2026-04-21 05:55:31 <lisbeths    > i may be switching from lisp back to forth again
2026-04-21 05:56:03 <lisbeths    > but im not going to be coding in moore's style im going to be coding it "the bad way"
2026-04-21 06:36:22 <nmz         > KipIngram: That's really good, I wish I could compartmentalize, I cannot, and so I can say to those people, they are incredibly ignorant and should be shamed for having such crappy opinions.
2026-04-21 06:36:55 <nmz         > its a harmful opinion
2026-04-21 06:37:22 <nmz         > lisbeths: good
2026-04-21 06:37:47 <nmz         > drop forth, use factor
2026-04-21 06:52:04 <lisbeths    > I think I can implement the majority of factor's features in forth
2026-04-21 06:53:19 <lisbeths    > I think I'm gonna be using basforth for high level coding and sectorforth for embedded
2026-04-21 06:53:42 <lisbeths    > and then I am going to implement lisp in two short lines of forth
2026-04-21 06:54:14 <lisbeths    > I think im one of the youngest forth users at 31
2026-04-21 07:34:54 <nmz         > probably the last human one
2026-04-21 07:51:52 <veltas      > What's harmful is all this crap about mental health and the therapy industry that gets people hooked and makes them even more annoying than they were before
2026-04-21 07:53:22 <veltas      > If you're anxious or whatever go for a walk, have a drink.  If you go to a therapist or take drugs then the pseudo scientists thank you for your contributions but you'll need to stop talking to me when you won't shut up about mental health talk
2026-04-21 08:16:43 <nmz         > 2 months ago a research paper came out which indicated that thinking negative thoughts reinforces neural pathways
2026-04-21 08:16:52 <nmz         > the more you think about it, the more you reinforce it
2026-04-21 09:07:59 <lisbeths    > as someone who has completed all of my credits for an associates in psychology, that research has been around since the 80s and is part of cognitive behavioral therapy
2026-04-21 09:39:51 <veltas      > nmz: That's really the issue I think, is that there's a big risk you "try to get help" and end up thinking even more about it and spiraling
2026-04-21 09:41:31 <veltas      > lisbeths: I think CBT and DBT are the only things that seem to be good for people who have issues, and those I would say can be replaced by just being less 'negative' and thinking less about bad things, changing your scenery, etc
2026-04-21 09:42:15 <veltas      > Whatever I say it's not going to stop people going to therapists, but I hope at least to make people sceptical and with a mindset to just be open minded but get the hell out if it's just making you worse
2026-04-21 09:43:02 <veltas      > I mean the drugs work too, but it's a dangerous chemical game you're playing
2026-04-21 09:49:38 <lisbeths    > ive been dreaming of this calculator for years
2026-04-21 09:49:52 <lisbeths    > in my dream I go into the dollar store and this calculator exists
2026-04-21 09:50:04 <lisbeths    > i first designed it when I was awake
2026-04-21 09:50:38 <lisbeths    > i was fascinated by the one dollar jot scientific calculators at the dollar store and opened one up to see what was inside
2026-04-21 09:52:11 <lisbeths    > there is a small 7 segment display. there is a single battery. there is a motherboard with only a single chip. fthere is a piece of paper with conductive ink on it. finally there is a rubber membrane that connects the circuit on the conductive ink paper. all this is housed in a plastic housing with four screws
2026-04-21 09:52:50 <lisbeths    > i began to try to cheapen the design and at first I realized the screws could be replaced by lego style connectors that snapped in place
2026-04-21 09:53:29 <lisbeths    > but then I started to think "what if this was general purpose instead of just a scientific calculator"
2026-04-21 09:54:41 <lisbeths    > so I realized the 7 segment display could be made to display the alphabet. the chip could run forth. the keypad could be remapped to work like an old dumbphone where 0-9 type the alphabet
2026-04-21 09:55:40 <lisbeths    > ive tried to talk to some chinese manufacturers about this design but they did not seem interested. yet I think its possible for a general purpose computer calculator to be under three dollars at the dollar store
2026-04-21 10:05:52 <veltas      > Surely manufacturing lego style connectors to the correct precisions is more expensive than screws?
2026-04-21 10:06:13 <veltas      > I don't know anything about mechanical engineering but it seems like that i sso
2026-04-21 10:06:26 <veltas      > I know Lego is expensive to make to their standard
2026-04-21 10:16:53 <lisbeths    > it wouldnt have to be lego it would just have to snap together
2026-04-21 10:17:13 <lisbeths    > also I think it should not come with a battery included to save money
2026-04-21 10:18:14 <lisbeths    > I also think instead of rubber buttons your finger could complete the circuit for the conductive ink
2026-04-21 10:24:07 <veltas      > I'd prefer screws so it's easier to maintain, but if cost is the main goal then I guess it will be disposable
2026-04-21 10:27:23 <veltas      > Have you considered looking at receipt machines?
2026-04-21 10:28:46 <veltas      > There's a big market for them and they don't seem to get cheaper than like 10 GBP, so $3 might be difficult
2026-04-21 11:26:03 <MrMobius    > lisbeths: would this be a thing to make money or a hobby project?
2026-04-21 11:27:56 <tpbsd       > MrMobius, get your buck.boost working yet ?
