00:04 katsmeow-afk this is too small, but if i could make drive signals to change the color all over of this screen http://www.ebay.com/itm/7-7-Inch-Tablet-PC-Screen-LCD-Display-Panel-For-RCA-Model-RCT6378W2-Repair-Part-/321425590877 can i cut the edges off it to make a smaller square display?
00:51 rue_house well, the panel has fitlers
00:51 rue_house so you will get red light thru, in some places
00:52 rue_house some of the power supplies just dont want to work if the backlight circuit isn't working
00:52 rue_house cant cut the panel, the controller chips are glued to the edges
00:53 katsmeow-afk color filters?
00:54 katsmeow-afk i knw they have polarization filters
00:54 rue_house there is a rgb mask
00:54 rue_house each 1/3 pixel has a colour mask
00:54 rue_house I dont know if the mask is a film in the sandwhich or if its betweent he glass
00:55 katsmeow-afk the chips are on two sides, only, right? top and left, for instance?
00:55 rue_house your document suiggested I put a 10nF+10k resistor from the error amps output to the - input, I'll try that for the power uspply regulator at some point
00:56 rue_house I think the link was from you
00:56 katsmeow-afk so if i cut the top-left corner , it will still have intact chips, and show something?
00:56 rue_house not really
00:56 katsmeow-afk erg
00:56 rue_house I dont think
00:56 rue_house besides, if the glass starts to seperate it all goes to hell
00:57 katsmeow-afk i spose if i grab any old lcd screen from the wild, i will have nochance of guessing how to make it do anything?
00:57 rue_house why do you want a small screen?
00:57 katsmeow-afk to make a rgb flat panel light
00:57 rue_house erm
00:57 katsmeow-afk yeas, there's a trick involved
00:57 rue_house may I simplify your plan?
00:58 katsmeow-afk i'll show pics and make a webpage if it works
00:58 katsmeow-afk yeas
00:58 katsmeow-afk no, cannot use rgb leds
00:58 rue_house why not?
00:58 katsmeow-afk i need to use the light coming in from behind, the lcd is an overlay
00:59 rue_house how com kat?
00:59 katsmeow-afk there's already a pattern, if the lcd is told to show all white, the image in back should shine thru
01:00 katsmeow-afk if the image from the backlite is actually white, i can colorize it by telling the lcd to sow blue, or yellow, or green or etc
01:00 rue_house oh, you want an overlay mask
01:00 rue_house or a programmale filter
01:00 katsmeow-afk if the image is red, i can blank it out by not selecting red in thelcd
01:00 katsmeow-afk yeas
01:01 rue_house why not use an already small panel or a full size lcd?
01:01 katsmeow-afk because the image source is already set up, i cannot change it
01:02 rue_house is there not an lcd the right size to convert?
01:02 katsmeow-afk ~5inch x ~4.5 inch
01:02 rue_house I'm sure there is a colour lcd out there that can be arduino controled that size
01:03 katsmeow-afk i just looked thru ebay's 1000's of listings, didn't see one
01:03 rue_house skadjfhklasjfhdsa!?!?! a 50W blue led is less than $4!!!!!!
01:04 rue_house whats the square root of 45.25
01:04 katsmeow-afk 6.7268120235368551585815427310852
01:04 katsmeow-afk roughly
01:04 katsmeow-afk no listing for skadjfhklasjfhdsa
01:05 rue_house http://www.ebay.ca/itm/4-3-5-7-TFT-LCD-Display-Module-Touch-Panel-PCB-adapter-SD-for-Arduino-/371166552587?pt=LH_DefaultDomain_0&var=&hash=item566b40220b
01:05 katsmeow-afk damn,, blind the poor fish
01:06 rue_house prices just go up from that tho
01:07 rue_house can a person get a 7" digital photo frame for less than $70?
