Bus Pirate Support / Re: Keep getting "Warning: no voltage on Vpullup pin"
Hmm, sorry to bug you again, but could you run through these tests again, thanks.

*connect everything for self test..
*run self test
*now try I2C, leaving all the self test connections on, and not connecting any board/IC to the BS pirate, so try the I2C with selftest connections only..

General discussion / Re: Does aging parts cause Windows to slow down??
In overclocking systems it happens often, since overclocking CPUs and GPUs requires clean power supplies, for stable higher clock speeds. over time the power supplies degrade and clocks become less and less stable.. also if the coolers are not properly maintained they are not as efficient and CPUs now run hotter thus less stable...

But in 99% of cases your gut instinct was right, updates, installs and re-installs slow windows down over time...

Breakout boards / Re: Screw terminals on the ATX breakout board
[quote author="nickjohnson"]Ah, awesome! Does anyone have any feedback on the robustness of the posts when screwed straight into a PCB?

I think it's a bit late to change V1 of the Re:load, since people have already ordered based on info I provided. But for Version 2...[/quote]

ours are screwed straight into the PCB, we've haven't had any complaints on that yet.. Only complaints we've had on the ATX board are why aren't the fuses a gazillion amps :)

General discussion / Re: Undervoltage detector patent application
can someone explain how this circuit even works, cause in my mind it shouldn't.

I get that when the voltage is over the Zenere Level the transistor will holt the SCR gate low, and when the voltage drops the transistor will switch on the SCR... But here is the question, how do you get to that point... If you apply voltage from 0 that SCR will at some point be triggered, and it won't shutoff when the transistor pulls the gate low...

Breakout boards / Re: Screw terminals on the ATX breakout board
[quote author="nickjohnson"]Does anyone know where the screw terminals on the ATX breakout board are sourced from? And if they accommodate Banana plugs? I'm pondering using something like them for V2 of Re:load.[/quote]

they do accommodate bannana plugs, Seeed sources them for us..

Bus Pirate Support / Re: BusPirate 4v2 - Sick of Beige
30ppm is OK, any 12MHZ crystal that will fit on the pads is fine, as long as you also change the load capacitance to fit the new crystal, (probably won't have to do that, but caps are so cheap, so why not)
