Camera Slider Track Part 1

I have long wanted to work on some motion-controlled camera rigs, for time lapse and moving video shot purposes.  The longest-brewing idea I have had is for a motion-controlled cable camera rig for setting up some elaborate mountain bike shots, but there are a lot of engineering hurdles for that project and I just haven’t ...

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 ...

Diansu DS-982 Solder Paste Dispenser 4

I did a review, mini-teardown, and test of an imported pneumatic solder paste dispenser that I picked up on eBay.

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 ...

Benchtop Multimeter Repair: ebay Bargain Hunt

I picked up a broken Agilent U3402A Digital Multimeter on ebay for a good price, taking a gamble that I’d be able to fix it.  I put together a video where I tear the meter down, diagnose the problem, and come up with a working hack to fix it, all in “real time.”  It’s a ...

Measuring with Software

Every so often you may need to measure something small and inconvenient.  Specifications with physical dimensions may not be available to you, so you need to actually measure the item you have at your disposal.  For example, if you want to experiment with a harvested electronic component and put it onto your own PCB, you ...

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!
