Lisp Badge LE
- hwestiii 3y agoI love this guy. I ran across him trying to self teach about embedded electronics and his site is one of the best I’ve found both for interesting projects and good instructional examples.
- lioeters 3y agoI love his projects too. He's also the creator of uLisp. (If it weren't clear from the article.) http://www.ulisp.com/ http://www.ulisp.com/
- smegsicle 3y agoi love the full keyboard- any time someone says they wouldn't benefit from learning vi bindings because they 'spend more time thinking than typing' i hand them one of these
- herewulf 3y agoVi bindings come surprisingly in handy while typing in the terminal on my smartphone even.
- capableweb 3y agoYeah, surprised me as well when I was trying different ways of editing text and sometimes code via touch keyboard, vim bindings was the easiest way by far.
- tyingq 3y agoFirst thing I looked for was dedicated parentheses keys, was not disappointed.
- otikik 3y agoProbably should have put them on the center of the keyboard, though :)
- msk-lywenn 3y agoOr in the back or top, like gamepad triggers/bumpers!
- Horffupolde 3y agoShould have a spare set.
- scns 3y agohttps://neo-layout.org/ https://neo-layout.org/ has em under your strongest fingers, after holding down a modkey.

- gleenn 3y agoThis is a really cool project. I wish I was better at doing electronics construction, wish I could just buy one too. 40 hours of life on a coin battery is pretty impressive.
- staypufd 3y agoYou can buy one. The link is at the bottom of the article.
- anonzzzies 3y agoLooks like that’s only the pcb though? Or am I clicking the wrong link?
- wslh 3y agoI am also curious about having an assembled one.
- dudus 3y ago"The connection to www.technoblogy.com is not secure You are seeing this warning because this site does not support HTTPS. Learn more" It's 2023 people. How can you justify no https on a technology blog?
- worthless-trash 3y agoEasy, the owner doesn't care about the data served from their source gets MITM'ed.
- incanus77 3y agoThis guy’s projects are a fave of mine, especially the tiny computers like this and the audio projects. And the tiny photography is great!
- LispSporks22 3y agoI’ve used uLisp via the serial port. In that mode of provides a cool structured Lisp editor (easily navigate sexps). I wonder if the display one here does the same thing.
- zubairq 3y agoThis is really awesome. Kind of like a programmable calculator but super powerful that you can take anywhere!
- matheusmoreira 3y agoThis is way too cool.
- captn3m0 3y agoI’d love if old Blackberry shells became standard casing for such projects. Perfect keyboard, good display size.
- eimrine 3y agoBlackberry-compatible motherboard with appropriate keys and nothing more may be done relatively easy, but where to get drivers for the display and the sensor joystick?
- mkreis 3y ago40 hours with a coin battery is impressive, but I think it is a bad decision in terms of environmental friendliness.
- herewulf 3y agoIndeed. Are there rechargeable coin cells?
- anonzzzies 3y agoYes, look for LIR2032 batteries.
- guenthert 3y ago"The Lisp Badge LE draws only 6mA from its CR2032 button cell, and so should have a life of about 40 hours" I suppose that's 6mA when the CPU (MCU here) is active. In idle mode that ought to be much lower (the low power monochrome display, not eInk, draws only 30µA as stated separately). Does uLisp support idle mode? Uh, apparently not automatically, but requires the user to call a SLEEP function ...
- anonzzzies 3y agoWish someone would build this in a casing etc : especially the 40 hour our on a coin cell. 3d printed should work, but I don’t have time and would just like to buy it complete.
- pjmlp 3y agoQuite cool, specially how the keyboard and special symbols being taken care of.
- dannyobrien 3y agoulisp is great - I have it running on a little neopixel matrix I use to flag when I'm on video: https://github.com/dannyob/signpost https://github.com/dannyob/signpost I'm ashamed of how much power that sucks down compared to this badge though!
- randomcarbloke 3y agoDammit I haven't finished populating the last lisp badge.
- kagevf 3y agoPopulating?
- privong 3y ago@randomcarbloke probably means installing/soldering the components onto the board. E.g., https://www.digikey.com/en/maker/blogs/2021/how-to-populate-a-pcb https://www.digikey.com/en/maker/blogs/2021/how-to-populate-...
- randomcarbloke 3y agoExactly, a very generous chap on here sent me a spare PCB for the lisp badge.
- ngcc_hk 3y agoMy part list is still on and the display is in my part bin so far. Hope this one may fair better. Realky want one.
- onemoresoop 3y agoI'd totally buy a fully assembled one but I wonder how much it would go for.
- freilanzer 3y agoSame.
- thsksbd 3y agoFor the kids its be great
- roydivision 3y agoArg, I'd love one of these, but my project backlog has backlogs. As others have commented, I'd buy a fully assembled unit.
- thsksbd 3y agoI'd love to buy this for my 8 year old - this week I taught her how to check her homework on elisp. The idea is to familiarize her with lisp syntax a bit to prime her for programing in the future. I was between calc (RPN) or lisp (elisp) for their simple syntax. The way I see it LISP's REPL loop is simple enough to teach a kid. And I may be right: after teaching her to verify a two argument operation she got a three argument question. She did: (+ 12 43 67) :)
- rnk 3y agoYou can order one through a link on that site, can it be only $23? That's what pcbway.com says. I need a more turnkey approach, someone tell me what to do to get a working board I can just plug in an use. If you ask for "assembly" then it was adding almost $100.
- thsksbd 3y agoThats just the board, I think
- rnk 3y agobecause of the display and low power use, I'd pay somewhere between 75 and $100 for one of them in a plastic case with some easy power supply/connection like maybe a usb plug-in port? It's such a cool display and keyboard. Another cool thing (that I'd pay for!) is to attach that to a rasberry pi.
- jhvkjhk 3y agoMay I ask what's the point of attaching a standalone computer to a raspberry pi?
- rnk 3y agoThe display and keyboard would be fun to have where I interact with the ras pi directly; I don't need to attach another sbc to a ras pi of course; but where is there such a neat display and keyboard that I could get for a pi? I have several rasp pi, I wish they had an inexpensive display and keyboard like this one. I could use it for commands on the shell. But it's mostly to play with. That's just a great form factor! In such a situation, I was thinking you could use the cpu to communicate with the ras pi somehow, ssh into it? It's just a neat form factor with that compact keyboard and display, using such little power. By itself it's fun too, but I'm not going to do much assembly work, not doing anything that takes soldering. I'm just terrible at that kind of stuff. If I could buy a complete little computer like that, with some kind of storage maybe, it would be neat. I didn't understand how much effort it would take to get an actual working system that I could type on like the original poster.
- timonoko 3y agoExcessive. Interlisp TTY editor requires only one line display.
- benj111 3y agoTTY as in paper? It's not quite 1 line, you have a history, you can display an arbitrary amount of lines at once.
