I got a Unisonic 21 untested and it turned out to need some work. Time to figure out what's wrong.
This is a fairly anticlimactic video. It ended up "working" in the end but I didn't really do anything. I did notice it did actually very faintly turn on in the beginning, I still don't know why it got brighter over time.
Yes I could buy the capacitors, but it doesn't make sense to place an order for just this device. Although I may do that in the future with an online order if I piggy back it onto something else.
About the back filming surface, after a test video I decided to record a complete video using the underside of my ESD mat. Here is the test video: • mattest The blue reflects a lot of light onto the subject and into the camera during macro shots. A darker mat would give a noticeably better image quality. But the black is too dark. It didn't work well for this video. I will be going back to the blue side until I get something else that works better.

The white "ghosting mark" /IS/ a problem. It should be nice and shiny, not white. The display lost some of it's vacuum and the getter material that was deposited onto the glass was used up when the air started entering. The round thingy is a transformer. It's not faulty, you have the Negative 35-ish volts you need and the AC filament drive.

@TechTangents 5 лет назад

You made me go look up the part number for the display, and it is looking like that may be the problem based on the white mark being black on NOS parts: www.ebay.com/itm/VINTAGE-FUTABA-13-BT-94Z-8H-VACUUM-FLUORESCENT-DISPLAY-NOS/264066687238?hash=item3d7b99e106:g:AZkAAOSwnfRcAXwY:rk:1:pf:0 I was basing this off an experience with a Casio CQ-1 I was sent. It uses a VFD that was sealed with a white glue substances that looked just like this does. I got a bunch of comments telling me the VFD was bad in that when it wasn't because I repaired it by replacing a blown transistor and the display is brilliant on that device now. So from that I learned a white mark may not be a bad VFD which is now a lesson I unlearn with this one. Unfortunately, that VFD is still about the same price as the caps and therefore the NIB example for me. So I will still not be repairing this one.

@semifavorableuncircle6952 5 лет назад

Yep, VFD clearly is gassy, needs to be replaced. 35V looks healthy for a display like that. 8Ohm ESR isnt good but would not cause much trouble yet.

@AnonyDave 5 лет назад

I was about to point out the same thing. Beat me to it, good job!

@johnbonham7515 5 лет назад

David Richmond You're right, it's a gassy vfd, the shading towards one of the ends is more evident in dc filament vfd tubes, the emissivity decreases as it gets farther from filament ground.

@zaprodk 5 лет назад

@@johnbonham7515 In this case i think the shading is a coincidence, other than DC filament. The small round TDK transformer offers proper AC drive which is what's used here. The shading might be a mix of a gassy VFD + bad multiplex timing.

@@guycrew728 My intention is to now find a very deep dark blue. It should really be an ESD mat so I can work with out worrying about damaging parts(and snide comments). A medium grey would work as well. Most ESD mats are too lightly colored though so it's a challenge.

@deathventure 5 лет назад

A general rule of thumb for cap replacements with me is if it's blown/bulged, I'm replacing it with a higher voltage rating. If they're old, I will replace with like or higher voltage depending on what I have. 50volt ratings aren't unusual actually, even with caps down to 1uF. Whenever I get from Mouser, I usually do a variety order with a max of 20 bucks including shipping. I'll get what I need, plus a general variety of other value components to throw in my parts bin. If I need 10uf caps, I'll get them plus a few extra, and I'll throw in 100uF, a couple 1000uF etc. It helps to build a small stock if you find yourself repairing things like that often.

@eduardoavila646 5 лет назад

Its funny how i aways see these prestine looking capacitors all failed and broken in other's people hardware, in videos, etc. But my old pcchips board with literally 90% of the caps badly deformed rusted and even leaking sometimes, still actually decently working (after you clean the ram slots with alcohol because capacitor fluid might be getting in there sometimes). I gave this board 3 years ago to a friend who supposedly would (eventually) recap it, but from what i know he didnt recap it yet, lol

@TechTangents 5 лет назад

I made a slider out of a server rail. That is a real slide with fixed focus on the camera leading to the calculator. At some point soon-ish I'm going to be doing a filming setup video covering my new camera and the new microphone I got that I used for the first time in this video(a Marantz MPM-3000). And it's called a Dolly Zoom, so you were close!

