Project14 | DIY Test Instrumentation: Build Your Own Test Instrumentation!

 

Give Us Your Ideas on DIY Test Instrumentation Projects in the Comments Below!

 

 

The theme this month is DIY Test Instrumentation .   If you're getting started, it's a fun way to explore design & electronics projects while making something useful. You'll find examples on this page to encourage you to get your hands dirty with microprocessors, development boards, soldering, and tinkering.  DIY test equipment projects will further your understanding of how electronics work. If you are a design & electronics enthusiast, this is an opportunity to make homemade tools & instruments that fits your needs, at a fraction of the price of more expensive equipment.

 

Examples of DIY test equipment include oscilloscopes, function generators, audio impedance meters, capacitance meters, AC/DC LED Indicators, 554 Timer IC Tester, digital frequency counters, digital pressure guage, MOSFET tester, wire tracers, tachnometers, mains power line sniffer, and digital voltmeters.

 

If you're an electronics & design enthusiast, you probably spend as much time fussing over your hand tools as your hand instruments.

 

Here are some examples of projects that you can do:

Be Original
Stick to the Theme
  • You could come up with a clever name that make's your project memorable!
    • This project is your baby! Part of the fun of bringing something new into the world is coming up with a name.
  • Your project could introduce something new or that is not commercially available or affordable!
  • If you have an idea for a project that doesn't fit the current theme then submit your idea in the comments section of the monthly poll.
List the Steps
Submit Video Proof
  • Provide the steps you took to complete your project (text, video, or images).
    • This could be a step by step how-to-guide, vlog, schematics, coding, napkin drawings, voice narration, or whatever you think will be useful!
  • If it doesn't work that's fine, this is more about the journey than the end product.
  • A short video is all that is required but you can shoot as much video as you like.
  • You are encouraged to be creative and have as much fun as possible!

About Project14
Directions

Every month you'll have a new poll where you'll get to decide an upcoming project competition, based on your interests, that will take place a couple of months in advance. Themes are broad in scope so that everyone can participate regardless of skill set.

 

What are Monthly Themes?

  • Every month (around the 14th of each month) a new theme will be posted on Project14.
  • Submit your ideas (proposals) for your projects to get feedback from the rest of the community.
  • Submit a project entry in the Theme space once you start working on it.

 

What are Monthly Theme Polls?

  • Every month (around the 14th of each month) there is a project theme poll.
  • Vote on which project competition you want to see for the following upcoming theme.
    • The themes voted on during the previous poll decided the upcoming theme.
    • If you submit an idea for a theme that is not used then it can still be used in a future poll.
  • Themes comments and ideas from the comments section of the project theme poll.



Step 1: Log in or register on element14, it's easy and free.

Step 2: Post in the comments section below to begin a discussion on your idea. Videos, pictures and text are all welcomed forms of submission.

Step 3: Submit a blog post of your progress on your project by the end of the month.  You are free to submit as many blog entries as you like until the beginning of the next theme.

 

Be sure to include video proof of your project!

You have until any time on August 16th to submit your completed project!

 

A jury consisting of your peers will judge project submissions!

  • I've submitted an entry: a PWM generator for half bridges, with a Xilinx Zynq FPGA.

    It's the outcome of a self-train exercise that I've been posting about lately.

  • House environmental monitor with variety of temperature, temp-humidity-pressure, particle counters, light sensors, and gas sensors kicking the results to a touch screen display that cycles automatically.

    I would love to build something for current measurement using RapsberryPi and TLI4970 current sensor from Infineon.

     

    The LCD display to display current.

  • Very good contest by element14. Many electronics enthusiast has some kind of equipment at home that stays in the box without being used.

    I have some kind of NE555 time IC's, Capacitors, Registers in my box. I would love to build something out of it/

  • I would like to pursue my "Cable tester but I will have to use an Arduino instead of my VME hardware (too much time) so hears the drill  this is sort of a Flying Probe Style..

    First I have a DB25 wired to my Arduino using digital pins most likely high. then the probe is ground.

    The Arduino will guide me and tell me what in to probe next. I would like to use 2 DB25s that will get me to a 50 pin count. I will most likely have two RJ45s to test network cables.

    If I do use 2 DB25s I now can test cables as well.

    and that should do it.
