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.

Your Chance to Win

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!

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.
