Awesome attention to detail in this build, love the look of it. Great photos and a well written up build too! I have a couple of questions:
I can answer your first question there. This site supports markdown which works like shorthand for basic HTML.
Thanks for the compliments, I very much appreciate the feedback :) To answer your questions:
1.) As Whiffles points out, the site supports markdown. He linked an excellent cheatsheet with a great breakdown of all the available options. If you are interested in reading more about the reasoning and purpose of markdown's creation, see this link.
2.) Wet grass really shouldn't be too much of an issue, most of the components are capable of handling a minor level of moisture. If you are not looking for full on water proofing, some liquid electrical tape on the pdb is sufficient for keeping it from shorting against the carbon. Put some heat-shrink around your escs and mount them with double stick foam tape, (keeping them off the carbon as well). If you want an additional layer of protection wrap them with electrical tape, or seal the ends of the heat shrink with hotglue.
Feel free to hit me back with any additional questions you may have, I'm happy to help!
Oh awesome, I've used Markdown before but had no idea it was supported here! Thanks for your answers, sealing the ESCs with hot glue is a good tip, I may try that. So far I haven't had an issue with wet grass but I think I'll paint some liquid electrical tape onto the PDB just to be safe.
I'm not sure the liquid electrical tape is worth it. You'll just have a messy PDB that'll be hard to work with in the future.
Ultimately, doing any of this "water-proofing" adds an additional steps to any rework that may later be required. The nice thing about conformal coating is you can basically just use your soldering iron to burn through it. Hot glue and liquid electrical tape both require more work as you have to peel them away. That being said either method provides more protection than nothing, and, if I am working on the pdb it usually means I have had to disassemble the entire quad anyway. It's really up to the you what's worth it and what is not.
