You can do it and take credit for it.........if you want.I started a 100W flashlight but havn't finished it, been on the back burner a while.
Not sure what you are asking, different terminologies are floating around regarding dc-dc converters.Traditionally, if you are reducing voltage its "Buck" if raising v its "Boost"I think this would be a good universal low power converter.https://www.ebay.com/itm/3A-30-35W-DC-DC-Auto-Buck...Using a Buck converter with about 1-2 volts higher than output should be the most efficient.This seller has many types to study.https://www.ebay.com/itm/LM2596-LM2596S-DC-DC-CC-C...
That is the wrong type of step down module, LED,s MUST have a CURRENT limiting power supply, that one is voltage limiting only. Yes it will work for a while but if you drive the led near its rated wattage it wont last long. Look for a cc cv (constant current constant voltage) buck or boost regulator, they will have 2 adjustment pots on them.
Good job making this project. I would not have the patience.Why did I suggest buying? I am lazy LOL.
Just cover it with polycarbonate sheets, Small caliber bullets wont penetrate it. I'm pretty sure a football would just bounce off it. It is a nice project to learn from, but to call it cheap and simple is a stretch. But they do have their uses, like your stadium boards.
You do know you can buy a 65" 4k tv for $400.00 with almost 9 million pixels ???
Laying Out the Board
I hate to be a grammar nazi,but I do have a pet peeve about the use of the words Than and Then, they are not interchangeable words.An example of "Than" is, She can run faster than I can.It can be confusing if you were to say, She can run faster then I can.Which would mean I can run, but only after she runs faster.That sentence makes no sense does it?"Then" is commonly used as a reference of time. For example, I filled the car with gas then went to work.Here is a link that explains it much better than I can.https://writingexplained.org/then-vs-than-differen...If I wrote that as "much better then I can", it just wouldn't make much sense would it?It would sound like I could explain it AFTER the site does.
Kv will be the same. Brushless motors cannot be wired in series or parallel.To go twice as fast you would either double the Kv rating of the motor, Double the battery voltage, or halve the pulley reduction ratio. This is all theoretical, actual numbers will vary mostly from the power available from the motor itself. If the motor in this build is near its limit you would need to find a motor capable of about 4 times the rated watts, drag increases to the square of speed.
Tritium presents no external beta radiation threat when encapsulated in non-hydrogen-permeable containers due to its low penetration depth, which is insufficient to penetrate intact human skin. ... The primary danger from tritium arises if it is inhaled, ingested, injected, or absorbed into the body.

Solar wiring tip:Keep all the low voltage wires short as possible, reduces losses.Especially from battery to inverter.
I was replying to papaguns' problem of a broken but loose screw in a dremel mandrel. :)
If you dont know what something is, google is your friend....I kinda find it odd someone hasn't heard of left hand drill bits. Besides,the name of it is self explanitory.
I have been able to remove similar screws with a sharp pointed tool like a scribe or hobby knife, put the point against the screw and try to rotate it CCW.The broken screw will probably turn freely.2nd option try a tiny left hand drill bit.