01:07 katsmeow-afk that page is playing real loose with the numbers
01:08 katsmeow-afk active area : 154mm x 85mm , that's not ~5inch x ~4.5 inch
01:09 rue_house its a touchscreen
01:09 rue_house make sure your not mixing up the numbers
01:10 katsmeow-afk i read the gif of the dimensions, 85mm ~= 3.25 inches , not 5 and not 4.5
01:10 rue_house page thru "arduino tft"
01:10 katsmeow-afk that's the problem, the rectangular size, i am looking for squareish
01:11 katsmeow-afk Tom just got stormed
01:11 katsmeow-afk 5 results for "arduino tft"
01:12 katsmeow-afk 2 displays both tiny
01:14 rue_house it looks like digital photo frames were a flop
01:15 rue_house thats halarious
01:15 rue_house its cheaper and better to buy an android tablet and just hang that
01:17 katsmeow-afk arduino tft -"2.4" -"2.3" -"2.2" -"3.2" -"4.3" -"2.0" -"1.44" -"1.8" -"2.8" -"2.1" -touch
01:17 katsmeow-afk no square lcd, the 5" listed are all 5" diagonal
01:18 rue_house ok
01:18 rue_house it was a thought
01:18 katsmeow-afk which is why i thougtof gettig a 7" (diagonal" and cutting it down to 5" wide
01:22 rue_house oh, of course, a person who wanted a digital picture frame could take a raspberry pi and glue it to the back of a monitor
01:22 katsmeow-afk even the tv listed as ntsc (squarish) are actually ATSC wide
01:22 rue_house sorry, I'm distracted
01:24 katsmeow-afk hmm, SHTF is an actual abbreviation in use
01:28 rue_house not STFU ?
01:29 katsmeow-afk Shit Hits The Fan
01:29 katsmeow-afk fertilizer distribution
01:31 katsmeow-afk Spring happens, farmer turns cows out onto fresh green grass, cows make really wet cow pies, mow field with bush hog, cow pies go everywhere, layer onto everything, all is green
01:48 katsmeow-afk i found some 1 3/8 ID steel tube today, but it's almost 1/2 wall, best if turned waaaaaaaaaay down to 1/4 wall, i suspect, which will prolly cost me
01:48 katsmeow-afk it's also not fitting the collet drawbar by .008

02:28 katsmeow-afk ?
02:30 katsmeow-afk http://images.intellicast.com/WxImages/Radar/usa.gif
08:21 katsmeow-afk .
08:22 Remenyhal1 jé, itt vannak emberek
08:23 Remenyhal1 aztán mégse
08:48 katsmeow-afk oh
09:10 rue_house pretty sure the kindle uses a different type of screen, its not lcd
09:11 rue_house maybe I have my devices mixed up
09:11 katsmeow-afk o
09:13 rue_house 'digitial paper' is different, its high resolution, black and white, and takes no power to hold its image
09:14 tsmeow-afk tosses yet anotehr good idea out the wi
09:14 tsmeow-afk goes over to open the window, and toss the good idea a
09:15 e_house leans out the window to check out the
09:15 tsmeow-afk closes the window to keep the smoke
09:15 e_house has the sudden oncomming of a head
09:15 tsmeow-afk opens the window to extricate rue fro
09:16 tsmeow-afk sits rue on the floor and says something about good ideas, and closes the window a
09:17 e_house just thinks of all the things he could do with the good ideas he
09:20 rue_house http://www.ebay.ca/itm/1G-8G-CX-929-Amlogic-S805-Quad-Core-1-5GHz-TV-Stick-MINI-PC-1080P-Android-4-4-2-/261831554661?pt=LH_DefaultDomain_0&hash=item3cf6607665
09:20 rue_house its a computter stick for a tv!?!!
09:20 tsmeow-afk hands rue a bucketfull of ideas that humans won't a
09:23 katsmeow-afk so the tv stick has no mouse controls?
09:23 rue_house 2 usb ports, and bluetooth
09:23 rue_house I think there are bluetooth mice
09:23 katsmeow-afk for keybd?
09:23 rue_house I think there are bluetooth keybards
09:23 rue_house if not, in both cases there are usb ones :)
09:24 katsmeow-afk strangely, i cannot use that tv computer, because my tv is a computer monitor
09:25 katsmeow-afk vga
09:25 rue_house arg, i'm tired, and I have to do a lot of driving today
09:25 rue_house heh, I think you could get a converter
09:25 rue_house I saw an hdmi to vga resampler yesterday
09:25 katsmeow-afk sit on the mowerbot, and tell it where to take you?