2026-04-21 12:02:48 <lisbeths    > it would be something to make money
2026-04-21 12:03:16 <lisbeths    > the jot scientific calculators already made money. but they could be made to be general purpose computers
2026-04-21 12:10:15 <veltas      > Interested in updates if you do anything with this
2026-04-21 12:17:36 <MrMobius    > lisbeths: neat idea. I got into forth because of calculators which is my main interest. are you thinking about something like a graphing calculator or the old scientific programmables?
2026-04-21 12:18:28 <MrMobius    > tpbsd: not yet. couldnt figure out why the TPS63000 wouldnt start up. switched to TPS631000 which is newer. almost done with the board
2026-04-21 12:18:42 <MrMobius    > didnt you order one not long ago?
2026-04-21 12:21:25 <tpbsd       > MrMobius, yes I ordered the TPS63000DRCT
2026-04-21 12:21:42 <tpbsd       > MrMobius, I havent tried it yet
2026-04-21 12:23:01 <MrMobius    > hopefully it works better for you than it did for me! I suspect the QFN might be to blame. the new one is a tiny 2.1mm x 1.2mm SOT so I can at least tell if it's soldered correctly
2026-04-21 12:27:15 <tpbsd       > MrMobius, I'll try it soon, I just need to set up my microscope and soldering gear
2026-04-21 12:27:17 <MrMobius    > new board is USBC -> FT232 -> TPS631000 -> STM32G0B0 -> 4x STM32G041 and BMA530 accelerometer. also, new pic32cm which seems to be an AVR replacement
2026-04-21 12:27:53 <MrMobius    > right. I cant imagine doing it without a microscope now that I tried it. qfn will be deadbug?
2026-04-21 12:27:55 <tpbsd       > nice, Ive been meaning to try an accelerometer for years
2026-04-21 12:28:14 <tpbsd       > yeah, deadbug here always for prototypes
2026-04-21 12:29:09 <MrMobius    > nice
2026-04-21 12:29:51 <MrMobius    > the TPS63000 has a big ground pad on the bottom. I suspect that might be part of why mine doesnt work right so curious to see how it works deadbugged
2026-04-21 12:31:52 <tpbsd       > me too, Im doing an article on five different regulator chips, and the TPS63000 will be the first
2026-04-21 12:32:47 <tpbsd       > it will be in my new 'distributed documentation' format and Fossil DCVS is required to view the docs,wiki, flowcharts and code etc
2026-04-21 12:37:01 <MrMobius    > that's a great idea
2026-04-21 12:37:12 <tpbsd       > plus schematics etc
2026-04-21 12:37:15 <tpbsd       > thanks!
2026-04-21 12:37:30 <MrMobius    > the power system is the hardest part imo. I'm really hoping ill just find one setup and use that for everything
2026-04-21 12:38:09 <tpbsd       > youll only need to download the regulators.fossil file from my doc site when it's available (Ill post the url to it when it's there)
2026-04-21 12:39:03 <tpbsd       > MrMobius, Ive spent 50 years doing power designs and repair, it's a field I know very well, it's been one of my pet interests
2026-04-21 12:40:22 <tpbsd       > MrMobius, plus, if you want to send me any additions you make to  regulators.fossil, you only need to generate the patch (really simple) and email it to me :)
2026-04-21 12:40:58 <MrMobius    > nice
2026-04-21 12:42:52 <MrMobius    > what are the other regulators?
2026-04-21 12:45:31 <tpbsd       > LMV431BIM3/TR, TPS613221ADBVT, TLV62569DBVR, MP2359DJ-LF-Z-MS
2026-04-21 12:46:12 <tpbsd       > I just looked in the LCSC products and chose a few at random
2026-04-21 12:46:36 <tpbsd       > these are all SOT-23 so really easy to use
2026-04-21 13:11:30 <MrMobius    > planning on measuring quiescent current too?
2026-04-21 13:15:04 <tpbsd       > no, I wasnt, I'm not comparing which one is best as Ive never used a buck or boost chip before, I just want to see if they work and how easy/hard it is to get them going, how fussy they are
2026-04-21 13:15:33 <tpbsd       > how easy they are to use, what general features they have
2026-04-21 13:15:59 <tpbsd       > besides, I dont have a decent wide range psu powermeter yet
2026-04-21 13:17:15 <tpbsd       > Im still thinking about a wide dynamic range psu/powermeter  based on the TI patent for one
2026-04-21 13:18:44 <tpbsd       > MrMobius, basically it consists of two maybe three PWM psus, eash with a specific range, ie  nA, mA, A
2026-04-21 13:19:47 <tpbsd       > and it adds the number of pulses of each one together to get the overall power usage
2026-04-21 13:20:17 <MrMobius    > right. I think the newer launchpads have that. hoping to use it to measure current
2026-04-21 13:20:22 <MrMobius    > dunno how low it goes
2026-04-21 13:20:34 <tpbsd       > I still havent worked out how to combine them in a logical way
2026-04-21 13:20:52 <tpbsd       > yeah, TI use them on some of their products
2026-04-21 13:21:43 <tpbsd       > I imagine that when one reaches it's max output, it switches to the next higher one etc
2026-04-21 13:22:32 <tpbsd       > and when one reaches it's minimum output, it enables the next smaller one
