Designing and Creating my own Tricorder from Scratch.

Hello to everyone here.
This is my first thread in this forum, I had been here every now and then but I never see myself in a position to actually "make" something physical for I lack many skills require to pull it off.

Somehow, ever since I watch Star Trek 15 years ago, I have always wanted my own Tricorder and for some reason, I have decided to "try" to create it.

At this point in time, I have no knowledge of Resin Casting and only an elementary knowledge of Micro-Controller Programming.

The original wip is here:
Bracercom :: Work in Progress :: Project Tricorder

but I will be posting my progress so far here to share the joy of this creation [let's hope it will be completed ;p]

Just drawing some ideas, thinking about how the top external interface should look like and how the Tricorder should stand.
I am also thinking about placing the battery compartment in the lower part of the Tricorder just so that I’ll have more space for the electronics on top.
This is important to me as I will be using conventional sized electronic components instead of Surface Mounted Components.

Spend sometime drawing out the “line angles” of my Tricorder.
Logically, I should have carried out this step in the computer as the computer is GREAT at drawing straight lines.
However it’s my personal opinion that with my intention to create the perfect Tricorder “figure”, my mind and hand will derive my Tricorder’s final aesthetic combinations that the computer could not, or even if it could come close, there will still be no “heart” in it.

It’s been a long day today...my eyes barely open as I sat in the train that is bringing me home.
Forced myself to draw something along this Tricorder project before I totally doze off, hoping that in the mist of my inability to think, my brain might just be direct enough to show me what I really want.
This is not the final design, as a matter of fact; I am not going to even begin the inner details until I am absolutely certain about the overall shape and proportion [the relative part to every other part of the Tricorder].
I don’t want to think about battery size, I don’t want to think about circuit board spaces, I don’t want to think about a lot of things right now.
All I care about is the overall aesthetic ratio/proportion of my Tricorder; everything else can kiss my ass until I got the shape that I instinctively like.
[P.S: Now that I think back on this phase, I think this is a complete lie.
I am very aware that I only have so much space to play with thickness wise.]

Right at the very beginning, I wanted my Tricorder to be able to stand upright.
The logic is simple, too simple:
Let’s face it, because I will be using conventional electronic components, I don’t really have much room to play with when it comes to “slimness”.
This automatically translates to the fact that my Tricorder’s thickness will probably match those from the Star Trek 1984’s era TNG show.
So...what’s the ****ing point of all those thickness if it can’t even stand upright ?
Hence I proceed to make sure it will stand upright and that the bottom slate should be around 160 degree from close position when opened.
The resulting Dimple from these two intentions lead to a gap right at the bottom intersection that just so happen to allow the hinge to settle in nicely, perfect !
I am also getting increasingly angry at myself when I am planning the panel design of the Tricorder, I am suppose to incorporate only LEDs, but my mind keeps on thinking in terms of actual screens.
I guess in all aspect, blinking LEDs are pretty 1990’s sci-fi era just like blinking bulbs are in the 1970’s.
In today’s world, blinkies like these are simple too “loud” to be fashionable, everything is going discreet and small.
But the contradiction is, the reason I like the Star Trek TNG~Voyager Tricorder is because it IS so ****ing loud and obnoxious, it’s like it’s screaming “LOOK AT ME!!! LOOK AT ME!!!”
Ha ha ha

With the general shape and plane angles in place, I proceed to model the simplified structure in 3D to get it ready for the next step: actual size prototyping test.

I’ve extrapolated the folding planes from the rudimentary 3D model and created a number of basic paper mock up of the device in various sizes to help me gauge the eventual size of this device.



07.jpg

It’s nice to know that they indeed stand upright as I have intended.



08.jpg

As small as I want this device to be, I must reach a compromise between the spaces that the conventional batteries/electronic components requires and how comfortable I am holding it.

09.jpg

Arh, some things look good on the drawing board but sucks in real life.
Three problems surfaced as soon as I start “playing” with the mock ups:

  • The bottom slate is too angled for my hand to “press the buttons” comfortably.
  • The top angled panel is too steep for my eyes using the main screen as the base viewing angle.
  • The current height of the main screen is a dumb idea because I have failed to take the size of conventional hinges into consideration.
 
I too, hope so Kyosti.

Let's hope that this project wouldn't get stuck half way due to lack of knowledge ;p
 
Yes masterjedi322, I love me some Triiiiicorders :)

Just realize my thread had been moved to the "Replica Movie Prop" category.
To prevent unnecessary disappointment, please understand that this Tricorder will not be an exact replica of the show's.

Thus far, I have already demonstrated I will be having my own take on this Tricorder :)

Unto the updates:

I proceed to create another mock up with the required modifications in place.
The top slanted panel now seems more agreeable angle wise to the main view screen.

However, it seems I have brought the other two modifications too far.
The Main view screen is now too lengthy, combined with the bottom slate that expands relative to it and we now have a really ugly/long looking Tricorder.

The bottom slate is now too wide opened; I feel that my fingers are about to slide right off the bottom slate during simulations.



11.jpg

On the very same day, I proceed to modify the ratio again and I am now very pleased with the overall proportion.

