@late fulcrum I'm surprised the often-forgotten fifth basic force of the universe didn't take effect here: a 10mm socket must always move away from the rest of a socket set and from the owner.

Having all those 10mm sockets in one spot might've caused a tear in the space-time continuum.

late fulcrum Nov 8, 2019, 6:56 PM

#

10mm sockets often bind together, while repelling other size sockets. When you finally find one, you'll often find another 2-3 along with it.

grave crest Nov 8, 2019, 7:00 PM

#

....I've never observed more than one 10mm socket in close proximity to another. Yet, you have photographic evidence of this rare event.

@late fulcrum @grave crest If I order a niche MCU board, it will of course come with the odd USB mini B socket; and no cable I can locate will have a the right plug. I hypothesize a USB mini B repulsive force that separates matching mini B plugs from sockets.

Apparently "High vis markings with UV additive glow under UV light" makes it easier to track them down. You could try adding that to your mini-usb cables. 😆

I'm pretty sure I read somewhere authoritative that the USB mini B is sensitive to UV, and reacts with protective camouflage.

I'm not sure how you're imagining "setting" them in a PCB. The diameter doesn't look terribly consistent, but perhaps you could press them into plated ~.7mm vias before other board assembly steps? I don't know what specific drill diameters are offered at the usual board houses, checked oshpark and all I see right away are min/max, not a list of available diameters.

#

ah there's a tolerance figure, ±0.0635mm max

late fulcrum Nov 9, 2019, 5:05 PM

#

I'd probably use a CNC mechanism to pick up each one, dip it in glue, and place it in position. The hard part is picking them up one at a time and orienting them pointy side down, shiny side up.

If somebody does this I would love to see the results!

idle iron Nov 9, 2019, 6:59 PM

#

I was just thinking of soldering them on, I'm very skilled with a soldering iron, but i was thinking it would be hard to roll a tiny bit around 3 edges. The glue Idea sounds easiest.

#

Im pretty sure diamonds can handle the heat the only issue would be heating and cooling too fast could cause shattering

dusty citrus Nov 9, 2019, 7:24 PM

#

How hard is it to get a new battery for a UPS? I haven't opened it yet to check, yet due to health. I am getting better.

#

Soldering diamonds is going to be very hard. They are a rock (mineral). Depending on the quality the heat will crack them after a while. Diamonds are formed from extreme heat and pressure, so you most likely will not be getting it hot enough. Cutting it will require a laser. They are one of the hardest materials known to man, but can be crushed with a hammer. Currently relying on what my geologist dad has told me.

grave crest Nov 9, 2019, 8:50 PM

#

@dusty citrus Amazon/BHPhoto/Newegg/etc is usually the most direct way for a new UPS battery. Price compare, and be aware that some places don't necessarily sell OEM parts. You might get something rated a little less than what you had.

Every model of UPS is slightly different, but most consumer UPS units make it relatively easy to open and replace the battery. Most of the time it's a slide out panel that just clips in -- no screws.

That's because all UPS units ship disconnected -- before you can use them, typically you have to connect one of the battery leads.

As always, take note of which lead goes to which polarity terminal, always work on them unpowered and unplugged, and if there's any leakage of the battery, take extreme caution.

After replacement I'd suggest doing a test with something unimportant that has minor load -- and doing so in a safe area with a fire extinguisher handy.

If you don't feel comfortable with any part of this, it's totally ok. Sometimes the price of a replacement battery is more expensive than a black friday sale for a whole new unit of equal or greater capacity. As much as I discourage disposable electronics, that's an option.

Does a bullet fired from a gun cause a shockwave?

#

You know that sort of feeling you get in your chest when you’re around a REALLY loud sound?

#

Is that a shockwave?

#

Yes

#

It is a concussive force.

#

It is a small controlled explosion.

#

Interesting

#

I can tell you more but in pm. Some people are a bit touchy on this topic

#

@grave crest thank you

fickle slate Nov 9, 2019, 9:19 PM

#

Are really loud sounds shockwaves though?

#

Like if you are at a concert and you feel the bass, would it really be a shockwave or just like the sound waves causing to vibrate lol

dusty citrus Nov 9, 2019, 9:23 PM

#

I mean, sound is mechanical energy

#

If it’s strong enough, it’ll move your insides, and make that really uncomfortable feeling

#

Aren’t those like mini-shockwaves?

hardy rock Nov 9, 2019, 9:36 PM

#

@dusty citrus Sound is the dividing line between subsonic and supersonic fluid dynamics because sound waves travel at the speed of sound, by definition. Shock waves are a supersonic phenomenon.

