Simple 555 Simulation Software

Each stage provides an array of design wizards, circuit blocks and information panels that facilitate the use of the 555 timer in projects. Component value calculations for the 555 take into account the supply voltage, timer fabrication (CMOS or Bipolar), and, where appropriate, load currents.

555 Timer Project Design Software for Beginners and Experts

555 Timer Project Design Software for Beginners and Experts

22 timer design wizards - 14 for the astable mode, 8 for the monostable mode

input circuitry - for gating an astable or triggering a monostable. Input categories are switch, touchplate, continuity, liquid level, AC detect, light, sound, and temperature.

counter wizards - facilitate divide by/count to strategies using common binary and decade counters
output circuitry - that can be activated by the 555 timer. Includes switching loads, driving motors, driving LEDs, lamps, numeric and bargraph displays, and audio, ultrasound and RF outputs

555 Timer

This program allows you to calculate Resistor and Capacitor values for both Astable and Monostable modes.

8051 Single Board Computer

New Microprocessor learning board demonstrates exemplary design of 8-bit single board computer. More peripheral and easy to adapt to be a dedicated controller.

8051 Microcontroller Kit

8051 kit using 7-segment display and hex key monitor. The design is simple, small number of components and cheap. The size is compact, 5.3x5.7 inches. The keypad is ergo design for young students. The kit is 8051 based microcontroller. So many chip makers produce the 8051 core microcontroller. The kit is available for both preassembled and kit form.

 8051 Microcontroller Kit

8051 Single Board Computer

The new 8051SBC features;
  • CPU: Any 8051 compatible with 40-pin DIP package @11.0592MHz
  • MEMORY: 27C256, 32kB EPROM for monitor program
  • 62256, 32KB SRAM for both code and data space
  • I/O: direct cpu bus interface 2x16 line LCD
  • MEMORY and I/O Decoder: GAL16V8D
  • EEPROM: 24LC256, 32KB serial eeprom
  • RTC: Real-time clock, DS1307 with +3V Lithium backup
  • ADC: LTC1298, SPI interface 2-channel 12-bit Analog-to-Digital Converter
  • I/O pins: P1,P3 of 8051 cpu, 16-bit I/O port
  • Keypad and DIPSW: 4-bit keypad and 4-bit DIP switch
  • RS232 Level Converter: MAX232
  • RS485: 75176 differential transceiver
  • Serial Interface: 9600 8n1
  • Monitor Program: Modified PAULMON2 including new commands
delabs Notes -
 
This is an Educational Masterpiece, with more Relevance to Asian Students. I took my first steps with 8085, Z80 and later 8749. Then the 80C51. If you start writing code for 8080, you will want features which will come in 8749 and when you study 8749 and think of enhancements 80C51 will pop out as if they read your mind.

Once you work with these, then you can use all the new uC and uP easily. It is better you write code with as less EPROM or Flash as possible. This will help you make quality code. The smaller the code the more real time your firmware and lesser bugs.

MakerSpace Hackerspace and TinkerSpace

I am using the word MakerSpace for the same Hackerspace. I would rather call them plain TinkerSpace, where youngsters take apart, fix, build Hardware, Software, Webware, Robots and Machines.

MakerSpace Hackerspace and TinkerSpace

Sony used to get the abandoned ww2 radios in the islands to design, make and sell their first radio units. Honda used to fix bikes from europe and america to gain the skills and mutate to a global giant. Take apart, reverse engineer, fix and learn.

Hackerspaces are community-operated physical places, where people can meet and work on their projects.This website is for 'Anyone and Everyone' who wants to share their hackerspace with international hacker's'paces.

Every kid is a born hacker and he starts with his toys, his mom does not like that, but he does not stop. One day he is building something pretty big.

Dallas Makerspace Wiki - Membership based, non-profit, shared community workshop and laboratory.

Milwaukee Makerspace - Social club for people who like build, invent, tinker and/or collect new skills and expand their minds.

In the late nineties and the early 2000. There were Hobby DIY Groups, Ham Radio Groups and Learning Electronics Communities. Hackerspaces by function, may be as old as technology itself. People working in a garage or shop to learn skills or build-invent something, but with different names like "Metal Tinkering Club" etc..

Recently the people at Make created a more organized and sustainable movement, that is helping the "MakerSpace" Phenomenon Emerge - Makezine - MAKE brings the do-it-yourself mindset to all the technology in your life.
