It also has an | extra _optional_ power supply (micro usb) which is useful if you | chain a dozen to one pi zero. | | - the usb only ones can be as low as PS5 on ebay ($6.55) and PS10 | for passthrough. | | - it featured in an artcile by Micael Lynch which featured here | on HN, where he explored the latency involved with such video | caprure devices (https://mtlynch.io/tinypilot/) | 1MachineElf wrote: | Very impressive project, and I'm especially grateful for a | detailed example of ps2dev. I was looking at ps2dev last year, | wondering what it would take to create a PS/2 input device. | xuhu wrote: | If you give up the video capture part, a smart plug and a | Raspberry Pi that can send Wake on Lan packets and can act as an | SSH gateway should work, without extra parts. My beige Linux | boxes currently use a $20 8-port switch and a Pi that's reachable | via port forwarding. | folmar wrote: | Then you can also live without the raspberry pi.

A lot of servers only have vga | available. | mtlynch wrote: | TinyPilot author here. | | You can capture VGA using all the same tools by adding in a | VGA to HDMI adaptor. I haven't measured the impact on | latency, but a few users have confirmed that it works.[0] | | [0] https://github.com/mtlynch/tinypilot/issues/76#issuecomme | nt-... | blensor wrote: | If you are already using and arduino, couldn't you the use it as | a HID device and send the keyboard (not sure if it does mouse as | well) directly without going through a PS/2 emulation? | flotwig wrote: | Looks like it's not supported on the Nano, Trinket, or Uno, | which were the only devices I had laying around: | https://arduino.stackexchange.com/a/39638 | | Otherwise, that would work fine, but not all motherboards | support power-on via USB HID, most support PS/2 though. | [deleted] | woliveirajr wrote: | > IBM was using the PS/2 standard (not to be confused with the | PS2) to connect mice and keyboards to PCs | | Oh my. I would never expect someone taking PS/2 for PS2. It made | me wonder that many communication problems that I have with some | of my team is caused because I'm a bit dated... ___________________________________________________________________ (page generated 2020-08-22 23:01 UTC)