#

If an object travels at less than the speed of sound, there's a pressure gradient in front of it telling air molecules to get out of the way and flow around it. But this "information" can't travel faster than the speed of sound.

dusty citrus Nov 9, 2019, 9:38 PM

#

Speed of sound is near 767 mph and varies (considerably) by weather.

hardy rock Nov 9, 2019, 9:39 PM

#

At supersonic speed, the air more or less crashes into the moving object because it doesn't "know" that the object is coming. Shock waves are sharp (infinitely thin in theory) areas where there's a sudden discontinuity in pressure.

#

And sure, bullets are supersonic and create shock waves. That's where they were first observed afaik. But they aren't big shock waves because they aren't as big as airplanes. 😁

dusty citrus Nov 9, 2019, 9:40 PM

#

I think to keep aircraft from engine trouble they try to move the nodes the turbulent air makes away from the engine inlets.

#

Wow

hardy rock Nov 9, 2019, 9:43 PM

#

Mechanical and Aerospace Engineering degree, gotta be good for something. 😀

#

@dusty citrus Sure, turbulence and shock waves/transonic effects are pretty much different problems but there's a lot that can go wrong. And from what I know about it most of the potential issues were discovered because something did go wrong and no one could figure out why.

#

When planes start creeping up above maybe 500 mph, local areas of airflow can be faster than that, fast enough to approach sonic speed, which is lower at high altitude btw. WWII fighter planes in a dive could go fast enough to experience strange effects where the control surfaces stopped working, for example.

dusty citrus Nov 9, 2019, 9:48 PM

#

I've forgotten which aircraft it applied to, but during design and testing of one I was reading about, I think they developed some kind of a moving plate to move the turbulence away from the jet engine's intake, while in flight under changing conditions (fighter/bomber configuration, probably)
(maybe swept wing)

#

The thing that always gets me about people's ideas of visiting another star (a different solar system) is the speed of impact with any debris in the path.

#

NGT said that to Jupiter, it's 10 years .. and 20 to Saturn (one-way).

#

70k years to the nearest star (besides Sol).

#

That's with any Delta-V solution we know about.

Shockwaves emanating from a bullet: https://en.wikipedia.org/wiki/Bullet_bow_shockwave#/media/File:Supersonic_Bullet_Shadowgraph.jpg

Bullet bow shockwave

A bullet bow shockwave is a physical and audible wave created in the air when a bullet travels at supersonic speeds; meaning faster than the speed of sound.

The bullet bow shockwave is the result of air being greatly compressed at the front-most tip of the bullet as it slice...

(Neil deGrasse Tyson was mainly interested in explaining interstellar travel times, but it was a bit of a buzzkill to learn how far away it is to travel to Saturn)

#

He was trying to advocate for mining asteroids rather than the rings of Saturn (for example).

#

A pilot friend of mine pointed out the obvious: it takes delta-V input to 'slow the asteroid-mined material' to get it back to Earth.

#

It's mass.

#

And it's moving (fast).

#

So basically even mining an asteroid is an unsolved problem, except for the ones that happen to have compatible trajectories (no idea if that's even possible).

#

By definition a small delta-V relative to Earth's orbit must be in orbit about the Sun, at about the distance of the Earth.

#

In #help-with-linux-sbcs there was discussion about limiting quantities purchased, and an odd pricing structure that went up with quantity.

#

The way I look at it, you are a purchasing agent. You are in their store - they have your attention.

#

If they can sell you one of an item that they are apt to sell out on, early, before xmas shopping spree has peaked, then they have sold one item to a purchasing agent that they (still) have the attention of.
Who (now) has free spending resources available, since they were 'disappointed' with not being able to buy two of that (initial) item.

#

Now, they have inventory remaining, to do this (similar kind of transaction) with a different purchasing agent than yourself.

#

One that can make buying decisions entirely independent of that first (you) purchasing agent.

#

I'm guessing the math favors gaining the attention of more purchasing agents, rather than fewer of them; part of that strategy is to have nice inventory available, that is wanted by many.

#

dusty citrus Nov 16, 2019, 7:26 PM

#

I could have it backwards; the datasheet is definitive on this as well (SDI vs SDO).

#

Obviously with only four terminals and two distinct serial protocols, some pin functions are shared between those two serial comm protocols.

#

Generally you design for only one use case (SPI or i2c) as an end-user.

idle iron Nov 16, 2019, 7:28 PM

#

yeah i think its a cool idea

#

confusing but cool...

dusty citrus Nov 16, 2019, 7:28 PM

#

I think I've seen three and four protocols in a single device (4 bit parallel, 8 bit parallel, SPI, i2c).

#

Sometimes with stuff like that you have to remove a diode (or resistor) to enable the extra functionality of an added protocol.

