Full shot of the cabinet. The bulbs in the very lower right are just three 40 watt service bulbs wired in series from the first refrigerator in our home, (the middle frosted one is an original from the fridge).
Do you also have an interest in vacuum tubes?
I do undervolt the incandescent bulbs, though the actual antiques, (of which I have spares), are wired to go up to full voltage from my control box, but it's still all DC. The gas discharge, or "neon" bulbs are at plain full AC voltage though.
Well, TBH, a limited interest. I've seen them, and I know they can make a great Class A audio amplifier, but I don't have any experience with them. We actually have an old mono amp that my dad used to fix when he was young, but it no longer functions and though all the tubes seem to light, no attempt has been made to fix it. I know vacuum tube based Tesla coils are pretty neat, though I'd probably try a solid state PLL or self-oscillating coil before I did that, though either seems out of reach. Luna alone was a big task, and I may not even be able to make up that time spent, let alone try something new for myself.
Sorry for the discourse there, just something that's currently on my mind. :/
Tube collecting can get expensive very quickly, so I don't do that.
Learning about tube history is fascinating for me and it started with adding one more component to a light bulb which resulted in the first diode (Fleming valve). Add another component and you have the first amplifier (Audion).
After that, it got crazy.
Videos on all kinds of tubes and tube theory are in abundance on youTUBE.
ps Tesla coils rock.
I believe it.
Sweet! Makes sense though. And it sounds similar for the first transistor, there's probably a million different kinds.
Wow, talk about audiophile style production. ^^ Glad they're still in production though. What I'd like to see probably no longer exists, and that would be the Mount Vernon Museum of Incandescent Lighting.
I have a few, but one is in pieces for storage. I have a small one I'd actually like to get rid of at some point. Here's some long exposures I got done for class: adamlhumphreys.com/gallery/pho… adamlhumphreys.com/gallery/pho… Uses a 4kv @ 5ma neon transformer as the power supply, classic spark gap style coil.
You get what you pay for...
So many people want to earn money so they can go blow it"
Glad to hear it. These people create jobs and pay extra taxes so I can keep my cash in the bank to finance my retirement
Exactly. I just wish someone who lives at our home weren't one of those people. This extra shed junk to store more junk is nonsense! Even 4 dish sets would be more than enough for any normal person!
I have to say, that video certainly looks interesting. Haven't watched it in full yet, but I'll say there two sides of the coin as far as incandescent light bulbs in particular are concerned. 130V vs. 120V. Our house came with incandescent bulbs rated at 130V, and rarely did they go out in the 7 or so years we used them before switching to CFLs to save money. 120V bulbs on the other hand would burn out much more often. One could say that's planned obsolesce, but in this case there's a tradeoff. They might've burned out more often by being pushed harder since they were meant for a lower voltage, but they also produced more brightness at a slightly higher efficiency in lumens per watt. (And I haven't particularly monitored the voltage from the wall throughout our time living here, but the few times I have, it's about 125V AC.
Another point, while planned obsolesce is nothing new, I'd like to comment on the slight bit I saw on socialism. Certain things may have been made better, but I'd imagine there'd be a lack of incentive to work let alone produce something new since there would be no long term benefit for the person who designed it. At least in capitalism we have a choice of whom we buy from, and if they're stuff is cheap, word will get out to their demise, (so long as there isn't a counter productive government giving bailouts).
But yeah, that's why if you really want something to last, you buy commercial or even industrial grade stuff. It could cost a lot more, but there's a reason for that. I learned that the hard way here:
APC UPSs are cheap too, had one and the relay failed in less than a year or so. And here's an example of lights that are designed to last and over 100 lumens per watt! : www.youtube.com/watch?v=zM3pR6… Though people don't typically drive over light fixtures, it proves a fairly strong point.
The cartel involved every light bulb manufacturer worldwide. Their target was to reduce the lifespan from 2500 hours to 1000 hours, which they did, and consumers had to suck that up.
I've been using APC UPSs for 20 years. I find they work well, if used as intended. Only one of them had a bad design where the battery didn't have sufficient ventilation and died prematurely.
I also don't bother replacing the battery when it dies, I just buy a new UPS.
If I ever need an LED fixture that doubles as a vehicle ramp or baseball bat, and want to pay extra for the structural upgrade, I know where to go.
I am much more interested in the quality of the circuitry (coils, rectifiers, capacitors, are the LEDs undervolted?, etc) and how the warranty is worded.
100 lumens per watt is nothing to write home about.
Cree is developing a 200 lumen/watt LED.
Salesman at Home Depot wants me to spend $30 on a single bulb. I asked about failures. He tells me that cycling them shortens their life.
So, turning off the light when you leave the room shortens it's life, huh? Sign me up !
Funny thing, I am now on my eighth LED flashlight. Why? Because the support circuitry (switch) failed.
I thought they were supposed to last forever.
I found some cheap CFLs that I like, and I'll be sticking with them until LED lighting gets it act together.
No biggie, still looks interesting.
Except for the ones who were frustrated and educated enough to use a dimmer or auto-transformer. ^^
Well, if you only had to use one every two years, I suppose that’s better than my experience, but still way to short for me. (But hopefully you had a slightly better experience.) Since using my simple switcher, I haven’t had any real problems, not to mention using three 8Ah batteries (with 2 available expansion slots) works out really well. I ran the computer one time for about an hour and the inverter didn’t even start squealing. The only one-time drawback I ever experienced was the relay didn’t click during a certain extended brownout. However, the APC UPS would burn up it’s relay just at the transient of turning on my laser printer. Then it happened that I’d turn on my printer, and my computer turned off. That’s a really bad reliability score IMO. If I ever needed to try another all-in-one UPS product, it’d probably be a Tripp Lite.
Dunno man, haven’t been interested. Good questions nonetheless. They might not cover it being run over by a cement truck. I know you can remove the diffuser trays for cleaning though.
I actually have one of those, (16.5 watts), I slapped onto a CPU heatsink with a fan. Obviously the fan takes a bit of current from the constant current driver, but it stays super cool. I stuck it into one of those little wooden Hobby Lobby chests, cut a hole in top and used aluminum foil as a reflector. Of course plexiglass is in front of it and foam cushioning around it so dust can’t get in through the top. That wouldn’t be any good. I’d like to get one of those 100 watt LEDs someday. I have the heat sink for one!
Heheh, yes, the switch is the most cheap part of those flashlights. That’s actually what I used in Luna’s tail for the power switch, but knowing that it’d fail sooner or later, I used a real toggle switch located with the batteries as the fallback. (I think you can buy a new bottom though. I know you can buy replacement battery holders for them.)
Can’t comment on quality, but I’d try them if we needed some. Otherwise, I agree with ya. I remember way back I got some 23 watt dimmable ones for my ceiling fan on eBay for a great price at the time, (about the cost of a non-dimmable one IIRC). Still got a couple spares left, they’ve been working well as far as I’m concerned and don't take forever to light up enough to see well. ^^
