OK, holidays are done - back to work on this. Been working on the board layout for the full sized version and that's been tricky. Lots of jumper wires! Almost done though. Haven't put it on the proto board yet. Decided I wanted to do the write-up on the micro board just to get one thing off...

Thanks Jeff. It helps a lot that all you guys know the real specific and resources on this stuff. I've been grinding away at the circuit board design and just today said "uncle" on trying to get it to fit on a 3" x 4". It's looking more like a 3.5" x 4.5". But hey, only partial defeat right...

Got a few things done on this. Worked out the power issues with the added LEDs in the bar display. Added 5 transistors and 10 resistors. Worked out the logic gates for the longer sequence and got it to work with the same number of chips. Just 3 more resistors added. Have the parts...

Oh man, I just got the first one on the breadboard. It's a mess but it works. That's a more interesting sequence so I'll see how much more it would take to do it. The first one works pretty well with the 4 added logic chips. It's a 7 step sequence which works pretty well since at most you...

You know, I'm not really sure either way now. Spent some time in the gallery looking around and just couldn't find anything with a clear shot of the display. None of the close-ups showed the lights on. How about that Star Wars display going on in LA right now? Do they have a Fett suit on...

I like that sequence there better than the one I did for mine. Yeah, that's pretty much the easiest way to do it is with the alternating of the displays. Good news, I drew up the logic chart for the "Rafal Works Sequence" (RWS) and it's not bad with gates. Not bad at all. Works out to an...

Great Stuff! That helps a lot. I can really work with that. So it looks like the sequence goes at about 1/2 second and the off cycle is almost twice that. I'd have to go with twice since it's a lot easier. Excellent catch on the display style. I've been looking around for the ones with...

Mike, that would be great if you have the original sequence! I'm going to order some extra logic chips just to play with.

Thanks guys. Hopefully when it's all packaged up, this stuff will be useful to others. Yeah Mike, the resistors are needed for sure. I learned my lesson as a kid tearing apart calculators and stuff. That's what got me thinking about the micro displays for the costume. How many resistors...

Well, I got the micro version done. Had some bumps along the way but the final working article sure looks cool in the little guy's costume. At least mocked up as it is now. I still need to get a lens (anyone know where to get one?) and the actual mounting done but the tiny display is fun...

Update: Got all the parts in the mail and the circuit on the breadboard AND the transparency for the circuit board (micro display model) but just need to get some things for the developing and etching. This circuit will be a lot like the TK409 version but In looking through some photos of the...

**re-post after I got an error**

Ha! Yeah, now you have like 2 of them right? I cannibalized a tiny key chain light for the rangefinder which worked out pretty well. Well, I'm going to doing something or another at least for the costume I'm working on and will share whatever comes of it here. The TK409 video will be the...

I'm considering making up a chest display and wanted to run it by the group before going off in the wrong direction. The main thing is that I need a smaller one for my kid's costume so I kind of have to do it myself. I came across these really tiny displays that look just about the right size...

Oh yeah, forgot to mention: hiatus is over. Ha! That was short...
