Hi. I come bearing new technological peices of equipment, such as the private GSM network (#1), and I wanted to share these projects with the public. These projects are as follows:
#1: Private GSM cellular network: This project can be described by its title: A private GSM cellular network. Components are as follows:
1: BladeRF (Nuand): $420
2: Raspberry Pi 3/4: $35-$55
3: Power bank/Wall-USB power: $20 Max
4: Rubber duck antenna (2x): $20
5: Programmable SIM cards, SIM card reader and writer: $50
6: Raspberry Pi software (Yate & YateBTS): Download from Internet. Here's a website: yatebts.com/open_source/
Instructions: Instructions for this project are unavailable at this time. Here is a website which may be of use:

#2: Gaming system Pager-like network: This does not, in fact, use equipment such as the GSM tower. Instead, it uses an "information tunnel". Instructions for this project are not available at this time.
Components:
Nintendo DS/DS Lite: $20 Average
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 simpler compared to the previous projects, and 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.
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: raspberrypi.org/forums/viewtopic.php?t=203972
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: randomnerdtutorials.com/install-motioneyeos-on-raspberry-pi-surveillance-camera-system/
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: 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 comonents 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(superbrightleds.com)
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:
