Paul Stoffregen of PJRC designed this shield as a Kickstarter reward earlier this year:

Ethernet Shield for Teensy 3.5 and 3.6

Please understand this shield has very limited software support at this time. However, Manitou’s early benchmarks show excellent performance we can someday hope to achieve as the software matures.

MicroUSB powered ESP8266 Oled Board

October 26, 2016 fustiniESP32, iot, OLED, wifi1 Comment

Mike Rankin created this board with a tiny OLED display controlled by an ESP8266:

MicroUSB powered ESP8266 OLED Board

I created this design as a challenge to make a design under 1″ x 1″ in size.

https://0miker0.wordpress.com/microusb-powered-esp8266-oled-board/

The hardware is an ESP-01 ESP8266 Wifi module, linear power supply, microUSB connector and a few oled display parts.

Mike Rankin created this adorably small WiFi-connected color OLED board:

ESP8266 Color OLED

I’ve been keeping an eye on the SSD1331 library to see if it would eventually work with the ESP8266 wifi modules. I noticed the support for it appeared one day with the Adafruit library so I tried it out on my Adafruit Hazzah and success!

Optical Convert Channels

One of our favorite hardware hackers, Joe Grand, has shared slides and hardware designs from his recent B-Sides PDX talk:

Optical Covert Channels

Data exfiltration from a device is usually achieved over the network, via hardware implant, or by manipulating the characteristics of an internal electronic component. Optical covert channels transmit data using visible light in a method undetectable to the human eye.

Joe demonstrates using an optical receiver to capture data transmitted through a LED:

Barbouri created a quad 7-segment I2C LED backpack:

Building a case for the Programmable Voltage Reference project

I put together an I2C interface board for these displays based on a design by Adafruit, using a Holtek HT16K33 RAM Mapping 16*8 LED Controller Driver chip.

A nice feature of this chip is a dimming command that provides display dimming in 1/16 increments.

Garage Parking Sensor Board

Chip McClelland created this visual aid for parking in a two car garage:

Garage Parking Sensor Board

Let’s face it, garages are simply never big enough. There is always more you want to put into a garage than will fit and once you park your cars, things get tighter still. To get the most out of this space, your car needs to be parked correctly everytime. That is what this little device seeks to do.

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

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.
