ITMD3

The 3rd edition of ITMD was released on 1 Dec 2024. With a larger format (7x10) than ITMD1/2 (6x9) and over 600 pages it has about 250% more content. About 80% of the book is re-written and none of the projects from ITMD1/2 were carried over. Instead of fully documented projects with PCBs, BOMs, and source code, ITMD3 has example "designs" for which all documentation has been moved to the ITMD3 support forum. This offers more flexibility in upgrading or correcting the designs....

This is the support section for the 1st Edition of ITMD.

3. Page 100 - First derivative should be dX/dt = Aw cos(wt), and second derivative should be d^2x/dt^2 = -Aw^2 sin(wt).
4. Page 110 - The Raptor schematic
