Of all the things we do at Raspberry Pi, driving down the cost of computer hardware remains one of the most important. Even in the developed world, a programmable computer is a luxury item for a lot of people, and every extra dollar that we ask someone to spend decreases the chance that they’ll choose to get involved. So, now a days every one needs cheap raspberry pi, to complete Cheap Raspberry Pi Projects.
Here are some Cheap Raspberry Pi Projects
1. A cheap Bluetooth serial port for your Raspberry Pi
While working on my Arduino based robot vehicle project the idea came to me that the Bluetooth module that I’m using as a remote control receiver for my robot would make a great addition to my Raspberry Pi. In this article I describe how to enable the Raspberry Pi’s serial port to talk to other devices over Bluetooth using this module.
2. Child Safety: How to sandbox your children’s web traffic cheaply using a Raspberry Pi
Heavy Disclaimer Although the Raspberry Pi described here is super cheap, you will have to have some slightly specialized network equipment to do this. In particular you will need a VLAN aware network switch and a VLAN aware Wifi Access Point at a minimum. These used to be costly but are getting cheaper. I HIGHLY recommend the:
- Ubiquiti UniFi UAP Indoor Scalable WiFi Access Point – around £50.00
- Ubiquiti TOUGHSwitch 5-Port PoE Switch- around £90.00 I have fallen in love with Ubiquiti network products. They offer you the power of a corporate network for home user cost.
3. Raspberry Pi Cheap DIY ATX-Power Switch.
Ok, so it doesn’t look like much…. But why would you need one?
Well you don’t, it is helpful if your pi is powered by a supply that also powers other things. A 3D Printer in my case.
Also included is a separate shutdown button which powers down the Pi.
After the Pi cleanly shuts down then power is removed from the Pi completely.

4. 8 superb — and cheap — Raspberry Pi alternatives
As great as the Raspberry Pi is — and let’s be honest, all of the devices in that family are excellent, especially for the money — it’s not the only such device available to buy, and some of the rival systems are arguably better as they come with Wi-Fi built-in, and other tricks, such as the ability to double as a wireless router, run Android, or display on-board scrolling messages.
5. Cheap solderless reset button for Raspberry Pi
This is my first Raspberry Pi. I’ve bought it as an XBMC home-theater box (and a “we’ll see later on what else”).
One of the annoying things I’ve found out right away was that it didn’t have a reset button. You can politely shut down the thing from software, but how do you turn it back on?
6. Cheap and Easy Guide to Building a Private Telephone System
Due to the proliferation of cellular networks, most homes have abandoned their land line telephone plan. The infrastructure is still there though, hidden in our walls. Why let all that copper go to waste? Let’s talk about how inexpensive and easy it is to reclaim this technology, making it useful again in today’s internet connected world. For detailed information for taking what you learn in this Instructable and building it directly into the phone lines in your home check out another one of our Instructables,

8. Adding an external power supply to a cheap USB hub
One day I found myself in the need for a USB hub with an eternal power supply but when I went to a shop I verified they can be quite more expensive than the ones that don’t have external power supply. No big deal, “I’ll just by a cheap one and add the external power supply”, I thought. And that’s what I did! After all I just had to add a wire on VCC, another on GND and cut the VDD wire of the USB cable that connects to the computer..
