In the Comments Below: Let Us Know Project Ideas around Data Conversion!
Your projects can explore either A-D or D-A techniques, or improve them in terms of increasing speed, resolution, linearity, reduction of noise or filtering of the analog signal.

| Monthly Theme | The January theme is Data Conversion and it was inspired by a suggestion from neuromodulator. Your projects can explore either A-D or D-A techniques, or improve them in terms of increasing speed, resolution, linearity, reduction of noise or filtering of the analog signal. Analog electronics and precision measurement are important for ADC and DACs. element14 Essentials: Analog Electronics 1 gives a good primer on this topic and it covers key parameters, characteristics, and applications of precision measurement analog ICs, including ADCs, DACs, voltage references, op-amps, audio amplifiers, and current sense amplifiers. .
Projects baldengineer suggest you could explore include the unique uses for ADC or DAC (e.g. capture something unrelated like light intensity to tell time of day) or comparisons (e.g. capabilities of microcontroller built-in ADC or DAC to dedicated components). You could convert from one quantity to another such as converting sound to light level (ADC the sound, DAC the light level). You could also DIY ADC or DAC (e.g. can you build your own Sigma-Delta converter using 7400-series chips?) or demonstrate the importance (or non-importance) of Bits (eg. built circuits that show the difference between 8-bit and 10-bit ADCs. or 14-bit and 16-bit DACs). Does one matter more than the other?). Finally, you could work on circuits or projects that use a DAC or ADC, but not a microcontroller.
Some examples of projects shabaz came up with include data acquisition and charting (Brewing beer with Raspberry Pi) ; seismology (TI LDC1000 Evaluation Module ) ; switched capacitor, and sample and hold based circuitsswitched capacitor, and sample and hold based circuits; detecting sounds (Vibration Sensor and Exercising - Calculating FFT on Nucleo Board - Blog #3 ); signal generation (Building A Direct Digital Synthesis Dual-Channel Signal Generator ); medical sensing (MagicHat - 6 - Heart beat detection ); power monitoring (Turn your Avnet Azure Sphere Starter Kit into a Power Meter / Data Logger ), software defined radio (Software Defined Radio (SDR) - My First Design ), and distance learning (Virtual Eye System -- Post#4 -- Programming the Pi to get the distance ). Projects can involve ADCs or DACs, or analog data could be sampled or filtered or converted to a different domain, signals could be extracted or synthesized, speech processing, instrumentation, SDR and so on.

What are Monthly Theme Polls?
| 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!
Visit: Data Conversion or tag your project blog DataConverCH
You have until March 16th End of Day to submit your completed project!
A jury consisting of your peers will judge project submissions! |
