The Handy Board - The Cricket Robotics Controller

The Handy Board is a 6811-based microcontroller system that lets you build mobile robots for educational, hobbyist, and industrial purposes. People use the Handy Board to run robot design courses and competitions at the university and high school level, build robots for fun, and control industrial devices.

The Handy Board - The Cricket Robotics Controller
  • can control two motors and can accept two sensors, plus it has an expansion port for additional devices.
  • has a built-in infra-red port, so Crickets can communicate with each other.
  • is powered by four AA batteries.
  • is programmed using "Cricket Logo," a version of the powerful, yet easy-to-learn Logo language.



The Handy Cricket is a tiny robotics controller is much smaller than the Handy Board, weighing only a few ounces.

You can control motors and lights with the Cricket. The Cricket can receive information from sensors, like touch sensors and light sensors. Crickets can “talk” to each other, sending messages with infrared (IR) light. People have used Crickets to build little robots, animated rocking horses, automatic gift boxes, and other personal animated toys.

People have used Crickets to collect a bunch of temperature readings and look at them later. Crickets were developed at a major research university and now they are available to the public.

Electronique - Sonelec-Musique

Theory - This section is for beginners, and explains briefly what are the most common electronic components. Théorie - Cette rubrique est destinée aux débutants, et explique très brièvement à ce que sont les composants électroniques les plus courants. N'allez surtout pas là pour approffondir vos connaissances d'experts !

This topic is for beginners, and explains very briefly what are the most common electronic component. Réalisations - DIY (Do It Yourself, faites-le vous-même). Compilations de montages de mon cru, ou explications et conseils pour des montages d'autres auteurs.

Electronics - Achievements - Selector 001c

This circuit includes a microcontroller PIC 16F84A type (deprecated) or 16F628A (recommended), and can control one or more devices from eight through some pushbuttons. Each push button corresponds to a separate output, and Pressing either of these buttons activates the corresponding output.

"Drawing used model, designed by Flavie. few overviews and detail. 's eye is made ​​with a ceramic disc capacitor of 1.5 pF. The shoes are made ​​with four small rectangular capacitors of 1.5 pF. For the mane, forelock and tail, I used strands of copper wire. Wire has just been stripped and the copper is still pink. I hesitate to put varnish for protégrer corrosion."

8051 Macro Assembler ASEM-51

In 1979 Intel has introduced the 8051 as the first member of the MCS-51 family of microcontrollers. Today hundreds of cheap 8051 derivatives are available from dozens of manufacturers. This makes the MCS-51 architecture so interesting for professionals and hobbyists.

Intel had also defined an 8051 assembly language with bells and whistles for all the subtle peculiarities of the MCS-51 core, and offered a well-designed 8051 assembler, the legendary ASM51. Unfortunately, Intel obsoleted all its MCS-51 development tools in December 1993. The original (and IMHO best) 8051 assembler was gone and no longer available! ....... - W.W. Heinz,

ASEM-51 is a two-pass macro assembler for the Intel MCS-51 family of microcontrollers. It is running on the PC under MS-DOS, Windows and Linux. The ASEM-51 assembly language is a rich subset of the Intel standard that guarantees maximum compatibility with existing 8051 assembler sources.

"In the letter, they told me that they had used my ASEM-51 V1.2 to develop the motor-control software for a little Mars car prototype..."

They had validated several 8051 assemblers, and found ASEM-51 to be the most reliable and best documented one.
