Welcome to Hirstbrook! - where knowledge flows.

• SUN SPOT Project ---Sponsored by Sun Microsystems "Change Your World" grant

• Mobile Studio Desktop - Link to Howard University Mobile Studio Lab Page : Computer-based lab which replaces most of instruments and they are realized inside a computer (desktop, laptop, and Tablet PC), along with an interface ("IOBOARD") which measures, displays, and communicates.

• CLASS NOTES - Circuit Theory I and II, Electrical Eng Lab, Energy Conversion Lab, Microcomputer, etc

• THE OTHER SIDE of CIRCUIT THEORY (Not ready yet)- Unorthodox and Alternative Approach to explain circuit theory

• Embedded Computing with PIC 16F877-Assembly Language Approach:A complete guided project book for PIC students - Topics covered, with full assembly source codes, are: Circuit Diagram with RS-232, Bootloader, Hex code download, LED light on/off, Piezo-electric buzzer application, LCD and series LCD connection, AT Keyboard connection, Voice synthesizer connection, DC motor control and Robot application, IR remote control (Sony and Sharp Protocols), Unipolar and Bipolar Stepper Motor control application, Motor control relays and ICs, PWM application, I²C bus connection and external serial EEPROM application, Internal EEPROM read/write application, Robot arm control application, Timer module and digital clock application, A/D conversion and data acquisition, Serial communication module and software-enabled serial communication, and so on. Again, complete source codes and subroutines for each every application and subject.

• PIC START: Before your first coding practice, and before your long steps to the PIC programming, you have to check if you have everything you need. You don't want to stumble at the start line and you don't want to see your PIC engine fizzle out. This site guides you through detail explanation for (1)what minimum hardware you have to have for your PIC project, (2) how to select a proper 16F877 or 16F877A chip for the project, (3) where you get a bootloader, (4) where you find a PIC burner to burn your PIC16F877 pr 16F877A bootloader, (5) where you download the PIC downloader (which downloads your own hex code to the bootloaded PIC chip), and (6)other important stuffs you have to check before ignite your PIC engineer. A must read for all beginners.

• IEEE Education Society - Washington/Baltimore Chapter [E25 JT.BALT/WA]

This site has, in addition to my lecture notes, some other interesting stuffs like mobile studio pedagogy, robot team activities, and previous projects of my students. The class notes contain: Circuit Theory (or Network Analysis), Microcomputers (Motorola and PIC), and Embedded Computing with PIC 16F877 Microcontroller.

The class notes below explains and describes various topics for electrical engineering students. Topics covered include, but not limited to, Ohm's law, KVL, KCL, Node voltage and Mesh current methods, Source transformation, D'arsonval movement and meter scaling, Thevenin equivalent circuit, delta-to-Y conversion, capacitor and inductor, Op Amps, transient circuits of first order and second order.

 

Also, there are very detailed lectures on PIC16F877 microcontroller in the notes. The electronic textbook used for Microcomputer and Embedded Computing courses are also available in the site. Sample chapters are freely available for browse, and one can purchase the book with minimal payment. See the Embedded Computing with PIC 16F877 Book (A complete guided project book for PIC students). Topics covered, with full assembly source codes, are: Bootloader, Hex code download, LED light on/off, Piezo-electric buzzer application, LCD and series LCD connection, AT Keyboard connection, Voice synthesizer connection, DC motor control and Robot application, IR remote control (Sony and Sharp Protocols), Unipolar and Bipolar Stepper Motor control application, Motor control relays and ICs, PWM application, I²C bus connection and external serial EEPROM application, Internal EEPROM read/write application, Robot arm control application, Timer module and digital clock application, A/D conversion and data acquisition, Serial communication module and software-enabled serial communication, and so on. Again, complete source codes and subroutines for each every application and subject. Don't forget to read PIC START page before ignite your PIC engineer. A must read for all beginners.

 

Since this page is available anywhere in the world, so my purpose of serving my students is now much more expanded without limit. My definition of a web page is a minimalist approach: maximum information dissemination with minimum house keeping. Therefore the layout of the web page is plain and blank, however, I try my best so that the information would be colorfully rich.

I hope you all enjoy the learning process in engineering education.

Your comment and suggestion are always welcome to further improve the site.
