Im pretty sure I saw a camera on the ground filiming it and they just cut it off a couple seconds before touchdown edit: apparently cameras fail wth vibrations

that moment when the core engine crashes on landing

I KNIOW RIGHT; HOPEFULLY THE BOOSTERS DO ON LANDING

well, space is black so i think its a multicultural launch.

Im guessing 2 million at t-1m

As long as temps are not high, I remember mining with my gtx 660 for months non stop and I never had issues

The total weight will be around 80g with the balloon

I have been checking the laws for this in Spain and its fairly easy, if done legally you just need to fill in some forms and request an airspace reservation. However, with this thing weighing well under 50g I doubt it will even need to be done.

Thanks, SMD parts are ordered and I'm just finishing up the PCB before I send it for manufacturing. Unfortunately, 2 of the chips I'm using are bga but i'll have over 10 boards to practice so I think I'll be fine. I have also tested an Arduino mini pro with some breakout boards for the components I'm using and I have managed to get Text to speech working to transmit data, currently working on setting up RTTY transmissions. I tested the small 433mhz tx and it seems to work as far as I have been able to test it line of sight. However, as soon as I test the pcb I will change the transmitter to something more efficient and powerful like an RFM22. Just having trouble again with the solar panels......

Open vagin, insert bob

First come first serve, just random games worth 5c-10$

Short update since I have not posted in a while! I received the magnetometer, accelerometer, barometric and temperature sensor. I also received a sponsor from pcbway for the pcb's themselves which is nice. I also found a solar panel provider and have received some samples even though they are supposed to send more after CES. Im currently busy programming the code with an arduino nano, integrating the sensors into the pcb and will soon order a rework station since the pcb is fully composed SMD and BGA chips.

Notice the hand print in the background hahahahah, is this one fo thos 150~$ anet a8?

Yeah I was indeed thinking about the attitude control and instead of using electromagnets just static neodymium magnets would work. Is there any previous examples of this being used before? And would it be more beneficiary to use large capacitors for short term storage or smoothing or to use small rechargeable cells for when entering the dark side. I also think a magnetometer could be a useful to figure out the current orientation of the craft. Yes that is true, maybe I could combine the radio antenna with the separation wire or use a very thin copper wire.

Any updates?

I will look into the capacitors, I think I will use the accelerometer anyways for monitoring purposes. I wont use GPS since its very challenging to get the appropriate certifications for launching. Theoretically you could use the wire as a switch and then maybe even use it as your radio antenna if it had a specific breaking point for that frequency, However I believe the accelerometer is a more extensive and precise way to measure the launch without any "External" and mechanical components.

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?

Oh ok! I have it now, will modify the PCB later.

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.

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.

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

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!

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.

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!

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.
