One of the most important settings in FPV drone tuning isrates—they determine how your drone responds to stick inputs. If your rates are too high, your quad will feel twitchy and hard to control. If they’re too low, it may feel sluggish and unresponsive. In this tutorial, I’ll bre...
Before flashing firmware to the flight controller, make sure you make a backup of the existing configuration first, this allows you to revert to its original state if something goes wrong (very rarely you will need to, but better be safe than sorry). Here’s a tutorial onHow to backup Be...
Discover what is strain, its types, its relationship with stress, and a simple guide to calculate it for higher efficiency, improved measurement, and analysis.
It keeps stakeholders aligned and offers a clear vision and direction for the project team to follow. For example, why is the project being undertaken, what are its goals and who are its stakeholders? Project charters also help secure the approval and resources for the project. Get your free...
Test pH –this is done using a pH Pen, drops, or strips. Which one works best? Adjust pH by adding “PH Up” or “PH Down” solution. Your goal is to get your water in the right pH range for your growing medium. If your pH is too low, you need to add “PH Up,” and if...
A TDS meter is an instrument used to measure the total dissolved solids (TDS) in any given sample of water. It measures the electrical conductivity (EC) of the water, which is then measured in parts per million (ppm). TDS meters are used to measure the purity of drinking water. In mos...
DWC Reservoir ppm is too high/low: Too high:Add plain ph’d water to the reservoir and test. Repeat until your reservoir reaches a safe fill point, or the ppm is in the correct range. If the ppm is still too high, you can wait for the plant to lower the water levels, or you ca...
A timing accuracy of 25 ppm will be sufficient to calibrate most analog oscilloscopes and many DSOs, although a timing accuracy better than 0.3 ppm is required for some higher-performance DSOs. Why use square waves? In the past, timing markers have taken the form of a ‘comb’ waveform, c...
It takes 17.1 ppm to equal 1 gpg, as noted in this fact sheet from the Connecticut Department of Public Health. So, if your water hardness measures 100 ppm, that would equal about 5.8 gpg. How to Test Water Hardness at Home We won’t leave you high and dry or your water hard. ...
Offset accuracy is written as an absolute value, like “±0.02 mV,” which is easy to understand. Temperature drift can affect both the gain and offset accuracy. Gain temperature offset is written like “±50 ppm/K of reading ±200 μV/K,” for example. This ties the error directly to...
