Sagebrush posted:video signals into yr eyes wouldn't do it either unless the video machine has a way of reading the movements of your eyes and perfectly mimicking the natural changes in perspective and focus that would come with those motions. the nasty disconnect with stereoscopic 3d happens because the stereoscopic films only give you one of several cues you need, while all the others are saying 2d. video signals would do the same. holograms create the actual light pattern of the 3d object and let you look at it as if it were really there, so there's no mental dishonesty Honestly it probably has a lot to do with the framerate too. if u have not seen 48fps 3d you really should because it is a world of difference in terms of watchability

i've got two TMP35 temperature sensors fresh out of the bag. +5v on the correct pin, gnd on the correct pin. i know this because it's not on fire. readout on Vout - 0.0 volts. both of them do this  i stuck an LED in place of the sensor with the same alignment and it lit up so it's not the breadboard. tested the analog input pin, it works. idgi

The TMP35 outputs the temp in millivolts. Look at the SparkFun page for the TMP36 (beware that the TMP35 has a different temperature range than the TMP36 shown on the page, so the math shown in the comments won't work as-is since the sensor will output a different voltage for the same temp). Direct link to the TMP35/36/37 datasheet. According to the datasheet, the TMP35 outputs 250mV at 25 degrees C, with an output scale of 10mV per degree C. What's the approximate temp where you're working? Pay attention to the fact that the pinout shown in the datasheet is looking up at the bottom of the device, not looking down at the top. So, with the flat side of the sensor facing you, the left pin is VCC, the middle pin is VOUT, and the rightmost pin is GND. Is that how you have it hooked up? (this is assuming you're using a TMP35 in a TO-92 package) You'll also need to read all 10 bits from the ADC, no cheating and just grabbing the highest 8.

What's the approximate temp where you're working? It's wired correctly (it's not currently on fire). The ambient temperature would be 23-25C. My digital multimeter had a battery leak inside it so all I have is an old Calrad analog multimeter from the 1960s. I'm getting all 10 bits from the ADC, the range is 0-1023. The sensor is hooked up to analog input 0. The readout from ADC0 is 0. I know the ADC works - the buttons on my LCD board are read through that analog input when I have the LCD board plugged in.

adc for button input is ok if you choose your resistors wisely and code around it more of a pita than just getting shift registers imho

Luigi Thirty posted:It gives you the weekly nfl scores maybe. you can check the board really easily by using your multimeter in the diode checking mode. also if youre using alligator clips (or anyone that is) - check them every week or two to make sure they still work. alligator clips are pieces of poo poo and made as cheaply as possible. its completely possible to buy a pack of 20 or w/e and have 20% of them not work.

Today we are building a fence so we no longer have to see our jackass neighbor.  in a couple of weeks I'm having surveyors come out because he's being a dick about property lines, and the current GIS maps state half his shop/etc in his backyard are on my property(including his chlorination system for his pool!). . . so yeah I love this neighborhood, except for that fuckin guy.

(that video is kinda dumb I know) seriously though it's just a fun combinatorial problem to play with (this is the idiot spare time projects thread after all), there's various papers using it to benchmark new techniques in combinatorial optimization. it's very similar to the 8 queens problem but much more elegant to state.
