    I do using files not rasp thought that things destroy my suit. the purpose of buying tools is so that I can sand the left over from files since it's too thick and I rather use machine cause using sandpaper is a pain and very long.

    oh hello there!! i am currently running a single 12v fan off a 9v battery. while it usually lasts through a full con weekend, it is completely inconsistent with fog prevention (i always pair with rain-x anti-fog on my face shield anyway), so i am looking to improve airflow. i plan to cut out the cheek hose area on the inside and make slashes through the hoses themselves, and i would like to place one fan on each side (one for air in, one for air out). i would like to get another fan, but don't want to install another battery. would it be possible to run two 5v fans off a single 9v battery? (from the perspective of an electronics n00b, it seems like it should be better, since i'd be drawing 10v instead of 12v, but i'm sure that logic is fatally flawed somewhere.)

    sorry if this has been asked before, but i did use the search feature, and did not find the answer.

    If the circuit is run correctly, you can run 2 5v fans off of 1 9v battery. The only problem with cutting holes in those vents is light getting into your helmet. If light gets in your helmet, it will be a lot easier to see though your visor, which is not cool off you ask me. I plan on running about 4 fans in my helmet when everything is said and done. I sweat more than the average person, so air movement will be very important.

    Fyi most are about 7.5 ish volts. 6 cells .. the good lith ones are 9.

    just getting more and more into electronics lately. i bought two of these microphones to use in an external audio system:

    https://www.adafruit.com/products/1063

    got it all wired up, with a pair of earplug-style headphones (part of the problem is that if i speak too loudly, it echoes in my helmet and really hurts my ears) and managed to get it working, but the sound quality is just awful and scratchy. i've tried reducing the gain, reducing the voltage, adding bigger capacitors, adding resistors, and a couple other things. even with the sound quieter, it is still scratchy. i tried different electret microphones but got the same results. any suggestions? am i just going to have to use a separate amp?

    also, if anyone else is looking for a similar solution, i got one of these, too:

    UPDATE: on a lark, i put resistors between the capacitor and the headphone jack (i had been doing it between the battery pack and the mics previously... like a n00b) and that seems to have cleaned up the sound quite a bit! now it's just a little too quiet. weakest resistors i had on hand were 270 ohms, so i'm going to try out a few different strengths.

    Here's one for anyone.... If I were to build a recess for the visor to go into, then lay electroluminescent lights (string like) down, running it around the visor, would that illuminate the clear visor, especially if it has a honeycomb tint on it, like the MC's????

    Yes, that should work. There are numerous energy swords here using similar solutions. I would look through a few of those. Lighting the visor is a two-way street. While it may look cool on the outside, it will also hinder your vision and light up your face. That is something you may be willing to accept or not, but it does need to factor into your planning.
