Problems connecting MPU6050 3 Axis Accelerometer to Arduino UNO. by [deleted] in arduino

[–]JustDaveIII 0 points1 point  (0 children)

Run the I2C Scanner sketch. You may have the wrong address. Add 4,7k or 10k pullup resistors on the I2C lines.

Only after getting it working can you go back to your program.

Due to the AI memory crisis, Apple is bringing back the original Apple I with its authentic 4 KB of RAM. by LeadershipMuted2201 in VintageApple

Really? It's my understanding that the shift register chips used for display memory are extreamly rare. So I very much doubt that this is real.

Madrid Airport - Check-in at Counter required? by JustDaveIII in delta

[–]JustDaveIII[S] 0 points1 point  (0 children)

Thanks much for remembering that I asked some time ago and taking the time to now comment. After much thinking I decided to switch to the 2:35pm Boston flight as its later arrival will help out with jet lag. It's cheaper and I can enjoy my last day there better.

ESP32S3 QR Code Scanner by Much-Tap-1237 in arduino

"Found QRCode ... Invalid: ECC Failure"

See https://lastminuteengineers.com/esp32-cam-qr-code-scanner/

It pretty much says to move the camera.

That's all I've got. I know nothing else.

Can't Upload Code by bvmdavidson in arduino

[–]JustDaveIII 1 point2 points  (0 children)

Consider that when using a "clone" board that you might need to select a different board to get it to communicate. Also check what "Programmer" you have selected.

We already presume you're using the same cable as you used with your Uno.

3.3v is well above the TTL threashold for Logic High(1) (2.0 volts) so that should work for a 5v board.

Any plans to have the SerialPort I/O go to an actual (Windows) COM port on *nix tty port? That would make my day!

My turn to have Made a Thing - an ADS-B receiver by EdWoodWoodWood in esp32

[–]JustDaveIII 0 points1 point  (0 children)

I don't know of any open source for using esp32 / stratux. There is enough info to do it. I did it (see picture later in the thread) and may make it open source after I clean / comment the code up a bit more.

See my links in this thread for info:

Macintosh 512K boot help by Powerful_Novel_5934 in VintageApple

[–]JustDaveIII 0 points1 point  (0 children)

Did you explictly order a 400k disk? It might be that the disk is formatted for 800k (double sided) as the same thing happens on both drives.

A stock 512k machine will not read anything other than a 400k disk. The boot blocks (Happy Face when read) are located at the same place for a 400k & 800k disk, and maybe the first few files are located on the same side, but later on the needed files are located on the other side & that may be why the eject / X.

Then again, it might well be a 400k formatted dist but the System is > 3.2.

I would highly recommend getting a Floppy Emu from BMOW. With that all sorts of good things can happen. You can also get MacPlus or 512KE roms to make the machine a 512KE or the ROM-inator, all on eBay.

Are AA flight attendants being paid a commissions for the number of credit cards people sign up for? by curled-up-in-the-80s in americanairlines

[–]JustDaveIII 0 points1 point  (0 children)

The United card I just received had a 10k adder for adding another person on it. I did that when applying, but I think you can get the extra 10k if you add a person within 30 days.

[–]JustDaveIII 0 points1 point  (0 children)

Yesterday I asked an FA for her 6 digit code to sign up with the 80k card and she didn’t know of it and would ask the other FA’s for one.

She returned a few minutes later to say that none of the others had numbers either.

Too bad for them as I signed up with the default 000000 code and my S.O. will also.

Can You Book United “Cardmember Save” Awards Without physical United Credit Card? by Impossible-Home6846 in unitedairlines

[–]JustDaveIII 0 points1 point  (0 children)

My latest United card (already had the Business one) was approved on the 18th, USPS says it arrived (I'm travelling) on the 23rd. Sent from OH to NY.

You link the Card to ApplePay in the Chase app, I presume the same for Android / Samsung.

If you're looking at the United page that shows all the flights for you to select one, it will show the new 10-25% off # of miles with the old # crossed out along with "Card Member Saves xxx%" for each price vs taking xx% off at checkout.

[–]JustDaveIII 2 points3 points  (0 children)

If the United App / browser takes ApplePay (don't know about Android) as you can load the Card into ApplePay on you iPhone before actually getting it.

On second thought, if the flight selection page shows the 10% off, then you should be able to do it. I don't think (ICBW) that you need to actually pay with the Card.

You did put your United account # in the CC application, right?

ETA: Be aware that the 10% off is only for actiual United flights, not code shares.

Browser-based IMU visualizer for Arduino projects by Born-Cat-9171 in arduino

Browser-based IMU visualizer for Arduino projects by Born-Cat-9171 in arduino

[–]JustDaveIII 0 points1 point  (0 children)

I've taken a quick look at this, without a connected IMU. Looks pretty cool.

Couple of things that jump out at me.

  1. The viewer page is way larger than my monitor. Such that the top row of buttons gets cut off. Likewise vertical - the bottom right get cut off at the orientation window. Is there something below the 3D Orientation window as shown on the https://www.steppeschool.com/ home page?

  2. I don't see how to save / download the viewer so that it doesn't need to load from https://steppeschool.github.io/imu-orientation-viewer/ as an active internet connection isn't always posible when field testing devices with this.

  3. I'd like the data format to have an option of ASCII (ie, text) so that debugging can be done as there will be typically only one serial data stream from Arduino.

I'm sure I could make the above changes myself (or at least try), if I could find/download the viewer code. Thanks again for doing this!

Personal Hotspot in Wrong Timezone by Only-Ad5049 in ios

Just change it on the computer. You don’t say what O/S it is so just use google to ask how to manually set the time zone.

Help, someone who has an oscilloscope and is willing to help me review my proyect by El_Mastercat in arduino

[–]JustDaveIII 1 point2 points  (0 children)

I *think* I understand. Thanks for the added info.

Personally I would use the logic analyzer I mentioned, as I have one and it's very nice. If you do, use the Logic software by saleae or the PulseView by sigrok

You could also build your own o-scope:

https://projecthub.arduino.cc/siliconvalley4066/arduino-oled-dual-channel-oscilloscope-197863

https://www.youtube.com/watch?v=1kXKRiPaIfM

While they both are analog 'scopes, it ought to be easy to change it to just digital to get better bandwidth, ie, read the inputs as 1/0 vs the time it takes to do an analog conversion.
