  1. Building a satellite

    Thanks for the feedback, I will look into making each side a ground and power plane. On the topic of batteries, I have considered using an array of capacitors for short-term storage of electricity. The idea is also to use a launch device that launches it with the panels facing away from earth. What would be a way of confirming the satellite has been deployed? Something like an accelerometer could do the trick?
  2. Building a satellite

    Oh ok! I have it now, will modify the PCB later.
  3. Building a satellite

    Unfortunately no, Im looking for a schematic with the traces from the atmega to the 3 pin crystal since I believe one of the pins is connected to ground or something like that.
  4. Building a satellite

    I have not ordered the pcb yet and just wanted to make sure, my only concern is that I am using this smd crystal and it has 3 pins, looking at my arduino nano on my table it seems like its wired up differently. However I cannot find a schematic of the arduino nano. As far as the SPI pins are concerned I just followed the schematic and as long as it works I dont have any issues with it. For now the camera idea is set aside due to power restrictions, however when I do come to it I have already started thinking about cycling the components and having sleep periods etc. And for directional purposes I considered electromagnets but they are irrelevant on this scale of a satellite, thus the dual sided solar panels.
  5. Building a satellite

    So I just finished designing a first version which I do believe is full of issues (obviously being my first pcb) Due to legal issues and ease I have decided to use a 433mhz tX based on a 433mhz resonator. This PCB does not have sensors right now and relies on a 4v 100ma 30mm x 70mm silicon Solar panel which I managed to find for cheap. I also believe the 16mhz crystal is not wired correctly and Tbh if anyone could just give it a check if would be nice. Anyways here are the pics of the PCB and the parts: It is based off these schematics U1 - ATMEGA 328P-AU U2 - 0.1 uf Cer U4 - 22pf Cer U5 - 22pf Cer U6 - U7 - 1k R U8 - XC6206P332MR U9 - S8050 U10 - 2SC5537 U11 - 1uf cer U12 - 433mhz resonator U13 - 7pf Cer U14 1uf cer C1 - 7pf C2- 47Uf R3 - 20K R4 - 27k Any help on checking this pcb would be greatly appreciated. @ShredBird @ionbasa
  6. Building a satellite

    Yeah it was indeed a 18650 and I did start experimenting with nichrome wire to warm the battery when on the "cold" side. However, on this satellite, I will not be going to use a battery and it will be purely relying on the regulated voltage from the gallium arsenide cells. Oh and thanks for the support!
  7. Bypass Remote desktop FSX

    Im currently trying to run FSX on a remote desktop to host a server but it says "Flight simulator is unable to run on a remote desktop" is there any way to bypass this or host an fsx server without fsx haha. Im running fsx steam edition and im not planning on using it to game just to host just to clear that up. The Server has 2gb of ram and an SSD so I think it should do fine.
  8. So my friend is looking for a BASIC video editing (Windows movie maker and Camtasia etc) and school work laptop. His budget is more or less 320€, I know buying used is cheaper and 300€ is a very low budget but he needs it as soon as possible and he does not want anything used. Here are the pages we use here in Spain: https://tiendas.mediamarkt.es/portatiles-medianos/ct/memoria-ram-gb.8?orderBy=price&orderByDirection=ASC https://www.pccomponentes.com/portatiles I also found this: https://tiendas.mediamarkt.es/p/portatil-lenovo-ideapad-320-15isk-15.6-hd-1383011 Thanks, Help is really aprecciated!
  9. Building a satellite

    Yeah I found a company that sells gallium arsenide sells by individual cell and they seem to be cheaper. Worst case scenario I found some sketchy gallium arsenide cells on aliexpress that could work. Yeah its a great project! Definitely very fun! And the satellite cost is indeed low compared to the launch.
  10. Building a satellite

    Unfortunately, EMCORE sold their photovoltaic company 2 years ago and looking at other companies like SolAero they seem to have 7,500$ minimum orders.....
  11. Building a satellite

    Thanks a ton I'll contact emcore asap and take a look at the book
  12. Building a satellite

    Hey ShredBird, Thanks, the support is really appreciated and I will definitely need some help when it comes to wiring everything up especially since I'm planning to design a voltage regulator circuit for the solar panels and I might need help with hooking up the camera FIFO for sstv (similar to a buck converter). As far as the tips you mentioned above here are a couple of things I'm doing and let me know if there's anything I can improve on. 1. I'm still deciding on the parts but most likely 6cm x 6cm PCB with 1 solar cell on each side, A temperature sensor, an accelerometer and an SSTV camera. 2. I still need to see whether there is a remote possibility of launching this thing on its own but Most likely will need a 1U mothership for launch, that's a whole other project haha. As far as power budget I have a spreadsheet with how much current every single component will draw and the smallest gallium arsenide solar panel I can find (with a slight current headroom) And as far as telemetry I'm also making a list of each set of data im sending and the lowest power consumption / Mw needed to send them. 3. I decided on not using deployable solar panels since it would add too much complexity and be too fragile on such a tiny satellite. 4. I actually did not know that about lead, thanks! I'll make sure to solder the components on with lead-free solder. 5. I definitely agree with this one, Building a satellite involves so many areas of engineering and is a great possibility to learn. Also since you seem to be experienced in this do you know where I could get gallium arsenide solar panels, I have contacted some suppliers but I'm still waiting for a response.
  13. Building a satellite

    Yeah, the top third will house the components and the bottom will be all solar panels. The PCB will be much more crowded once I add the communication components and sensors
  14. Building a satellite

    That's some pretty good ideas you have there, I'm currently looking at some forums for some partners! Update: I have started creating the PCB's and have ordered some of the SMD components. I have also started making some of the code for the voice telemetry system since this satellite will probably have a voice telemetry system. (The pcb's are missing most of the parts)
  15. Building a satellite

    yeah, I meant storage, my bad.