#

I don't quite understand your level shifter, but in general, I think you do need separate pullups on each side of the shifting circuit.

#

The weak 10k pullups are probably ideal; I think strong pullups can be added where required.

#

Adafruit does sell a similar shifter I think. Very low part number (under 1000).

#

https://www.adafruit.com/product/757

#

That was the circuit I had in mind when I saw yours.

idle iron Nov 16, 2019, 7:34 PM

i was going to use the VHI pin for one side and never changed it thanks for reminding me, but this would be if someone solder bridged the pads on the back of the ItsyBitsy

#

I am pathological at avoiding mixing 3.3 and 5v devices.

I did manage to deal with a 5v character LCD a few times.

The new STM32F405 target boards Adafruit is selling are 5v tolerant, 3.3v devices.

idle iron Nov 16, 2019, 7:46 PM

#

all sensors are 3.3v good

dusty citrus Nov 16, 2019, 7:46 PM

#

The .PNG should bring more eyes onto your hard work, here. ;)

idle iron Nov 16, 2019, 7:46 PM

#

ill just use the 3.3v

#

adding capacitors...

dusty citrus Nov 16, 2019, 7:47 PM

#

I only know what I know. /Nasrudin

#

If they're all 3.3 good what's with the level shifter?

#

Okay I assumed it was a level shifter. Both sides pulled up to 3.3.

#

And one signal is SDA_3V the other is SDA

#

hence my confusion ;)

#

Pretty sure a 5V SDA/SCL bus must be pulled up to 5V not 3.3

#

The main thing with the i2c bus has to do with the fact that you can bring one of the two lines to ground, to signal, I think.

#

I think the idea was that you could do so harmlessly, without knowing 'who else' is using the bus at the moment.

#

So the 'Open Drain' thing applied (or somesuch).

#

Most port pins (GPIO) can be asked to be setup as Push-Pull.

#

That allows them to (for example) light up an LED.

#

But there's another mode where that is not the case (which is why you set them up as push-pull).

#

A third mode is 'input' mode.

#

It doesn't take long to read through why these things are, but usually there's example software that sets all this up for you, so I don't have it memorized.

#

Can someone explain this to me?

dusty citrus Nov 16, 2019, 7:58 PM

#

sorry it's mostly empty and you can see the inside walls

#

I don’t have my finger in it

idle iron Nov 16, 2019, 7:59 PM

#

how many bubbles are in the straw?

dusty citrus Nov 16, 2019, 7:59 PM

#

The pressure in the air column above the liquid, in the straw, is low enough to allow the liquid to rise in the column above the level of the reservoir.

#

Wait, maybe I did have my finger on it without thinking about it when I took the picture

#

So this is an air pressure thing?

#

I think it is. Too high to be something else.

#

If it were say less than 1/4" above the reservoir you could entertain other notions.

#

I had a barometer on my wall. It was a reservoir and a standpipe.

#

The standpipe would overflow during a deep low in the atmosphere.

#

Like during a Nor'easter.

#

The interior reservoir had no air inlet at all. It was sealed by the water at the standpipe.

#

But honestly, I think I did have my finger on it without thinking

#

Then there can’t be change in pressure

#

Well here's the thing. When you raised the straw, you raised the water trapped in the straw, too.

#

So, when I don’t have my finger on it, how does the pressure lower to where the rest of the soda is?

#

The atmosphere is 15 lb per square inch.

#

15?!?!

#

There can only be less pressure than 15 PSI anywhere in this system; never more.

#

Yeah air weighs an awful lot.

#

How are we not dead?

#

15

#

A hot air balloon displaces hundreds of pounds of air, using only the envelope of the balloon.

#

(and the inside of the balloon also has air in it, but at a much lower density).

#

And that lower pressure air wants to diffuse to where its respective level of concentration is, which is higher up the atmosphere

#

Pretty cool

#

Your hominid envelope was designed around the 15 PSI containing pressure.

#

That's why you feel ill (mightily) when they 'space' you out the airlock of the ship. ;)

#

But seriously

#

15

#

It's holding you together; don't resent it. ;)

#

Ah, that makes sense

#

But maybe I’m misrepresenting this

#

Well here's another thing: at the 850 millibar level, 85/100'th of the 'weight of the sky' is still above your altitude.

#

To me, 15 lb per sq inch sounds like the weight of a 15 pound sand bag for every sq inch of volume I take up

#

That means 15 percent of it is below you.

#

Yeah that's pretty much it. 15 lb/in^2 is a doozy.

#

But it's applied from every side at once.

#

It doesn’t feel like I’m carrying hundreds of pounds right now, so I’m confused

#

Oh, god...dynamic physics

#

And, madbo is here

#

Lmao

#

The wind resistance at 20 MPH on a bicycle is responsible for the overwhelming large majority of the opposing force you have to supply.

#

Basically all your energy is taken up overcoming wind resistance at 20 MPH, on a bicycle.

late fulcrum Nov 16, 2019, 8:09 PM

#

The pressure from without is balanced by the pressure from within, so there's no net force. Have you seen the demonstrations where a container is filled with steam, sealed, then cooled, and it collapses? Atmospheric pressure is the force that can make (in at least one case) an entire rail car collapse.

You'd be surprised. It is possible to go below zero pressure under some circumstances (which are MUCH more common than you probably imagine). It's what gets water from tree roots up to their leaves.

I think on a board you may want a small disc cap across /RESET.

0.01 uF or maybe 0.1 uF.

#

whatver adafruit sells is fine there

they got 0.1 uF in the shop

I have 100 nF across the switch. 100k to Vcc pullup.

idle iron Nov 16, 2019, 8:46 PM

#

so 100k for sda scl not 10k?

dusty citrus Nov 16, 2019, 8:46 PM

#

Adafruit doesn't seem to use either.

#

No this is just for /RESET

#

The C8051F330D datasheet probably has the reset circuit, or for its evaluation board.

idle iron Nov 16, 2019, 8:47 PM

#

oh okay ill add a resistor, yeah i dont see them adding them to addon boards

dusty citrus Nov 16, 2019, 8:49 PM

#

The 100 nF cap is for bypass and/or switch contact de-sparking type ideas, probably.

idle iron Nov 16, 2019, 8:49 PM

#

there is still lots of room on this board could fit another I2C too i think

dusty citrus Nov 16, 2019, 8:49 PM

#

The 100k (very weak) pullup on /RST is probably to assert it when not reset.

#

(rather than letting it float)

#

Could be device-specific.

#

c2 interface requires a bit more finagling

📎 c8051f120-dk-reset-a.png

#

I don't think the F120 has c2 come to think of it. ;) Probably JTAG only.

#

main point: find the development kit's eval board schematic and copy it.

#

If it hangs extra doo-dads on a subcircuit (such as /RST) follow their lead.

what is sw2?

the reset looks cool

dusty citrus Nov 16, 2019, 9:01 PM

oh irrelevant for me but still interesting

dusty citrus Nov 16, 2019, 9:03 PM

#

Yeah it's just a toy switch for experimenting.

#

The jumper omits it if you didn't want/need that toy.

#

(P3.7 is just a GPIO pin here) (PC_7 in Atmel-speak)

#

They use P1 P2 P3 instead of PA PB and PC.

#

There may be pin sharing of function on /RST and that explains the extra components near the reset.

#

On their DIP20 packaged version of a similar series chip this is explicit.

late fulcrum Nov 16, 2019, 9:07 PM

The washing machine was making a clattering noise during the drain cycle, so I checked the pin trap and found this rainbow-hued dime. Normally I see colors like that on niobium or titanium, I'm not sure what would cause this effect on an ordinary dime.

@idle iron Looks like someone used 100k to Vcc pullup on /RST on the C8051F330D with 0.1 uF bypass disc ceramic cap across the pushbutton on this schematic I found.

#

Nothing else.

They probably copied the dev kit schematic's reset circuit from Silabs.

At first, I was going to use a MAX6817 debouncer, but I can't find where I put it. Then I thought I'd use Ben's 555-based debouncer, but then I realized I already have an Arduino pretending to be a bus analyzer, I can use it as a configurable clock oscillator/debouncer.

Hm. That's not VGA though. ;)

640x480 but look at the granularity of what the pixels are.

#

memory is expensive 😦

dusty citrus Nov 19, 2019, 6:46 PM

#

That's 307,200 pixels on the display at one time. ;)

#

If you have a ROM character generator, that reduces to 80x25 in some respects, but you still have to paint the text onto the 640x480 area.

#

I just assumed 'they' would have this by now - that you'd trip over them, they'd be so common.

When I referred to an 1802 generating video, I was thinking of Lee Hart's "VIP2K" computer the size of an Altoids tin: http://www.sunrise-ev.com/vip2k.htm

dusty citrus Nov 19, 2019, 6:57 PM

That lead image is kind of what I had in mind, but maybe all the way to 80x25.

#

Looks pretty much like a Don Lancaster TV Typewriter

late fulcrum Nov 19, 2019, 6:59 PM

#

Since the 1802 is doing the hard work, the video circuitry consists of a 74HC4040 counter, a 27C16 PROM as a video sequencer, and a 74HC374 as the video latch. Aside from a NAND gate and a few resistors, that's the entire video generator.

