Richardson Wireless Klub invites DMS - Call for Help

[bpamplin]

RWK, the amateur radio club in Richardson has invited me to do the presentation at the March meeting. The topic will move from Introduction to Arduino to Microcontroller Projects in Amateur Radio. It will include slides on DMS and our classes.

I would like to include slides on projects by DMS members. If you have a related project that you would like included, please send a short description and a photograph. We will have a couple tables set up and with demos and projects to show during the break and after the meeting. You are welcome to join and brag about your work. The date is March 11. I will posting details on a new topic here about ten days before the event.

@Team_PR @Team_Electronics - RWK has 166 members. Lets prepare a handout to tell them about DMS. I propose a letter size sheet folded to give four pages. Team PR gets the first two. Team Electronics gets page three. The back page will list electronics classes. (I’ve been promising Jimmy Tanner something like this forever.)

[EDIT] Actually 214 members - around 80 attend the monthly meetings.

The back page will list electronics classes.

Be sure to include a link to the calendar so the page does not go entirely stale.

Edit: Also point out how to filter by categories…

You should take Walter’s demo direct conversion receiver. The Raduino VFO on it is arduino based. It’s also on my Bitx40v3 and uBITX.

[bpamplin]

Excellent idea! Walter was a highly respected member of RWK. Who should I see about using it?

[Bill]

Start with @artg_dms

[bpamplin]

@artg_dms - Do you have the receiver? It would be appreciated by this group.

[Adam_Overman]

It’s on the AR desk in the back of the Elab.

Here’s a thread w/some background.

We are MAKERS, so we should build our own radios!

To get more people started with building their own radios I am going to be offering a series of classes. In each class you will construct (from scratch, no kits) a radio for the 80M amateur band. By the end, if your diligent, you should have the skills to build a radio for any of the HF bands and any mode, We will start with building a morse code transmitter, which is a repeat of a few classes that @zmetzing and I taught last fall. I plan on talking a little about the process on this thread …

@artg_dms @Adam_Overman - That’s fantastic! I’m not sure how portable it is. I would like to pick up a couple of key components around March 1 and return them after the April 11 RWK meeting.

Art - Is that ok? I’m fine to go with just the picture and story if you would rather.

I would like to also have a slide in memory of Walter that mentions his DMS activity and many classes. Seems like there was something on the forum or wiki but I don’t remember where.

[artg_dms]

Take the board.
Don’t take it apart.
I think Adam has used it and found it in working order.

[bpamplin]

Thanks very much!

[Adam_Overman]

Yup, Ben and I hooked the antenna up and fed the beefy rails 12v it fired right up. It worked great, but it could use one more stage, a broadcast band filter. The raduino software on it is interesting because it shows just how far the community has developed it. On my µBITX I use [KD8CEC's](http://www.hamskey.com/) fork of the software which gives me CAT control by plugging the USB on the Nano into a computer. I’m using a rPI for my digital shack in a box build.

Here are a couple picks of my Bitx40v3 that show it.

[artg_dms]

Here’s some links on Talk on some of Walter’s projects.
Don’t think anyone made slides, etc.

PCB Mill Rebuild Progress

Walter and I spent several hours Sun.afternoon doing quick build of the mill and its associated electronics. The purpose was to test and get familiar with the following: test control board sftwr & hrdwr (http://synthetos.myshopify.com/products/tinyg) test mechanics of the mill and stepper motors test generating g-code files from gerber files (http://flatcam.org/) use generated g-code file to rough cut a simple board. We didn’t have an end mill, so we used a broken drill bit. Not pretty, but…

The video that made me appreciate machining

I keep waiting for that guy to post a video making the brass from copper and zinc ingots. Amazing.

DIY Induction Heater

Walter brought this in last Sat. Interesting possibilities… [diy_indctn_htr_01] Rebar starting to glow red. [diy_indctn_htr_glow_02] Pulls a few amps [diy_indctn_htr_amps_03]

Thank you artg_dms! And I second benhubel statement.

What a great tribute to a Silent Key (deceased Ham Radio Operator).

@Coul @Team_PR

I need to prepare handouts for the event described in the top posting above. I would like to prepare handouts on a folded piece of 8.5*11 paper. If you can supply files for the first two half pages I’ll add the info about Electronics committee and our classes on the last two. Please forward any files that would be appropriate to me.

Thanks, Brady

[Coul]

I didn’t see the OP back in Jan.

Would you rather a tri-fold which would give 6 pages?

I’ll see if we can get someone to dedicate some time over the weekend to put something together for you.

[bpamplin]

No problem.

If you want to take it on and do six pages that would be awesome. I can supply two pages. One page will be mainly a list of the seven Arduino classes that @NickWebb and I offer. The other page will be mainly the ~6 other electronics classes that others have offered recently and will be repeating. I can send you the info tomorrow,

If you don’t have anyone available, just send me general DMS content for two pages. Either way is fine.

Thanks to everyone who responded with help and encouragement. The meeting is Monday March 11 at 6:30PM and everyone is invited. Location is St. Barnabas Presbyterian Church, 1220 W. Beltline Road, Richardson, Texas 75080. SBPC is due east of Richardson High School on Belt Line Road.

With permission of @artg_dms, I will be picking up Walter Anderson’s Direct Conversion Receiver display to show. I will return it a few days after the meeting.

I’m not entirely sure if I can use the car early enough to get there by 630, but if I can would you like me to bring my bitx40v3 and µBITX that use the same raduino VFO with two different updated firmwares?

[bpamplin]

Adam - I have slides on about 14 projects by local hams and several will be bringing their projects including a uBITX but more is always welcome and your case certainly is unique. There is bound to be a story behind it. I’ll add your pictures to the presentation. I see your call is W9ECO.

I will only have about 1.5 minutes for each project. Give me a few sentences about why you like the BITX family of products. Also, how do you pronounce uBITX? Is it you-bitx or micro-bitx?
