VT-69 Handheld Terminal

It's a dumb terminal. You can connect a Raspberry Pi to it.

It's a badge that's a dumb terminal. It doesn't actually *do* anything, because dumb terminals don't actually do anything. It's just a keyboard and a screen. It'll teach you the difference between a DB-25 and a DE-9.


Hardware Specs / Function

It's a dumb terminal. It doesn't do anything. You can wear it around your neck. It's got a keyboard and a screen. The prototype will have a DB-25 connector if it kills me.

WHAT: This is a dumb terminal. That means it doesn't compute anything. This is not a computer, it is effectively a teletype you can put in your pocket. To use this device, you must connect it to a computer. Again, this hardware does nothing, because it is a dumb terminal.

WHY: doesn't this do anything? Because it's a dumb terminal you can fit in your pocket You can connect it to other computers! It will work as a serial console for 2018's Defcon badge. Again, this is a dumb terminal, with a keyboard, that will fit in your pocket. Because this should exist. Oh yeah, you might be able to put a Raspberry Pi in it, so that it can become a computer.

WHAT: up! We're three cool guys looking for other cool guys who want to hang out in our party mansion! Nothing Sexual. Dudes in good shape encouraged, but if you're fat, we expect you to find humor in the little things. Again, nothing sexual.

TWITTER: Yeah go here or something

  • Unit Cost And Economics

    Right now, I have the schematic and design done enough that I can get some quotes and go through the actual cost engineering of the VT-69. The TL;DR, is that this would cost more than you would pay.

  • System Design, Previous Work

    Benchoff04/18/2019 at 17:21 0 comments

    The core feature of the Dumb Badge is to provide an 80x24 character display, with a keyboard, and a serial port. The first requirement of a high-resolution display is the hardest requirement, but there are many cell phone screens that will give you 800x480 pixel resolution, conveniently the same width as the display in a DEC VT100. The display is therefore the hardest part of this project, and demands specific engineering decisions. The purpose of this project log is to discuss these engineering decisions, while covering earlier work done by others.

  • A Design Study

    Benchoff03/14/2019 at 20:48 1 comment

    I am designing the Dumb Badge with the idea that is a product, not a single one-off project. Being a product demands some work must go into the design, both the design language of the enclosure, but also the typefaces and logotype of the screenprinting and packaging. Basically, I need to decide on a font or two. It's also time to start designing the enclosure, which means I need to imagine what a product made in the alternative history of 1991 would look like.

  • The Prototype Keyboard

    Benchoff03/02/2019 at 20:05 0 comments

    I'm buying a thousand silicone keyboards, months before I have finalized hardware. I need a way to test the samples of these keyboards, and the easiest way is to turn them into a USB keyboard.

    The TL;DR is that everything is on the Gits

  • On the subject of keyboards

    Benchoff02/10/2019 at 18:51 3 comments

    The dumb badge requires a keyboard, and I'm doing this with a silicone keyboard like you'd find in a remote control or a ZX Spectrum. That's the easiest and cheapest way to put 100 buttons on something. But what is the layout going to look like? It's time for a review of existing terminal keyboards, how I made my keyboard, and a neat testing apparatus.

So I know this is going to be mainly a thing given out at conferences and such. But, as someone who is really interested in this project and would like to get one of these, yet cannot travel out to these conferences, would you be willing to sell some on Tindie?

  Are you sure? yes | no

Benchoff wrote 04/09/2019 at 21:30 point

The plan is to do the launch at cons, and that'll be testing, looking at the future features needed, and improving what I've done until that point.

After that, I'll move into larger-scale production, and they'll be on Tindie.

Why not open/closing similar laptop and meybe proportion of screen , look at zx88 cambridge 

If You think about working version please add a big utf-8 charset. Nerd Fonts for powerline for example and add some programaly keys (remember many languages need altgr for working)

  Are you sure? yes | no

Building tools for tools, for tools.  Right up my alley.
