Core of this device is 20 x 4.6 mF = 94 mF capacitor bank with maximum voltage rated at 40 V which equals to 75.2 J of energy. Capacitor bank is charged via 2 A current source realized with U4 (LM317) - make sure to be able to heatsink 5 W average power...
Introduction Before doing this project, I ask myself if we can work, watch videos or playing games on a small screen. To do this project, I'm inspired by Paul Stoffregen's movie2serial project used with OctoWS2811 Leds to stream video playback. I invite...
MQ2 is one of the commonly used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact...
I've got a great neighborhood. It's pretty cohesive and busy. I also have kids who have friends in the neighborhood; all summer long, the door is constantly opening and closing as kids move back and forth between our house and theirs. There's also a...
The cottage has been extended at the back to house the electronics and below to hide the mechanism. The front window has a new frame to show off the LED temperature indicator.The mechanism is a double ended Watt's linkage which gives an approximately...
The control is on a windows PC running my C# code! This is a very non real-time setup but is doing the job really well. The C# is running a Thred.Sleep(0) thread which is measuring the time between each call. That is how I can call my kinematic function...
start of with a box of plywood 90cm x 40 cm x 40 cm drill a hole about 9cm diameter to allow for the extractor fan line the interior with aluminum tape at this stage i also installed a wire metallic mesh under which the lamps will be sitting (2 lamps...
Steppers motors deserve to be used in our projects much more than they are. Their use in 3D printers has brought the prices for the motors and drivers down dramatically. But the libraries to drive them lag behind. The Stepper library, part of Arduino,...
This project has reached its logical conclusion with all further development now continuing on the Arcus-3D-M2. Being born as a junkstrap, it inherently had a large number of variables to try to account for which was slowing development. Now that a clear...
What does it do? The badge is audio reactive so the 23 different LED modes move and react to the music. Components ESP32 -WROOM112 x SK6812-MINI RGB LEDSMicro USB with UART USB SERIAL plus USB Charging1500 MaH LiPo Battery Lessons Learned, Making...
Here's how it works: Clocks were pretty simple when it was just numbers on a dial and a motor turning the hands. it would be a lot simpler to just make an analog clock, but that would be boring! Keeping time with digital logic is pretty complicated,...
Arm segment lengths: Both 135mmShoulder range: -40 to +125 degreesElbow range: 0 to 159 degreesAngle 0 points toward positive X. Positive angles turn counterclockwise. If shoulder angle and elbow angle are 90, then the shoulder axis, elbow axis, and...
Inside of the enclosure there is a custom made PCB which is a WS2812B LED controller. Powered by 3.7v LiPo battery, ATTiny85 MCU with battery charging LED indicators and one button to controll them all. One click start the MCU, then you can switch animations...
This is the Smart Motor Driver (aka SAMI) designed to run a micro gearmotor, the objective of this board is to be able to implement a PID control easily over this motors with the corresponding RPM feedback using a hall effect sensor. So it has his own...
