[Hackrf-dev] Two Dead Hacks

[James Brown]

I managed to kill both my Hacks. Neither one will enumerate on the USB. Tried several machines. No Luck.
Is there a service for repair of these machines?

Have you tried a DFU mode boot?

Just out of curiosity (and a desire not to step into something) do you
know *how
*you killed the HackRFs? I've seen people who killed the input or output RF
amps because they weren't thinking about RF stages, and I've seen a couple
of reports of people killing them by using poorly regulated battery based
power supplies.

It was one of those “something’s not working on my Hack. I’ll try my second one” things.

I admit I was doing weirdness on the poor boards. I was trying out running USB over CAT 5 and had a USB transmitter and receiver setup with about 150 feet of CAT 5 between. The receiver, the unit near to the remote Hack was powered from a 5 V linear regulator (LM117 with pot and caps etc). Had the thing working pretty well with a bandwidth of 4 Mhz when disaster occurred.

I found that the CAT 5 receiver was also blown so I did something way wrong.

Some fun.

Maybe you had a ground loop problem?

That's a distinct possibility (and a costly one).
