Sandbagger's Iron-Man builds - Now in STEEL

sandbagger · Feb 8, 2016

Thanks guys. I'm feeding all these ideas to my electronics guy. I won't pretend to understand all of it.

Update:

Had a bit of a solder session and tidied up all the batteries and wiring. I'm just using AAA and AA for now, but will eventually change to LiPo once I advance it all a bit.

Eye lights and video glasses are all one unit now. Easy in, easy out.

And a quick motivational shot with all the lights going.

I just love this thread...GM

Breathtaking dude. :thumbsup That standing assembly looks sooooooo good. Just wow.

Just when I think ..."Nah, this can't get any cooler."...Well, you get the idea. AWESOME!

Would actually be worth sticking to AA/AAA for travel (seeing as most airlines now bitch about LiPo batteries in checked luggage)

Loving this progress. Keep up the good work mate :cheers

It seems the rule for airline travel with Lithium-based batteries are getting tighter all the time.

I recently built new versions of of my bracers using mostly 3D-printed parts and at the same time went from a 5V microcontroller to a 3.3V version. This means i can technically now use a 4.1V-3.7V LiPo battery and I will eventually make that an option (as soon as I get the right connectors - turns out the ones I had were not the right ones even though they worked). For now, I kept the old design of using two CR2032 batteries. I can easily buy replacements anywhere I go and I don't have to worry about airline rules.

As far as Sandbagger's suit is concerned, I would imagine the relative weight gains from going to LiPo or Lithium Ion batteries would be negligible. Then again, when you are building something heavy, maybe you still want to keep it as light as possible. In terms of personal safety in a metal suit that might be difficult to take off in an emergency, I think I would feel safer with NiMH or alkaline batteries.

Sorry if this has been asked earlier in the thread, but how are you going to see out? I saw you had the video goggles mounted in the helmet, but where is the external camera going to be?

I'm not planning on flying with it and if I do, I will insist on either wearing it on board or being with it in the cargo hold... I'm not letting this thing out of my sight when it comes to baggage handlers and their rotten reputation.

As it takes nearly 25 minutes to get into this suit and nearly as long to get out of it, I will be making the battery packs removable so if anything goes wrong, they can be quickly ejected from the suit.

I will be sorting that out tomorrow night. Watch this space.

I'm at the stage where I have no money to devote to this mate. So I do what I can with what I've got and a small trickle of money now and then...

I had to chuckle... it seems like all of us, except Tony Stark, has this problem

Amazing work and dedication so far.

Spring loaded the flight control flaps behind the foot. Now they hug the back of my heel and move with it as my foot pivots instead of just flapping around.

POR-15 total rust treatment of the inside of the suit. About three hours of work this afternoon with marine wash, metal prep and the final coat with sun and heat gun drying in between.

This man is a dentist, so we can't show you his face..... Mr electronics specialist playing in Iron Man's research and development wing, AKA - candyland.

The field of view and the picture quality on this tiny camera is phenomenal!

Size comparison of the camera with the video glasses.

Have you decided where the camera is going yet mate?

Yes I have.

I thought the R&D center was a IN A CAVE!! WITH A BOX OF SCRAPS!

Hi m8, loving the build. Could you tell me what brand of video glasses you are using?

China basically - Alibaba/Aliexpress for the video goggles and DX.COM for the cameras

Tonight I drilled the hole for the camera and hot glued it into position to test it. I've got to fiddle with the camera angle and depth to get it exact. The external hole is 10mm but the rim of the camera is 1mm thick and can be painted to match the shell of the faceplate, reducing it's footprint to 8mm diameter. With a clean-up, paint and the lights on it should be pretty hard for anyone to see it.

I did some practice walking in the house and performed some simple tasks in the kitchen, wearing the glasses and camera. It's obviously a little different from normal vision and will take practice and some getting used to, but it is FAR better than the standard narrow slots under the eyes as seen in other suits. No more crashing into things and wondering if I'm on the last stair or not. I am one happy little Mr Stark.

I then designed another all-in-one bracket so the camera, video glasses, eye lights and battery/command unit for the VG's will all pull out together by undoing just two screws. Tomorrow I'll fabricate and install it.
