What I was thinking was if there were a way to smoothly move large chunks of conversation out of a given #channel (with notices given wrt the transplant) that might be useful. Of course if something was actively going on in the recipient (rather than donor) #channel that'd be disruptful.
There's got to be a way to map this (like with tags) a bit better.
polar wraith
Ahh, true. It would be unsettling to have a whole thread pasted into a channel.
dusty citrus
Well in this channel you have an entry at xx:18 minutes and then my splashdown at xx:31 (just now). A folded transplant (have to click on it to expand it) would work fine in this one instance.
polar wraith
Oh yeah, that's a good idea!
dusty citrus
Then also fold the point of origin so it collapses to a single line (so it displays in context).
Maybe mark anything that's ontopic as exempt. Something like that.

@polar wraith it's not so much my idea. WellEngaged had hidden posts (click to read more than one line). It was a webbed conversation space. They may still use it for all I know.

There's no real specific reason to be licensed, but I still like to see people do so. To get on the ham bands (of course) you need a valid callsign. Occasionally, it's a lot of fun.
barren hemlock
@dusty citrus I got licenced to help with disater relief with the southern Baptists. Then it quickly became a hobby. You can look up my qrz page
dusty citrus
That's great! Sounds like you understand what ham radio is. Many are former CB ops and have a very different viewpoint.
Somehow ham radio has to mean something to you when you're 40 years older than you are today. The surrounding society will have changed a lot. I don't think any of us 1970's era licensees really foresaw how the Internet would impact the niche we once held as our own (free international communications on a hobby-only free of charge basis).

SAD FACE. The local radio club newcomer meeting finished 30 minutes ago!!! 😦
dusty citrus
About one in five of our computer club members were hams, in 1989. We met in Burger King (and a few years later, at Papa Gino's nearby) on Wednesday nights at 7:30 pm.
Four of us ended up kayaking a lot together.
People would bring portables and demo software. In 1989 we were organizing group buys for floppy diskette purchase (typical lot was probably 50 diskettes -- a hard disk backup could take that many!)
One of the companies writing backup software found an unexploited feature of floppy disk drives: you could initiate a copy simply by closing the disk drive door (bail handle) without 'pressing a key to continue'.
You could do your 50-disk backup by ear alone, while watching tv. Otherwise you'd have to look for a prompt on the CRT display telling you to insert the next disk and press a key to continue.
This way, you waited for the chug-chug sound to stop; when it did, you popped the old disk out and slid the new one in, closed the door, and it began copying (some more).
vestal phoenix
My only interest in ham radio was watching my brother when we were kids who was trying to get his license. I remember the Hamarlund transmitter and receiver that he would tinker with. They had tubes and looked like they were from a battleship. We did try to string a big dipole antenna in the back yard. And then the CB era came along.
dusty citrus
I still have a Hammarlund receiver. ;) Probably the same one, or similar to what you remember.
vestal phoenix
They were built like a tank.
karmic kite
@dusty citrus isn't that where the unix yes came from?
dusty citrus
No idea. I'd forgotten about 'yes'. It's fun.
Hamarlund has a lot more receiver variants than I was aware of.
The one I have is hot on AM broadcast reception. Incredible -- just hears everything. Not much use even at 20 meters; almost deaf above 15 MHz. Needs to be reworked, I think.
(can hear local CB on 27 MHz and any local hams operating on 10 meters when the band is open)
vestal phoenix
They make great space heaters though.
dusty citrus
I miss them. My DX-60B was 75 watts with a pair of 6146-B's for the final amplifier.
I can smell the radio almost instantly when it is powered on.
The Hammarlund has a plate switch to cut off B+ (250 volts or so) when in standby.
karmic kite
would an SDR be enough to listen in on some amateur channels?
https://www.adafruit.com/product/1497
vestal phoenix
I recall there was a big oil thing to sink the transmission and kept an eye outside for the white trucks which had FCC trying to catch those transmitting without a license.
dusty citrus
Haha. Yeah the oil thing was a paint can with 50 ohm resistors in it (several). The oil cooled the resistors without conducting too much electromagnetic energy. It's called a dummy load.
SDR is fine. Antenna is everything, in radio.
There's a great website that shows you when the bands are open.
karmic kite
The fiancee is developing with lora, been tempted to buy a few SDR's for playing around with that, but if I can also use them for amateur it could be more fun

polar wraith
I don't want to give the impression that money isn't an issue (it always is), but we get "faster" and "better." Generally not "cheaper."
The "faster" pressure is when you take a program management functional spec to leadership and they don't like the engineering time estimates and they say, "what resources would you need to get that done in xx months?"

