A sandwich for a programmer. A ramwich 🙃

My girlfriend's computer had an NVidia Quadro 2000, but it was getting very hot and had never been opened, I opened it to change the thermal paste and I already took the opportunity to do some tricks that made my hand start to shake, I put a 60mm cooler and a little tape white LED, I connected one to the other at 12V, I glued the cooler with hot glue and the double-sided LEDs, I closed everything, I applied thermal paste and here is the result.

On what grand voyage will this vessel of wisdom embark this day?

NVIDIA is expected to launch its new video cards codenamed Blackwell in late 2024 or early 2025, and now a new leak suggests that the upcoming RTX 5090 should have a generational leap of between 60% and 70%.

Goals

Collect information about space, Receive exclusive images of the earth/moon, Store files 'over the cloud'. Every day the satellite would generate a series of random numbers with information coming from its sensors, including a geiger counter... will we receive the megasena numbers?!!?!

AND MAINLY: show everyone that nothing is impossible


The Format

Let's consider the CubeSat format, 100x100x100mm and a limit of 1kg. There are around 13,000 satellites in orbit, but only around 300 are CubeSats.


Communication

I believe the best way would be 2 frequencies, one uplink and one downlink.
Frequencies must be between 130 and 450 MHz [calculated?], and must be registered with the Amateur Radio Association.

  Because the satellite is not geostationary, it will only pass over Brazil a few times a day [a 120-minute window perhaps]. Because it is in an elliptical orbit, it would be necessary to calculate the distortions of the Doppler Effect [where the frequency is higher when approaching and lower when moving away]


Energy

Four sides with high-efficiency solar panels would be enough to power the interior and charge the batteries.
I believe that 4 common lithium batteries [the same as cell phones] would be enough.

Care must be taken with radiation. At 600km, the Earth's magnetic field will not protect much against solar radiation. A current limiter, some capacitors, switches and maybe even a Leiden Bottle can help.

It would also be interesting to try using coils to generate energy.

In projects I studied, I saw that the antennas consumed 300mW.


Control

Of course, we would not have the power to control the direction and rotation of the satellite, in this topic we will talk about computational control.

I thought of separate systems in order and hierarchy. BIOS, power control, logging system, arduino, payload.

-BIOS: it will be a microcontroller connected directly to the antenna, it will interpret and decode the signal, it will control the power system, based on the commands received by the antenna, and it will forward the packets to the Arduino.

-Energy control: responsible for managing the batteries and solar panels, it will also have the function of shutting down if the current exceeds pre-stipulated limits.

-Logging system: will record everything, all systems report to it, but are not controlled by it. It will be read by the BIOS in case of a report.

-Arduino: it will be the real 'brain' of the CubeSat, it will control all the 'payload' sensors.


Payload

This will be 'the payload' of the satellite. It will be controlled and will communicate through Arduino.
Bearing in mind the weight and size limitations, and considering that there will only be around 300g available, I was thinking about putting:

-Mini 4 mega pixel camera.
-GPS of at least 5Hz [5 updates per second] and at least 15 channels [ability to locate using at least 15 satellites simultaneously]
-Accelerometer, would be necessary to know when it will be pointing towards the earth, and necessary to calibrate other sensors.
-Barometer
-Magnetic field meter
-Geiger counter?!
-Series of light sensors such as LDR and infrared phototransistor. They would possibly also be used to measure the temperature of the Earth's surface.
-Thermistor, temperature sensor.


Antenna

In space, the fewer moving parts the better, remembering that we will only have one chance that will separate whether we have a satellite or 1kg of space debris. But, with the limitations of the launch, it is essential that the antenna 'emerges' from inside the satellite. I saw a very clever solution in a project:

The group used a metallic measuring tape [which tends to stay straight] folded around the satellite, and held in place by a thin nylon thread. When activated, the satellite heats a 'nichrome' wire or something similar to red-hot, cutting the nylon wire, thus opening the antenna.



So, let's take this project forward...?! Guys, this is what I managed to research, I ask for everyone's help, this project is possible

I managed to capture good performance up to 200 meters, in places where there are air traffic towers it is possible to capture the listening.

The charger circuitry and 2 AA batteries fit into an Altoids gum tin, and will run your iPod for hours! 2.5x more than you'd get from a 9V


Specifications:

Version 3 now works with iPhones and newer iGadgets!
5V output @ 500mA output
Fits in your pocket
Recharges just about any gadget with a USB cable
Uses any AA batteries!
Upgrade to C or D cells for a mega battery pack


Some numbers...

iPhone (all types): 3/4 full recharge
iPod video (tested, using alkaline batteries): 3hrs more video (1 full recharge)
iPod mini (tested w/rechargables): 26 hours more (1.5 full recharges)
iPod nano: 4 full recharges!
iPod shuffle : 60 hours more , 5 full recharges!


This project is suitable for beginners, some soldering tools are necessary but even if you've never soldered before it should be pretty easy.
