AZIZ! Light! 24

In an earlier post back at the beginning of this month, I described the beginnings of my DIY microscope illuminator project, dubbed Project AZIZ.  At that point I had just sent the PCB off to OSHPark for fabrication.  I’m happy to report that in the weeks since, I not only received the boards back, but ...

More Microscope Hacking: Camera Output!

Apparently hacking around with my microscope has turned into something of an obsession.  The other day, I wondered if I could easily add a camera output to my microscope.  I had a tiny composite video security camera lying around in my parts bin, and somewhat by accident also had a collection of C-mount lenses that ...

Project Aziz 3

My recent acquisition of a stereo microscope for the electronics lab has brought about a couple of side-projects.  One of them is the custom boom stand that I built a couple of weeks ago.  Another is this custom LED ring light, which I’ve dubbed Project Aziz (named after the poor kid holding the mirror from ...

Epic Builds: Articulated Stereo Microscope Arm 2

I’ve wanted a stereo microscope in my home lab for ages.  In the last couple of years, it’s become an increasingly urgent need as I’ve hit the age where my eyesight is beginning to change.  Soldering and inspecting fine-pitch SMD work is becoming difficult without the aid of magnification.  So, I finally picked up a ...

Embedded Hacking Weekend 2

I’ve gotten back into the ARM Cortex M3 embedded stuff (yes, again), specifically with the NXP LPC1768 chip.   I’ve had this Blue Board development board hanging around for a couple of years, and I’ve made a couple of attempts at getting some of the open source toolchains (e.g. CodeSourcery Lite) working with the Eclipse IDE ...

In-Depth CNC Conversion Electronics Overview 2

I converted my milling machine over to CNC back in late 2009.  For most of the time since then, I’ve avoided the project of properly finishing up the electronics that run the machine.  Last winter, I gutted the electronics of the machine, redesigned the system, created a number of circuit boards, and set about revamping. ...

CNC Electronics Enclosure Work Commences… 1

Santa’s workshop was busy today.  I finally got some motivation and time to continue work that I started a year ago, but really, has been a nagging task since day one of getting the CNC up and running.  I have the machine up and running enough to make parts, with all of the controlling electronics ...

Back from Summer Break: Droid Razr Maxx Car Dock

Summer is long over here in New England, and with snow falling from the sky, naturally my thoughts return back to the machine shop, the electronics lab, and the pile of projects waiting to be completed. About two years ago, I designed a universal dashboard mounting system for my car.  The basic idea is that ...

Magnetic Rotary Encoder Video

I found a little bit of time today to make a video showing the assembly and first test of the magnetic encoder board that I designed.  Check it out!

Magnetic Rotary Encoder PCBs!

Sparkly purple packages in the mail always bring good things from Laen inside.  These are the magnetic encoder eval boards that I designed about a month ago.  As usual, the quality is great.  Unfortunately the timing is not ideal, since it’s crunch time at work, and I probably won’ t have time to build these ...
