So, which one is better ?
Anything special about Nibbler, except that it can run from regular batteries ? |

I believe the lhf tester is better because of its smaller size and more convenient of using the USB power connector.
Don't forget lhf tester can also test the 4040. The price is also affordable for us.
Sounds like I'm the salesman of lhf tester  |

|

Does anyone know how the 3 x 9v battery connectors are supposed to be wired inside the Obtronix Nibbler? The web site is gone, and so are the assembly instructions.
The Nibbler uses one 7910 and one 7805 linear voltage regulator. |
