by on Jan.24, 2014, under 3d printing

I love my 3Doodler. It is a tool I can not live without. So today when it started to jam and not pull in filament properly I took it apart to see what was going on.
Yup it was jammed with ABS dust.
Then I noticed the fan…

prusa i2 print issue

by on Jan.07, 2014, under 3d printing, Reprap Prusa

So I am trying to debug my prusa i2 after having been rebuilt with a ton of new parts. I keep getting these messed up prints where the vertical shells don’t bond or have a gap between them along with a gap between the vertical shells and the infill.

Energy Efficient CFL fire Hazard?

by on Sep.14, 2013, under Electronics

I noticed something wasn’t right with this light when it failed so I opened it up.
Electronics totally burned up
Inside plastic is burned.
The irony is the burn almost went though the UL label
inside plastic is covered with burn marks
The CFL it self is melted! This had to get quite hot to do that!
The other side of the electronics.

Decapsulated chips

by on May.09, 2013, under Electronics

Warning! Nitric Acid is nasty stuff to play around with. I did this so you don’t have to! Do not attempt to do this yourself or you may end up dead!
So today I wanted to try and decapsulate some chips to see how they were laid out inside.
This was my first attempt. A Leapfrog L1000 arm chip.
Not sure if I etched everything off or this is some sort of copper obfuscation layer.
The other side looks like the standard back of a chip.
Next I attempted one of those custom glued down chips from a older leapfrog toy.
results were much better.
This is one really nice chip to look at :)
Some sort of die marking of who really made the chip. I couldn’t get a clear image of it.
This is at 500x zoom on my microscop
Next up I did a old DEC scsi chip
lastly a simple 8 pin eprom chip
