The Endgame Tricorder TR-990 XSL [07032007 0118]

This is the Tricorder from the last episode of Star Trek:Voyager titled "Endgame" set 25 years into the future. The design is such that it has a larger viewscreen compared to the other Tricorders and has faster blinking rate for the LEDs. Which I presume is to show the audience that its scanning functions has become faster. The Tricorder's controls are very different as well as you can see it on the lower flap, apart from it having a second viewscreen.

I think there are two versions of the MK OSX Tricorder as the one used by (future) Admiral Janeway does not have an external scanner like the one used by EMH. So, if I wanted the EMH's Medical version, I would have to scratch built the extra bit.

I got this from eBay after a very lucky turn in bidding, thanks to nexus. The seller had included the electronics for the kit, which was too good to let go. I must have it at any cost. Eventually, after paying a small fortune and tax, it was in my hands. The kit is an actual Roddenberry product which I have yearned to get it for quite some time. Apart from the Mk VII and MkX Tricorders, this is a must have prop.

 

This is the image taken from eBay and everything is there, just like the photo. So, no instruction sheet, is not the seller's fault

 

First Impression

Opening the box, the contents are as follows:

1. 3-piece resin consisting of the upper primary body, the lower primary body and the flap

2. Sticker sheet

3. Roddenberry Certificate of Authencity

4. Screws and hinges, tranparent sheet for the main screen and lower covers for the Tricorder

5. A small piece of paper on whom to contact if you want the kit professionally done

6. The electronics, which is actually, not part of the kit

 

The box contained the three resin pieces of the Mk OSX, the sticker sheet, the screws and hinges, and lastly, the electronics

The sticker sheet is nice, and I would need to make a black masking sheet after having learnt my lesson with the Playmates Tricorder

As far as I know, there is no ready-made product the Tricorder can be made from. It is built from scratch, just like the other Tricorders (except for the 29th Century which is made from an Oregon Scientific Clock)

Looking through the contents, I discovered that there are no instruction sheets for both the kit and the electronics. This means I have to make my own conclusions. But the standard procedure of using magnetic switches and connecting the hinges to provide power to the lower flap still applies. After looking at the kit, the main problem is the power source. There are a lot of LEDs in the electronics, which means it would need a lot of current. And looking at the space available (assuming I have put in the electronics) I think I only have about 5mm to play with. The only battery I could think of would be those flat J-type (approx. 48 x 36 x 92mm) batteries which gives out 6 volts. I have tested the circuit with 6 volts and it is quite dim. Maybe its because the batteries I had on had were already spent.

At first, I have thought of getting those flat lithium-polymer batteries but to make up for the voltage, I would have to get two of them. Combined together, their thickness would not be able to fir into the cavity. And even if I can get them in, I would have to design a charger as well. Since Lipo cells tend to create fire, I decided not to venture into this path. I just hope that when I have a new set of batteries, the LEDs would be much brighter.

 

This is the video of the electronics test with a very weak set of batteries

More Details

The casting for the kit is very clean and it is very light. And it is a delight to hold them.

This is the view of the tricorder and is fully opened. Unlike other Tricorders of the same genre, this one opens out flat

There is a change in the casting as the ribbed details are moulded in instead of being a separate piece

This is the upper part of the primary body and there is a hole at the bottom which is to access to the Tricorder's electronics and battery. You can seal it with the screws given in the kit.

The front part of the Tricorder which does not have a lot of blinking lights

But it is compensated with a lot of details instead but I am so tempted to put some lights in.....

If you look closely, you can cover each cavity with a screw. They have already moulded in the metal screw threads into the kit

The Tricorder is quite thin when folded, its thickness is about 25mm

When it is fully opened, it measured 138mm and this is quite small

Each kit comes with a Roddenberry Hologram. I have no idea why

 

Test Fitting

OK, so I got bored. This project is not to be worked on until I get the Phaser Rifle out of the way. But I just like the blinkng lights..........

The electronics fit right into the main screen without much problems but I would only know once I built the screen

There is, however, a fitting problem at the lower flap as I could not get the board in unless I cut out the small area of the circuit board

Looking at the electronics, many have used SMT (surface mount) to save space and also power. But for this kit, they have used quite a fair bit of ICs

After much digging around at the ASAP site, I discovered that the circuits actually belongs to Gerry and throughout the discussion, his circuit board cannot fit into Roddenberry's but his very own, which, was also beautiful. The actual electronics, were taken from COB kits (which I incidentally have when I was in Singapore in '03) and also those hard to find Made in Chine three-led trinkets (which I got some in Sibu, Sarawak but left them at the Hotel) which blinks very fast.
