Another never finished electronics project: my electronic typewriter that would make a very nice retro style terminal but isn't one

Background story: I wanted to park my car at a certain small parking lot that's usually pretty full. I was lucky: There was a free spot. Or so it seemed. As I drove up to it I saw there was something lying in the middle of the free spot. Looked like somebody got rid of some scrap there. I got out and honestly I wanted to put the stuff to the back of the parking spot under the tree that was there. If somebody decided not to bring their scrap to the right facility for free for some reason that doesn't make me responsible to pick it up and bring it there, I thought. But when I saw that it was an almost new looking electronic typewriter, I quickly decided to take it with me instead. It was a Triumph Adler Gabriele PFS. As I read somewhere it came out in the late 2000s or early 2010s. So not as vintage as the name typewriter may sound. But definitely some old piece of tech that is obsolete now but has a nice character and conveys a feeling from a certain time. That and the fact that I've never had or even used one made me add it to my collection of retro tech (that I've never before called collection because it doesn't really deserve that name).

Back at home I examined and tested it and I would have cleaned it, but there was nothing to clean. The case of the internal transformer was cracked and the outer case had a deep scratch at the corner where the transformer is. Everything was working fine except for the 2.8" diskette drive. The rubber band had long been degraded. But the bigger problem was that the main motor didn't do anything else than heating up very quickly. I couldn't find a replacement easily and still couldn't find a good replacement when I searched more thoroughly later. So I've replaced the drive with an emulator so I could use SD cards instead of diskettes. That not only has the advantage of working right now but also of using a medium that is more reliable being handled by my clumsy self and available easily. New 2.8 " diskettes would cost more than SD cards and couldn't hold nearly as many and long documents.

Before the drive emulator worked I had to work a bit with the developer of its firmware. I was lucky that I had a logic analyser and that the project was actively maintained by a developer who cared for adding support for my typewriter. The interface for that model of Mitsumi QuickDisk drive was already supported before. But the reverse engineered parameters, especially the timing was just not exact enough for my Gabriele.

Well, that's the state the machine is in right now. I can use it, I can save documents to SD card, I can't read the original diskettes and I can't read the documents on a PC or create documents for the typewriter on a PC without writing software for it first. I'm not using it for anything. The best thing I could come up with on what I could/would want to do with it is to add an interface that allows me to use it as a text printer. It has a printball with all important characters (no ASCII line art though, sadly) and maybe completely switch out its software to give the machine a new purpose. The easiest way for me would probably be to ignore all the electronics that are already inside and add a microcontroller that handles the LCD, print head and communication with the outside. I still wouldn't have any use for that though. So additionally I would turn it into a serial or telnet or SSH terminal, maybe all three. That would be more fun. Vintage look, vintage keyboard, vintage feel overall, a display that is subpar because it's old technology but still good enough to do its job, and the ability to print text on paper. Yeah, that would be fun. But I still wouldn't really have a use for it. I have a laptop that can do that job better and the keyboard of the typewriter doesn't have as many keys as I'd want it to have.

So, I'm not going to do it, or anything else with it. Maybe some day. Or none. Got any better/additional idea what I could do with it?

What I post here

Entry created on 2021-06-08 Authors: steeph (376) Categories: Personal (13) Languages used: en (257) edit

I don't know. I just kinda wanna have said this once.

I'm not creating a carefully outlined collection of blog posts worth reading here. I just make or edit an entry when I feel like it. About what I feel like writing about at that moment. I decided that I don't want to let thoughts like the realisation that what I'm writing won't might not be interesting to anybody or the apprehension that an unfinished, not proof read or evidently meaningless entry won't be of any use to anybody stop me from making an entry. This is my space, I decide what I put here and I refuse to impose a standard on it. I may treat this like my diary with entries that will only be of value to me (or future me) or share something that I actually find worth sharing or I might post something that I would never have thought I'd post here, before I did so.

I guess one way of saying what I want to say is: I know this is not the most interesting blog on the web. So what?

draft0 just became a multi-author blog.

This entry is a reply to or continuation of the entry 'Hello World, my name's struki'.

When I started this blog on log.steeph.de and the underlying website generator, SBWG, it was intended solely as my private web site/web log that I could use as an outlet for more or less personal or relevant posts without the espiration of creating something complete that I should be proud of.

But as it happens, struki obtained knowledge of the site and plans had quickly been changed to make this a multi-author blog and moved to draft0.de. We had tried something similar before. But the reasons that made me take the old blog offline eventually are not present this time. So, provided we continue publishing entries, this should last for a while.

Welcome, struki! 👋🎉🥳

Trolls - Winning Feels Like Losing

Entry created on 2021-06-03 Authors: steeph (376) Categories: Communication (3) Emotions (1) Personal (13) Story (5) Trolls (2) Useless Memories (5) Languages used: en (257) edit

Sometimes I realise late that I'm interacting with a troll in an online forum, on Reddit or on a mailing list. For the type of trolls who delibertely try to confuse and seem to be sincere on the surface while following the goal of inducing frustration or otherwise spreading negativity, I have to give to them, that makes them good at what they are doing. But none the less it makes me feel bad all the more. Not much for wasting my time, but for being honest to them while they know they aren't honest to me. I feel betrayed when I conversed more than one or two messages long with a troll.