@CattoRayTube 5 лет назад

@@TechTangents Oh wow, nice idea for the DIY slider! I'll have to keep an eye out for some stable rails for my own video projects haha Looking forward to the new gear vid :) Oh, and thanks for the correct name too haha

@TechTangents 5 лет назад

After having made it, I don't recommend making a slider out of a server rail. It rotates way too much because it's really only designed to be strong in one axis. I had to add a flywheel and pulley system to make it even close to stable and it still isn't great. I'll cover why it's not ideal in that gear video.

It is, and it's another one of those things that just really shows how cheap this was. Most of my Unisonic calculators feel kinda cheap but they were really early. Some time I should look into the company's history and see what their deal is. They may have been trying to make very affordable devices when the market was still new and trying to cut costs anyway they could.

I like to fix my own stuff , it’s kind of a hobby .There’s a huge scrap yard near my shop that has tons of electric boards laying around , whenever any of my appliances or tech gadgets break i go there and always find whatever i want . I’ve found dozens of capacitors , resistors , diodes and even mosfets for my welding machines . I became friends with the owner ,I pick up whatever i want and the he even invites me to sit down for a cup of coffee and doesn’t charge me anything , when u said 10$ for capacitors i felt pretty lucky .

@manfredmurer9508 5 лет назад

It's indeed the display that's gone. The getter-spot has turned white, that means that air got into it. This way it can't work properly and it will even worsen as more air gets into it. Also the heated cathode will burn out rather soon in the presence of air.

I looked at calculator.org and these came out in the mid-seventies, I got my first Radio Shack calculator in 1977 and it had the just introduced memory function. So, the dumbing down of the calculator started just about the time they were becoming affordable.I also looked up the pric of the Bowmar 9018 (the Boiwmar Brain) which was considered one of the first mainstream pocket calculators. The price for that in 1971 money was $240.

When making a list of components to order in the future, make sure you also write down what they're for. Otherwise after a year, when you remember you had seven order lists in five different locations on your hard drive, you're like "what the hell were these for?" I also tend to lose my repair notes so sometimes I write a post-it note of the symptoms and possible defects and fixes I've discovered, as well as a mention if I've connected mains to the logic chips, and leave the note inside the case for future me. Or maybe even someone else who wants to fix it when I've lost my marbles and I'm being treated someplace soft.

@michaelsworkshop9031 5 лет назад

Come on - pull the trigger and just complete the repair! Between the time spent troubleshooting this device and filming and editing, you're already invested way beyond the value of this gadget (30x?). Just order the caps and solder them in - that's the fast part left to do. Maybe slot that part order in alongside others next time you're putting an order in with DigiKey or Mouser or whoever, so that the shipping gets subsidized by that new order - we can wait for the video. Also, I wouldn't trust the ancient new in box one as necessarily being any more reliable than this one, unless the seller is showing pics of a fabulously working screen, etc. Best wishes.

related: www.halfbakedmaker.org/blog/a4821-reveng-1 Calculator is 8 digits? I wonder if they just transplanted/used the same calculator device/logic from their other 8-digit calculators, and put that next to the BlackJack logic. The display shimmering could be from the calculator logic/output colliding with the blackjack output until the clear/reset causes the BJ to disable that. While some websites list the earlier handheld "Unisonic 21" as having 12 digits of precision, I've only found pictures showing the calculator using 8. I wonder if they later updated the logic after introducing calculators models that actually do have the needed precision.

Hello. I've just spent about 30 minutes of my life watching an old cheap calculator-with-a-game repair video. The device was disassembled, the restorer hopped from one potential cause to the other until he finally fired his ESR-meter after 23 minutes, so that could have been another recap video. Then he decided 5 caps were 1 dollar too expensive et reassembled the poor thing with its old caps. In the meantime, either with usage or because of the iron solder heat, the caps restored themselves just enough for a faint display. 30 minutes of fiddling and no actual repair...