see what happened is some insulation got stripped off further down since it's a very weak rubbery plastic, I wouldn't be surprised if it actually is rubber, but some got stripped off, on one of the wires where it forks off into two wires each to one speaker

in any case Heat shrink is good for insulation just get the proper diameter
or else won't do the job

One day I walked into a parts store (mostly salvage-oriented) in Denver, Colorado (I was living there for a while). I was astonished at the variety, and realized I'd lived in smaller cities all my life - that there was a bigger world out there I knew little about.

@polar wraith I think I fixed the pulseio stuff
polar wraith
@stuck moth Awesome! I'll try to tinker with that in a bit. I'm testing PWM on CP3.0 for Kattni at the moment.
stuck moth
I mean the PWM stuff 😃
polar wraith
Did you push it to master? I can reflash my boards and re-run the tests before we send the results to LadyAda....
Sorry, @stuck moth , I was distracted and thought you were talking about an earlier problem. Yeah, Kattni's test script uses pulseio, so if we've changed it I should rebuild the images and reflash the boards.
stuck moth
I was thinking of the tone problem
but it likely impacts the pin mapping stuff as well
(it incorrectly thought pins had timers it didn't)
polar wraith
Well that explains quite a bit. 😃
I'll re-test the audio after I get the PWM test done. We've resorted to spreardsheets and shared docs to keep track of things. It can get complicated and it's easy to lose track of where we are.
stuck moth
totally

@stuck moth I just did a pull and didn't see pulseio in the file list. My last pull was yesterday around three. Did you commit the code changes yet?

The change was in the pin file

Ah, ok. Cool. Thank you, sir, I'll re-build and flash. BTW, I checked with the powers that be and it's completely cool for you to come to the Garage for my talk on Adafruit/Circuitpython.

can the pi 3b+ run starbound at 5+ fps?
if so I want one
I still want them to make an intel atom based raspi, same specs, just with x86-64 architecture
it could still run raspbian, as raspbian pixel runs on arm and amd64

Intel has basically killed off their low cost Atom lineup

hey,
would the official pi zero case be fit for carrying a pi zero in my pocket?
on the bottom is a hole exposing the bottom of the gpio pins which might be an issue,(could cover it with red electrical tape to match the rest of the case though)
dusty citrus
it should be fine even open if its not powered, might collect lint and/or coins though so be sure to inpsect it before operation.
sleek urchin
Eh, there is an issue of ESD though
there's a good chance you accidentally touch a pin and zip it in your pocket
I'd suggest putting the pi 0 + its case into an ESD bag
dusty citrus
Sadly the bag the pi zero comes in it just about 1/4 too short to house the official case (just checked) that would have been a great free solution.
karmic light
are you moving it once or daily?
dusty citrus
3/8 would be better
if I knew 3d printing skills I would develop a snap in bottom for the case, that would solve it.
karmic light
do you have a caliper to take measurements?
sleek urchin
I'd suggest just searchign thingiverse for a case
dusty citrus
but then there is the camera slit in the bottom too hmmm maybe not
yea if you could find an alternate bottom to the official case that would be good too
or you could get a reeeeeeely long esd bracelet and chord.....
karmic light
dreamy solstice
I'm saying, if I used electrical tape to cover any holes in the pi zero case, would it be safe to carry the pi in my pocket, in the case
karmic light
imo yes
dusty citrus
yea just electric tape or kapton tape over the pins and the camera port on the bottom should be just fine in your pocket.
dusty citrus
just have to be sure to lintcheck your usb and hdmi ports before use as that can build up unnoticed
dreamy solstice
oh, as I use vnc over usb ether, I'd be covering all the ports except the data micro usb
which would ease the checking process
dusty citrus
some of those little rubber deals would be ideal if you can find them on aliexpress or the like or print some in ninjaflex.
I guess if your advanced you could take the bottom portion and dip in in silicone mold to get a nice silicone mold port blocker... boy I need to get to making, so many ideas!
polar wraith
If anyone is interested, I'm working on a new application for Adafruit tech. Marines currently use ChemLights to mark night-time landing zones for aircraft. I'm building a Feather-based DotStar LZ marker. There are some pros and cons to the idea. Fortunately, I know enough Marines at Camp Lejeune that I can get this tested on the down low. 😃
dusty citrus
if you do perhaps consider a remote kill on it, we used these on the dz many a times as well, or it turns into a drone and flys to the rally point after use... gah I think I got the fever today!
karmic light
Oh man, I can't imagine trying to make something robust enough for mil spec
polar wraith
That's one of the cons. As the Marines say, "there's no such thing as Marine-proof." And, "put three ball bearings in a padded room with some Marines, and in an hour one will be unaccounted for, one will be disassembled, and one will be non-functional." 😃
dusty citrus
yea there is a reason they use chem lights, cheap and fire and forget and no batteries
karmic light
^
polar wraith
That's another of the cons, @dusty citrus !
karmic light
what are potential benefits?
polar wraith
The DotStars will be significantly brighter, which means the pilots can pick out the LZ and orient themselves faster.
dusty citrus
a good compromise would be develop the same chem light with a biodegradable plastic and non-glass eco friendly capsule, then you would save the planet and maybe even get rich at the same time if you get a contract for them. They buy em buy the million.
karmic light
I wonder what shelf life of both are
dusty citrus
to be honest I think any kind of neopixel varient is just too bright for a dz, it for use with nods mainly and not to advertise your presence.
karmic light
If its just for pilots why not try something with IR?
dusty citrus
ir works but again a bit bright and requires batteries that is why they use chemlights, dependable in any weather.
polar wraith
Tracking. The idea is to build a non-mil-spec prototype and have the Marines take a look. They might come back with, "this is a stupid idea, we don't have a problem that needs solved."
karmic light
isn't IR invisible to the naked eye?
polar wraith
That's a good idea, @karmic light