Here it is in operation (using a discarded karaoke machine as a video monitor)

Nice!

#

I've built (something like) ten devices over the years to answer one simple question: Is the (window-mounted) air conditioner (compressor circuit) currently: ON or OFF?

#

My last two air conditioners made such a small difference in noise when compressing and when not that I cannot always tell.

#

Eventually when it cycles down, it'll smell differently, but you have to stand there if you just happened to walk into the room ten seconds before it cycled down.

#

I want to be able to plant a foot, turn and pivot and be headed back to the other room, to check on it. For that I need positive indication that yes, or no, the compressor is on or not on. ;)

#

So the device I used this summer has a bank of 8 neopixels.

#

The bank of 8 RGB's represent past history of the compressor, in a 3-minute granularity.

#

(I think 3.5 or 2.5 might work better, as compared with the electronics governing this particular ACU's cycle-down process).

#

But, if I walk into the room and all eight RGB's are blue, I know it's been cooling for 3x8 minutes without an interruption.

#

If any are green, I know I sampled when it was transitioning (but don't know the direction).

#

If all are red, it's been cycled down for at least 24 minutes. ;)

#

I want to create a small mini 8 bit computer with a CRT screen

Lots of ways to do that. You could even do a vector display if you felt like it.

Many of the video games in the 1980s were 8-bit computers with a CRT.

What is a difference between a CLPD and a FPGA

late fulcrum Nov 19, 2019, 8:23 PM

#

They're all Programmable Logic Devices (PLD), but the difference is more one of scale than of kind. On the small end, there are Programmable Array Logic (PAL) devices, with a few dozen gates. Then there are the Complex Programmable Logic Devices (CPLD) with more capability, then Field Programmable Gate Array (FPGA) devices with even more.

#

One cool thing about the early PAL devices (like http://web.mit.edu/6.115/www/document/gal22v10.pdf) is that the data sheet actually shows the entire layout of the chip, and which bits control what. You could theoretically produce a fuse map to program it entirely manually.

dusty citrus Nov 19, 2019, 8:39 PM

#

I feel like FPGAs seem to be more easy

#

Arent they easy to program?

late fulcrum Nov 19, 2019, 8:46 PM

You can program any of them with VeriLog or VHDL.

#

#

I meant with cables

#

Because i heard you gotta do some bunch of Jtag stuff

late fulcrum Nov 19, 2019, 8:53 PM

#

Yes, you do need a way to get the fuse map into the device. Many use JTAG for that. You can either emulate JTAG with an Arduino, get a cheap USB-JTAG adapter, or get a board with a built-in JTAG adapter. Alternatively, some devices simply read their configuration from an outboard memory chip which you program with the desired fuse map.

#

Some of the earlier ones you program like a PROM by putting it in a programmer (these days, probably a TL866 of some flavor).

hardy rock Nov 19, 2019, 10:30 PM

#

@dusty citrus For CPU experiments you might need two usb ports: one for writing the logic bitstream to the device and another for a serial console so that you can see if it's working. My fpga board has a built-in one usb programming port, but I had to jumper a second one onto the pins to see the soft CPU working and type commands.

📎 upduino-picorv32-upython.jpg

#

It's possible for one USB port to have more than one virtual device--two serial ports, for example--but not guaranteed that an FPGA development board will be clever enough to do that. Mine wasn't.

If this kid in a local tech chat asks one more time how to normalize all the audio coming out of his web browser in real time I'm gonna eat him xD

#

Sure, we'll just dynamically preserve the shape of the wave when we have no moment-to-moment idea where the peak of the wave is going to be. I mean in theory there's post processing you can do but it requires taking samples, post processing, and wicked latency. Latency you either introduce to the display, or live with A/V desynch

#

Am I the one in the wrong? Is this not black magic? I've been doing AV for events for 10 years and as far as I've ever heard it's either impossible or prohibitively expensive

#

I mean I guess you could do it fast enough. With an ASIC/FPGA and hardware that lives in a rack that you sell to audio engineers for a pretty penny

sweet fiber Nov 21, 2019, 4:38 AM

#

you can just about do it with a small look-ahead buffer (20ms will give you >50Hz) which is what some of the older Behringer processors used to do. Otherwise you need a fairly big 'history' buffer, and huge dynamic range input to give you anything useful.
There are some shoutcast streaming 'levelling' compressors around, I'm not entirely sure what principles they use, but can't be far different from the basic techniques we've already discussed.

