| azonenberg | So I did a little bit more reading and it looks like I will be switching my hardmask from Cr to Ni | 20:46 |
|---|---|---|
| azonenberg | I'm also going to be using a more classic evaporation setup in which the sample is mounted above the filament instead of below, so i get more of a line of sight | 20:47 |
| soul-d | evening azonenberg , did you see anything usable for evap on site i gave ? http://www.labstuff.nl/contents/media/1g.jpg < supposed to be one 3" dia but looks like a normal bottle to me :P (also its just 5 eur ) | 21:04 |
| azonenberg | I didnt have a chance to look at it | 21:04 |
| azonenberg | will check it out in a bit, about ot head up to campus | 21:04 |
| soul-d | ok, yeah finishing the day here :) used my new hot air gun from aoyu solderstation to desolder 2x 128mb sdram and some flash as to get to know it | 21:08 |
| soul-d | although i probably would need to assume it was leadfree :) | 21:08 |
| azonenberg | nice | 21:09 |
| azonenberg | i just got my fpga talking to ddr2 sdram yesterday night | 21:09 |
| soul-d | needed 360~ish but worked not to bad for first try | 21:09 |
| azonenberg | now i have to get it playing nice with the 16MB NOR flash chip | 21:09 |
| soul-d | devkit ? | 21:09 |
| azonenberg | Yeah, quite a nice one | 21:09 |
| azonenberg | http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,836&Prod=ATLYS | 21:09 |
| soul-d | yeah ddr2 | 21:09 |
| soul-d | have altera's cheapest set | 21:10 |
| soul-d | de1 and just got the maxII kit and de nano | 21:10 |
| soul-d | and went ahead and orderd a cyclone 1 @ farnell and some randome needed bits | 21:11 |
| soul-d | does look nice though diligent stuff expensive though | 21:11 |
| soul-d | should try seeedstudio out for some simple pcb's | 21:16 |
| azonenberg | This one wasnt exactly cheap but it's very nice | 21:16 |
| soul-d | does have some nice things like eth & usb good qualitty video out | 21:19 |
| azonenberg | Yeah | 21:19 |
| soul-d | my de1 only has vga out with 4bit reistor network :) | 21:20 |
| azonenberg | I tried doing VGA with a CPLD but couldnt get the monitor to recognize it | 21:20 |
| azonenberg | hopefully i can get HDMI working better | 21:20 |
| soul-d | no it was verry picky to screens here to | 21:21 |
| soul-d | vga habbit | 21:21 |
| azonenberg | i see | 21:21 |
| soul-d | a lcd with vga input might be handy | 21:22 |
| soul-d | i think i saw it reporting some data on what it fetched | 21:22 |
| azonenberg | nice | 21:23 |
| soul-d | but if it was crt you tried they can be picky on signal | 21:23 |
| berndj | ooold ones have narrow frequency ranges | 21:23 |
| azonenberg | berndj: I tried a recent Asus 24" 1080p LCD | 21:23 |
| azonenberg | fed it what should have been 640x480x60 VGA | 21:23 |
| azonenberg | timing looked fine on my scope | 21:23 |
| berndj | actually, aren't (some) lcd's even pickier? | 21:24 |
| berndj | electronics can't really tell the difference between 640 and 1920 or whatever pixels; only the line count and frame rate matter | 21:25 |
| berndj | was 480x60 perhaps just too slow? | 21:25 |
| azonenberg | i dont think so, it displayed the same spec signal fine from my laptop | 21:25 |
| azonenberg | w/e... i dont like analog | 21:25 |
| azonenberg | TMDS ftw | 21:25 |
| berndj | a crt might tell you more about what's wrong though! | 21:26 |
| azonenberg | I agree | 21:26 |
| soul-d | anyhow i was quite certain that with osd you could get some data on what it screen thinks it's getting | 21:26 |
| berndj | you'd have some clue about what it isn't happy about | 21:26 |
| azonenberg | My monitor was so confused the OSD froze | 21:26 |
| soul-d | yeah could have been my crt that told me | 21:26 |
| azonenberg | my LCD* | 21:26 |
