Steam Resonator

Ethan Crowder STLs ; Gcodes ; .STEP Files

The following .STEP and STL files are from Memo WFC 423-DA. The .STEP files have been provided for CNC machining. STLs are for 3D printing. Discrepancies were found with Stan's original dimensions. A 3D printed model was built and the .STEP files were modified...

Steam Resonator (Memo WFC 423-DA)

Ethan Crowder PCB Gerber Files

The PCB replica is provided below. All components are through-hole (THT) in this revision. Unfortunately, the winding ratios aren't provided in the WFC 423-DA. Experimentation will be required.  A circuit analysis document will be coming a later date.   PCB...
