Low power Arduino Pro Mini board

November 18, 2016November 18, 2016 fustiniarduino, ATmega328, atmel, avr, Data Logger, hackaday, Low Power1 Comment

Max.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

Hardware

Microcontroller: Atmega328p with Arduino bootloader
Real Time Clock: MCP79410
Voltage Regulator: MCP1700
FDN340P MOSFET

Features

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

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 […]

davedarko wrote in his LED displays on Arduinos – a collection project log on hackaday.io:

Arduino Pro Trinket – bubble display

With 4 of HP QDSP-6064 bubble displays in a drawer I felt ready to do something with them and the “Clocks for Social Good” – call on hackaday.com finally got me going

The design files are available on GitHub:

Hackaday was in Portland last weekend for the Open Hardware Summit. I did a brief recap earlier this week but this post has been on my mind the entire time. The night before the summit, OSH Park (the Purveyors of Perfect Purple PCBs which we all know and love) hosted a Bring-A-Hack at their headquarters. [Laen]…

Get together with awesome hackers and build something cool. That’s the exact description for the workshops of the Hackaday SuperConference. Previously we announced all of the talks and some of the workshop presenters, but starting right now you can reserve your space in these inspiring hands-on sessions. You must have a SuperCon ticket in order to…

Friday was the 2016 Open Hardware Summit, a yearly gathering of people who believe in the power of open design. The use of the term “summit” rather than “conference” is telling. This gathering brings together a critical mass of people running hardware companies that adhere to the ideal of “open”, but this isn’t at the exclusion…

A Completely Open Microcontroller

An annotated mRISCV die imageI don’t know about you, but the idea of an Arduino-class microprocessor board which uses completely open silicon is a pretty attractive prospect to us. That’s exactly [onchipUIS]’s stated goal. They’re part of a research group at the Universidad Industrial de Santander and have designed and taped out a Cortex M0…

Not only have [onchipUIS] successfully bonded their chip, but they’ve done so using a chip on board process where the die is directly bonded to a PCB. They used OSHPark boards and described the process on Twitter.

You do not know how to make a PCB unless you can make your own parts. [Jan] knows this, but like everyone else he checked out the usual online sources for a footprint for an SD card socket before making his own. It turns out, this SD card socket bought from an online marketplace was…
