How to get invoice/receipt for App Store purchases.

If you’ve ever needed an invoice for an app or service you purchased from the App Store, you’re in luck—Apple makes it easy to access and print them. Here’s a simple step-by-step guide to help you:

Visit Apple’s Report a Problem Website

Go to https://reportaproblem.apple.com in your web browser.

Log in to Your Apple Account

Sign in using your Apple ID credentials. Make sure you use the same account you used to make the purchase.

Find Your Purchase

Once logged in, you’ll see a list of all your recent App Store purchases. Browse through the list to locate the app or service you need an invoice for.

Expand Purchase Details

Click the expand icon button on the specific purchase to reveal more details about it.

View the Invoice

Look for the “View Invoice” button and click it. This will open the invoice for that purchase.

Print the Invoice

Once the invoice appears, you can print it by selecting the print option in your browser or saving it as a PDF for your records.

Making an ON/OFF switch for WeMo Switch with Arduino+Ethernet shield

On this project I use an arduino uno with ethernet shield to control a Wemo Switch with a On-Off switch.

For this project you need:

  1. Arduino uno
  2. Arduino ethernet shield
  3. ON-OFF Switch
  4. 10k Ohm Resistor

Schematic

Arduino controls the wemo device over local network. When the status of the hardware switch changes, the arduino sends a SOAP call to the Wemo device to change the power status.

Here is the code for the Arduino:

(You need to change the wemoIP and wemoPort variables with ip/port of the wemo device)

Use Export for iTunes with SanDisk Clip Sport MP3 Player

To transfer playlists to SanDisk Clip Sport you need Export for iTunes version 1.8 or later. 

Version 1.8 has a new option to add Windows line endings (CRLF) to playlists file (m3u). If you use the default line ending of Mac OS X (LF), Clip Sport cannot read correctly the playlist file.

New Line endings option on advanced export options

You also need to export m3u file in the same folder with music files (mp3s). So you need to enable "Save m3u file in the same folder with tracks" option.

Transfer playlists and albums from iTunes to Sansa Clip+ MP3 Player

SanDisk Sansa Clip+ MP3 Player is #1 best seller mp3 player on Amazon. It's small, inexpensive, and has many features: microSD card slot, FM tuner, voice recorder. Sansa clip can play MP3, WMA, WAV, FLAC, Ogg, Audible formats but does not support AAC files. Lack of AAC support is a problem if you want to transfer music from iTunes.

Export for iTunes app is the simpler solution to transfer iTunes music and especially iTunes playlists and albums to a mp3 player like Sansa Clip.

On next video I'm demonstrating how to use Export for iTunes to transfer your music.

Some notes:

  • Sansa Clip does not supports AAC files so you need to enable: "Convert to MP3" on export options.
  • To load correctly the m3u playlist file, the music files (mp3s) and the playlists file (m3u) must be in the same folder to do this go to Advanced export options of the app and choose Save music files to: Playlist folder or Music files folder, and enable the option "Save m3u file in the same folder with tracks".
