Vcc, Vdd, Vss or Vdd. What are they and wich one is ground and power?
Ive heard it earlier from a electrician and a teacher, but I seem to keep forgetting it. So to start remorizing it I started to write this article. Its actualy pretty easy when you remember why it is called VDD or VCC for power and VSS and VEE for ground.
Because of the Transistors inside the IC your connecting it to. ill qoute: "Apparently this terminology originated in some way from the terminals of each type of transistor, and their common connections in logic circuits (i.e., Vcc is often applied to BJT collectors, Vee to BJT emitters, Vdd to FET drains, and Vss to FET sources). This notation then carries across to integrated circuits" Eric Seale and Wilf Rigter.
Its source: http://encyclobeamia.solarbotics.net/articles/vxx.html
and the table from there:
| BJT | FET | "Vxx" meaning |
| Vcc | Vdd | Positive supply voltage |
| Vee | Vss | Negative supply, ground |
Research and sale
I have been thinking about what to sell and what to keep.
Most inportantly, for what kinds of projects do I have the time next to family, skool and main projects?
I do think I have to much playstations and I think I can sell at least 1 xbox one. Have a lot of controllers and some other stuff arround for sale. So you may see some of them online in my dump store.
The money Ill collect will mainly be used to buy a good soldering station, a logic analyzer and/or benchtop powersupply.
For my skool project for Embeded2 I do have now a LPC board, LCD screen and LiPo accu, so its now about soldering, finding a good 3.3 to 7 volt source and program my watch. As I have seen my classmates selling and buying a lott of nice stuff, I think I can get most of theyre stuff cheaper and sell asswell.
Anyway, you, the reader, is maybe not so intrested in this talk ive done, or you want to hear more about other stuff. actualy, I have no idea who reads this. so a way of communicating here will be made soon after I release the first products in the dumpstore. expect it to be here in the next 7 days.

Well, if you are using 2.1 of vasfmc and cant find the file to put in the FSX /modules folder. Heres a tip:

Ji\ust in case you want to extract just the file, its a INNO setup program, use the inno setup extracter CMD tool to get. Ill update this later for a small tutorial.

Xbox DVT4 and Chihiro projects
Small update on what I do,
Ive been researching some stuff on the Xbox Development systems.
I found multiple versions of a controller chip inside the Xbox and we "the internet" already knew the Chihiro (An Xbox based Sega Arcade system using a GDrom drive as medium) is using a chip of the DVT3 board. Now is it posible to run it on my DVT4? and maybe later on a Retaill xbox?
Also, can we improve or enable the CXBX emulator to run Chihiro games ?
here are some pictures and links. Just to keep my blog a bit fresh :D
Chihiro board as see here ^^
Someone asked a few questions about the chihiro ehttp://www.assemblergames.com/forums/showthread.php?40914-Chihiro-Development-Kit
