I bought a couple of months ago a little AVR Dragon card. My initial plan was to use it for debuging programs with the embbeded JTAG. But I run into several issue with that, mainly because the lack of doc on this topic. So, here we are ;)
The AVR Dragon is nice because you can [...]

I recently bought 2 LCD from jckrers ebay store. I have a good idea for this stuff, but first I need to run several tests. This LCD are fine and use the common KS108 controller.
My first thought was to use the avrlib, so I wired the LCD and started to use avrlib, but I quickly [...]

Yesterday, I ran into a issue with an ATMega32. In fact, I wanted to disable the Jtag support on the chips because I need to use the pins used by the Jtag (PC2-PC5). To disable the Jtag, you simply need to change some fuses. I changed the fuses with the help of the Avr Fuse [...]

I’m now building another clock with a IVL1-7/5. In fact, I’m preparing a large bench of VFD clock, and I need to test several stuffs, so the schematic isn’t public right now.
This one use quite the same stuff than my previous I IV-18 clock, the main difference is the VFD power supply, but if you [...]

Here a little video of my clock. In fact, I decided to replace the video on dailymotion ( it offers better quality than youtube)

In the previous article, I have study the way to power this large VFD, now we gonna take a look closer at the logic itself. We need to drive a lot of bits (8+9) at ~40v. After a little googling, I discover that Allegro still sell some VFD drivers, but they are really hard to [...]

Hello HackADay / MakeBlog / HackedGadget users, be sure to read the second post,
as most pictures are here.
/ Enjoy
After my nixie clock, I decided to build a new one based on a old VFD vacuum tube. In fact, the brother of a friend (which live in Ukrainia) give me a bag of tubes. Beside I [...]

Hi all, I haven’t post here since a while right now. In fact, I spend quite all my time w/ playing with some electronics stuff.
Some people asked what I’m doing .. that it .. here a teaser
This is some New Old Stock Russian VFD vaccum tubes.. ready for my next RSS reader !
I’m looking for [...]

While debuging an AVR microcontroller, you need to play with bits. After playing with my calculator I decided to find another way to decode bin/hex etc .. I found a good recipe on ASPN.
Now, this is a little reminder for people (like me) which doesn’t read binary op fluently.
# This will off the bits [...]

Ok, I’ve been off for a while right now. In fact, I’m playing with electronic’s stuff a lot. I just decided to build a nixie clock (for the fun).
For those wondering what is a nixie. Take a look at Wikipedia
And a nixie clock look like this:
There is a couple of hard stuffs to fix for [...]
