OSES: Equipment

Rationale

Whenever possible, I try to select low-cost equipment and DiY philosophy so that you can work outside the University labs. So, get your own lab!.

Here is the list of the equipment needed to develop all the activities.

Personal computer and software for it

A PC is a must. If possible, I advise you to come to the classroom with your laptop.

And the following software:

Some time ago, I distributed a Linux virtual machine for Oracle VirtualBOX. This VM could on Microsoft Windows, Apple MacOS or Linux without installing estrange thing in your computer. This has been discontinued.

Raspberry PI computer

You need and embedded computer system. For this pourpose, I selected the low cost, well known and fantastic Rasberry Pi platform.

Pi2ModB1GB_-comp-500x283

Around 35 Eur.

This platform is only for amateur/hobby projects, not for industrial-grade project. Simply pay more and you can apply the same concepts to a professional system.

In the lab wi will use Raspberry Pi 2 model B, but I you get one, please but the latest verified mode B board (Raspberry Pi 4 B).

Rasberry PI complements

At least:

  • Display with HDMI or DVI input.
  • HDMI cable or DVI depending on your display.
  • USB keyboard and mouse.
  • 5V 3A USB power source (buy in serious comerces).
  • 16 GiB microSD card, class 4 (class 10 works for me). Brandded, please!!!!
  • RJ-45 Ethernet cable (and Internet connection).
  • WiFi also is feasible in some models

USB DVB-T Dongle

For the «Software defined radio» experience, the cheapest option is to use an USB DVB-T dongle compatible with RTL-SDR. You should check Internet for finding an appropriate one.

I am using a Conceptronic’s HDTV USB 2.0 dongle (ref. CTVDIGUSB2) and it seems to work.

Linux reports it as a ‘Dexatek DK DVB-T Dongle’ that include a Realtek RTL2832 and a Fitipower FC0013 chips.

NOTE: New versions of the dongle are not compatible with RTL-SDR 🙁

Around 20 Eur.

Electronic components

Some components to play with the ports of the RPi:

  • A LED
  • A 350 Ohms or about resistor
  • Dupont male-male, male-female cables
