New tracker PCB in detail

This is the first time we go all the way down the road, from the breadboard to the final PCB small production run.

This article shares some pictures of the process we went thru to get our custom tracker!

Well, it all starts with a layout form Eagle (this one is available form our GitHub Repository).
v1

When the layout is ready, Gerber files are sent to a PCB house (we’ve used hackvana).

pcb step2

Once the PCBs arrive, it’s time to check every detail, place the components on the PCB, check if everything fits and place it in the fixture block, as pictured below.The new tracker pcb has arrived - Balua Project

pcb step3_2

In the picture above the PCB lays on a Stencil8 alike fixture block, ours was made using a piece of acrylic laying around the workshop instead of solid aluminium, but works fine!!

pcb step4

This fixture block and tooling pins are crucial to get a perfect alignment  between the PCB and the stencil.

Next step is simple, spread solder paste and pick&place (by hand) every single component. Put it in the reflow oven for 10 minutes and it’s done!

This is the result! Isn’t it beautiful?

New article in Exame Informática

There is a new article in Exame Informática about Balua and our latest launch in Évora, Portugal.

The title of the article is “Engineers from IST launched an high altitude balloon to communicate with all of the Iberian Peninsula” . The online version of the article can be found here (in Portuguese) and it is an excellent description of our concept and the work developed in that launch.

Tracker Launch wrap up – Success

Yesterday was an awesome day for Us!

1º – Our new tracker worked flawlessly during the flight (aside not reaching any igate except our chasing car during a very fast descent!)

2º – The very experimental cross-band repeater almost  reached the entire Iberian peninsula and was very busy with QSOs from Cascais(PT), Algarve (PT), Entroncamento (PT) to Cordoba (ES), Villacarrillo (ES), Gibraltar (ES). Balua’s CR6BAL repeater was definitely a huge success! Something to improve and build on!

3º – Balua’s payload landed in Spain, few hundred meters from the Portuguese border, north of Badajoz (ES). The recovery was nice and easy with a helping hand from the land owners!

4º – Last but not least, this day was a better day thanks AMRAD (very busy as well hosting a great field day) and LARS. Thank you all!
