Temp and Humidity + Time and Date on OLED

This project uses the Freetronics OLED Display and DHT22 module from Freetronics (with a few modifications to make it fit). It also includes a DS1307 RTC Module for time and 4 SMD LEDs for status. Put it in a case with a old NOKIA phone charger and switch and combine with Arduino and my OLED Shield and you get this a Temperature, Humidity and Time + Date on OLED Display.

Robotics Upgrade Module

A robotics upgrade module for any project requiring a brain. It features a Atmega32u4 MCU as the brain for the project and a number of add on features that can be selected via solder jumpers. It contains two motor controllers that use a 4081N AND Gate that use 6 I/O lines, three SMD status LEDs, on I/O lines A3-A5, a buzzer on D11 and I/O headers connecting power, I/O lines, reset and SPI. It also features direct USB programming via the MINI-USB connector with USB power select on JP1 used for choosing power. When on it uses USB when off it will use external power source. DO NOT HAVE JP1 ON WHEN USING EXTERNAL POWER!!! There is a 500mA resting fuses to protect the USB port from over load. External power is regulated via 7805voltage regulator. Adding to the module can be done by the I/O header. When controlling the motors D7 and D4 must be HIGH then direction is chosen by D5, D6, D9 and D10.

Left motor:

D6 = Right rotation

D9 = Left rotation

D7 =Activate

Right motor:

D10 = Right rotation

D5 = Left rotation

D4 = activate

Programming is done is C or the Arduino IDE being Arduino Leonard compatible. To download EAGLE CAD files go to https://github.com/jedhodson/Robotics_Upgrade_Module

Minecraft Raspberry Pi EDITION

Hi all

Today I finally got my raspberry pi to run the Minecraft Pi EDITION. Before I thought of trying the game I had changed the memory allocation to 16. Turns out the raspberry pi didn’t like that when running minecraft so it returned a ‘Fail Service. Already Running Error’ . So after changing it back to 64 it worked. There were a few down sides though. Yes it ran without much lag, but it didn’t have much in the inventory and world size wasn’t very big. It was very much like the iPod version. I plan on doing more with Raspberry Pi and minecraft (working on a server now).

Prototype # 1 – OLED Shield

My OLED Shield boards came today and were perfect. Only 2 small problems in R1 which didn’t really matter. They were a typo and the SDCD LED always on. I have only constructed the cable connector one.

Check out photos:
