| CarlFK | mithro: does any coding have to be done before someone starts porting the vga circuts from atlys to tofe ? | 03:57 |
|---|---|---|
| mithro | CarlFK: By porting you mean layout of the schematic? | 03:57 |
| CarlFK | I think so - laying out the traces so a prototype can be fabbed | 03:58 |
| mithro | it would be good to have rohit's code totally working, but I don't think its a total blocker | 03:58 |
| CarlFK | given I have seen 1024x768 vga input send out the hdmi to a monitor, that mostly confirms the hardware works, right? | 04:00 |
| CarlFK | I am suddenly thinking I should try to have a tofi board done in 2 or 3 weeks | 04:03 |

| mithro | RattusRattus: if you have any questions about the VGA boards, feel free to ask - seaLne was the last one to work on the TOFE version | 11:38 |
| RattusRattus | mithro: CarlFK wanted me to have a chat with rohitksingh1 as he wanted me to offer some hardware design support. | 11:42 |
| mithro | Rohit did the VGA board for the Atlys | 11:43 |
| RattusRattus | CarlFK: ^^ | 11:43 |
| mithro | Carl should be asleep | 11:43 |
| RattusRattus | ack but should get that in scroll back later :-) | 11:44 |
| mithro | I'm pretty sure Carl knows everything I just said | 11:47 |
| mithro | or should if he has been paying any attention | 11:47 |
| RattusRattus | boards for the hdmi2usb? (where help is really help another dev who has already | 11:49 |
| RattusRattus | produced boards) | 11:49 |
| RattusRattus | 2016-04-19 20:30 BST < pollo> DLange: nah, it's for 3D of course | 11:49 |

| RattusRattus | 2016-04-19 20:30 BST < CarlFK> RattusRattus: !!! yay!! really. | 11:50 |
| RattusRattus | 2016-04-19 20:31 BST < RattusRattus> tumbleweed: ehhh 1h 2h delta from now? | 11:50 |
| RattusRattus | 2016-04-19 20:31 BST < tumbleweed> yep | 11:50 |
| RattusRattus | I guess there is some confusion somewhere | 11:50 |
| RattusRattus | 2016-04-19 20:31 BST < CarlFK> RattusRattus: can you lurk in freenode #timvideos and jump on this guy when he comes on: (12:29:46 PM) rohitksingh1: hehe true! let me fix some of the [vga] code right now itself :p else I might become lazy again | 11:50 |
| mithro | RattusRattus: the TOFE version of the board needs to be finished | 11:50 |
| mithro | RattusRattus: It currently has an unverified schematic and a board template | 11:51 |
| mithro | RattusRattus: so, someone needs to review the schematic, confirm its good and then route the PCB | 11:52 |
| RattusRattus | well /me can take a look and review the schematics and possible help / do board layout | 11:52 |
| RattusRattus | so I guess that's me then. | 11:52 |
| mithro | RattusRattus: the KiCad files for the TOFE board are in the https://github.com/timvideos/HDMI2USB-TOFE-VGA repo | 11:52 |
| tpb | Title: GitHub - timvideos/HDMI2USB-TOFE-VGA: A VGA capture board for use with TOFE-8x compatible boards like the Numato Opsis. (at github.com) | 11:52 |
| mithro | RattusRattus: The currently working board that Rohit designed is at https://github.com/timvideos/HDMI2USB-vmodvga | 11:53 |
| tpb | Title: GitHub - timvideos/HDMI2USB-vmodvga: VGA capture expansion board for HDMI2USB (or Digilent Atlys prototype board). (at github.com) | 11:53 |
| mithro | (also done in KiCad) | 11:53 |
| mithro | It's a reasonably simple board, but you need to be careful to length match the data bus | 11:54 |
| RattusRattus | ok will take a look | 12:05 |

| *** rohitksingh has joined #timvideos | 14:33 | |
| CarlFK | rohitksingh: can you ... hmm.... I want 720p out of the hdmi. it is reasonable to make that the only vga resolution supported ? | 14:38 |
| rohitksingh | CarlFK: yeah. we can change it to 720p in the meantime. but we would like to have multiple resolution support :p | 14:40 |
| CarlFK | rohitksingh: I hope to bring my Atlys and your vga board to a group of electronics people that might help me fab the tofe | 14:56 |
| CarlFK | so the more you can do by then the better. | 14:57 |
| rohitksingh | CarlFK: awesome! I didn't know that VGA TOFE PCB was ready! :o | 14:57 |
| CarlFK | pfft | 14:57 |
| CarlFK | it is't | 14:57 |
| CarlFK | isn't | 14:57 |
| rohitksingh | then its design atleast is ready? | 14:58 |
| CarlFK | I am not sure what stage it is in. | 14:58 |
| rohitksingh | oh okay | 14:59 |
| CarlFK | I am pretty sure there is no pcb ... traces.. whatever that process is called | 14:59 |
| CarlFK | (06:51:05 AM) mithro: RattusRattus: the KiCad files for the TOFE board are in the https://github.com/timvideos/HDMI2USB-TOFE-VGA repo | 14:59 |

| * RattusRattus is just pulling from repo now | 20:20 | |
| CarlFK | RattusRattus: no no no | 20:20 |
| RattusRattus | ahh ok | 20:20 |
| RattusRattus | well looking at schematics anyway | 20:20 |
| CarlFK | please do | 20:20 |
| CarlFK | I want you to review someone else's work ... assuming they do it in the next few days | 20:21 |
| RattusRattus | ok can do | 20:21 |
| * RattusRattus hasn't used kicad for a while (I'm using Altium in $dayJob) | 20:21 | |
| CarlFK | I offered the local hacker space: trade video work for pcb work | 20:22 |
| CarlFK | and someone took me up on the offer | 20:22 |
| RattusRattus | ok. | 20:22 |
| * RattusRattus recomends #hackvana on OFTC (mitch aka hackvana) to fab your PCBs. | 20:23 | |
| RattusRattus | he brokers a lot of FLOSS/HW stuff | 20:23 |
| CarlFK | RattusRattus: have you heard of https://oshpark.com ? | 20:38 |
| RattusRattus | heard of, never used. | 20:39 |
| CarlFK | friend just got a job there. If I understand ... they just batch small jobs - take everyone's files, tile them onto the size of a large blank, and sub it out to a company that has the machines | 20:39 |
| RattusRattus | yep its a common system (beta/pcb pool, pcb train amungst many others) | 20:40 |
| CarlFK | boards come back, they distribute them back to the customers | 20:40 |
| RattusRattus | most the boards I do are 6+ layers and I need much finer drills than any of the pool players will do (150um mechanical drills, or blind / buried vias) | 20:42 |
| RattusRattus | hackvana have been good for small volue runs for me and several friends. | 20:43 |
| RattusRattus | biggest problem for me is shipping from USA costs way too much | 20:43 |
| RattusRattus | but for you it may well work out good value | 20:43 |
| RattusRattus | ouch 5mil track and gap / 10mil drill sizes for 4 layer boards and 6mil track & gap, 13mil drill for 2 layer boards :-( yep I'm clearly not a traget customer :-) | 20:47 |
| RattusRattus | mind you hackvana doesn't advertise at the levels I have asked for and got either :-) | 20:48 |
