Greetings. I come intending to spread the news of new technological peices of equipment, such as the private GSM network (#1), and I wanted to share these projects with the public as much as possible, in as much detail as possible. These projects are intended to make the cool more affordable, and are as follows:
#1: Private GSM cellular network module: This is a medium to high priced project, and can be described by its title: A private GSM cellular network module. Components are as follows:
1: BladeRF (Nuand)/PlutoSDR: $420/$150
2: Raspberry Pi 3/4: $35-$55
3: Power bank/Wall-USB power: $20 Max (may not be necesdary if using PlutoSDR)
4: Rubber duck antenna (2x): $20 (may not be necessary if using PlutoSDR)
5: Programmable SIM cards, SIM card reader and writer: $50
6: Raspberry Pi software (Yate & YateBTS): Download from Internet.
7: Signal amplifiers (for both RX and TX) for the Nuand BladeRF x40 (optional if using PlutoSDR)
8: A touch screen with keyboard emulator
Here are a couple of helpful websites:
Instructions: All instructions can be viewed here:
Extra #1: It is possible to call people outside of the network over the internet with additional, VoIP software, such as Asterix/Free PBX or 3CX for RPi.
Extra #2: I have come up with a total price for the project: $815.
Extra #3: You can use PlutoSDR instead of Nuand's BladeRF, and lower the costs from $815 to $355.
Extra #4: Additionally, you can attach additional BladeRF/PlutoSDR modules (up to 3 additional units) and enlarge the coverage area.
Extra #5: If you use PlutoSDR, you should be able to obtain a maximum range of 300 Ft., without additional equipment (i.e.: RX/TX Low noise amplifiers).
Extra #6: You can also add additional tranceiving modules to the computer to increase to overall range. So far, PlutoSDR will tranceive at up to 300 feet without additional equipment (such as amplifiers), and you can attach up to 4 modules in total to the main computer.
#2: Gaming system Pager-like network: This is possible, and should use some equipment used in the previous project: The Nuand BladeRF x40. However, instructions for this project are not available at this time.
Nintendo DS/DS Lite: $20 Average
Raspberry Pi 4 ($50-$70)
Software (RSA Public/Private key, & a Fake "Nintendo Certification" SSL Encryption Certificate)
Ethernet cable
DISCLAIMER: This project has been untested, so results are unavailable at this time. Please wait patiently for upcoming updates.
#3: Multi Camera Raspberry Pi Surveilance System: This project is somewhat complicated compared to the previous projects, but a little more affordable. It utilizes the following components:
1: Raspberry Pi 3/4: $35-$55
2: The official Raspberry Pi NoIR Camera v2: $15-$25 Average
3: Raspberry Pi 0 v1.3: Usually $5
4: Mini HDMI to HDMI cable: The price for this all varies on the length you choose. Here are some examples:
6Ft: $4.95 10Ft: $3.99 15Ft: $5.98 25Ft: $35.95 50Ft: $13.29 (Keep in mind these are all from different sellers as well.)
5: USB to C Power Cable: Now for this, you're going to need more than just one (or even more than two, depending on however many camera modules you choose to use.), because you're gonna need one for the main computer (RPi 3/4), and one for every camera module (Pi NoIR camera & RPi 0 v1.3). Pricing varies for these as well.
6: Ethernet cable: Now this is optional, if you want to connect the main computer to your internet router, you use an ethernet cable, if you want to use an old PC monitor instead, use that and a short length HDMI cable.
NOTE: This is untested, so the PC monitor may fail.
7: Raspberry Pi (3/4) Software: MotionEyeOS: You can get this for free off of the internet. Here's a website, for download and installation:
8: Multi port HDMI splitter/adapter: The number of ports is determined by however many camera modules you desire. Pricing ranges from $3.89 (2-port)to $46.99 (8-port).
9: HDMI to USB adapter: $1-$3
Instructions: What you're going to want to do first is power the Raspberry Pi 3/4 up and install MotionEyeOS. Instructions provided here:
After you've installed MotionEyeOS, keep the main computer running. After you've done that, you're going to attach the USB portion of the HDMI-to USB adapter to one of the 3.0 USB ports(which one you use doesn't matter)on the main computer. Then, you're going to attach the HDMI splitter to the other end of the adapter. Next, you're going to attach the Mini-HDMI-to HDMI cable to the splitter. This cable is going to go to the RPi 0 v1.3(slave computer). Then you're going to attach the NoIR camera to the CSI port on the slave computer. If you have more than one camera, do it one-by-one. Once you've done that, the next step is to fasten the camera module to whereever the camera is going to be (i.e.: A tree, using nails or screws). Next, you're going to run the power supply to the camera module(s). This is going to be either the Official Raspberry Pi Power Supply, or a USB to C wall adapter. If you're going to choose the wall adapter, the power supply will have to be a 5.1 Volt, 2.5 Ampere output for the slave computer(s). It is advisable to run the power supply cable(s) alongside the HDMI cable(s), even more advisable to fasten the power supply cable to the HDMI cable with zip ties. These are VERY inexpensive, costing an average of less than $1.00. After you've connected the power supply to the camera module(s), all that's left to do is connect either the Ethernet cable, the PC monitor, or both. With the Ethernet onnection, you can view the camera(s) from anywhere, anytime, over the internet. If you want a closed connection, use the PC monitor.
#4: Portable Raspberry Pi Radar: This project allows you to use StormPredator from Intelliweather to access NEXRAD radar images over the internet, and strap it to your body.
Components are as follows:
1: Raspberry Pi 4
2: StormPredator from Intelliweather
3: 5-7" TV screean OR touch screen with keyboard emulator
4: 50,000 mAh power bank
5: USB-to-mini USB C cable
DISCLAIMER: Instructions for this project are not available at this time.
#5: Arduino-based access control system: This project will allow you to put a computer-based, key-card activated lock on say, i.e.: Your front door, or your bedroom door. Required components are as follows:
1: Arduino UNO: $20 average
2: Genuino UNO: $3.50-$20.00 (Different sellers)
3: 12C LCD: $2.56-$489 average (Different sellers)
4: MFRC522 RFID reader kit: $8.99 (Inductive Twig (seller))
5: SG90 Micro servo: $2.57 (USA.Banggood)
6: LED (x3): Price varies by seller.
7: 220 Ohm Resistor: $0.14(
8: Buzzer: Price varies by seller.
9: Push-button: $0.25 Average
10: 6-12 Volt Power Source: This can be made by using a 9V battery.
Instructions: Instructions for this project are unavailable at this time. Some instructions can be found here:

I do want to thank Lax18, because while He did not have any part in these projects, He is responsible for some of the inspiration. Smile
