• BusPirate: A small open source device that connects a USB host device (PC, MAC, or cellphone / tablet via USB OTG) to electronic stuff. It can speak with several different busses (I2C, SPI, UART, etc...) and devices (LCDs, servos, AVRs, FPGAs, CPLDs, etc...) and can inject signals, or measure voltages. It's a little test bench in your pocket for less than $30. WIth the DroidScriptBusPirate, you can use an Andriod phone as a very easy User Interface.

Signal Generators

• Analog Devices AD9850 DDS has been used to design (Documentation, schematics, sources available at http://www.geocities.com/CapeCanaveral/Lab/9595/) a signal generator with the following features:
  • Uses two 16F84 microcontrollers, one for a 4x4 keyboard, the other for LCD, encoder, DDS, shift-register as DAC
  • Range 0.1 - 40MHz
  • Steps selectable from 1, 10, 100Hz, 1, 10kHz
  • Step multiplier selectable from 1-9
  • Frequency entry through keyboard in 1Hz precision
  • Keyboard commands to sweep frequency up or down
  • Keyboard command to 'wobble' frequency in 250 steps, with corresponding DAC voltage for oscilloscope X-input which is particularly useful for making measurements on filters.
  • Output level from 0 - +10dBm, level is held constant within 1dB over range.

• https://youtu.be/z6UJPqQYzNc Time Domain Reflectometer with a scope and a battery: The oscilloscope is set up with a tee connector on one channel; one side of the tee is connected to the cable under test, while the shield conductor of the other side is connected to the negative terminal of a 9V battery. A resistor connected to the center conductor is used to complete the circuit, which sends a brief pulse down the test cable. The scope is set up to capture the outgoing pulse as well as the return pulse, allowing the time between the two to be measured. Some simple math gives the length of the cable, the distance to a fault, or with a little rearrangement, the velocity factor of the cable.+

Questions:

• OK, I fixed the link. Thanks for helping me keep this page up-to-date. Have you tried a Google search for "PIC capacitance meter" ? -- David Cary

• nick sean omalley of cnetrica asks:

  • Hi, As a newcomer to electronics and microcontrollers, what would be the best type of scope to buy(if indeed it is needed)Analogue or DSO also what would be the minimum frequency I should go for, also are the Picolog PC based scopes suitable for uC projects. Thanks in advance
