Mikey and Suzy chip availability?

Hi,

 

Does anyone know if there is a stock of Mikey and Suzy chips somewhere still?

 

The power distribution inside the Lynx is not well done. If you apply too much voltage from the AC adaptor you fry a Zener diode resulting in too high voltage for the rest of the chips. Mikey seems to work as a fuse in this case. In my opinion it would be better to use a stable 6V power supply instead of 9V as is printed on the unit. The Zener heats up a lot with a stable 9V input and can get damaged in normal use.

 

Fortunately the Lynx seems to be protected for applying wrong polarity from the power supply.

If you actually measure what comes out of a US Lynx power adapter, it is closer to 12 Volts than 9. A Lynx I will die out near 5.5 Volts which is just under 1 volt per cell in the battery pack. That's the point where most batteries are fully discharged. A Lynx II will actually run with less than 5 Volts. This contributes a bit more to the battery life.

I'm currently using my 220V adaptor here in canada (110v) the lynx powers just fine and there's no more risk to fry it. :-)

 

I understand how my friend could burn my lynx I now, I used to have a multipower adapter, he must have used the wrong settings on it (or maybe he swapped the polarities).
