Poi operational.
Do you know how difficult it is to apply a logic probe to a circuit that has two modes: blinding blue light and blinding red light?
(WARNING: do not stare at project with one remaining eye)
This is the LiniStepper step motor driver built on a (dual) breadboard.
I wanted to control it using my arduino but couldn't get the board to work. So I ended up building a simpler version using only the TIP122 and a single resistor per input. This is ok because the TIP series has internal flywheel diodes and shut off. Additionally I still use the 5w 1ohm resistors to provide a level of current limiting
(rolling stones - 1965). who knew "the stones" were so far ahead of their time when jagger and richards wrote this song. they had the foresight to see cloud computing 47 years ago! brilliant.
btw, this toshiba ultrabook with the intel atom processor is the lightest notebook ever made.
it's so light, that they actually had to velcro it to the table. otherwise it would've floated away.
Macro of some 'old school' electronics, meaning pre-surface mounted devices and computer chips. Circuit board from an old battery backup emergency light.
Now you have an animal that twists in the middle, and provides analog control to your circuits. Try other animals! Dolls are good, too- you can put pots on the arms, legs and head, if you're clever. Or mix and match!
the camera can't handle the bright display with a dim room but after a day or so, I turned the display red.
My solder joints are looking a lot better now that I have a good soldering iron (Weller 25W) and smaller solder (0.32mm versus 1mm).
Please note that a new hardware version of this device has been released, therefore these images will most likely not apply to it.

The board on the left is an 8 bit LED output port state indicator and also 8 switches to an 8 bit input port. On the right is a 2 line by 20 character LCD display. These can be connected to the Z80 computer to expand its capabilities.

I picked this little guy up at the local Goodwill for $1.99. I was hoping to find a Technics turntable but maybe next time.
Just like every other speaker found in a place like that some jackass came along and poked in the dust cones but of course that's nothing a little bit of electrical tape can't fix.
Four leads coming off of it. The top two are the set and reset. The middle one (sticking out above the transistors and in front of the LED) is ground. The bottom/left one is power.
This is the encoder of a 12v DC motor. This particular encoder has 3 wires, not including the two wires used for the motor. I'd really like to know more about the encoder as these are nice motors!
D'you guys have any idea?
