  1. Are you using Wifi or ethernet? if you are all on the same network then probably your network card is limiting you
  2. Asked them for a refund on a product that was crap and they denied.
  3. I guess you can always make your own installation disk if you had a compatible floppy reader/writer with a more modern system
  4. If its not a GPU or a CPU, its a mobo bridge, probably for IO. Is there a number on it?
  5. Thanks mate, if we actually get this up in orbit and it works I will be quite happy (aka shit my pants) Just a lot of designing and maths for the moment but I'll make sure to keep you guys updated!
  6. For anyone else still reading, We are starting to receive funding from Sponsors to hopefully reach our goal of 25k, We have nearly finished manufacturing our engineering model and the software aspect of things are done thanks to our software engineer. We will go to a satellite conference in the Europan Space agency Astronomy Center this September to show off our satellite and hopefully find some contacts, Hopefully we get administrative stuff moving to start requesting launch approval and frequency coordination from the International Telecommunications Union.
  7. Quick update for anyone still reading these. The team has been established and prototype development is already in progress, an open source github repo is up at https://github.com/juliantech5/FossaSat & https://github.com/FOSSA-Systems A webpage is up at fossa.systems , more info can be found on there but it's still missing a lot of details though most frequent updates will be posted on there. Thanks!
  8. Looking for people to help out (Read below) Been a while since the last update but a lot of stuff has happened, mainly research and contacting people. There is a lot of stuff to explain but summarized as much as I can, I changed over the mother ship architecture to a pocketqube (5x5x5cm) and contacted a bunch of people who worked on previous satellites and companies for possible authorizations. Long boring text ahead explaining in detail: Realistically if we want to get something up in space we need to launch it using a standardized formfactor, the most common picosatellite formfactor is the cubesat (10x10x10cm) but recently the pocketqube has gained popularity since it is currently the smallest launchable formfactor. Therefore our small sprites will be launched from the pocketqube mothership. So, now I had that in mind, I wanted to see just how far this could be theoretically taken. So here is the long boring process of emailing a bunch of people. But in summary I contacted Alba orbital and Gauss that quoted me 25k for the launch and 16k for the launch respectively (Q4 - 2019), these launches are currently purely theoretical until there is a working prototype built and funding is another issue but I could invest some money in making a crowdfunding campaign though once again this is purely theoretical, right now the focus is finishing a prototype by november. I also got in contact with Stuart from the 50$ sat to discuss some issues with RF. Solar cell provider has also been found (Trisolx) and they can supply triple junction gallium arsenide cells. Ultimately I am in contact with Tom (CEO Alba Orbital) discussing the approval issues with launching such small satellites from a pocketqube, will hopefully be contacting people soon to see if we can actually launch 2x2x0.2cm boards from a 5x5x5cm satellite. The radio protocol we will be using is LoRa due to its low power consumption and long range, it can also be picked up with 20$ worth of parts. This is the current to do list in the next month. - Pass my HAM amateur radio operator license (needed to transmit to satellite for tests etc) - Sort out the regulations involved with launching sprites - Design MPPT/Power management board (Looking for people to help, simple circuit design to check my work) - Start working on the code for the satellite (Looking for people to help here too, couple things to work out) - Design pocketqube frame and deploy mechanism (Start looking for CNC workshops that can mill the part) That's it for now, seem like its really advanced from the beginning and I cant wait to start working on a prototype, research & design for now!
  9. Possibly an issue with the motherboard causing a short circuit, is the psu tested with other motherboards?
  10. Well considering this post is 2 years old and the OP is not active, I doubt you will get a reply.
  11. works great! its a ctc 3d printerb so basically a geetech i3 clone, prints with great quality after adding a cooling fan and some reinforcments, honestly the best deal I have ever made!
  12. Lil Update: Apparently its arriving tomorrow based off the UPS tracking number, seems legit
  13. New platform usually involves a CPU, Motherboard and sometimes ram upgrade, I would consider that a new PC.
  14. I mean for 99€ anything that works is a good deal, ill def post it in the tech deals if its true. The previous model I bought had quality comparable to a makerbot if well tuned with 3d printed supports and cooling fans.
  15. I mean I payed 160€ for the same model a year ago and the parts are probably worth less than 50€ its just a bunch of motors and an arduino. Worst case scenario, Ebay always helps the customer.
  16. Welp guess I'll tell you if it was a scam or not in 10 days.
  17. I dont personally know much about Lubuntu but I have used Xubuntu on laptops with 1gb of ram no problem, Honestly whatever the OP prefers since they seem to be similar OS's
  18. So I just saw this ad on ebay https://www.ebay.es/itm/282940521154#shpCntId, its a a prusa i3 printer for 99€ from Germany?!?!?!?!? I recently bought the same model for 160€ about a year go but 99€ seems too good to be true. I mean with ebay and paypal theres not much to be lost?
  19. Buy some used deep charge batteries and solar panels, for 100$ you cant do much.
  20. The original software is native to W95 so I would recommend XP or earlier, Good luck!
  21. impressive range for an internal antenna!
  22. What antenna are you using?
