Sorry for the late reply! I honestly wouldn't even know where to begin on a project of that scope. I would look for a forum about homebuilt aircraft or maybe contact the people at Aircraft Spruce.
Just a surplus DC motor. I would however recommend using one of the newer inexpensive brushless motors.
This is freaking awesome!

What you want is a single 5s (5 cell) battery. A 5s battery will be rated at 18.5V. You would not be able to balance charge two individual 3s and 2s packs as single battery.
The only methods I know of to obtain a desired thickness are to either add more layers or sandwich something between layers to form a core. Cores are often foam sheet or even balsa wood.
How you redesign it will depend on the how much space all of that will take up. It's a pretty big helmet so it might fit as is if the equipment is on the small side.
You cannot use a NiCad charger to charge Lithium batteries. Lithium batteries are very particular about charging rates and cell balancing so you need a charger specifically designed to charge Lithium batteries. The closest LiPo battery you can get is a 5S, which is rated at 18.5V.
I used a free program called Fritzing. It's really easy to use.Sorry for the late reply!
I should resist light rain if it's well sealed/painted. It's pretty strong but you couldn't throw it around any more than a cast resin helmet. If dropped on the ground you probably wouldn't hurt it too much but you would definitely damage the rangefinder.

Outstanding! I have a Taig lathe and this is just what I need as I've been thinking about making a ball turner.

I can't see any reason why that wouldn't work.
Yes, I think that would work. So are you molding an entirely new piece or are you adding a carbon layer to the wood trim piece?
Freaking fantastic! Been following on Instagram and I was hoping you would do a full write up here. Well done sir!

Fixing Holes in Dry Wall - the Perfect Patch Method
Great tips- thanks! Getting new drywall to blend in is something I've struggled with on several occasions.
The best way to do that is by making a matrix mold (sometimes called a mother mold.) This involves building up a layer of silicone on each half of the rifle and then this is supported by a fiberglass jacket. Molds of this type can cost hundreds of dollars (or more, depending on size.) You would have a really difficult time making a straight fiberglass mold for that. Have a look at the Punished Props video of a matrix mold here- https://www.youtube.com/watch?v=bjwvak9XjcU&index=3&list=PL6q0fd3ileWJxqvMYIkA8Yd1FoPPe897r

Cool! The nice thing about welding up a metal one is that you can use the saw to cut the metal tubing. :)
The base plate is bolted to the saw where the original blade foot was attached.
Cool- let me know how it goes!
Happy to help! If you have any questions when you get into it just let me know!

Nice! Great write up and explanation. I imagine with a bit of modification this could also be used with an XMEGA Xprotolab.

No need to apologize to me! :)
Thanks! It's worked really well for me so far. If you ever have any questions or need help just let me know.
Thanks so much! I really hope someone can put this to use and make a nice ring. :)
Thanks! If you ever need help with a project just let me know!
Most of those super cheap replacement packs are just that- super cheap. They usually use pretty poor quality cells in those packs. If I was going to rebuild my packs with NiCD cells then I'd use good quality Sanyo cells or pay the money for a good quality pack.Milwaukee and Bosch make wonderful tools and I own several tools from both manufacturers. If I was going to buy a new Lithium drill I'd go Milwaukee for sure- their new drills are really nice. You can have my Bosch worm drive saw when you can pry it out of my cold dead hands. :)
Thanks- glad you like it!
Thanks! Yep, having a stand for it makes it so much more useful and it's really easy to remove it should I ever need to take the saw to the work.
Extremely well. I've cut through 1" thick plate and 2" round bar stock no problem.
None of the batteries I used were rated under the factory battery pack voltage for each drill so not sure what you mean by that.Using a hacksaw blade is definitely better for opening seam welded battery packs than a cutoff wheel- learned that after the first one I converted! The cutoff wheels have a tendency to melt the plastic. I'll update it to show the saw I used on subsequent packs.
Of course there is more involved than just voltage- internal resistance, discharge rates, proper charging procedures, etc. The reality is that any battery of specific voltage and discharge capacity can power a specific motor of a power tool. Safety is a concern when you don't use a battery properly with regard to its chemistry and design specification.Many of the early Lithium power tools were probably less properly engineered than this as some manufacturers didn't bother to balance charge battery packs- some of them were series charged so when one cell in the pack went south the entire pack had to be replaced. Not balance charging Lithium multi cell packs is a real no no. Tool engineers are human and they make mistakes too, especially when they are cost constrained or when management w...see more »Of course there is more involved than just voltage- internal resistance, discharge rates, proper charging procedures, etc. The reality is that any battery of specific voltage and discharge capacity can power a specific motor of a power tool.

Not balance charging Lithium multi cell packs is a real no no. Tool engineers are human and they make mistakes too, especially when they are cost constrained or when management won't let them do something the right way. Good, fast, cheap- pick two. Many engineers don't have the luxury of that old adage due to the constraints of mass production. As for time and cost- time wasn't a big factor as this was very quick and easy to do. As for cost all I had to buy were a few connectors and one 4S battery pack- I already owned everything else. I did explore many options for battery replacement and this is what worked best for me. It may not be the end all, be all solution but again- it works well for me. Your mileage may vary depending on how you use your tools and what resources you have available to you.Using these batteries is no different or less safe than flying multi cell RC aircraft. As I stated, if you're not comfortable with the care and handling of multi cell LiPo batteries then don't do it.
Thank you so much! Hopefully I'll have a couple more Stargate projects in the near future. :)
The tags are available from Sparkfun- https://www.sparkfun.com/products/9417They're really neat and surprisingly easy to use.

Cool! If you ever need any help please don't hesitate to ask!
Of course! Any 3 axis controller will work.
The two stick style drills used NiCd batteries but three of my Makita cordless tools that are 15 years old all used NiMH. NiCd perform better in cold weather and typically have a much lower self discharge rate but NiMH have better energy density and like you said no memory effect. They each have their pluses and minuses.I use NiMH cells when I build custom battery packs for my animatronics projects as in that particular application they make more sense to me. Different horses for different courses!I do store my drills with the switch in the center position (my old stick drill doesn't have this) but I never knew that turned it completely off- thanks!
Thinking about it, a ring like this could probably be made from a single piece of 3 mm square stock about 100 mm long. That's just a rough guess but it's probably fairly close.