With the final proportion in place, I proceed to, once again, create multiple copies of the Tricorder in the now perfect ratio but in different sizes to find out which felt right in my hand [yes again...].
I do have my crazy good friend Khairul with me helping me out with the size testing when we were in Macdonald, he wasn’t shown here because hell, someone have to be taking the photos of this self obsessed ***** ;p
 
Thanks franz bolo & phase pistol :)

Right at the very beginning [if you look at the very first sketch that started this project], I wanted the bottom slate to hold the battery to free the main box for my light pimping pleasure. But now it seems, reality is setting in, now I know why the original creator of the Tricorder set the size of the Tricorder as such.

If I were to take into account the thickness of the eventual device [the paper’s thickness is not a good representation] along with the understanding that the final device will be round off at the edges, there is just no room for these batteries.

I tried playing with the batteries arrangements for the bottom slate...fail.

If I were to put the AAA batteries on the top box, there will be no space for the screen.

A 9V type batteries would do nicely, but with all the lights I will be putting in...I mean I have no idea how many lights I will be putting in yet, but if I may postulate, this 9V battery will probably die in a few minutes, absolutely impractical.

I absolutely refuse to enlarge the size of my Tricorder, I absolutely wouldn’t do it. I think this project is stuck for now...
 
From what I recall, the screen-used pieces used AAA batteries, so you're on the right track.

And with the few Mark IX/X tricorders I've built, it's always been a tight fit in that upper compartment to squeeze in the electronics and the batteries.

Would it be possible to put the batteries on top of whatever you have planned for the screen, and still fit in the available space?

What about considering some of the smaller rechargeable batteries such as ones from the Nano or a larger Ipod? They'd be more than small enough to fit into the space you're considering for the AAAs. You can find these on eBay and other websites for pretty reasonable prices.

Wow...you built you own Tricorders ?
Dude...kowtow to the Master....

As to your question, that's just it, I have no idea as of yet what to put in the Tricorder, God Forbids I might actually make it useful.
So want to have a big empty space for me to explore.

I just hate the fact that I have to deal with the size limitation of the batteries, it's like a 1980's problem and I am facing it.

Phone Batteries are a no go, I heard they require special circuitries to prevent explosions [Explosive phone anyone? in the news every so often, especially in the UK] not to mention the charging mechanism.

I guess I will have to bite the Bullet and Compromise.

I'll check it thanks ! :D
I'm just worrying about the charging mechanism though.

This is going to look awesome. Would button cell batteries be any better? I imagine you could place them around the tricorder, maybe in the bottom flap thingie. We have small watch size transmitters that utilize a 3V CR2477 Panasonic Button Cell. It's just about the biggest button cell batteries around, but it gets the job done. Just thinking out loud, dunno how complicated you're willing to make a battery change out be. Will be looking forward to progress!

Haha, hardly. The handful of trics I've built have all built kits...either from board members or Rodd.com.

Battery technology has come a long way since the TNG-days, so keep looking. I'm sure you'll find something that'll work.

To epilepticsquirl:
Thanks for the heads up :D

Cell Batteries would be ok...but I am thinking along the path of recharging, because I am going to be one of those people that brings his Tricorder everywhere he goes, crazy ? You bet :)

Cell Batteries would not allow me to play with the Tricorder economically because my wallet will have such a big hole in the end from just buying those batteries ;p


To masterjedi322:
Ooo I wish I can order me some of those Roddenberry's props someday...
I would love to play with your finished toys...

To NakedMoleRat:
I'm just wondering how would one go about recharging a J-Type Battery :(
But good suggestion nonetheless, a number of people had been proposing that to me as well.
 
04 September 2010:

Trying not to increase the depth of the Tricorder directly [one of my German friends saw this mock up and ask: “Is this a brick ?”...], I aim to increase the length of the Tricorder just enough to indirectly affect the thickness of the Tricorder, again, more mock ups.

You might be asking how does increasing the length affect the thickness, this is possible due of the slope angle of the bottom slate.

It works; the battery could now be place into the bottom slate with the thickness of the final material taken into account.

13.jpg


I also take this opportunity to get ready for some hinge testing.

As I look back at this device throughout the day more and more, I slowly developed a kind of annoyance yet again with its length...it’s long...too long...looks like the length aesthetics doesn’t appeals my inner mind, arh...the curse of compromising desire with reality...
14.jpg

Also, the hinges effectively create a sort of “space gap” between the two pieces, hate it.





05 September 2010:
Eventually, I came to the acceptance/compromise/surrender that I should make the Tricorder bigger, just a little bit; this will allow the batteries to fit in and still retain the original aesthetics that I’ve desired for this device.

The Playmate Tricorder has provided me with the insight as to how to handle the hinges, holes were cut into the two parts to accommodate the hinges.

This knowledge is incorporated into the new mock up.
15.jpg

One would notice the holes accommodating the hinges might look unnecessary big on the back side, please understand that unlike paper, the final material have enough thickness to upset the closing mechanism if not accounted for.
16.jpg

With the battery compartment space problem fixed, original ratio aesthetics retained as much as possible without sacrificing much in the area of general largeness of the device and with the hinges now snugly in place, I can say that I am now happy again.

And now with the most important technical issues out of the way, time to go back to imagination land! Back to the drawing board !
Onward with more designs to built up this BABY !
Fun Fun Fun !
 
Great project!

As for rechargeable batteries, I've used these guys. NiMH is the way to go if you're (rightly) concerned about the special charging circuit requirements of Li-ion or Li-poly batteries.
 
ipod Nano and Shuffle batteries come with a charger circuit attached to the battery. I assume Touch batteries are similar.