09:28 rue_house hmm, it would be a good reason to fix the 72" tv I got
09:29 katsmeow-afk 72" tv? you watch it from the other side of the property?
09:32 katsmeow-afk on the one paw, a 4x8 sheet of 1/4 steel is pricey, but you can have it if you'll just get it off my paw!!!
09:33 katsmeow-afk not much else will do what a 4x8 steel of 1/4 steel plate will do
09:37 tsmeow-afk ponders a tuna-pepper-relish on oatbread sam
09:38 katsmeow-afk at $200 per sheet, it sounds pricey
09:38 katsmeow-afk $6.25 per sq ft
09:40 katsmeow-afk for a 1000 sq ft apartment floor, that is practically impossible for the average person to damage over several generations, $6,250 doesn't sound all that bad
09:40 katsmeow-afk ~32ft x 32ft
09:40 katsmeow-afk weighs 5 tons
09:54 katsmeow-afk looks like the bad storms will form in Missouri and miss Tom
14:11 Tom_itx looks like it
14:11 Tom_itx it's a cloudy cool day here
14:11 Tom_itx if it stays that way, we're good
14:12 Tom_itx if it gets hot and muggy again we'll get bad weather for sure
15:47 tsmeow-afk just remembered she has 100's of 330uf 200v caps for
15:48 katsmeow-afk if only i had 100's of 330uf 63v caps for free too
15:59 katsmeow-afk ok, approximately, including diode, esr, and etc losses, 19v x3 = 48v x3 = 140v x3 = 400v
16:00 katsmeow-afk each "x3" involves 4 transistors/mosfets and 4 caps
16:03 katsmeow-afk each multiplier switcher is operating interleaved 2-phase
16:03 katsmeow-afk all x3 switching is synchronous
16:04 katsmeow-afk throw in a variable 12.6vac/vdc @ 4amps
16:05 katsmeow-afk volt-amp meters on both supplies
16:05 katsmeow-afk make it for $60
16:05 katsmeow-afk what can i sell it for on ebay?
16:06 katsmeow-afk oh, all volts are isolated and floating off gnd, so they can be + or - supplies
16:16 katsmeow-afk been 20 minutes, i wonder if the battery is charged
18:08 katsmeow-afk welp, i dideded it
18:09 katsmeow-afk picked up the 1280 lbs deck, clear off the ground, moved it upright on edge to the other side of the driveway, and set it down and it was within 1/2 inch of being perfectly level just where it lay
18:11 katsmeow-afk not bad for a 500 lb homemade bridge crane, with less than 8ft under it, to lift an 8x16 ft off the ground to flip it over, and move it 8ft before setting it down again
18:15 tsmeow-afk goes out to take pics and sit on the deck and
19:42 katsmeow-afk whew
19:44 katsmeow-afk 1 & 3/8 = 1.375 , but the drawbar tube is 1.380 , soooooooooo it doesn't fit the tube
19:47 m_L gives katsmeow-afk a
19:55 tsmeow-afk looks at it caref
19:57 katsmeow-afk hold the tube in some bearings at each end, spin it rather fast, and sweep sandpaper to and fro over it?
19:59 Tom_L i've done that but .005 might take a while
19:59 Tom_L and more if you want clearance
19:59 katsmeow-afk it's actually .08, the tube is a few thou small
19:59 katsmeow-afk er, .008
19:59 katsmeow-afk after .008 i can work on clearance
20:00 tsmeow-afk sighs at the pain of maybe needing to pay someone with a lathe to take the tube
20:11 katsmeow-afk i don't mean to sound cheap, but i was really hoping to get $600 worth of plate steel delivered this month, and i already have a freaking $100 in that drawbar
20:12 katsmeow-afk and the car could use some $80 tires, and the truck has needed a set of 4 on the rear ever since i bought it
20:13 katsmeow-afk 198.92 x 3 = 596.76
20:39 katsmeow-afk http://www.robotbooks.com/hobby-robots.htm
20:39 Tom_itx is the drawbar for your lathe project?
