The MightyWatt: a 70W Electronic Load Kit

of Kaktus Circuits created this programmable electronic load that sits on top of an Arduino:


The MightyWatt: a 70W Electronic Load Kit

Electronic loads are used to draw power from a source at either a constant current or a constant voltage. This comes in useful for things like battery discharge testing or making sure that PCB you designed can actually power those motors without releasing the all important magic smoke.

The kit is sold on Tindie:


MightyWatt turns your Arduino Uno R3, Arduino Zero (M0/M0 Pro) or Arduino Due into an electronic load capable of dissipating 70 Watts in a very small form factor. Ideal for testing power supplies, batteries, fuel cells or power amplifiers.

Creating A PCB In Everything: KiCad, Part 1

This is the continuation of a series of articles demonstrating how to Create A PCB In Everything. In this series, we take a standard reference circuit and PCB layout — a simple ATtiny85 board — and build it with different PCB design tools. Already, we’ve taken a look at the pre-history of PCB design with…

HydraESP32: HydraBus and ESP-32S

The Espressif ESP32 features a 32-bit 240 MHz dual core processor with  Wi-Fi and BLE. HydraBus created this shield for ESP-WROOM-32 or ESP-32S.


HydraESP32 v1.1 Rev1 with ESP-32S is alive

This shield can be used with or without HydraBus board, you can even cut HydraBus specific right side (on the line) to have a tiny ESP-WROOM-32 breakout board.

hydrabus has shared the board on OSH Park:

Low power Arduino Pro Mini board

3317771479151537261.JPGMax.K created this Arduino Pro Mini compatible development board for low power applications:

LP Mini

ideal for data logging over extended periods of time [..] can run for months or even years on a coin cell



  • Microcontroller: Atmega328p with Arduino bootloader
  • Real Time Clock: MCP79410
  • Voltage Regulator: MCP1700


  • 2.8 µA current consumption in sleep mode
  • Compatible to the Arduino Pro Mini (except for pin 2 and 10)
  • A real time clock keeps the time and is used to wake the Atmega from sleep mode
  • Sleep current is reduced by using a more efficient voltage regulator
  • A simple Mosfet is used to turn external devices on and off if the IO pins cannot provide enough current

Simula Robotic Organisms


Chicago Robotics Corp is exploring 3D Printed Robotics with Simula:

simulated life-forms for use in research and entertainment

The robot is programmed with Arduino IDE:

Programming Simula

You might choose to program Simula by yourself from scratch, modify our existing software, or just keep up with our latest simulations.

Arduino Library for the Simula Boards and Modules is on GitHub:

Gathering for Open Science Hardware


The Gathering for Open Science Hardware (GOSH) is new annual conference for those building and using Open Source Hardware (OSHW)  for scientific research:

The GOSH movement seeks to reduce barriers between diverse creators and users of scientific tools to support the pursuit and growth of knowledge.

GOSH 2016 took place at CERN last March with an excellent keynote by Javier Serrano:

Open Hardware at CERN – a quick introduction

Vinduino: Save 25% Of Water Needed For Irrigation


wrote on the Tindie blog:



Vinduino – Save 25% Of Water Needed For Irrigation

Vinduino is one of those projects that set out to solve a really big problem which straight away makes it interesting. Reinier van der Lee wanted to use the least amount of water possible for irrigation in his southern California vineyard.


Hence the Vinduino project was made to be a relatively low cost system to help save on water use. It is also solar powered, further reducing its impact on the environment.

The Travelling Hackerbox Is Going International

Over the last year, Hackaday.io has seen an incredible project. It’s a migratory box of random electronic junk, better known as the Travelling Hackerbox. The idea behind this mobile electronic surplus store is simple: receive the box, take out some cool electronic gizmos, add some of your own, and send it on to the next person […]

Give Your RPi a Cool FPGA Hat

Need additional, custom IO for your Raspberry Pi? Adding an FPGA is a logical way to expand your IO, and allow for high speed digital interfaces. [Eric Brombaugh]’s Icehat adds a Lattice iCE5LP4K-SG48 FPGA in a package that fits neatly on top of the Raspberry Pi Zero. It also provides a few LEDs and Digilent compatible PMOD connectors […]
