Re: Streaming frustrations

I know you say you can't get wired to that point, but wireless really sucks. How about doing PowerLine Networking to get wired connectivity over there. Forget the routers with WiFi. If you need good WiFi then go to something like a Unifi Access Point. I have an AP AC LR and it is impressive. I live...

Re: Streaming frustrations

The only issue seems to be the archived files on A&E. We watched a 3 hour program on A&E that was live and it ran fine but just before the archived 1 hour show ran like crap. Everything else plays real well on both the Firestick and Roku streaming stick. Perhaps the problem isn't on your en...

Re: Anyone repair anything today?

Was sitting upstairs doing college stuff for my daughter on Saturday and noticed it was a bit warmer than it should be. Checked the thermostat and it said 82deg -- all the vents blowing warm air. A trip outside found the fan on the upstairs unit not spinning. After a quick check to make sure the fan...

Re: tired of searching for a good budget (under US$200) phone - ideas?

Closest I know of right off hand would be the Moto G4+ or G5+. The lower end models only have 2GB of RAM. The higher have 4GB, but go over your budget a bit.

I assume you are using a circuit something like this. http://i211.photobucket.com/albums/bb259/wpmcnamara/general%20TR%20threads/vjum2.jpg First, make sure you have the resistors in the correct place.

Re: Ideas troubleshooting all-in-one that won't start?

Replace the battery and clear the CMOS (there's likely a jumper somewhere). While no guarantee to fix things, you would be surprised how many times that will address a machine that exhibits very odd boot issues, especially if the machine is a few years old. It's cheap too.

Or pick up a ModMic-4. It will be cheaper than the mic you selected plus the pre-amp/phantom power supply for it, and it will attach to your headset.

Re: How recursive is the real world?

I've used recursion in walking paths across networks for diagnostics. You may have tunnels and you need to know which nodes the path traverses, including all the nodes the tunnels traverse. I've also seen recursion bite badly, it led to a stack smash that caused a 10G line card to reboot while runn...

Re: Optical Media Stream

Yeah, what JBI said. Pins 5 and 6 will provide a voltage that represents the current being pulled. The voltage drop across R2 will be fed to an op amp and amplified before being sampled. Pins 1 and 2 will give a voltage that can be divided down and sampled to get the line voltage. Pins 3 and 4 give ...

P3 Kill-A-Watt meters do have the ability to compensate for power factor. That said, I don't know how accurate that compensation is. Yeah, my thought is that it's not the power factor that's the issue, it's that they are assuming the current waveform is a sine wave like the voltage waveform. In oth...

My guess is that it's a relatively cheap power supply with poor or no power factor correction and the meter is a "cheap" power meter that is interacting very poorly with the power waveform generated by the supply. If the meter simply measured peak voltage during the voltage cycle, peak cur...

I wouldn't trust your meter then. A PowerEdge T110 has 305W rated power supply. I don't think it's possible for that system to burn $50 of power in a month, at the prices you state. I would be surprised if it was over 150W at idle.

The Grados and M50x's should be ok on a mobile phone. My M40x's work just fine on my Moto G4 and they are rated at 35 ohms. The Sennheisers are getting to the point where an amp might help.