20:39 katsmeow-afk mill
20:40 katsmeow-afk i will likely reduce the C5 mill to mostly heavy stuff (surfacing), and mere drilling
20:41 katsmeow-afk the ER25 will likely be a fine machine, and much cheaper, meaning i can portable it to the lathe where it can mill stuff the lathe indexes,, or cut spirals, etc
20:42 katsmeow-afk complex cnc the ER25, give the C5 enough smarts to move the bit up and down and the table in one direction
20:45 katsmeow-afk i might say that if i knew then about the ER25, i would not have touched C5 stuff, except the C5 assortment came with a large drill bit chuck and adaptor to chuck in a large C5 collet, too big for a small ER25 machine
20:46 katsmeow-afk and seeing as how i keep needing to drill holes over 1/2 inch, and turn large reamers, i do need an adequate machine to do those things,, that antique big drill press just isn't up to it, as i discovered with the bent spindle
20:48 katsmeow-afk https://stevegrand.wordpress.com/106-2/introduction-to-growing-up-with-lucy/
20:48 Tom_itx my chinese one needs a working thru
20:48 katsmeow-afk the one yo cnc'd? i thought that one was working perfectly
20:48 Tom_itx no the drill press
20:48 katsmeow-afk ah
20:49 Tom_itx the cnc mill is apart now
20:49 Tom_itx still working on the control a bit
20:49 Tom_itx and not alot of time to do it
20:49 katsmeow-afk well, you have the lathe to fix the drill press
20:51 tsmeow-afk grabs the camera and begins the process of making a webpage of how to diy build a pontoon boat from steel that will safely carry 10,000
20:57 Tom_itx tornado sirens going off
20:57 Tom_itx i'm pretty sure it's west of me though
20:58 katsmeow-afk they are, and they look bad, you should monitor
20:58 Tom_itx pretty used to it
20:59 katsmeow-afk ok
21:00 katsmeow-afk wrong camera
21:00 katsmeow-afk not sure if it's FF or exploder i just locked up
21:01 katsmeow-afk thee we go, it was exploder
21:04 katsmeow-afk the bird,, or offspring, is back in the same spot in the barn/garage as the last few yrs, building a new nest
21:04 katsmeow-afk i was sorta wanting to enclose that end of the building
21:06 katsmeow-afk i wonder if the snake i got pics of can get to the nest
21:06 katsmeow-afk damnit, wrong camera agin
21:21 katsmeow-afk well, i dunno where the pics are of the deck upside down, and lifted up on the north side of the barn
21:22 katsmeow-afk i have the pics i took today
21:48 katsmeow-afk well, 500mbytes free on c:
22:12 rue_shop3 "wow, did you laser cut this!" "yes! I laser cut it with my jigsaw!" "...hu?..."
22:17 katsmeow-afk laser line guide != laser cut
22:18 katsmeow-afk now why did my imagemajick quit working?
22:18 katsmeow-afk it's now spitting out nonsense like: mogrify: `%s': %s html2ps -U -o "C:/DOCUME~1/Owner/LOCALS~1/Temp/magick-krvrrhgM
22:20 katsmeow-afk oh, well carp, it was trying to process an html file
22:31 katsmeow-afk http://designerthinking.com/images/PontoonWorkboat/dir.html
22:31 katsmeow-afk you can see by the end of the deck near the door, how much i had to demolition hammer out to approach level
22:32 katsmeow-afk now i need to hammer out nearer to the steel stacked up there, so i can attach the foldouts
22:33 katsmeow-afk i dunno where the pics went of the deck upside down and framed, but those pics i took after i got it standing on edge
22:33 katsmeow-afk then i lifted it, and moved it to the otehr side of the space, and let it down topsideup
22:41 katsmeow-afk hard to believe that's also $800 of plate
22:42 katsmeow-afk i bought before the price went up
23:24 rue_house ee gad your amazing
23:26 rue_house I wonder how much your boat would cost if you did it wood/fiberglass
23:27 rue_house it could come out the same I suppose
23:32 katsmeow-afk but be harder to modify
23:33 katsmeow-afk after walking about on it, i can say that it would be much thicker if made of wood, like solid laminated 2x4s
23:34 katsmeow-afk when the fold-downs are done for launching, there will be 4 6" channel run from side to side, attaching that to wood or fiberglass would be darned near impossible
23:35 katsmeow-afk nothing matches the point contact strength of steel
23:57 rue_house agreed
23:59 rue_house so, should I spend $50 on an android module for the tv
