Techie Night October 27, 2015

Please join us for Techie Night:

7:00 PM

East Plains United Church
Classrooms 10 / 11
375 Plains Rd East
Burlington, On

 

We will be working on constructing a multimeter RF Probe project  (I have 10 kits available).  This RF probe is fairly easy to construct and useful to measure and detect RF voltages in the range of 0.25v to 50v at frequencies from DC thru 30mHz.  The probe is designed to plug into a multimeter with an impedance of either 10MΩ or 11MΩ.  Please feel free to bring your own soldering irons, soldering gear.

We we will also be providing free programming clinic for Baofeng / Wouxun Handy Talkies.  Would you like your radio to be setup with it’s optimal settings? Would you like your memory channels populated with local repeater frequencies/CTCSS tones? Weatheradio(NOAA) Weather Frequencies (NoTX)? MURS, FRS, GMRS, or Maritime VHF (for TX must have ROC-M or ROC-MC)?

Techie Night, August 18, 2015

Please join us at the East Plains United Church at 7:00pm on Tuesday, August 18th for Techie Night.  Our meeting will be held in classrooms 10/11.  A Google Map showing the Church’s location can be found here: https://goo.gl/22UJTI

Tonight’s meeting will be a demonstration and discussion of remote radio receivers and transceivers available on the internet.  There is a variety of radios available online which we can remotely control.  These radios are located all over the world and have a variety of features, band capabilities and modes.  As well as entertainment, these remote radios have a lot of other applications which are very useful to us as amateur radio operators.  We will explore web based, computer based, and mobile based applications which allow control of these radios.

As always, please feel free to bring along any nifty new (or old) technology you think would be interesting to discuss with the group. 

We had a few contributions to Big Box of Parts last week.  For those who are not aware, the Big Box of Parts (BBoP) is a community junk box which we have started for Techie Night.  BBoP will be at each Techie Night, so if you are looking for a part to finish a project or as inspiration to start a new project, have a look in the BBoP.

It has been incredibly hot and humid over the past few days and if it is still unbearably hot, we may want to consider moving the meeting over to the air conditioned Tim Horton’s across the street.  We’ll meet in the parking lot and make a judgement call from there 🙂

 Stay cool!

Techie Night August 11, 2015

Please join us at the East Plains United Church at 7:00pm on Tuesday, August 11th for a social evening of open discussion, show and tell and the introduction of the BBoP.  The meeting will be held in classrooms 10/11.  A Google Map showing the Church’s location can be found here: https://goo.gl/22UJTI

Tonight’s meeting will be an open forum to show off and discuss your latest gadgets and projects.  Please bring along any project(s) you have been working on or any new exciting gadgets you have acquired this summer and share your experiences with the group.

I thought it might be interesting and beneficial to try starting a Big Box of Parts program for Techie Night.  This activity is very popular amongst a number of the online electronics experimenter communities.  The activity, usually called ‘Big Box of Parts’ (BBoP) is a box of shared parts which is circulated amongst community members who give and take freely (and fairly) from the box.  This idea is thought to have started out in the DIY Audio community online, but I think it most likely has its roots in amateur radio.  A lot of us already do this informally on a one-to-one basis, freely sharing parts we have in our junkboxes with each other.  I was thinking we could do something like this for Techie Night and make the ‘Box’ available at each of our meetings.  This could really turn out to be a lot of fun!  It might even come to the rescue one day…for that project you’ve been working on… which has been missing that impossible to find part!  It might even provide that spark of imagination and inspiration for your next project.  I think the most useful aspect of this activity is it can assist us all in learning about and using parts which we may not have had the opportunity to work with before.  I also think this is an activity which provides an opportunity to Elmer and share tips and tricks.  The only difference between the online community version and ours would be that we wount be shipping the box around member to member…it would be available at each Techie Night meeting and available upon request outside of Techie Night’s.

Usually a set of gentleman’s guidelines are kept in mind to keep things fair:

– Take parts out you can really can use

– Replace them with parts you may have extras of, can’t use or wont use (please try to give back an equal amount of stuff if you can … if not, not a problem, try to give back something when you can)

– In the spirit of education and sharing, if you are able to, please send Paul Stuart a picture and a description of what you got out of the box and how you were able to put it to use (i.e. education, project, prototype, repair, experiment, etc.).  It would be great to build an area on the website in the Techie Night Section about the Box of Parts, displaying some of the picture and stories of how members have benefited by this activity.

– If you come across something interesting and you have an extra, or a part you know you probably wont use, but think someone might, please consider donating it to the Box

– Please don’t add items which are not relevant to electronics or amateur radio

I’ll seed the box with some items and if you feel you have some parts to contribute or swap, please bring them along to help get this started.  Hopefully this takes off and is something we can all benefit from.

Look forward to seeing everyone able to make it out this evening!

Techie Night August 4, 2015, AllStar Link

allstarlink-what-is-it-for-ham-radio-1-638

Please join us at the East Plains United Church at 7:00pm on Tuesday, August 4th for an evening focused around AllStar Link.  The meeting will be held in classrooms 10/11.  A Google Map showing the Church’s location can be found here: https://goo.gl/22UJTI

The AllStar Link network consists of a number of individuals and large (and small) groups of like minded amateur radio operators who wish to provide efficient large-area communications to the Amateur Radio public in their respective local areas. This is done by providing a local VHF or UHF repeater system controlled by a Linux-based computer system running the open-source Asterisk PBX telephone switch platform along with the app_rpt repeater/remote base controller/linking software module connected to a high speed (broadband, such as Cable Modem or DSL) Internet connection.  Building personal repeaters/controllers/bases is also encouraged.

The computer system running Linux/Asterisk coupled with the app_rpt module makes for a powerful repeater/remote base controller capable of controlling many (like up to hundreds, theoretically) repeaters and/or remote bases per computer system. It provides linking of these repeater and remote base “nodes”, with “nodes” on other systems of similar construction anywhere in the world, over the Internet via its IAX2 Voice Over IP protocol. It also, of course, provides for an Autopatch (public switched telephone network access over the radio) on each node (Asterisk is a phone switch after all J), if desired.

The requirements for building your own platform are very modest and require a low cost PC, a USB sound card fob and a 2m or 70cm radio, some soldering if you wish to make your own interface and some time to configure and fine tune the software.

Please join us on Tuesday evening to learn more about AllStar Link.

Look forward to seeing everyone able to make it out!

March 17th and Techie Night

JpegP1030172

The program started off with two guest speakers from Access 2 Networks. Jeremiah teaches computers and programming at Sheridan in his spare time. Patrick’s main hobby is building with micro processors and teams up with Jeremiah on projects… at present they are building a 3D plotter for PC boards and also fabricate their own boxes with a 3D fiber printer.

JpegP1030176

Patrick showed his Arduino micro processor he fitted into a USB housing. Wow! He just inserts it into the PC USB port and programs it. See photos. Also, his Raspberry PI 2 and some projects using them. Jeremiah demonstrated various ways to make PC boards with samples he made. He brought also supplies he used.

It was a very informative evening with a lot of interest.
