Hey All,

It's that time of the year, late christmas gifts (actually the three kings in Spain tomorrow!). Need to build a setup for my mother with 1000€.

The PC will be used as a work rig for PhotoShop editing (adobe suite in general), Sketchup, Fusion360 and maybe some CAD.

Don't wanna fanboy but I've used Intel and Nvidia my whole life, don't mind trying Ryzen and I have selected a Ryzen 5 3600.

Regarding the monitor, allocated 300€ to that. IPS and 27" or more is a must, haven't found much better than the BenQ GW2765HT 27".

Here's the config I've selected so far. If there's a  better alternative using Intel/Nvidia please let me know. Thanks!

Sounds like you're not at this stage yet but any thought as to how you'll get it in orbit?  balloons are great for going straight up but the stuff they carry tends to come straight back down after they pop

Looking back at this message makes me laugh hehe, can't believe we went from this to launching on an ICBM style rocket

1 week working in space   Think this thread is a good demonstration of how projects evolve and can actually be made a reality.

Working on the next ones for launch in March now.

Hey man, this is sooo cool. I'm just wondering, was  your sattelite on the 'Look Ma, No Hands' Electron rocket? The one that launched on the 19th of august?

 

If so, i just watched it and it was really cool

Hey! We just integrated the satellite two days ago, we should be on one of the next electron launches this year. Here are a couple pics of the last months which has ben full of testing at vibration, thermovac, emc facilites etc. lots of work but its all done! our twitter @fossasys has everything updated

Launch window now August 1st to 31st from RocketLabs Electron rocket!

GoFundme campaign is up here: https://www.gofundme.com/manage/fossasat1-la-democratizacion-del-espacio/ 

And here is the explanation video:

Congrats!  The satellite I worked on just went up on that last Rocket Labs launch!  Good luck with the remaining hurdles!

Great Stuff! We are number 8 for launch in q3 of 2019.

This sounds like a great project and I would love to see it get off the ground and into space.

Thanks!

I did something very similar using just BC547 transistors.

Pretty easy to do! Final satellite does not use it but it's a cool concept.

Have not updated anything on here for a while! Orbital launch has been signed with Rocket Labs, we are set to launch in Q3 of 2019 into a 385km SSO orbit. We will most likely create a kickstarter in the coming months in order to fund the remaining launch costs, keep an eye out

Monthly Blogs on https://fossa.systems/blog/

Gave the talk along with a workshop on open source aerospace missions at the European Space Agency, We are having future meetings with them and a couple universities so it seems there is general interest! The engineering model is finished with deployable solar panels and will be launching this week on a weather balloon to test the telecommunications.

Funny to think this time last year we where joking around on launching and now We are a couple weeks away from launching a launch contract with a major launch provider

To any newcomers here, this was a leaked sex tape between Luke and Linus. (Linus has a secondary channel on P***hub for this sort of stuff. ) Don't get too excited though because all they do is eat c**ks.

Those pcbs are so cool.Hope you could succeed.

Thanks Nicholas! European Space agency talk is on Monday and we are close to signing a launch for summer of 2019. Seems amazing how we went from a little PCB designed on Sunday evening to a working prototype possibly going to space, I would have never imagined that this would have ever grown to where it is now 

We are still looking for help by the way!

I'll keep you guys informed. Thanks,

Julian

N9KUB Here. 

 

Got my Technician license here in the US back in the early 90's, when it was a brand new thing. Took the test on a dare when visiting a friend on the weekend he happened to be taking one of the higher level exams. My college degree was in electronics so they figured I should be able to pass the first couple tests. I almost passed the one after Tech.

 

Had a Yaesu handie talkie for a couple years, but never got all that involved. Haven't done any HAM stuff since the mid 90's.

Ah nice, seems like the exams are pretty easy to pass with common electronics knowledge. Finally got my Callsign: EA4HCD, don't plan on doing much HAM stuff but at least now I can start coordinating our satellite with the IARU!

Ah great, You can build cheap tape measure antennas with around 13dbi of gain.

I got one of those about two months ago (Nooelec) and it fried itself, as others had said happened to them. I figured that more expensive forms would be needed to get something "decent" so I dropped it. My intention was for radio astronomy however and not listening to radio communications. (i.e. mapping the hydrogen gas in our galaxy)

 

I'm not entirely sure if asking about alternatives is exactly on-topic, but I suppose it's relevant to the general subject of "amateur radio"?

Wow, I'll be honest I have never heard of mapping the hydrogen gas in our galaxy but it sounds interesting. I can probably guess that a 10$ has nowhere near the sensibility needed to do that. You'd probably need something more precise like a LimeSDR or an XTRX. I can also imagine you need to be quite far from civilization to pick up those radio waves.

Yep I'm a HAM Operator, only have a foundation licence. my call sign is MW3IHX had my licence for ages 

Ah nice, do you ever transmit?

Just passed the exam, pretty damn weird questions but since its multiple choice and you only need to get 50% right then it was an easy pass.

Waiting for my callsign rn and I have been told I need to set up an amateur radio association..... More paperwork!

I really cannot afford the gear, but I listen to number stations through webSDR

http://websdr.ewi.utwente.nl:8901/

 

A station out of the Netherlands. Wish I could get a good setup in physical form, but the 'net software version does for me now.

I also love hearing things like German disco, or the BBC

Thankfully nowadays you can pick stuff up with a 10$ USB SDR and a diy tape yagi, these sdr websites are great though and I have used them too besides my home setup.

I didn't actually have the intention of doing anything related to amateurs communication since the only reason I am getting the exam is to request a license from the IARU to launch a picosatellite project in orbit, it seems really interesting and fascination though and I'm sure I could get some stuff to work with my current setup.

We have the option here to do CEPT HAREC  and so do overseas visitors. 

 

That station location is where I was born!

 

The more you know  

 

 

Ah, we only have the HAREC option, its a universal pass to all the bands at every level.

Interesting haha!

Awesome mate!

 

I have been meaning to do the exam for yonks now but just haven't gotten around to it.

 

Let me know how you go!

 

 Cheers,

Thanks mate!

Here in Spain its the HAREC exam, not sure if Australia has adopted the CEPT 61-02 recommendation but if so I think its the same exam, I'm no RF expert and just did the online test questions today, seems to be common sense electronics to be honest.

Hopefully its as easy as they say it is!

Thanks mate

Was Just wondering if there where any HAM radio Operators out there on the LTT forum, Seems like the mean age is slightly higher than that of the forum but who knows!

At least in europe it looks like it is slowly fading away.

My Exam is in 7 hours, hopefully a pass....

Thanks!

There is no way of making a workable machine for that budget in 2018... sorry. The lowest I would consider is the Tronxy X1 kit at about ~$150 once you buy a spool of filament to use on it.

I can personally say this is not the case, I can't post ebay links on here but this 100$ 3D printer I bought performs better than 300$+ 3d printers I have used with proper calibration and tuning.

Prints look great and it is well worth it just for parts tbh, In Spain these cost 92~$ shipped with UPS to your house free.

Where you do place your laptop? 

I just bought a CTC anet a8 styel printer for 100€ works like a charm with heated bed, dont get me wrong it takes 2 years to calibrate properly but the prints are well worth the cost.

These geniuses used an AC inverter in order to turn DC into AC so that they can convert the AC back into DC.

 

Then they use a relay to turn the power on and off which completely negates the need of the generator powering the switch.

 

Wow. I admit I am quite impressed with how bad this was.

I Agree, simplest would have been direct 12v into the switch or a sensor such as an Arduino connected to the pc or a relay.

Just use a sensor to turn on the network switch after a certain voltage is reached......
