 | | Re: IntelliMouse Ripe for Hacking
|
| I've just got the IntelliMouse Explorer. I had problems at first on my Simpson's mouse mat, but then I tried it straight onto the desk top. It's very good and I have no problems with it at speed. I bought it to play Quake X with, but I haven't had (...) (26 years ago, 25-Oct-99, to lugnet.robotics)

| It won't necessarily fry the chip. L293s (and the TI equivalent) have a thermal protection mode. If the chip gets too hot, it will turn itself off. Most of the time, this protects the chip against over-current. However, it is still possible to fry (...) (26 years ago, 25-Oct-99, to lugnet.robotics.handyboard)
