BinarySpace HAB Launch – Binary – 04 – 4 Aug 2018

Hi Everybody,

We are doing another High Altitude Balloon Launch on the 4th of August (Saturday). Everybody is invited to join us for the day to launch and chase the balloon. We will be launching from the NWU Vaal Triangle Campus in Vanderbijlpark

This launch is all about the data, we have a multitude of sensors connected to a Lora blackbox that will both log and transmit the data during the flight.

The flight prediction for this flight a bit rough and indicates that the balloon will come down about 220km from the launch site. We are hoping to bring the payload down a bit earlier with our payload seperation system. If the failsafe fails then we have a bit more driving to do. The main chase vehicles can also be tracked on aprs (ZR6TG, ZS6MDV and ZR6MUG)

The SSTV camera was popular last time and we are flying it again, this time with a better bracket to hold the camera in place (so hopefully less transmitted images of the inside of the payload). QSL cards will be sent to all radio amateur participants that receive and decode SSTV images. The SSTV camera will point outward and we are hoping for some great views.

Our gopro for this launch will be pointing upwards to the balloon for this one as we want footage of the payload release system, or if that fails of the balloon bursting.

This launch will also contain 3 additional third party payloads:

– MakerLabs Science Payload – Various sensors that will be logged. (http://makerlabs.co.za/)
– Matthew Varkevisser – ZS6MDV – Parrot Repeater listening on 145.525 and is activated with a 88.5hz tone
– Michael Bernhardt – ZR6MUG – GoPro + ZCoin Logo

About the Mission – Binary 04

Equipment on this flight:

SSTV Camera Transmitter (400mW-500mW) – Will take a photo and transmit it every 5 minutes.
Transmitted on 144.500 FM, Martin 1 Mode
You can use MMSSTV to decode (http://hamsoft.ca/pages/mmsstv.php)

Lora BlackBox Telemetry Transmitter (100mW) – Will transmit telemetry data continuously

Sensors include pressure, temperature (inside, outside), humidity, gps. All data will also be logged locally on sd card for retrieval

APRS Transmitter (300mW) – Will transmit position and altitude every minute

Technical Info:
Callsign: ZR6TG-11
Transmitted on 144.800
You can follow on https://aprs.fi/#!call=ZR6TG-11&timerange=3600&tail=3600

We will also have the following on the payload:

1x Gopro camera
1x Science Lab (Raspberry pi based with lots of sensors) designed and deployed by https://www.pishop.co.za
1x Payload Seperation Fail Safe
1x Data Blackbox

Sasolburg Amateur Radio Club (ZS4SRK) will join us with the tracking and recovery of the payload. As usual all amateur radio enthusiasts everywhere are invited to come play with us 🙂

Please also share to any Amateur Radio Groups/Clubs
We are using a 1000g balloon (white). We are estimating a 3 hour mission from launch to recovery.

We have the following challenges happening during the launch:

(1) First person to recover the payload gets a box of craft beer (from http://www.degarve.co.za)
(2) Footage of the Payload coming down will be rewarded with 1 box of craft beer (from http://www.degarve.co.za)
(3) Special Awards (QSL Cards) will be given to everyone who captures the SSTV images. Please mail tvdbon@gmail with the decoded information, time of transmission (bonus if you can provide a recorded sound clip) and your location and equipment used (optional)

Primary launch window: August 4 2018 – 7:00 (we start setting up somewhere around 6:15)

Depending on weather or technical difficulties the launch and/or the payload contents can change at any time, check the telegram group for up to date information:

Ham,Pi and a 3d printed Lawnmower… (Meetups February 2015)

I’m long overdue on a meetup update so here is a nice big post with things you might have missed the past month at BinarySpace:

Gary Immelman came to the space to give as an introduction into Amateur Ham Radio. It doesn’t take long to see that Gary is a very successful and passionate Ham Radio operator. He told us some very cool stories of his electronic and radio adventures. The people he has communicated with (even the Astronaut that came to dinner after a chat they had over the airwaves).

Amateur Radio covers so many aspects and there is lots of toys to play and experiment with.DSC_5088 (Large)

 

It was a very interesting talk and inspired a few of the members (including myself and Michael) to start studying for the Amateur radio license exams happening in May.

We had a 3d printer themed evening with local ‘large scale’ 3d printing guru Hans Fouche as a guest. He brought along lots of 3d printed goodies including printed shoes, a vacuum cleaner and a 3d printed lawn mower.

Hans shared a few of his successes and failures (not a lot really) in his 3d printing adventures. If you haven’t heard or seen the 3d printed lawn mower in action then surely your living underneath a rock. It’s all over the interwebs!

Also  check out the 3d printer that Hans built, it’s called the Cheetah, it’s fast, large and it’s awesome!

I’ve also showed off my scaled up 3d printed 3d racers.

Between all the meetups and hacking we have also been hard at work at improving the space. It recently got painted, were adding more work space, shelves for various hacks, projects and our beer glass collection. A new keg system is up and running. It’s still a work in progress but it’s getting better and better every week. Thanks to everyone who helped out and all the donations we have received.DSC_5190 (Large) DSC_5191 (Large) DSC_5197 (Large)

 

Between all of this we still found time to check out the new Raspberry PI 2, work on our HAB project and build some Arduino game goodness:DSC_5173 DSC_5201 (Large) DSC_5196 (Large)

 

We also have a few new regular members. Welcome and we hope you have fun!

Lots of other projects also happening, but sometimes I’m just having so much fun that I forget to take pictures, so sorry if I missed something. But then again, if you attend the meetups you won’t miss anything 😉 Also, check out the project page for all current and future projects.

Until next time 🙂

This week at BinarySpace – 15 May 2014

We had another great meetup this week. This has been the second week that we’ve been playing the with stm32 discovery kits. Everybody is up and running and we’re learning new things every time. This week everybody got some ttl-usb converters and got the uart working on the devkits.DSC_7076.resized DSC_7078.resized

Marnus played around with a RaspberryPI and relay board. He is working on a home automation project.

Sebastian continued working on the power monitor project (PowerHome), he is currently busy setting up the spi comms to the power monitor devkit.

We also spent a good portion of the time stripping this Sunix server from about 10 years ago, it was not working before we started. It was pretty cool pulling out the 16mb ram modules. It’s a stunning case though and this will be converted into a server case of some sorts. There is space for more than 20 hard drives in the front!

Our stm32 learning efforts are all being commited to our github repository which you can find at https://github.com/BinarySpace-Hackerspace/stm32tuts, this includes the nokia lcd 5510 example seen below with Bender!

DSC_7097.resizedTill next week and Happy Hacking!!
