i took a minecraft sabatical, and now I'm playing again, mainly because of all the new stuff added with last update. Is it just me, or should the light sensor be called the solar panel instead? When I hear "light sensor" I immediatly think photocell, which makes me think of its most common use as a (normally closed) dusk to dawn sensor used for lighting. It is light out, so the output of the photocell is 0, or open. When it is dark, the output is 1, or closed. either completing a circuit, or, in minecraft, generating redstone output. HOWEVER, it is actually programmed the OTHER way, which just boggles my mind. Whoever developed this sensor, (Jebb, i think), IMO, did it completely backwards! WHY oh WHY would you program the output to be opposite of what most users would use? As is, it requires an inversion to be used as a photocell for turning on lights at night. I long for the day that I can simply stick a light sensor on top of a redstone lamp, and call it a night!
IMO, this little gem would be MUCH more useful with output at night, and off at day. It is much more space saving for lighting circuits, and doesn't matter so much for daylight activation of farming machines.
If only it was named Solar Panel, and maybe we could have a photocell to do the opposite.
any ideas on how to minimally inverse the sensor output?
Its called a light sensor, not a photo transistor. Therefore, it senses light. If you need power at night you invert the signal. If you need it to act like a photo transistor, you can put a comparator in subtraction mode. I don't really think it would make a difference if the signal was inverted.
…any ideas on how to minimally inverse the sensor output?
Daylight sensor next to dust on block with redstone torch under sensor attached to block. Then you can put lamps around the torch or under it to hide it, producing a night-activated street light.
i have the sensor hooked up to redstone lamps in a way so they come on as night approaches and off as the sun rises, simply put a trail of redstone from the sensor (i put it 4 long to get the on-at-night-off-at-day effect) to a block, on the other side of the block, put a redstone torch, so when the sun hits the sensor, it creates the current and sends the redstone out and hits the block and turnes the torch off, when night comes, it doesnt output enough tokeep the redstone torch in an off-state so it turns on and if you put redstone dust on the other side of the torch, it powers it, then simply hook up the lamps, heres some pic's
this is when you use the command "/time set night" which is 12500, the one with 5 dust has lit up but the one with 4 is still creating enough output to keep the redstone torch off
this is about 10 seconds later when the daylight goes down even farther and the one with 4 dust can no longer keep the torch off, it lights its lamp, as the sun comes up in the morning, the sensors will sence more light, create more current, and tunr the lamps off, hope this helps
heres a way to always have them off, put a lever on the side of the block and turn it on so it always powers the torch and turns it off, simply turn it back of to allow the regular cycle to take place
this picture is in the dead of night, the one with 5 dust has the lever in an on-state so it turns the torch off thus keeping it off, even at night, the other has the lever in an off-state so it doesn't affect the cycle at all, it keeps on-at-night-off-at-day where the other is always off, you can then toggle the lever dependingly, hop this is what you meant by day/night toggle on them

No. I meant something like right clicking on the sensor to make it send power when there isnt enough light, just like streetlights have. I think the OP's gripe is that we should be able to place a sensor on top of the redstone lamp to make it turn on when it's dark. Someone should make a mod, and/or plugin..

I did a sticky piston with redstone block. The Light sensor powers the piston during the day keeping the redstone block off the line. Then at night it retracts and activates the circuit.
I used this to create street lamps when the redstone block retracts it powers 4 redstone lamps.

The point is, if he broke the complicated day/night sensor that people used to change the state of a grass block momentarily to switch on and off a light circuit so you could have lamps at night, and then put this block in; then wouldn't it make sense for a light sensor to sense the fact that there is no light then have an output? What do most people use it for to begin with? Night lighting. The choice to use it as nothing more than a solar cell is just plain stupid. Yes, there are daytime applications for it, but IMO, they are far less than that of nighttime uses.

you could put a lever and a dust trail leading to the lever from the lamp and turn the lever on/off to turn the lamp on/off likewise, but i dont think there is any way (without mods) to simply put a sensor on top of the lamp and have it do what the NOT gate (what i show'd with the first 2 pics) will do, for more info on redstone gates, go here http://www.minecraftwiki.net/wiki/Tutorials/Basic_Logic_Gates
Its called a light sensor because guess what, it senses light... duh. A solar panel would be an incredibly horrible name. A solar panel would be used to charge a battery. A light sensor just senses light.
What you want is a dark sensor.
Just use a simple redstone inverter. Don't tell me you don't know how to make an inverter with a block and a redstone torch...

Trust me: I FULLY understand the function of inverters. My previous comment wasn't aimed at your inverter setup. I was griping about the lack of a toggle on a vanilla lightsensor. My point is, its not cool or even feasible to have to set up an inverter on top of a small streetlight. You cant make it look good, unless you make it huge, like Munin's picture above. Nothing against that, buts its awfully bulky for a normal streetlight. And nothing against your design either, but you cant put that on top of a streetlight, and that was the OP's request to begin with. It wasn't that he didnt know how to invert the signal. He wanted to know a way to "minimally inverse the sensor output" on top of a streetlight. Streetlights are not on the ground, like your pics. They are up in the air, on a post, and they are fairly small.
So someone at bukkit made me a plugin to toggle the sensor. Of course, it only works on SMP, but heres a link: http://dev.bukkit.or...ds/nightsensor/ Hopefully someone will make a SSP mod as well. Maybe even a part of Zombes modpack. My whole point is, its kinda ridiculous that they didn't add a toggle while creating the vanilla version.
I explained earlier that you can use this method to make a street lamp, effectively inverting the signal:
My only qualm with this method is that the top of the lamp floats during the day, which can be hidden but it is hard to make that look good.
I have been working on a way to have a piston under ground push the fence posts up and down with the rest of the the lamp but haven't finalized a design.
I dont quite understand what you are saying, but do you mean this?
This is somewhat an inverted circuit, activating the lamps only at night and turning it off in the day.
You can call this a photocell? i think..........
Well, it fits your description and it is inverted.
It changes daylight sensor into night/darkness sensor.
Is this what you wanted?

Use a redstone comparator and a switch.
If it was simply a light sensor, it wouldn't power anything....duh. Now, aside from responding to asinine comments, I will explain why it is a photovoltaic cell. A photovoltaic cell, aka solar cell/panel, actually produces power during times of light, and does not produce any during the absense of light. (http://en.wikipedia.org/wiki/Solar_cell) However, a light sensor, merely senses light and tells a seperate circuit that there is light, but does not actually produce any current whatsoever. (http://en.wikipedia.org/wiki/Photodetector)
Calling it a light sensor would be fine if it produced no power, but it does. It clearly is a solar cell.

thanks for the suggestions! as for the snarky "Im smarter than you" comments, go eff off. I especially like the one from munin295, as this is exactly what i was looking for... a good looking simple street light in vanilla minecraft without the use of plugins. Hence my complaint about the daylight sensr... as most people wanted a simple way to make lights turn on at night. horaholic, you hit the nail on the head with the "you need to make it a toggle" idea!

Thats a pretty good idea there. Its still a little bulky, but I like the concept.

yes, but I was specifically talking about the idea that the sensor should include a day/night toggle as a right click, just like setting the repeater timings. Also, thanks for the quote- Kudo's to Gabriel, I forgot to include your name in my last post.

Its not powering anything. It is outputting either a 1 or 0 (or variations of those), IE sensing if light is present.

Ok then explain how a switch powers something... You will discover that nothing in minecraft really "powers" anything, everything is merely a command or sensor.
