Build Your Own iMouse FM Transmitter. Plans Included!

Raymond, who built the iMouse from our last post, was kind enough to send us the plans including a schematic. We had quite a few readers interested in how to build one so here's your chance. Give it a try and be sure to send us pics and stories of your attempts.

Raymond's plans (of which the image above is the schematic) follow:

Build your own iMouse

C7 ...............................10 pF ker.
Resistor:
R5 Trimmer.................10 kΩ
R6 .............................. 10 kΩ
R7 ...............................2,7 kΩ
R8................................1 kΩ

Spool L1:
Use a 10 cm long Silver wire.
The diameter inside the spool should be 3 mm.
7 winds total
Length of the spool should be 15 mm (f-g)
The antenna is connected to the spool at 3mm from f
