created a tiny weather station based on the ESP8266:
Push the measured temperature, humidity, pressure and battery voltage to the cloud or local servers in defined intervals. Configuration is done by using a simple web browser.
MalteP has shared the board on OSH Park:
There’s a gritty feel to the Hackerboat project. It doesn’t have slick and polished marketing, people lined up with bags of money to get in on the ground floor, or a flashy name (which I’ll get to in a bit). What it does have is a dedicated team of hackers who are building prototypes to solve…

jeff on hackaday.io has designed a board for an Atmel microcontroller with the ARM Cortext M7 core:
Small Atmel SAM S70 based dev board. Similar to the Arduino Due, except super-mega-turbocharge
The board features:
- 300 MHz ARM Cortex-M7
- 2MB flash
- 384k RAM
- 480 Mbps high-speed USB
- MicroSD card
- Battery Charger

mobilewill was looking for a logic analyzer and found this BeagleBone-based solutions:
The BeagleLogic is a logic analyzer based on the Beaglebone created by Kumar Abhishek, a semi-finalist of the Hackaday Prize Best Product 2015.
The BeagleLogic features:
- 14 Channels
- Web Interface
What makes the BeagleLogic special is it uses the BeagleBone PRUs which are basically 200Mhz microcontrollers attached to the ARM CPU with shared memory. This is one thing that sets the BeagleBone apart from other SBCs.

Pesky Products created this convenient way to power Teensy 3.x from a LiPo battery :
This is an “appallingly small” add-on shield for Teensy 3.1 [..] The heart of the board is the MAX1555 battery management chip by Maxim Integrated.

Hackaday.io contributor extraordinaire [al1] has been playing around with small LEDs a lot lately, which inevitably leads to playing around with large groups of small LEDs. Matrixes of tiny RGB LEDs, to be precise. Where’s the LED?First, he took 128 0404 SMD RGB LEDs (yes, 40 thousandths of an inch on each side) and crammed them…

There are a ton of applications that we use that can benefit from keyboard shortcuts, and we use ’em religiously. Indeed, there are some tasks that we do so often that they warrant their own physical button. And the only thing cooler than custom keyboards are custom keyboards that you’ve made yourself. Which brings us…
