IAMBIC85: "An Ultra Simple Iambic Keyer with Speed Pot"
- At 2019 Jun 29: Now for ALL ATTiny85 (45/25 and for a 13, too !)
No "misteries" here, in only 244 bytes of code !
-
Speed: From about 12 wpm to 40 wpm
-
Iambic Mode: Iambic "B" ( Yep ! Accu Keyer, you bet... )
-
Sidetone: 500 HZ (fixed)
=> At 2019 Jul 18: Changed to 500 HZ pitch (that's more "real World" CW !)
- DC Source: 5V @ .03A ( 30ma )
=> At 2019 Jul 18: Using an external 78L05 (better Speed Pot range)
I loved to put all on base of my Vibroplex Iambic Key
My version was done with an ATTiny 13 (not an ATTiny85 Board as in Schematic)
