The sudocade portal is a work in progress combined arcade machine and hackerspace to hackerspace video portal. Currently [[User:Juul|juul]] is working on this project.

= Plan and purpose =

Here are some of the reasons for building this project:

* Promote inter-hackerspace communication and collaboration
* Use multiplayer games as ice-breakers leading in to video chat
* Raise money for hackerspaces by charging money for playing proprietary games (open source are free)

= Bill of materials =

The following materials have been procured:

* One [http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01989776&cc=us&dlc=en&lc=en HP Pavillion dv4 laptop] with a broken screen
:Found by [[User:Tunabananas|tunabananas]] in a dumpster while dumpster diving for food :)
* Power supply from
* Two sets of arcade buttons and joysticks
:Donated by lilia
* One empty home-made arcade machine case
:Via Craigslist free. Retrieved by [[User:Factotum|factotum]] and [[User:Juul|juul]].
* One 26 inch dell lcd monitor
:Via Craigslist free. Retrieved by [[User:Juul|juul]].
* One [http://www.logitech.com/en-us/product/hd-pro-webcam-c920 logiteh HD Pro C920 webcam]
:This was actually purchased since we wanted a high quality camera. Money donated by sudo room members [[User:Notconfusing|notconfusing]], [[User:Matt|matt]] and [[User:Mk30|mk30]].

The following materials are still needed:

* A SATA harddrive.

= Status =

The laptop needs a sata harddrive. Desktop harddrive is ok. Then we need to install the screen

= Notes =

== HP laptop smart pin problems ==

We didn't have an official HP power supply so we had to open the laptop and
solder another power supply directly into the laptop.

Unfortunately the HP laptops have a "smart pin" in the connector.

A resistor between the smart pin and ~19 volt line on the laptop tells the
laptop how much power the supply is capable of supplying.

Internet sources indicate that a 430 k resistor on there should make it work.
Other sources report that a 1k resistor is enough.
One source measured the resistance on a 65 watt and 90 watt official supply.
And found 285 k on the 65 watt supply and 360 k on the 90 watt supply.

I ([[User:Juul|Juul]] ([[User talk:Juul|talk]])) took apart a HP Pavillion laptop dv4 and found five wires:

* Two black: Both ground
* One red: DC plus
* White: Smart pin
* Yellow power for LED (not needed)

I had a 330 k resistor lying around, and connecting it between the red and white wires allowed me to turn on the laptop. I don't yet know if it's causing the laptop to think that a 65 watt supply is connected. If so, it may prevent the CPU from operating at full speed.
