Hardware Block SchemaHardware is built around the STM32F103 microcontroller. CPU timing is derived from an 8MHz crystal; it provides a clock stable enough for an on-chip USB interface to function correctly. An auxiliary low-speed precision 32.768kHz...
GKOS KeypadWith the 6 GKOS keys, directly connected to Arduino I/O pins, it is possible to type any text and enter most functions found on the PC keyboard (Alt, Ctrl, Tab...).GKOS HardwareThe GKOS hardware is very simple, requiring only six pushbuttons...
So what is this thing? At the most basic level, it's just some remotely-controlled water valves. How they're controlled and used is where things get fun. There are two main methods used to control these water valves: A simulated,...
Problem===========When our high tech devices die, all or most of the resources and effort that went into their production are lost. Either they are buried in a landfill, or they are recycled. If they are recycled, usually the task is accomplished by...
Objectives: receiving date and time from the DCF77 transmitter, decoding it, displaying it on a 128x64 pixel dotmatrix displayreceiving UTC from GPS satellites with a GPS module, displaying it on a 128x64 pixel dotmatrix displaystand-alone date and time...
[update 1/15/2016] Periodically, I notice in my email that someone has "liked" or "skulled" this project. Awesome, but... sadly, as mentioned in the last log update (more than half a year old, as of this intro), I pretty thoroughly killed this power...

Subsystems/Core FeaturesStructureShell- Each of face of Nautilus’ shell will be constructed individually from sheet metal or will be high quality 3D printed. This is cubic in shape.Hatch- One face of the ROV, the “hatch,” will open to allow...
The OWI-535 Robot arm is actually an excellent bit of engineering. Made of thin-walled injection molded plastic and a handful of small DC motors, it is very inexpensive, yet is a fully functional robot arm.It has three main drawbacks:It is a little bit...
The purpose of this project is to build as diversely functional multimeter as possible, using as little digital electronics as possible. At times it will be required to use something like a single 555 or basic logic, but nothing with nested or combined...
Before finishing the dry wall in my garage, I pulled some speaker wire to connect a pair of ceiling speakers in the garage to the receiver in the family room. Having some degree of foresight, I also pulled some thermostat wire to a wall plate in the...

This project was developed to create a new type of high altitude platform with enhanced real-time tracking and control. It will also be used to launch a rocket from the payload at altitude from the balloon payload (A.K.A. a Rockoon). The...
One-Off Solder Mask This document outlines how to take an EAGLE layout, a printed circuit board manufactured using the Protomat C60 circuit board cutter, Kapton tape (1 mil thick), and a Universal Laser VLS 3.50 to create a solder mask for your circuit...