being ex military yea I can say not a great idea and already covered
its not a stupid idea though, no ideas are stupid.

mhmmm

Yeah, that's the problem with all the centralized intelligence fusion products. Bad guys get it and they know where blue force is....
karmic light
encryption is nice but adds significant complexity I would assume
polar wraith
The data communications from the squads are encrypted in the design. It adds some complexity but that can be engineered around.
The infantry Marines really liked the design because they (the ones I talked to) had a number of friendly fire incidents in AFG (including an artillery barrage) because of poor location communication.
karmic light
but is that a technology or organization issue?
polar wraith
Both, actually.
karmic light
I've seen a few times where a perfect system doesn't solve a problem because there was poor ownership or buy-in from stakeholders
polar wraith
I have too. My first step was to see if it would solve problems for the in-the-field warfighter. Now some intel and officers are reviewing. It's an interesting process.
Admittedly, still in "ideation" phase.
karmic light
At least you're thinking eh?
polar wraith
😃 I like to think so. Sometimes Marines are very direct about correcting my misconceptions. I think of that as "clarity."
karmic light
I like to think of it as "refining scope"

I am building a raspberry pi zero w 1.3 usb stick, that I can use a wired or wireless connection(plug it into a battery and wirelessely control it,, or plug it into a pc and control it over usb ethernet) to make a usb console emulator stick
acoustic elk
That might be tricky, from what I'm reading right now it seems as though you'd encounter horrendous lag
We use VNC at work for a hackintosh and for all our little tricks we've never been able to get VNC to be all that responsive, i know it's worlds apart from an rpi but after some googling it seems like people advise against it
What if you used a bluetooth controller and had a separate circuit for transmitting what comes out of the AV pads to a second unit?
dreamy solstice
I use a wired connection so it should be faster
it doesn't lag when I use raspbian on vnc
acoustic elk
fair enough, but doesn't VNC use a Framebuffer Protocol that sends pixel data? Emulating games might be a bit taxing, and require significantly more redraws
dreamy solstice
I'll set the quality and encryption settings down

the AV pad transmitter is still an option, if a little overdesigned and bulky

you would not happen to know the draw of the pi?

