Anyone play around with electronics?

I used to build stuff, but not for awhile. I graduated as an electrical engineer, and I built goofy stuff for fun. For example, I built a custom break beam detection alarm system for my father-in-laws shop, complete with my own home made power supply. A year or two ago I helped my son build a couple of guitar pedals, but they were pretty simple. I am rusty as heck with it, as I don't use that knowledge for work anymore.
 
Haven't done much electronics in the last 10-15 years, except maybe wiring up the EFI on the cars.
Everything I have been doing lately is software.
Last interesting electronics project was a complex state machine circuit converting hex commands into coded serial commands with adjustable pulse-width clock timing, and other features.
A few projects I have been thinking about:
I found three multi-segment nixie display tubes I have had for years, and thought about getting a forth to build a clock?
Have a nice digital-to-analog converter that I may use to build an adjustable voltage power supply?
I also have been thinking of doing an Arduino project. Maybe making an electronic degree wheel using a rotary encoder.
 
Went to school for electronics in the USAF. I fixed the RADAR that the Air Traffic Controllers broke. After I got out I eventually got a job as an Electronic Tech for a company that manufactures hobby metal detectors. Never really "played" at home. Recently our TV all of a sudden made a 'POP" and quit working. Took it apart expecting to see a blown capacitor, but can't see anything physically wrong.
 
I would post pictures of a split-charge system I built a few years ago, but my cameras were stolen last week.

Here is a little 'electronic' repair I did last week for a friend...



And this is a box I built up for a roll forming slitter machine last year. Added the Auto-Stop into the roll length ....a feature not previously installed. Took a bit of figuring out with the crazy safety circuits that my fat-bastard ex-colleague had cobbled up....but fixed now. Hooked up via an ABB VSD unit. Customer was absolutely stoked with the operation...as was I ...you can tell the amount of pleasure in the video. :D

 
I started out in electronics and went into programming never a genius at either but have made some cool explosions and destructive failures.
 
I started programming with Arduino. The developer's site has a lot of documentation on the study of programming.This is very exciting.

View attachment 742675 i just put together this little C51 clock kit in about 20 minutes. It costs less than $2 and it gave me a great sense of accomplishment on this rainy Sunday afternoon. I’ve assembled about a half dozen kits from infrared relay controller switch to variable voltage power supply. Anyone else play with electronics? Post them up!

All of your years old pictures were still on the cameras? :( Don't you ever transfer them?

No...that was a 'tongue-in-cheek' poke at another member here who never posts up pictures. :D

Truth is, I have a few DVD/CD' in storage with copies of a lot of my stuff.

Glad to hear of it! :) Of course, you could put almost 100 CDs worth of images on one of these and make it easier to search.

Or, go even bigger. Saves all the time of burning and storing disks.

I bought two of those this week.....16Gb.....one for my Accountant and one for me. These were unreliable and expensive 15 years ago....nowadays....cheaper than a coffee.

heres one for you gurus.
i have boxes full of older hard drives,the kind with the older hookups.
ribbons and plugs.
there are hundreds upon hundreds of pictures on those hard drives.
everything from junk to show cars to family and people ive helped over the years.

does anyone have any idea of a standalone system i could plug these into to retrieve the pics?
most of these were slaved and have no operating system loaded.
 
Here is my latest radio acquisition. A Blaupunkt Sultan 2623. I've always liked this style of European radio, with the piano key pushbuttons, large rectangular dial with country and city call outs, "magic eye" tuning, and wood cabinet.