#

The main problem is what you normalise to as you assert in your OP 😉

im just worried, im happy below 1.4, but 1.5 is too high

fickle slate Nov 21, 2019, 8:24 PM

#

heh

#

how does the MOBO software figure change if you change the voltage>

lyric hull Nov 21, 2019, 8:27 PM

#

well you see, i really havent messed with the voltage at all, i told it to +.16 so theorectically should be at what cpuz says

late fulcrum Nov 21, 2019, 8:28 PM

#

You say you haven't messed with it, but you also say you told it +.16.

#

In any case, you should be able to measure the core voltage directly at a test point on the mobo.

lyric hull Nov 21, 2019, 8:28 PM

#

i havent changed it around when adjusting my clocks

#

like i had it at .16 from the start

late fulcrum Nov 21, 2019, 8:29 PM

#

So you changed the voltage to start with, then changed the clock, now you're trying to figure out what the voltage is that the CPU core is getting?

fickle slate Nov 21, 2019, 8:29 PM

#

then they must be reading a different seonsor?

lyric hull Nov 21, 2019, 8:30 PM

#

yes mad, cause i dont want the voltage to high or ill just set it back to a mild overclock

#

i thought so too c4, hence i asked why these are reading different figures

#

lemme check ryzen master

fickle slate Nov 21, 2019, 8:30 PM

#

change the voltage around and see how the different values go up/down

late fulcrum Nov 21, 2019, 8:31 PM

#

Your best bet is to check it with a voltmeter at a test point on the motherboard. The built in voltage measuring circuits aren't particularly accurate.

ryzen master

#

im guessing since its so close to hwinfo this must be accurate

fickle slate Nov 21, 2019, 8:32 PM

#

if the measurments where taken at different times they would be different

lyric hull Nov 21, 2019, 8:33 PM

#

they were all take right now

#

📎 unknown.png

fickle slate Nov 21, 2019, 8:37 PM

#

so

#

one of them might be the actual realtime voltage (cpu-z)

#

while the mobo might be reporting the max voltage

lyric hull Nov 21, 2019, 8:38 PM

#

also mad, i do get what youre saying but its a hassle getting to my physical pc right now xD

fickle slate Nov 21, 2019, 8:39 PM

#

for me, the CPU-Zvalue is around 0.5v with no load, and goes up to the amdryzenmaster value with load

lyric hull Nov 21, 2019, 8:39 PM

#

lemme put a load on it and take a ss mid load

late fulcrum Nov 21, 2019, 8:39 PM

#

One utility might be reading the output of the on-board Vcore regulator, another one might be reading what the CPU claims (MSR_PERF_STATUS, bits 24-32). Also, that CPU is multi-core and it's (very) possible for different cores to have different voltages at the same time.

fickle slate Nov 21, 2019, 8:40 PM

#

why my ram at 1200mhz if it should be at 2400:

📎 unknown.png

#

or is that supposed to be half the value?

lyric hull Nov 21, 2019, 8:41 PM

#

DDR

late fulcrum Nov 21, 2019, 8:41 PM

#

Because it's DDR (double data rate): it transfers data on both the rising and falling edges of the clock, so a 1200MHz clock gives 2400M transfers per second.

lyric hull Nov 21, 2019, 8:41 PM

#

double data rate, thus 1200x2

fickle slate Nov 21, 2019, 8:41 PM

#

during load the only value that really changed was cpuz

#

the other thing that bothers me is the high wattage of both the cpu +soc

#

sounds right?

lyric hull Nov 21, 2019, 8:51 PM

#

really?

#

huh

#

i just thought it high for a 65w chip, then again this is overclocked

fickle slate Nov 21, 2019, 8:52 PM

#

I mean yea that's high

#

but 65W could be the estimate of the power dissipated in the CPU itself

#

idk

lyric hull Nov 21, 2019, 8:53 PM

#

it is like at 3.8, all cores up from 3.2

fickle slate Nov 21, 2019, 8:53 PM

#

ohh

#

65W is the TDP

lyric hull Nov 21, 2019, 8:54 PM

#

aye

fickle slate Nov 21, 2019, 8:54 PM

#

so presumably the CPU actually does something and not all of that 180W of power becomes waste heat 😛

i have an interesting thought

#

vodka in a watercooled system instead of water

fickle slate Nov 21, 2019, 9:20 PM

#

Water has twice the specific heat of alcohol

lyric hull Nov 21, 2019, 9:26 PM

#

of pure alcohol yes

#

but 40% vodka has 85% of the specific heat of water

late fulcrum Nov 21, 2019, 9:42 PM

#

If you wanted to do vapor cooling at atmospheric pressure, vodka might work better than water. Otherwise, water-based antifreeze is probably your best bet until you get to exotics like gallium, mercury, and Fluorinert®.

fickle slate Nov 21, 2019, 9:52 PM

#

but antifreeze is still lower specific heat then water?

