PIC12F629 based AC motor speed controller for mini drills and die grinders. Details of this project is available at jayakody2000lk.blogspot.com/2019/04/replacement-motor-dri...
I made this drawing in less than a hour. It is a design for a
irrigation controller which checks the soil conductivity and opens
waters the plant if the soil is too dry. The parts listed in the
schematic should cost less than $20 and that includes a printed
circuit board. The big expense outside of the actual controller
circuit is the solenoid valve which I do not include in the
schematic. Another $20 there.
Not released yet but a useful option for Steam controller users.

Here's the MIDI controller for my Live performances. My father was building it with my modest help since the September 2006, and it took a lot of sweat and tears, believe me. Yesterday was the birthday of this nice board and I'm more than happy to welcome it to my mobile lab. Dad, you are great!
There's a microprocessor inside and I already implemented a simple MIDI IN / OUT for it, so that it works with Ableton LIVE and other sequencers nicely. The next step is to implement a Mackie protocol to mimic a standard Mackie hardware and be a welcomed control board everywhere without a mundane pre-configuration.
The interface is ready for soldering. All the extra features come in the MAX II board, as peggyback board. See the hole range of MAX II connectors. This CPLD MAX II board is my Standard hardware unit.
The interface board has 71x160mm and is mounted inside the frame. A few extra external flatcables are needed for the external modules like the LCD display, the IR controller into the optical lens and the highpower drive for the external shutter unit. All batteries are also external so they can rapid exchange for loading. The external flashes ( max 3 x SB80/SB800) are all driven into TTL mode so I can adjust the flashpower into the field by turning on one power button on the frame.

Endversion layout, ready to wire on the PCB.
An original Nintendo controller complete with cord.
Everything is completely handmade and edible, from the direction pad to the A and B buttons, as well as the cord.
Chocolate mudcake, layered and covered with chocolate ganache.
Quadrotor Flight Controller class at the HiTech STEM Lab at the East Columbia Branch of the HCLS. The purpose of the class is to introduce students to quadcopters through hand-on learning. The studets investigated the physics behind multirotor liftoff, stabilization, direction of flight, and landing the aircraft. Students worked in teams to assemble the
propulsion system and wire the flight controller and power system. Students honed their flight skills through a flight simulator before flight testing their builds in the final class.

This drawing show the hole hardware interface between the MAX II CPLD controller and all the needed outputs. Components are ordered and will soon be delivered. This should match the mechanical drawings of the hole design. As usual, I make this layout via wiring on hole pcb print raster 2.54mm. A lot of work but the results are very good and reliable.
Most of the function are already programmed and tested into the CPLD board. Ofcourse multiple functions are used into the past so only a few new are to develop.

Endversion, ready to wire on the pcb.
I faced the wires down and made an effort to seal the blank cover of the replacement controller with silicon. Wiring pushes against the motor this way and it is not as neat, but hopefully it's waterproof.
Inspired by kriseattle22's Cabinet For A Gaming Geek, I retrofitted controller storage onto our cabinet.
That's the Heirloom Audio Pier (aka Heirloom Entertainment Pier With Door) from Target. I have added pieces from elfa's Platinum Door & Wall Rack System: the Mounted Standard (37-3/4") with Deep Baskets (17-1/8" x 5-1/4" x 5-1/2" h) attached.

These are the 'regular' PS3 Controllers I have. Two of them are official Sony Six-Axis, Dual-Shock ones while the other one is somewhat of a cheap-knockoff (But still works well!).
So I guess I have a total of..5 controllers? Comes in handy when you have friends / guests round :)

The original PlayStation controller did not have analog sticks. Instead, it had one of the worst D-pads I’ve seen, with each direction being a fake button. Instead of using letters or numbers to indicate the buttons, the PSX gamepad uses Square, Triangle, Circle, and X. It also brought back the “Select” button, which had been missing since the SNES. The PlayStation also decided that having just two shoulder buttons wasn’t enough and had a total of four shoulder buttons.

The original XBox controller was designed by people with hands, unfortunately, those hands were the size of Andre the Giant’s. This thing is big and heavy. Easily frustrated people should avoid using this controller, because it is likely to cause severe damage to anything it hits when thrown.
