A brake for the Military Service

The time has come,
to serve do my Military time.
See you all in 9-months!!


A-SIM hits front page @ http://www.x-simulator.de/forum/ :D

Nice day today!
A-SIM hits front page in the X-SIM's homepage.
It's the forum of the software it is used to read values out of any simulator.

Fairly big smile :D


Cursor :)

Just for fun:

It is a mouse cursor. Right click and Save Image As to download it.


DIY Projector. 1024x768, 250W. ~100 Euros.

I just finished building a DIY Projector. I used a 3M 1680 overhead projector, a CTX PV700 17" TFT display, some wood and 6x 6mm 12Vdc fans. The outcome was quite a surprise! Good refresh rate, BIIIIIIIG screen but not as bright I was hoping. Alas, I was very pleased from the performance of a ~100 Euros projector!!

Hotas.gr - Greek flight sim site.

I was browsing the web and fell upon this very interesting site. Moreover, i found out i was used as a software reference in their DIY joystick! :)

A-SIM video

Here is a demo-video of how A-SIM works.

Unfortunately i do not have an efficient way of showing the airflow through a camera..


A-SIM: Create airflow to feel the airspeed you fly/drive

I finished building a project i had long time in mind.

It is called A-SIM and it is a serial-interface peripheral which reads airspeed and sideslip values from the game through X-SIM and simulates what the air would feel like in an open cockpit. To create the airflow, it uses computer fans. In my case, it outputs around 4.25 m3/minute (~150 QFM), which is quite a lot. I have used it for IL2 open-cockpit airplanes, but it can be used for racing simulators too.

It is based on the PIC16F887, powered by 12Vdc, drives up to 4 PC fans(!) and its total cost is below 20 EUROS.

With 4 PC fans one could get around 10 m3/min, you would need goggles to face the screen!

ICARUS ONE kit for J.A.K.

On Tuesday i shipped another console to J.A.K. from the Nederlands. Being a true Dutch, J.A.K. requested a Fokker G.I. to be engraved on the console, so i did it. The result was great!

J.A.K. suggested buying only the console box, with all the internal electronic connections done by him, so he bought it as a "DIY-kit". 

The cost was less than the 1/3rd of a finished ICARUS ONE, so he came up with a very economical package.

JYETECH oscilloscope case

I finished designing a case for my oscilloscope. It was bought from JYETECH.COM as a kit, so it did not come with a box.
I created a box from black plexiglas, and housed it in. I added an internal 9v battery (PP3-type) to be able to use it as a mobile instrument. I also fitted a POWER ON/OFF slide-switch and a BACKLIGHT ON/OFF switch to extend the battery life time. Finally, I created the connections for easy RS232 serial interface with a computer, to extract screenshots from the oscilloscope and a plexiglas cover for the fragile LCD screen.

Here are some more pictures:

The total cost of it was around 12 EUROS.
Please contact me if you are interested in one.

See you on Feb 12th..

Miskatonic's team (ie me) will be taking a time off, to concentrate on the exams.
I'll be back!

PC power supply modification. ATX PSU hack with regulated variable voltage and LCD voltmeter.

I needed a PSU (Power Supply Unit) for my electronics projects, so I modified an old ATX PSU (computers' power supply unit). It outputs a total of 400W and has a regulated variable voltage output of 1.25V to ~21.75V (DC).
Click here to see the full slideshow
I used a LM317 voltage regulator, some switches and the original PCB of the PSU. The project turned out to be extremely easy to build, minimum soldering, finished it in 1 day!

The original PSU was  a Τ & P MEIJI, Model: MEIJI 400-ATX (400W) and it now outputs:
  •  +3.3V, 28A
  • +5V, 40A
  • +12V, 18A
  • -5V, 0.3A
  • -12V, 0.8A
  • Vvariable: 1.25V - 10.75V or stand-alone 1.25V - 21.75V