#

it just doesn't freeze right?

late fulcrum Nov 21, 2019, 10:07 PM

#

Yeah, water is pretty much the king of specific heat.

#

That's why a laser that can punch a hole through a quarter inch of steel in a microsecond won't do much more than a bad blister if it hits a human body (as long as it doesn't hit your eye).

ChromeOS is linux

Netbooks and such were intended to gain applications dynamically (from the Internet) and then discard them when finished (you keep the data but lose the executables).

TinyCore Linux has a similar idea going, so is often a good fit on a netbook.

sick adder Nov 25, 2019, 11:10 PM

@stray wind I'm open to ideas! but they need to be small 😦 the glass slides are approximately 1.2mm thick, so I need the width of the light to be less than that. That points me towards "0603" form factor LEDs..

hum these LEDs are the right size and are rated 60mA continuous at 25C ambient... OSRAM LS L296

late fulcrum Nov 25, 2019, 11:26 PM

You can put a row of them under your slides. I've been scouting high-power LEDs too, for a different project. It turns out it's easy to get bright orangish-red LEDs but the really red ones are trickier.

sick adder Nov 25, 2019, 11:29 PM

yeah I am looking at trying to fit 3 in parallel under the slide for each digit, then I need room for a transistor and 2 resistors for each digit. and now one digit represents a lot of solder points.

So what do you think.

Im not using PSN (Playstation Network)
for over many years anymore.

But im still getting E-Mails about "Hey you wanted to reset your password, click here". If I click the link I get redirected to official Sony website.

So what im beeing curios about is there really someone whos trying to get into my account somehow @8am.
Or could this be bait from sony?

grave crest Nov 28, 2019, 7:43 AM

#

A good rule of thumb is to never click on unsolicited links, unless you have specifically requested them -- as in, you are deliberately attempting to reset your password and the reset link was sent after your request to reset.

Phishing attempts are designed to look legit. Scarily so. There are a whole host of deceptive techniques used by hostile parties to imitate legitimacy, of which we won't specifically discuss here. The best decision would be to mark the email as spam, delete it, and never open such emails in the future.

#

It also could be a legitimate reset attempt -- someone tried to reset your password to gain access to the account, not understanding they'd need access to your email account.

Regardless, it would be prudent to use this experience as an opportunity. Take some time to do a proper password audit.

Here are some tips:

Change all of your passwords for all of your accounts (via the legit method on each service), ensuring they're all complex (random strings or XKCD-style word strings).
Don't neglect your security questions -- "What city were you born in?" can be easily guessed. Populate that field with a different random password.
Use a different password for every account. Don't reuse any password or component of a password.
It's strongly recommended to use a tool such as 1Password, LastPass, KeePass, etc to maintain your passwords. Such tools are great repositories for serial numbers, important details, etc. Ensure the database is protected by a very strong master password, and the database itself is encrypted with the best possible protection.
Lastly, enable 2FA (Two Factor Authentication) with any service that permits it. There are two components to good security: something you know (password) and something you have (cell phone). This can make things inconvenient if you're don't have a mobile surgically attached to your hand/head though.

I got the Arduino M0 Pro and my next target was Feather M0 Express, as soon as it was out.

#

Sometime I'm going to learn how to use that M0 Pro's debug port. I think 'OpenOCD' or somesuch is supported for itt.

Do i use vinegar to remove it?

late fulcrum Nov 30, 2019, 7:07 PM

#

You want to do three things: neutralize any remaining chemicals, remove debris, and clean the contacts. How to neutralize it depends on what kind of chemistry the power source was (LeClanche, alkaline, lithium, or whatever).

dusty citrus Nov 30, 2019, 7:08 PM

#

Its only the contacts that have corrosion

What kind of power source?

dusty citrus Nov 30, 2019, 7:09 PM

#

Duracell alcaline

late fulcrum Nov 30, 2019, 7:11 PM

#

Yes, for alkaline cells, vinegar is a good way to neutralize it. Then wash away the vinegar with alcohol or water (you don't want to leave any vinegar behind either), then polish the contact with a contact burnisher if you have one, otherwise an eraser, wire brush, knife edge, or even a nail file (but go easy with a nail file, you don't want to to through the plating). Then a final wipe with a damp cloth or tissue to get any debris from the polishing and you should be good.

This is actually amazing

dusty citrus Dec 1, 2019, 8:01 PM

_I'm trying to eradicate 'extra' uses of 'actually' today.

I came up with 'in fact' and '.. is, itself' as antidotes for three minutes thought, on this one. ;)_

#

'This is actually what I had in mind' vs 'This is, in fact, what I had in mind'.

