VirtualBreadboard(VBB) is for designing and testing embedded software in high-level interactive circuit simulations and rapidly prototyping hardware from those designs.

Virtual Breadboard – Test Embedded Systems

Compared to other simulators many people find the high level approach taken VBB easier to use and much faster to model and test out new ideas and circuit variations.

From Design Gopher – Electronic Product Development

VBB electronic circuit components are modeled at the function block level and are wired together to create a real-time interactive circuit simulation representing the whole embedded application.

VBB does not use SPICE. SPICE is better suited to subcircuit designs whereas VBB is concerned with merging multiple subcircuits treating each subcircuit as a self contained function block.

RT Software Oscilloscope GUI DLL Library

“The library makes it possible to show on the beams of the oscilloscope over a million quantization steps of signal per second (on the Pentium III machine) – less than one micro-second is sufficient for one signal sample. This software can be used for linking to real-time controlling programs as longer delays in relay of data to the oscilloscope don’t occur.”

RT Software Oscilloscope GUI DLL Library

Universal Real-Time Software Oscilloscope GUI DLL Library

“The library is supplied with a comprehensive description of the program interface and simple examples of its use executed in various different program development environments: MS Visual C++® & Visual Basic®; Borland Delphi® & C++Builder®; MathWorks Matlab® & Simulink®, C# (C Sharp).”

“Applied software emitting data to this oscilloscope obtained data via such communications as serial port (RS232, 422, 485), SSI, USB, CAN bus, Ethernet, GRIB (instrumental interface), via custom-made communications equipment and also by collecting information via a data acquisition card with analog-to-digital converters mounted on the PCI bus-bar of a PC.”

delabs Notes -

I am amazed, i did not notice this. I tried it it, not fully, it seems to be quite versatile. I feel this may be useful for hobbists to try out some experiments in oscilloscope and logic analyzer. It would be good if it was Open Source, it may help developing more instruments.

I am not sure about this Library in terms to actual high speed testing or if it may be developed further. But is it interesting.

For students i feel Bitscope offers some nice tools too. BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes.

Easy to Build Lux Meter - ELM

If you are building LED Lamps and Solar powered lighting, a LUX Meter and a Energy Meter is required to measure what has been achieved. One is the Efficiency of Power Conversion and Other is Illumination comparable to the lighting people are used to. It would be better like a Mains Supply wiring, 230/110 all [...]

MakerSpace Hackerspace and TinkerSpace

I am using the word MakerSpace for the same Hackerspace for just one reason, many conservative regions in the world are spooked silly when you say the word hacker. I shall use this word Maker so that youngsters and students are not barred from MakerSpace from these regions. Finally i would like to say that [...]