And that's what happened to me again today. I gave them the benefit of the doubt even after I realised that they had been given many chances to see they made a (simply and definitely provable) honest little mistake but didn't take a single of them, had not responded to a single direct question while constructing a kindly phrased little unrelated allegation out of nothing instead. After a few more messages with no progress I had enough and started to type my response to inform them that I'm not able (or willing? see next paragraph) to view their motivations as sincere. I felt a bit mad and that feeling became stronger the more I re-read what they had posted. But I wanted to make my final response complete and correct, so it seemed necessary to invest this emotion. And I did intend to make this my last post in the thread. I wanted them and maybe others who were still following the thread to know that I'm fooled no longer by this troll. I'm glad I realised that that was still feeding the troll and refuted what I was trying to convey before I submitted my post. I did the right thing by not continuing to give them a fulfilment of receiving any attention at all. But now this is an unclosed chapter in my mind. I'll call it unclosed memory so that I have a term (and category tag) in case I want to refer to similar experiences on this blog in the future. I guess that's the reason I'm making this entry. I did it, dear reader! I got out when I finally did realise what was going on.

I'm imposing this label "troll" on this person and even have a drawer in my mind for people who acted similarly in other threads that I've read in the past. But the thing is - and that's probably a banale thing to say for anybody who has done some thinking about online trolls before - I couldn't prove that they are, even given a perfect defitinion with clear criteria. I don't know their intentions. I want to feel a little bit proud for giving them the benefit of the doubt for longer than apparently any other participant in the thread. I believe that it is ususally the right thing to do to not assume malicious intentions in somebody's actions even after you had the realisation that that is a possibility. I want to be the person who assumes kindness or lack of knowledge before assuming bad intentions. But I'm still often very naive (mostly the kind of naive that makes me tell strangers my weaknesses, like being naive), even though that has changed a bit in some situations. But I always assumed I'm being made fun of or that people try to make me look like a fool rather soon. I think I can hardly know with sufficiant certainty whether that's the case in situations like the one described above. So I will feel unsure whether I made the right decision. (Not that I suspect it matters for this person's life in this case. But in principle.) Among the reasonable things to do with experiences like this I've marked "tell somebody about it" and "discard the memories of it by not trying to bring it up again unless it severly impacts my life" as good options. I've dine the former by writing this here. I'll go on to do the latter now.

Project Idea And A Little Story: High Power PC Cooled Completely Passively With Heat Pipes And A Large Surface Aluminium Case And My First Online Post Ever

Entry created on 2021-06-02 Authors: steeph (376) Categories: Bulletin Boards (2) CPU Cooler (2) CPUs (5) Case Modding (11) Computer (78) Cooling (2) DIY (17) Heatsinks (2) Personal (13) Projects (41) Useless Memories (5) Languages used: en (257) Topics: Projects → Case Modding (9) Projects → Ideas (8) edit

Here is another project idea that I'll probably never realise. It's not really an ingenious idea or a new concept. But there is a reason for why I can't forget about it.

In the very early 2000s, when I started to tinker with PC cases and also made my first steps in web communities, I thought about how I could reduce the noise my computers made without running chips at dangurously hight temperatures or forgoing performance. I've read about heat pipes in some case modding community. And I thought why not take it to the extreme to move heat quickly not just to a larger heat sink than the CPU sockets could safely hold (Motherboards didn't have cooler brackets back then.) but to a heat sink or several heat sinks that cover the majority of the case's surface. When the first commercial CPU coolers with heat pipes came on the market, targetet at computer tinkerers, but still nobody in the community seemed to attempt to make a case with a huge heat sink on the outside of the wall to cool even a 2 GHz Pentium 4 with its 75 Watts TDP passively, I decided to register in a small case modding web forum and present my idea to see what might be wrong with the concept. I was actually younger 20 years ago than I am now and I had never before tried to get myself out there in such a way. I thought it was a rather good idea. But I wasn't sure how much surface and aluminium mass I needed and wether it was realistic to cool a powerful CPU passively that way. Trying to cool a Pentium 4 only passively sounds like a stupid idea after all.

So I created a post on said web forum that I've never read before, presented my idea and asked for opinions. I got a few answers and everybody seemed to think it was a stupid idea. One respondant didn't seem to get my idea but still seemed to think it was stupid. One person seemed rather friendly in comparison and asked if I could explain the idea in more detail. I felt bullied by the negative answers, I felt mocked by being inline quoted (which I don't think I had seen before) and I felt that my ideas were generally worthless since I wasn't one of those hobbyistic experts that actually know stuff and are able to answer questions asked in a web forum. So rather than explaining my idea in more detail as requested, I searched for a way to delete my post, didn't find one and asked in the same thread how I could remove it.

I didn't find the post when i searched for it a few years ago. Like most small web forums it has probably gone offline with nothing or almost nothing in a web archive. But with the experiece that I have today I suspect that I didn't explain my idea very well and the other forum members didn't realise that I was a very insecure child. I also realised many years later that it wasn't a bad idea. I even saw a computer case that implemented the same idea being sold at some point. I don't know if many people bought this. But at least somebody other than me seemed to think it made sense and could even be commercialised. This redeemed my idea in my mind and I started to think about making such a case again. But I don't have the need for high-power CPUs and didn't want to invest money into another project that I wouldn't ever finish once the initial exitement would be over by buying huge heat sinks and heat pipes. So I've added it to that huge imaginary list with projects that I like to would have done but likely wouldn't finish and conclude my decades long considerations and my decision to conclude them by writing this entry.

Done.
