Creating A PCB In Everything: Eagle, Part 2 — Hackaday

In the last (and first) post in this series, we took a look at Eagle. Specifically, we learned how to create a custom part in Eagle. Our goal isn’t just to make our own parts in Eagle, we want to make schematics, boards, and eventually solder a few PCBs. The board we’ll be making, like…

Making A PCB in Everything: Eagle, Part 1 — Hackaday

For the first in a series of posts describing how to make a PCB, we’re going with Eagle. Eagle CAD has been around since the days of DOS, and has received numerous updates over the years. Until KiCad started getting good a few years ago, Eagle CAD was the de facto standard PCB design software…

Atmel SAMD21G Sensor Board

Mike Rankin created this tiny sensor board with an ARM Cortex M0+ microcontroller and OLED display:

0miker0’s Blog: SAMD21G Sensor Board

It’s pretty tiny so a 4 layer board made the whole job easier. The top and bottom are pretty much dedicated for components, layer1 are tracks and power traces, layer2 is a ground plane. Mixing up an internal plane and routing layer was interesting.

The hardware consists of:

  • SAMD21G18A processor (used in the Adafruit Feather)
  • HDC1080DMBT temperature/humidity sensor
  • ADXL345B accelerometer
  • DS1340U RTC
  • MCP73833 LiPo battery charger
  • MicroSD card connector
  • Navigation Button and pushbutton
  • 0.66″ mono oled display
  • Micro USB connector for charging and uploading new sketches

 

The design files and source code are available on GitHub:

Wearable Navigational Aid for the Blind

Neil Movva created this wearable project to assist the blind:screenshot-at-2016-09-20-10-57-32

Pathfinder – Haptic Navigation

wearable device that translates distance into haptic feedback. Users just wear the wristband (or glove) and point at objects up to 500 centimeters away, and feel gentle pulses at their fingertips corresponding to the object’s distance

Fish Food Lure for MinnowBoard

The MinnowBoard is an Open Source Hardware single board computer with 64-bit Intel Atom processor.  Jose Navarro created this “lure” board to simply connecting the MinnowBoard to a breadboard:

Fish Food Lure

Fish Food Lure, breadboard adapter for the MinnowBoard MAX / Turbot compatible boards (because you feed bread to fish). Enables fast prototyping on a breadboard, connects to the MinnowBoard using a ribbon cable.