| azonenberg | I couldnt find a CRT to test with | 21:26 |
| soul-d | trew it out cause it was to big | 21:27 |
| berndj | soul-d, i've only seen osd tell you what your video mode is when the lcd monitor already recognizes the signal :-/ | 21:27 |
| azonenberg | in my case it displayed a black screen with no OSD | 21:27 |
| azonenberg | i tried two screens | 21:27 |
| azonenberg | the Asus froze | 21:27 |
| azonenberg | the other one (forget the vendor) displayed a blank black screen | 21:28 |
| azonenberg | with slight changes to time they both went "no signal" and shut down | 21:28 |
| soul-d | true my iyama still had bnc's on the back | 21:28 |
| soul-d | so maybe it was just biut more special :P | 21:28 |
| berndj | how do you know your laptop outputs 480x60 and not, say, 480x135 (which would be the same line rate as 1080x60) | 21:29 |
| azonenberg | berndj: Because the nvidia x server settings said 60 hz | 21:29 |
| azonenberg | i didnt actually run timing on it but i doubt it would lie to me | 21:29 |
| berndj | ah ok | 21:29 |
| azonenberg | On that note... any tips on how to MITM a VGA signal from laptop to LCD? | 21:29 |
| azonenberg | i want to get probes in there somehow | 21:29 |
| berndj | you did give it blanked lines? | 21:30 |
| azonenberg | berndj: Yes, i used the timing from my xorg.conf and converted into 20 MHz clock cycles | 21:30 |
| berndj | ok cool | 21:30 |
| azonenberg | (20 Mhz = two 640x480x60 pixels) | 21:30 |
| azonenberg | or maybe it was 800x600 | 21:30 |
| azonenberg | in any case the nominal pixel clock was 40 MHz | 21:30 |
| azonenberg | i was running at 20 so i had a min addressible size of 1x2 pixels | 21:30 |
| azonenberg | But that should be fine | 21:31 |
| azonenberg | sync pulse lengths and such measured by my scope all looked OK | 21:31 |
| soul-d | 20mhz for vga ? | 21:31 |
| berndj | i know there's some semi-undocumented trickery involved concerning whether to blank the lines during the interframe period, or whether to invert the sync pulses during it, etc | 21:31 |
| soul-d | i think thats off im sure on 640 it has some weird one like 25.175 | 21:32 |
| soul-d | http://www.epanorama.net/documents/pc/vga_timing.html | 21:32 |
| azonenberg | soul-d: It's 40 | 21:37 |
| soul-d | maybe should try again on lcd now | 21:37 |
| azonenberg | But i halved all of the delays and halved the clock period | 21:37 |
| soul-d | yeah i saw in table | 21:37 |
| azonenberg | They were all even so it should hav eworked | 21:37 |
| azonenberg | and um, now i have an FPGA | 21:37 |
| azonenberg | with onboard PLLs | 21:37 |
| azonenberg | i can clock it at 40 or faster | 21:37 |
| azonenberg | But why bother with VGA when i can do HDMI? | 21:38 |
| azonenberg | I just need to buy myself an HDMI cable lol | 21:38 |
| soul-d | yeah i was dumb enough to buy a weird screen with the dev board | 21:38 |
| azonenberg | Right now one of my monitors is using VGA and the other DVI | 21:38 |
| azonenberg | So both have HDMI in that's unused | 21:38 |
| soul-d | do have 14" ready | 21:38 |
| azonenberg | mine are 24" | 21:38 |
| soul-d | only need to make a lvds | 21:38 |
| soul-d | and it's power supply | 21:38 |
| azonenberg | Oh, talking straight to a bare LCD? | 21:38 |
| azonenberg | I have an expansion port with 20 LVDS pairs on it | 21:39 |
| azonenberg | should try that | 21:39 |
| soul-d | still have a laptop panel around | 21:39 |
| azonenberg | I have a few of those but no specs | 21:39 |
| soul-d | only need to figure out if im right that inrush current is fixed by a big fat cap? egg devices avrage is 350 mA max 550mA and inrush is 2A max ofcourse i want to fix it with a 800mA supply | 21:41 |
| soul-d | yeah glad mine was easy to find | 21:42 |
