MIDNIGHTWORKS / PLAYGROUND

A little code, a little spark.

Forms Tinker for Windows. A free electronics playground with circuits, Arduino, Python, local SPICE analysis and connections to the outside world.

1. Download and extract the entire ZIP.
2. Open Forms Tinker.exe. It opens a local browser workspace.
3. Try a starter or make your own. Save a portable .formstinker file to keep it.

No account, administrator installation or development tools required. Python, Monaco and ngspice are bundled locally. Keep the Sources, Engines and notices folders with your download.

Simulation uses the clearly identified runtime for each language and part. Hardware connections use a port you explicitly choose in a browser supporting Web Serial. Simulation never sends to hardware; universal firmware flashing and PCB manufacturing are not included.
