Setting WiFi up via the command line. This method is suitable if you don't have access to the graphical user interface normally used to set up WiFi on the Raspberry Pi. It is particularly suitable for use with a serial console cable if you don't have access to a screen or wired Ethernet network.

To reach the goal of a chiptune/MIDI bluetooth Ukulele we have to :

1. Build a playable ukulele
2. Make it sound as an original gameboy
3. Send it in a bluetooth chip to convert in MIDI

1. Build a playable ukulele :

The idee for this ukulele it's can be build without any modification of the gameboy shell without adding screw or glue.

In this intention I design a neck 3D print in one piece for an easy production and a better sound with standard ukulele tuner which can be found cheap an easly on the net .

The other piece which need to be build is the bridge. After week of trial, I found the best place is in place of START/SELECT buttons. With screw in the actual holes to fix it and supporting the strings tension.

About the strings tension, they are big enought to bend the plastic of the body. To reinforced the body I design a plate to replace the PCB and contercare the tension. Dmg file viewer windows 8 windows 7.

2. Make it sound as an original gameboy

DMG is used for disk image files on Macintosh computers running Mac OS X. This file extension replaces the older file extension IMG which was discontinued during the release of later series of Mac operating systems. You can open DMG file on Mac, Linux, and Windows operating systems but it will require additional software to be installed on Windows. Dmg not opening on my mac.

The Game Boy has four sound channels: two square waves with adjustable duty, a programmable wave table, and a noise generator. But a yukulele get 4 string so it can't be use for it.

This audio-processor as all of this vintage console are not product anymore, so the best thing to do is to recreate this sound string by string.

Actual ukulele or other instrument pickup sense all strings at the times and the strings are not in metal, wich reduce the choise for the sensor. After some try I choose IR reflective sensor which are not so expensive and the consumsion are low (20mA each sensors) sun light resistant and with a good string sensibility.

The sound of the string is square-up with a fuzz effect with logic-gate use as amplifier to get the vintage touch and the warm of analogic sound.

All strings square sounds are mixed-up and send via a 2W amplifier to a speaker or headphone wich can be trim by thumbpot potentiometer.

3. Send it in a bluetooth chip to convert in MIDI

The power is provide by 4xAA battery from the original battery.

For the MIDI convertion we need for eache string this dynamic/volume signal and the frequency/note. Each of this signals is provide by the pickup and the fuzz effect wich square up the signal and send it to the ESP32.

Fer bluetooth connextion, I choose the cheap and easy ESP32 and a screen to enter into the menu with the gameboy playable buttons

All of the electronic and sensor will fit in one pcb.

software is not my best, but with the help of the maker community it will be possible!

This method is suitable if you don't have access to the graphical user interface normally used to set up WiFi on the Raspberry Pi. It is particularly suitable for use with a serial console cable if you don't have access to a screen or wired Ethernet network. Note also that no additional software is required; everything you need is already included on the Raspberry Pi.

Using raspi-config

The quickest way to enable wireless networking is to use the command line raspi-config tool.

sudo raspi-config

Select the Network Options item from the menu, then the Wi-fi option. On a fresh install, for regulatory purposes, you will need to specify the country in which the device is being used. Then set the SSID of the network, and the passphrase for the network. If you do not know the SSID of the network you want to connect to, see the next section on how to list available networks prior to running raspi-config.

Note that raspi-config does not provide a complete set of options for setting up wireless networking; you may need to refer to the extra sections below for more details if raspi-config fails to connect the Pi to your requested network.

Getting WiFi network details

To scan for WiFi networks, use the command sudo iwlist wlan0 scan. This will list all available WiFi networks, along with other useful information. Look out for:

1. 'ESSID:'testing' is the name of the WiFi network.

2. 'IE: IEEE 802.11i/WPA2 Version 1' is the authentication used. In this case it's WPA2, the newer and more secure wireless standard which replaces WPA. This guide should work for WPA or WPA2, but may not work for WPA2 enterprise. For WEP hex keys, see the last example here. You'll also need the password for the wireless network. For most home routers, this is found on a sticker on the back of the router. The ESSID (ssid) for the examples below is testing and the password (psk) is testingPassword.

Adding the network details to the Raspberry Pi

Open the wpa-supplicant configuration file in nano:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Go to the bottom of the file and add the following:

The password can be configured either as the ASCII representation, in quotes as per the example above, or as a pre-encrypted 32 byte hexadecimal number. You can use the wpa_passphrase utility to generate an encrypted PSK. This takes the SSID and the password, and generates the encrypted PSK. With the example from above, you can generate the PSK with wpa_passphrase 'testing'. Then you will be asked for the password of the WiFi network (in this case testingPassword). The output is as follows:

Note that the plain text version of the code is present, but commented out. You should delete this line from the final wpa_supplicant file for extra security.

The wpa_passphrase tool requires a password with between 8 and 63 characters. For more complex passphrases you can extract the content of a text file and use it as input for wpa_passphrase, if the password is stored as plain text inside a file somewhere, by calling wpa_passphrase 'testing' < file_where_password_is_stored. For extra security, you should delete the file_where_password_is_stored afterwards, so there is no plain text copy of the original password on the system.

To use the wpa_passphrase–encrypted PSK, you can either copy and paste the encrypted PSK into the wpa_supplicant.conf file, or redirect the tools output to the configuration file in one of two ways:

• Either change to root by executing sudo su, then call wpa_passphrase 'testing' >> /etc/wpa_supplicant/wpa_supplicant.conf and enter the testing password when asked
• Or use wpa_passphrase 'testing' sudo tee -a /etc/wpa_supplicant/wpa_supplicant.conf > /dev/null and enter the testing password when asked; the redirection to /dev/null prevents tee from also outputting to the screen (standard output)

If you want to use one of these two options, make sure you use >>, or use -a with tee — either will append text to an existing file. Using a single chevron >, or omitting -a when using tee, will erase all contents and then append the output to the specified file.

Now save the file by pressing Ctrl+X, then Y, then finally press Enter.

Reconfigure the interface with wpa_cli -i wlan0 reconfigure.

You can verify whether it has successfully connected using ifconfig wlan0. If the inet addr field has an address beside it, the Raspberry Pi has connected to the network. If not, check that your password and ESSID are correct.

On the Raspberry Pi 3 Model B+ and above, you will also need to set the country code, so that the 5G networking can choose the correct frequency bands. You can either use the raspi-config application and select the localisation option, or edit the wpa_supplicant.conf file and add the following. (Note you need to replace 'GB' with the ISO code of your country. See Wikipedia for a list of country codes.)

Note that with the latest Buster Raspbian release, you must ensure that the wpa_supplicant.conf file contains the following information at the top.

Unsecured networks

If the network you are connecting to does not use a password, the wpa_supplicant entry for the network will need to include the correct key_mgmt entry.e.g.

Hidden networks

If you are using a hidden network, an extra option in the wpa_supplicant file, scan_ssid, may help connection.

Raspberry Pi 4 Model B

You can verify whether it has successfully connected using ifconfig wlan0. If the inet addr field has an address beside it, the Raspberry Pi has connected to the network. If not, check your password and ESSID are correct.

Adding multiple wireless network configurations

On recent versions of Raspbian, it is possible to set up multiple configurations for wireless networking. For example, you could set up one for home and one for school.

For example

Dmg-01 Shell Raspberry Pi 4

If you have two networks in range, you can add the priority option to choose between them. The network in range, with the highest priority, will be the one that is connected.
