Did you finished this one? i have it lying around :facepalm doing nothing...
So can I hire you to build the electronics for my suit? Lol very impressive work sir.
Shaun, you also used Sintra (hardfoam PVC) as material right?
Im building the MK43 in this material. Really quick building.
Does the Fibreglas resin stick well???
How bad is it? Maybe your mix was to hot... to much hardner
I am planning to coat the outside just with a little resin, to get les soft surface.
The inside will be with fibreglassed and resin.
What would you suggest?
Great build so far! I do have a question about the electronics as well, that seems to be the hardest part for me personally. How much would you say you spend on the electronics in the helmet?
It seemed bad enough that I nearly binned the lot. Some parts are salvageable, but others need to be redone from scratch. Luckily, the back, thighs and cod look repairable.
I'd probably make a few test pieces first. The parts that suffered the most were the compound curves which had a lot of scoring on the back. the resin soaked in, then started to eat the styrene. Perhaps a layer of pva could stop this?
I'm going to sand back all the damaged areas, fill with bondo, and then make moulds of everything so I can make the final suit as light as possible. I also want to make each piece as pretty as I can so that they're not completely outclassed by your neck brace
Glad to see you're back on the build. I'm going to need some inspiration during the long winter nights filled with sanding and filing ahead of me.
Hi IronMeg
The biggest cost for my helmet electronics were the video goggles - I got them second hand, but they were still £130.
The 3D printed servo mechanism was £70, but there are plenty of DIY hinges that work just as well for a much lower cost.
The rest of the electronics including the arduino came in for less than £80, but I did bulk buy a lot of the smaller components for use in future projects.
This is easily the most complicated bit of electronics I've done, but it wasn't too difficult. Have a look at http://www.therpf.com/f78/iron-man-...cs-tutorial-170853/?highlight=helmet+tutorial , which has several really detailed (but not too scary) circuit designs for the servo and eye controls. If you're not sure what a component does, take the time to either read up on it, or just watch some Youtube videos. Relays, transistors, resistors and regulators are all fairly common in most electronics projects, and understanding roughly what they can and can't do will give you loads of ideas on how to design your systems.
I'd say the best thing you can start with is the Arduino. There are lots of other microcontrollers that can do the same job, but the vast library of example projects for the Arduino really make things easy. You'll have LEDs fading and flashing in no time.
Hope you have fun with it!