karmic light
I would go with max draw of the pi. Which I think is in the region of 2.5A since thats the top end of the power supplies recommended for them?
sleek urchin
then don't forget that depends on how it powers the pi
since I believe you HAVE to power the 5V rail
so you have an 80% efficient boost, then a say 85% efficient buck on the pi itself
karmic light
So max is 15 W by my estimate then
Which is within an order of magnitude of this site https://www.pidramble.com/wiki/benchmarks/power-consumption
Because as soon as you start plugging things into the Pi it will draw more
dreamy solstice
I made pixel art of slave 1:
pearl yoke
Awesome
dusty citrus
The Pi varies a lot, moment by moment, what it will draw. I've watched it on the Charger Doctor (not sure about the r in Charger there, hi hi).
I would count on frequent loads of 250 mA with the Pi 3 (the last upgrade before this newest one). ISRT 250 mA was about right (1A would have alarmed me, and I don't remember seeing that -- I don't even think I saw 300 mA on peak demand).
That's with nothing but the usual connections to the Pi (probably includes HDMI and one keyboard/mouse wireless dongle).
Back of the envelope, I'd assume 125 to 150 mA during active use, average, and see where that gets you on battery life. Double the battery you think you will need (If possible/reasonable).
And then test.
sleek urchin
125 to 150mA is closer to idle
But the big key is the Pi is VERY voltage sensitive
so even if you have a 2.1A supply, if it starts dipping, you'll get the brownout detect on screen
I got tired of that, ended up getting a big 50W Aukey power brick =p
protip: don't get a hefty power brick and think for a second you'll get clean power out of it. adds to much noise on my headphone amp, gotta use a dedicated supply for it
haven't had a brownout warning since I started using it though!
dusty citrus
I had a shortwave portable radio that wasn't really sincere about its power supply input jack, and preferred batteries (it was mostly unlistenable using a wall-wart, almost all of which are switching supplies).
The lightning bolt symbol appeared onscreen with the Pi, when I'd move a servo motor with the Pi (and Adafruit Seesaw providing the pulse train to the servo).
http://adafru.it/169
I think a 4700 uF BFC helped with that (may've cured it). PSU was more than adequately rated, too.
cursive pike
@dusty citrus I’m looking at just the Pi running headless, nothing on usb. Using wifi, however. Wifi config will be the interesting thing. My thought is to have it create an ad hoc network that the ipad can connect to, then ssh/mosh in.
The fallback is a PiTop. But I figure the ipad + keyboard is a perfectly fine ssh terminal.
dusty citrus
@cursive pike For power supplies, I like to determine the magnitude of the problem of current, by blowing fuses too small for the job (if that's a reasonable approach in a given system) to try to estimate real-world conditions, prior to regular deployment.
You can get very low rated fuses, so I'd think in the range of 125 mA would be simple to acquire (a fuse, for).
My guess is 350 mA would not blow (would be reliable for a long time) but below that, might blow.
With my (two-way transceiver human-voice) radios I'm willing to blow a fuse every six weeks as the cost of derating them just a bit, rather than risking damage from overcurrent.
I have a piece of test equipment that wants a 2A fuse for 120 VAC power input. It is missing a fuseholder cap (threaded, iirc).
I went inside and wrapped a single strand of copper wire from a lamp cord, across the fuseholder's terminals.
I don't know at what current it'd blow at, but I've blown such 'fuses' before; it's a fairly modest amount of current.
Still, liquid copper doesn't sound attractive to me, so I hope it doesn't blow before I can get around to doing the proper repair. ;)

