2 Layers PCB 8.941 x 60.782 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen;
2 Layers PCB 22 x 89 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen;Hackaday project
2-layer PCB 38.7 x 49.5 mm FR-4, 1.6 mm, 1, with wire spray tin, red solder mask, white silkscreen; lightning detector.
Ardufocus is the only OSS/OSH controller to support two independent focus motors, the high-resolution mode allows for stepwise sub-micron movements, multiple acceleration profiles, and it never forgets the focuser position between restarts.
2 Layers PCB 54.6 x 90.2 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen;
Driver for WS2812, SK6812 or similar LED strips controlled via Bluetooth LE. It supports RGB and WWA LEDs. The drive uses motion and light sensors so in automatic mode it can turn on the lights when it detects the presence of someone in the dark.
A simple USB switch so I can swap a keyboard or mouse between two computers.
It is operated by 4 single mechanical switches, 1 for each channel. Simple designs can be implemented.
PCB for clipping onto Guillemot MAXI Gamer 3D Voodoo graphics accelerator. The common memory size for these cards is 4 MB. With the help of PCB you can get Voodoo up to 8 MB.
The basic Escornabot can be programmed to perform a series of actions using the robot's buttons. From this point of view, imagination is the only limit on possibility.
This circuit has everything you need to assemble a mClon-style robot, without the need to find the missing Arduino circuit from RobotDyn used in the ShieldClon version.
Components can be SMD or THT, except the boost circuit/lithium battery charge controller is SMD, the 1206 and 0805 components are larger than the usual 0603 and 0402). You can choose not to solder the boost smd component and just solder the Bat-Vcc selector on the bottom to use the power bank.
Based on ESP32, HC-SR04 ultrasonic sensor
1-layer PCB 50.1 x 79.9 mm FR-4, 1.6 mm, 1, tinned with leads, blue solder mask, white silkscreen;
This board was created for the mcudude library and has good voltage filtering, reducing reset time via a c10 capacitor (10nF!!) on the dtr line of a ch340 system. It would be nice to solder a precision socket under the x1 oscillator, it gives you the opportunity to try different frequencies (useful for rs232 communication for example)
It's common for computer users to bend over in front of a screen, which can eventually lead to back problems. There are various gadgets on the market that solve this problem by constantly reminding users to sit up straight, but most of them are not fun. So I made a fun little tool for this problem.
Do you need a small ISP to program your onboard AVR device? POGO ISP Micro is the right solution!
OpenFlops is a hardware open source floppy drive emulator/emulator inspired by the ubiquitous Gotek hardware. It is designed to run FlashFloppy firmware.
Breakout board for Lattice HX4K FPGAs with 10 PMOD connectors and onboard microcontroller for programming and communication via USB.
Detects Zero Cross point of AC supply (110/220VAC) and outputs a 1ms square pulse at 3.3V or 5V. 72mm x 20mm for DIN rail carrier mount.
2 Layers PCB 14.8 x 24.8 mm FR-4, 1.6 mm, 1, HASL with lead, Green Solder Mask, White silkscreen;For SMD 1117 Set Voltage O/P Regs - LED Indication
A small add-on board for the Raspberry Pi that I have designed specifically to solve the constant problem of shifting levels on sensors
