Precision MK.1
Jarvis Jan 14,2026
What is Precision MK.1?Precision MK.1 reimagines the standard robotic arm. While serial manipulators are effective, they lack the visual appeal of more experimental designs. Inspired by James Bruton’s Doc Ock tentacle that used stacked Stewart platforms, we wanted to push the concept further, but with less (and more?).About our DesignOur design is intended to withstand a maximum load of 5 lbs (more testing is needed), prioritizing maneuverability and range of motion over payload capacity. To ach...

Green Pill Nano: 1 uA sleep current, 10x RAM, real debugging, Arduino Nano Form Factor
Jan 08,2026
The original Arduino Nano is a classic, but it’s showing its age. Between its 32KB Flash limit, 2KB RAM, and a power-hungry 15mA sleep current, it’s nearly impossible to use for modern, long-term IoT sensor nodes or advanced battery-powered projects.I designed the Green Pill Nano to be the ultimate upgrade. It maintains the familiar Pin-Compatible footprint but introduces massive performance leaps:  - True Ultra-Low Power: Achieves a 1μA sleep current, allowing it to run for years on a...

LCD adapter
The Developer Guy Jan 07,2026
Free displays!Millions of disposable vapes end up in the trash every day. Almost all of them contain rechargeable Li-ion batteries, but some models have color LCD displays!Those come with fragile ribbon cables. This adapter PCB adds support, some power filtering (100nF and 1uF), and a limiter resistor for the LED backlight for convenience. (and 2 pin headers, one SMD, one TH, you choose)Just try not to break them while opening the case. I already broke 3!

PROTO216 Breadboard
Arcos Jan 07,2026
PROTO216 is a concept of protoboard design based on ISO 216 standard. The purpose of this concept is providing an alternative to traditional breadboards for prototyping, and increasing compatibility with other standards like Arduino.Traditionally breadboards are used for prototypes. They have two independent sides and connections are made using wires and jumpers. It's a cheap and easy solution to test new designs.So what's the main differences with the rest of protoboard solutions in the market?...

ZINO Alif Arduino UNo Compatible board
BENADDA Jan 04,2026
The ZINO Alif board is a compatible UNO board, designed to reduce cost, as the new version of this board commands higher prices. Moreover, since the latest versions are not open to the public, ZINO proposes an open version that includes additional features such as IR communication, NeoLEDs, and daylight detection.

Smart Motor Safety and Monitoring System Using Arduino Nano
S S Jan 03,2026
This project is a smart motor monitoring system using an Arduino Nano that keeps an eye on current, temperature, and vibration in real time. It uses an ACS712 sensor to track current, an LM35 to measure temperature, and a piezo sensor to detect vibrations. Whenever any parameter goes beyond safe limits, the system immediately alerts you with an LED and buzzer, helping prevent motor damage. All components share a common 5V supply and ground, and the motor connects via simple terminal pins, making...

Retro Style radio with CrowPanel 2.1inch round Display (TEA5767)
Pavleski Jan 02,2026
 Some time ago I presented you a clock project with CrowPanel 2.1inch-HMI ESP32 Rotary Display 480*480. In that project I did not use additional external components, but the display module itself downloads the data from the internet and displays it on the screen. The module also has the ability to communicate with an external device via I2C, so this time I decided to create a project that will demonstrate this ability. As you can see in my previous projects, I have made several radio r...
