Re: Camera reduction options...

Well, that was disappointing. Two weekends ago I was in Georgia for a friend's wedding. I charged my batteries the night before, tested the camera when I packed it, and tried using it to photograph a flowering tree the next day...and nothing. No display, and the shutter was locked closed. Turning th...

Re: Nostalgia Lane - Old Time TR Posters

The one thing it would offer me is that a few local businesses and organizations that I actually care about seem to think it is an alternative to having a proper web site and/or mailing list. "Oh, you didn't hear about that? But we posted it on our Facebook page!" Grrrr... :evil: One thin...

Nearly thirteen years here, although I didn't post much in the early days -- was more active on LostCircuits and Ace's Hardware, the former of which is now in archival status and the latter of which is long gone.

Re: Help with distinct wet dog smell?

Check for sewer gas leaks as noted. Failing that, make sure you don't have growths in your HVAC system or the vent pipes for any restroom fans. Could have standing water inside a bathroom vent line if it was installed with a horizontal chase for some reason. I'm going for mold, though, either in the...

Re: UPS battery replacement - Please help (PCM kin-3000ap)

To summarize the problem, the OP is almost certainly talking about a bank of these, generically sold as UB1280 or similar: http://i.imgur.com/VmAgjMo.jpg This is a 12V lead-acid battery, variously rated 7-8Ah, widely used in UPS devices and as backup batteries for alarms and electronic access contro...

Re: dymt reloaded

Interesting. I used to vary between letting a workspace turn into a total mess, then going for a total cleanup, repeat. Lately, though, I've settled more into "organized piles" mode with periodic, gentler cleanups.

Re: UPS battery replacement - Please help (PCM kin-3000ap)

Sounds like you're working with a UB1280 or equivalent Lead-Acid battery? The easy way to check, if the UPS will power up without batteries, is to put a voltmeter across the master terminals from the unit and see if voltage is present. It should be close to 12, 24, or 48V. Note that the unit may be ...

Re: What's the best electric toothbrush?

So I got my tax return, not bad, not bad. I still have some debt to, uh, service, so the majority goes to that.

Re: PC Power supplies for non-PC usage

Ouch -- if you're thinking of paying $114+S&H for a PC supply, what was the manufacturer charging for theirs? Here's another option: take a look at eBay. Specifically, search "12V 8A power supply" and check out the options that pop up. Pay attention to seller location and note that a l...

Re: Old School Retro Light bulbs

I'm guessing those filaments would have the LEDs in parallel. A couple of the aforementioned links suggested a series connection. The junction voltage drop across a blue (or white-converted) LED is around 3V, so it's fairly cheap to string several dies in series to achieve a higher voltage rating f...

Re: What is a balanced/unbalanced converter?

I also have to wonder how much of a difference 3.5mm vs 2 RCA plugs makes, considering the shared grounds. Very little, considering the grounds for an RCA are typically shared at either end. Some higher-end devices will semi-isolate each ground with a ground-lift topology, but if you disassemble a ...

Re: Old School Retro Light bulbs

I wonder if the string reliability is really any worse than any other similar fixture, though.

Re: What is a balanced/unbalanced converter?

Do you really need this device to be an intermediary between those two things? What happens if you don't have it? You can actually feed an unbalanced line signal into a balanced line jack by connecting the unbalanced ground/shield to the balanced ground, and then connecting the unbalanced signal to...

Re: Old School Retro Light bulbs

Well, this is interesting: A closer look at the 'filament' LED (scroll down) Long story short, each "filament" is actually a row of many low-power LED dies, then the whole thing is coated in a silicon diffuser. So I guess the heat dissipation could be pretty good compared to a small number...

Did you try any, and if so, how well did they work? I've been tempted to try something like that for the bathroom vanities, but for $15-20 bulb, I worry whether the LED 'strands' will have a commensurate life span.

Re: Old School Retro Light bulbs

It's been especially hard to find three-way bulbs and bulbs that work well with a dimmer. I still have a pair of those halogen double-bulb thingies in the dining room for this reason. An incandescent, when dimmed, goes to a lower color temperature which gives it "that look". A dimmed LED,...

Re: France plane crash

Latest news is they extracted some audio from the cockpit voice recorder but found only the external frame of the flight data recorder. But a simple autopilot failure seems unlikely, the pilots would have received plenty of warning that their altitude was out of cruising range.