I’m not even talking about them

$6k on a gaming PC is ridiculous
$2k? Yeah, that's more common. especially when you pay for Intel and Nvidia parts
for a high end gaming PC
(not including monitors, since there's some stupid expensive ones there people buy)
covert spire
Although, I’m annoyed with more new mobo having lights on them
Even AMD builds are now hitting $2k
sleek urchin
heh, well, there's a lot of overpriced GPUs there
RAM is twice as much as it should be
covert spire
Still Nvidia in GPU of course
sleek urchin
and they're finally not a pure-budget brand
covert spire
Like I said about memory
sleek urchin
but then, it's also what people consider essential..
covert spire
Exactly
sleek urchin
there's too many who rave about Intel's 18 core i7, and talk like 64GB is some sort of minimum
covert spire
Well, also mobo is now supporting AMd more like it should
sleek urchin
well, it's finally a valid platform
Bulldozer was pretty bad in comparison to everything else when it came out in 2012
a budget choice, but that's about it
covert spire
Well, it seems rather silly to drop huge coinage on Intel with that kind of proc power & not have ran to back it
sleek urchin
it's a wonderful processor when it turns winter here
covert spire
Now i3 can compute what most people need
sleek urchin
yup
covert spire
Hahahahahahaha!
sleek urchin
although really, 4c/8t is about minimum for a mainstream build I'd say
Especially given AMD has good, inexpensive 4c/8t offerings now
covert spire
I seen some prebuilts still using 2c
sleek urchin
which is nonsense
sleek urchin
the Ryzen 5 2400G looks quite tempting for a mainstream type of build
I'd say paired with 16GB of RAM. because 8GB doesn't last long even if all you use is chrome
if I land a reasonable job out of town, I'm setting my mum up with my current desktop
to get her off of the cheapo laptop she's still using
covert spire
I’m not having too much trouble with 8gb right now
sleek urchin
8GB is a minimum, I'd say
covert spire
Although, I would like to get 2nd stick for it
Well, I opted to buy a bike instead
Yes, my bike actually cost same as a ram stick
sleek urchin
when I eventually do build a good PC... I'm going for at least 32GB.. But that's also because I'd like to be able to run a bunch of VMs
covert spire
I’d want that, but for CAD, gaming, video editing, etc
sleek urchin
heh, oh yes, for the rest of it too
Specifically drooling over something like the new Ryzen 2700x...
covert spire
Although, I would like to one day build a OP computer for once
sleek urchin
I'd say a Vega 56 paired with that, but those haven't been available for MSRP in.. forever
covert spire
And tag it “Supercomputer of Tomorrow!”
I was looking at i9 build
But, that would be up in $15k
sleek urchin
kind of ridiculous =p
covert spire
Exactly!
sleek urchin
Intel scrambled to release that 18 core part (a rebadged Xeon) after AMD announced their 16 core part..
and it's still <1/2 the price
covert spire
Then like 64gb ram
sleek urchin
where as you can get the 16 core threadripper for $1000, even plenty of sales too. motherboards are $350 to 600 depending on featureset
sleek urchin
heh, really, at that point, why aren't you offloading to a server?
sleek urchin
if money were no object.. I'd put together a proper virtualization network, with a minimum 10GbE network
karmic kite
I mean personally virtuallization kills my memory... 16 is barely enough
covert spire
Back to graphics demand
karmic kite
it'd be nice if cryptocurrency fad could stop
covert spire
Not going to happen anytime soon
sleek urchin
yup.. even if someone is introducing Ethereum ASICs
all those other alt coins still demand GPUs..
covert spire
I think someone is
sleek urchin
Yeah, someone is making Ethereum ASICs
covert spire
I know Barnacules mentioned once about ASICs
sleek urchin
still too many alt coins for GPU demand
covert spire
But, I think he jumped on bandwagon to use server for it
sleek urchin
Sadly, cryptocurrencies are this massive waste of resources
they don't even act as cryptocurrencies, because you can't use them to buy stuff
covert spire
Name a currency that isn’t
sleek urchin
they're all speculative investments
covert spire
Name any investment that isn’t
sleek urchin
at least with something like a US dollar, it is easily exchangable for something else
The fluctation in value and the slow processing times for transactions really kill eg. bitcoin
as being a viable currency
covert spire
That is what caused the fad, Bitcoin becoming accepted
All transactions takes time, just people see the resources it takes with cryptocurrency
sleek urchin
all transactions take time, yes, but the question is whether it's 2 seconds, or 2 hours, or more
covert spire
Depends on the bank
sleek urchin
bank transfers are their own, horrible things
but you don't use bank transfers in day to day life to buy things
maybe something huge, like a house
covert spire
Banks have to accept transfers out
To account for to the account you purchased from
Even the card sliders use bank transfer
The only method to not use bank is cash
sleek urchin
I don't know where you're from, but using a debit machine does not take 2 hours to confirm a transaction
covert spire
If it’s same bank as you use, yes, if it’s owned by any other bank, it will take longer time
Yes it’s fast
And I have dealt with bank cards that didn’t have it’s own ATM
karmic kite
At least its regulated away from consumer grade cards

Picked up an oscilloscope for a hundred bux at the ham flea market today (in Southington CT).
This one is similar:

Mine's the PDS5022S, slightly older. Functions well on audio. No other testing done.

I’m stuck in Denver, Colorado after having to escape Cancun (3 AM I was at the airport) due to oversold tickets on almost every flight to the US. I had 3 Roll overs back in Cancun and I got 4 Roll overs here in Denver. I’m definitely gonna miss school, coming back into my hometown at 1:30 PM to 2:00 PM. Things have been TENSE.
Wish me luck, #3-#7 and there’s 9 seats open.

I wonder with less ads from social media and google on cryptocurrency if the fad will decline...

Stapelton is a decent airport. Denver's wonderful. Go take a quick bus ride on Colfax! /loves_Denver
Better yet: go to Boulder. You will not regret it. Can bus it public transport.
