Logic Box - Diesel Fuel Injector Tester

Server.

The User Interface is a 32 x 128 graphic VFD and Proximity card reader with a Motorola 68HC908GP32 for display control and data entry.  The Ethernet connection and local game control is provided by a CPU board using the Rabbit 2000 processor.

Design tools used were Visual Basic 6, Transact SQL, Corel Draw 9, AutoCAD LT, Protel 99 SE, MS Word, Rabbit Semiconductor's Dynamic C Premier, and P&E Engineering's 68HC908GP32 assembler.

 

Arcade Game Control System

The Arcade Game Control System was developed for a Family Entertainment Center to replace the use of coins and tokens.  This system works using a Proximity card which is held near the User Interface to authorize game play.  The hardware seen here connects using Ethernet to a central game control computer to control all game authorizations.  Information regarding game play is then communicated to the accounting computers using MS SQL Server.

Arcade Game Control System v2

The v2 Arcade Game Control System was developed to cost reduce and improve the original game control system.

The User Interface is a 64 x 128 graphic LCD and Proximity card reader with a Motorola 68HC908GP32 for display control and data entry.  The new display has twice the screen area and is 1/5th the cost of the VFD and is easier to mount due to its smaller size.  The Ethernet connection and local game control is provided by a CPU board using the Rabbit 3000 processor.  This system had aditional functionality for connection to a larger variety of games and game room devices like vending machines and ticket munchers.

Design tools used were Visual Basic 6, Transact SQL, Corel Draw 9, AutoCAD LT, Protel 99 SE, MS Word, Rabbit Semiconductor's Dynamic C Premier, and P&E Engineering's 68HC908GP32 assembler.

 

Quickgrader - Teachers Grading Calculator

The Quickgrader was developed completely from a customer description and is currently manufactured by a Taiwanese calculator manufacturer in mid volume.  

A Windows program was written using Visual Basic to communicate the form and function of the calculator before committing to final design.  An existing Taiwanese calculator was chosen to minimize the up front tooling costs by using existing plastic.  The LCD was custom designed and the micro controller is an SPLD series "Chip On Board" made by Sunplus Semiconductor (This chip is only available for Taiwanese manufacture and development tools are hard to get in the US).  Design Tools used were Visual Basic 6, Corel Draw 9, AutoCAD LT, Protel 99 SE, MS Word, and Sunplus assembler.

Diesel Day Tank Controller

The Diesel Day Tank Controller was designed for a local company to manage the pumps on their line of Diesel Day Tanks.  These tanks work alongside commercial building emergency backup generators to provide a single days worth of fuel.

Design tools used were Corel Draw 9, AutoCAD LT, Protel 99 SE, MS Word, and P&E Engineering's 68HC908GP32 assembler.

 

 

Rock Climbing Wall Lane Timer

The Lane Timer is used to time races on a rock climbing wall.  Due to the limited customer requirements for quantity it was adapted from a Jameco JE725 clock kit.  The micro controller which shipped with the kit was left out and a socket was installed on the back side of the PCB.  This allows a custom CPU PCB (CPU08) to be installed which allowed for the Lane Timer functionality.  This functionality includes: Time in 1/100ths from .01 to 99m 59s and 99/100ths, Remote Start, Stop, and Reset switches, and remote RS232 time interrogation and control.

Design tools used were AutoCAD LT, Protel 99 SE, MS Word, and P&E 68HC908GP32 assembler.

The finished Lane Timer.  The digits are 2-1/2" (63.5mm) tall and the display is approximately 17" wide.
