JustifierS

July 8th, 2011

Do you remember the big box ?
It was full of MegaCD games for my collection and something I was looking for soooooooooo long (at an interesting price) : the Pink Justifier !

So many projects to finish before I use my screwdriver on it 😉
The pink is so hard to find … I know it is possible to “convert” a blue justifier to 2P justifier…I need to find how !
Then I’ll need to find how to convert a Virtua Cop gun…Charles told me it is possible so, I have to try ! 😉

SMD disk drive PSU

July 6th, 2011

Thanks to Charles, I finished my PSU schematic


(greyed area isn’t available in my own disk drive)

I received the tools to fix it so I’ll be back on development soon … perhaps ?

Cart dumper/writer

May 17th, 2011

I’m still waiting for the parts I need so I finally wrote the write part on my dumper….
So I now have a virtually working cart dumper/writer


Yes, it uses a Teensy (only 5 pins! the others one are for debugging purpose only…I won’t use them on final product)

Since I can’t just wait, I jumped back to the Super Magic Drive : I really want to repair it !

Replacement for SMD battery ?

May 8th, 2011

While working on my own flash card, I found interesting chips : Non-Volatile RAM Controllers.
Basically, these chips detects if power drops down and automatically switch to the battery.
As soon as my SMD will be fixed, I’ll try to use one of them to replace the killer battery of the SMD.

LUFA inside

May 3rd, 2011

I’m currently playing with LUFA

LUFA is a framework for AVR…like the one Teensy is based on!
I quickly found developping using Teensyduino wasn’t enought…so I switched to pure C using WinAVR under Eclipse.
I was able to reproduce the Teensy under Proteus ISIS and to test (almost) anything I want virtually…
I already made a (virtual) cart dumper just waiting for the real prototype.
Next goal is my so-wanted USB adapter for the Super Magic Drive.
Then I’ll made a low cost eeprom burner (waiting for the parts!)

The coming month will be very interesting… :)

Sprint Layout

January 16th, 2011

I found a very intersting software : Sprint Layout 5.0
It allows you to use a bitmap as reference to create your PCB layout….front and back sides!
I started yesterday:

I hope it will help me (and perhaps you!) to fix my Super Magic Drive

See you soon for some USB experiments! 😉

Teensy

June 29th, 2010

It’s been some times I’m looking for Arduino.
Unfortunatly, it lacks, from my point of view, 2 important things : a lot of digital IO (I don’t care of PWM, etc…) and easy USB communication (not only to upload sketch)

I recently found a derivated work called Teensy.
It’s exactly what I was looking for!
I really hope I’ll be able to make some electronics soon!