#

(All due to something Martin Amis said (on stage, with Christopher Hitchens, in 2007) with regard to (in his, view, the repugnant) use of '.. went all-pear-shaped' as well as 'been there, done that, got the t-shirt' as (iirc) 'cliche' expressions).

"Even an idiot could see that..."

dusty citrus Dec 1, 2019, 8:07 PM

#

A child of five could solve this .. fetch me a child of five ;)

#

Reusing someone else's clever idiom, once it has reached mass appeal (and repetition) is what I think he meant.

#

This isn't right .. this isn't even wrong (I think Pauli is the correct attribution for this one)

#

I think the two of them agreed (on stage) that this misuse was where the writer (or speaker) stopped thinking for themself.

#

Then I came up with 'pet vocabulary' as not the same .. that's different (and they're not always idioms; they can be singleton words).

#

I use utterance and leverages all the time; they are in my pet vocabulary. Partly because nobody has picked up on them and popularized them, to the point where it embarasses me, or I cannot any longer get away with their use, without sensing I'm (ahah) .. leveraging a popularized vocabulary word. ;)

#

actually is particularly annoying to some native speakers of English who are not United States-ian.

hardy rock Dec 1, 2019, 8:13 PM

#

I wish I had some examples close at hand to give, but I often notice how metaphors can get frozen into language until the person using one of them is no longer aware of the literal meaning.

#

That seems to be part of the nature of language.

dusty citrus Dec 1, 2019, 8:14 PM

#

This is where I'm self-attacking the use of 'actually' from .. its literal meaning (which I take should involve an action of sorts).

#

So I'm listening to myself as I speak (especially) for its misuse .. and correcting (Restating, 'really' .. there's another one!) .. on the fly, as it were (possibly another one: on the fly).

#

oops both are. ahah. 'as it were' was the one I think I triggered harder on.

#

One of the reasons I still use 'as it were' is because it's never quite fallen into popular usage.

hardy rock Dec 1, 2019, 8:21 PM

#

At a place I once worked, there were a couple of not native English speakers who used "actually" in every sentence, and sometimes more than once. Made me wonder how they landed on that, if there was some connection to a feature of their first language.

#

Once was from China which has many languages. The other was from Nigeria which is also a linguistic Easter basket even though English is the official language there.

dusty citrus Dec 1, 2019, 8:23 PM

#

James Gleick says that language has built-in redundancies, which is why we often 'get' what others say when they don't (actually, haha) [in fact] say what they wish to say.

#

lol 'linguistic easter basket'

#

You get 100% credit for that one. ;)

hardy rock Dec 1, 2019, 8:24 PM

I made it up "on the fly" actually.

hardy rock Dec 1, 2019, 8:26 PM

#

It does take some effort. There isn't always time, and there's also a risk of being misinterpreted or offending someone in a way that wasn't anticipated.

dusty citrus Dec 1, 2019, 8:27 PM

#

As an aside, if your typing partner (in a text-only Internet-driven channel) begins a sentence with:
Am not sure vs I am not sure you are very likely in conversation with a Nigerian speaker.

hardy rock Dec 1, 2019, 8:27 PM

#

Interesting fact!

dusty citrus Dec 1, 2019, 8:27 PM

#

It's a hallmark of the Nigerian scammer.

#

They cannot seem to catch every instance of it while scamming you.

#

The scammer I encountered combined three very unlikely ideas into a single sentence, twice, a few months apart, and hadn't realized what a signature that was, for me (I remembered it from the first time).

#

One of them was F1 racing (formula One autosport)

#

The other two were less memorable, but the combination of the three into a single utterance (there's one of my pet words, again) .. was telltale.

If you're soldering, that may be a mismatch .. the vid might be the better route.

For some reason, podcasts that were never filmed (prepared using only a microphone) don't seem to have the same veracity as the filmed/video'd equivalent.

I've got all 20 stages of the Vuelta a España on the disk, about 3 months old now and I'm only halfway through. (Off NBC Olympic Channel IIRC.)

#

It's colorful and things happen but they don't matter that much. The Spanish countryside is nice to see, more arid and not as green as France in the spring in Le Tour.

dusty citrus Dec 1, 2019, 8:55 PM

#

That's great. I have not specialized in watching peloton racing .. I enjoyed the Olympics (Beijing, I think) and those peloton coverages; I don't really remember why the practice (of watching them, complete) didn't stick, but I will say that downhill skiing, and megavalanche races still attract my full attention, if I bother to.
megavalanche in particular I can't stop watching until the very end. ;)_

There was also a vid on urban downhill cycle races that was fascinating to me.
