SpecScope from NFX Development

This is an interesting attempt in the right direction. The bandwidth may be only the audio range, but the first instruments with touch interface for tablets are being built for tablets even by DIY Enthusiasts.

SpecScope from NFX Development

SpecScope is a spectrum analyzer and is the second in the line of engineer applications from NFX Development. The SpecScope incorporates the speed and ease of use to access FFT frequency measurements in a hurry.

SpecScope from NFX Development

Some of the Features
  • Logarithmic/Linear measurements
  • Pinch to zoom in both X and Y axis
  • Selectable No. bin for accuracy versus speed
  • Three settings of spectrum averaging
  • Threshold trigger to hold the peak value
  • Tap to pause and resume measurements (graph is still navigational in this mode)
  • A adjustable sample rate allow analysis from 10 Hz to 22KHz

Tuxgraphics AVR Microcontroller

You will find tutorials on how to build your own avr programmer, a digital DC power supply, a tiny web server, an ethernet weather station, usb slide show presenter and lots more.

Tuxgraphics AVR Microcontroller

digital DC power supply unit - A very small an really good DC bench power supply unit for your hobby lab. It has lots of features which you normally find only in very expensive power supplies. This one is affordable, small and easy to build.

Temperature and humidity measurements with the AVR web-server - Just add this one SHT11 sensor. No other components are needed to measure temperature + humitidy + dew point.

Mini 3 digit display, a small and inexpensive voltmeter module - We build a simple and inexpensive three digit display. It's a voltmeter module but it has also gerneral purpose digital IO pins.

Raspberry Pi and MSO-28 Virtual Scope

PiMSO, is a Raspberry Pi controlled 200Msa/s mixed signal oscilloscope.  PiMSO, a spinoff of WebMSO, is an experimental project to understand the necessary components required to deploy the MSO-28 mixed signal oscilloscope on mobile devices.

The PiMSO lets you run a USB based Oscilloscope/Logic Analyzer from a Raspberry PI. The Oscilloscope is controlled via the browser on phone, tablet, PC or MAC. The connection to the host is via WIFI or Ethernet.  PiMSO consists of eight parts:

 Raspberry Pi and MSO-28 Virtual Scope

The MSO-28 is a 2 GSa/s Oscilloscope and 200 MSa/s Logic Analyzer. It is extremely portable.

The MSO-28 has time synchronized oscilloscope and logic analyzer inputs. All 10 channels are sampled at the same time and are displayed together. This is better than separate instruments because the analog and digital waveforms are acquired with the same sample clock assuring accurate time correlation between the two.

Add a RaspberryPi or Intel Edison for remote operation via the web.  Control the MSO-28 remotely from your Android, IOS or web browser.

Build Your Own Microcontroller Projects

These pages created by Wichit Sirichote of  Department of Applied Physics, Faculty of Science, provides schematic and software for hobbyists to practice "learn by doing", build a simple microcontroller projects at home.

Build Your Own Microcontroller Projects

Some of the projects include - The 4 Channel Pt100 Thermometer, G5-Data Logger, Solar Recorder,    89S52 and PIC Project Board. Even circuits, code and SBC for the popular 8051 can be found here.

Dual Channel Digital Volt Meter

"I do remember the Intersil ICL7135 very clearly. This year 2011, almost 29 Years, the classic integrating type analog to digital converter is still interested. With a cheap price and easy interfacing, I think I will design a cheap digital volt meter with microcontroller to provide serial interface similar to the Fluke45. Two channels is good for scientific experiment."

Keysight Technologies - Test and Measurement

"From a small garage in Palo Alto, California, to employees around the world serving customers in 110 countries......."  Changes that happened --- hp >> agilent >> Keysight Technologies

Please Note - Just like HP who started as a T&M Equipment firm, hived off the founding Niche as Agilent, Now Keysight holds that root Niche of T&M that companies like Fluke, Tek and Rohde & Schwarz belong.

The company founded by William "Bill" Redington Hewlett and Dave Packard was know as Hewlett-Packard Company or HP. This was a Test and Measurement company. First popular product was a precision audio oscillator, the Model HP200A.

Later Computer and Printer products divisions retained the brand and firm and Agilent was spun off for for the Test and Measurement and other non-computer product line.

34405A Digital Multimeter, 5½ digit

"The 34405A comes with a broad range of measurement functions, including temperature and capacitance measurements. The 34405A features simultaneous reading of DC and AC measurements with its dual display and can take up to 19 readings/sec at 4½ digit resolution through the standard USB interface."
