voltage, current and other)
+ Four-channel oscilloscope
+ Single play/pause button to control simulation
