Pulse Generator 555


Pulse Generator project will generate a frequency in up to 180 KHz which can form a good test gear project.  This project is based on the classic 555 timer IC.


  • Input : 5-12 VDC Max @ 40 mA
  • Provides Square Waves
  • Range : Jumper selectable and preset tunable range of 1 Hz to 180 KHz
  • Power-On LED indicator
  • Berg connector for easy connection
  • Four mounting holes of 3.2 mm each
  • PCB dimensions 47 mm x 40 mm

Elektor DDS Function Generator


this is a DDS Funtion Generator by Theodorou Gerasimos:

DDS chips are readily available, greatly simplifying the design of the analog part of a wide-range function- or signal generator. All you need to do (they say!) is choose one, add some suitable output circuitry, pick a microcontroller, provide a user interface and start programming. To which we reply: sweet dreams, here is the real story: power to the AD9834!

PCI-Express Clock Generator

This reference design is a frequency generator for use in synchronizing a circuit’s operation. It consumes less than 50mW of power that specifically uses the IDT’s 9FGV0241 PCI-Express Clock Generator which is the lowest-power PCI Express timing family. It is a two output clock generator with programmable output amplitude allowing tuning for various application environments.

The circuit reduces heat dissipation to ease cooling requirements in large scale cloud computing applications. It has a programmable slew rate allowing tuning for various line lengths with an integrated output termination of 100Ω, providing maximum flexibility when working in a non-homogenous timing environment. In addition, the device has an external 25MHz crystal that supports tight parts per million (ppm) with 0 ppm synthesis error.

These clock synthesizers have various applications such as communications, computing, and consumer goods. Most members of IDT timing family feature a selectable SMBus address so that multiple devices can seamlessly share the same SMBus segment without the cumbersome additional logic that is often required with other solutions.

Scullcom Hobby Electronics #26 – Build a Function Generator Part 2

by Scullcom Hobby Electronics @ youtube.com

This is part 2 of the building a function generator. We cover the output stage and discuss some changes to the original design. Finally, we build the project in to a case and test.
Below are the links to the latest main schematic diagram and a second file for the Display and Arduino schematic.

Tiny and cheap lab generator


Bob build a tiny and easy to build function generator. He writes:

Function generator is a rely useful tool in the lab, a simple version can be build at home, there’s a lot of examples on the Internet, some are much more complex and powerful, but this one is intended to be really simple and cheap. It can be also built-in in some bigger projects that also requires a generator.

The generator can output (only) square signal with adjusted frequency and pulse width. The amplitude may be also modified by soldering different values on the voltage divider on the output, it’s a bit laborious, but if it will be used in digital or microprocessor projects, then there isn’t really need for amplitude adjustment.

A Bladeless Wind-Powered Generator


by elektor.com:

You don’t need to travel far in the Dutch countryside before you come across a traditional windmill. Now a consortium of Rotterdam-based companies are planning to build a massive wind-powered generator structure in Rotterdam harbor that will generate energy without using rotating blades. The innovative ‘Windwheel’ will work on the EWICON (Electrostatic WInd energy CONverter) principle developed at TU Delft and Wageningen University backed by a government economy/ecology innovation program.

The striking design has no moving parts but will use wind power to move charged particles (water droplets in this case) against the direction of an electric field. Charge will be transferred to a plate and then fed into the grid. Plans for the proposed generator structure are ambitious and indicate that it will contain a 160-room hotel built on seven floors, 72 residential apartments, a restaurant and other visitor attractions including an outer glass and steel ring structure containing viewing gondolas.

Video generator with PIC.


by Beke András @ bekeband.hu:

An black and white monitor needs to improve and repair from about 1990-th. The repair of device was not difficult but it caused troubles for the testing and setting of the monitor. We have a pattern TV generator, but this instrument are produce on the composite video signal for monitor. Unfortunately this monitor is demand not compozite signal instead of horizontal sync, vertical sync, and lightning signal. (video signal). Whereas the monitor host machine is not available – in fact I don”t know exactly what kind of equipment, perhaps a kind of mass spectrometer or something -, we need necessary a appropriate video signal source.
