Antenna Build Day

Come join Makerlabs on a our antenna skill building day. During the course we will cover basic antenna theory, build and test a high gain 5.8 GHz antenna suitable for FPV analog video. The course will start at 9:00 and we aim to finish at 14:00.
In this course, you will
  • Receive a presentation on basic antenna theory (radio frequency propagation, impedance matching, coupler, filters, radiation patterns, gain etc)
  • Build your own high gain dish mountable 5.8 GHz antenna (ideal for long range analog video) – complete with SMA connector and coax, ready to use (all material supplied as part of the course)
  • Test the performance of your antenna by measuring the reflection and end-to-end transfer using a transmitter/receiver circuit
  • Compare the performance of your antenna with other designs, like a patch and clover leaf antenna
The course will be valuable for FPV pilots and hobbiest who would like to learn more about the dark art of RF and how to maximize the performance of their existing equipment.
Cost: R650 per person
Date & Time: 08 April 2017, starting at 9:00 until 14:00
Venue: Made In Workshop, 65 Maria Street, Fonteinebleau, Randburg


Last Nights Meetup – 30/04/14

This week was a bit of a lean meetup as a few of the projects have hit a spot of testing and debugging. So i’ve thrown in on our bottling experience from last Saturday during the braai.
Matt received his fpv head gear on Wednesday. He got it all wired up and transmitting. Looked pretty sick.
I removed the temp sensor from the reflow oven as we were getting some bad readings.
Once removed it worked perfectly so we will need to figure out what’s causing the problem when mounted in the oven.
Replaced the relay with one that works with 5v so I no longer need to move it around with a 12v bench power supply.
Lee came around for a chat. showed some cubie boards off. didnt have a screen for him to demo what he’s been working on
I turned beers we had bottled the week before to suspend the the priming sugar particles.
Marcel hacked away at get linuxcnc to connect to the cnc electronics. It seems that the usb port on the controller board is just for show and we will need to connect to it via the parallel port/
Marks nearly finished up soldering his kit board and should light it up next week.
Matt generously donated a pack of hot dogs and some rolls for the evening. more than enough to go around leaving a couple for Einstein to munch.
Bottling of the beer:
Saturday marked the first bottling of the beer. It was really successful and we managed to get 50 clear bottles of beer out of the fermenter.
We kicked the day off by sanitizing 25L of water to sanitize the bottles and caps that will be used for the day.
Matt prepared the peristaltic pump by sterilising the pipe and running a few test fills with the sanitized water.
We then started sanitizing bottles, emptying them and adding priming sugar.

Filling them to 400ml and lining them up on the table ready for capping

The siphon tube place in just deep enough to not suck up the sediment that’s settled at the bottom of the bucket.

We then capped each one with a sterilized cap using the 2 handed capper which can be quite finicky.

Once I had then all capped cleaned up and put them aside to to start their final step before they can be drank, carbonation.

What’s in store for the next meetup:

Working on a pneumatic bottle capper to save time on capping all those bottles.

Reflow oven tests

Marcel will be starting his 3d printer build.

See if we can connect linuxcnc to a pc that has a parallel port.

Till next time…

Happy Hacking!
