I started experimenting with setting up my DM13As like this. Obviously the wiring would not be soldered so it's technically a no-no. photos.app.goo.gl/x7E4hgifrEYqKP418

This is Phil. Even though I'm an engineer, your videos are still wonderful. The latest are well produced and well sequenced. I love the format. The way your videos are done gives me a better way to produce any video I might do. It would be nice if you can show how you're progressing with your cockpit(s).

Hello Phil, wow all this time we've been in contact and I never knew you were an engineer. Thank you for the nice comments. As far as my cockpit, I really haven't done much with it in the last few years. Pretty much what I showed in my "Evolution of my home cockpit" video is what I have now. kzbin.info/www/bejne/iXeYq32Ld9KJja8si=SY3Eww2tOE7PQa_W&t=656 I have been thinking of starting an overhead panel and/or stating to use SimVim Panels but I just wish I had more space to build.

@@Qosmokid Well, building your own simvim panels takes time but if you use a dremel tool and other tools, you can make your own panels. This way, you can make them the size you want to fit. The comm panels you have are rather large and if you saw my latest video, you'd notice how it all fits together (of course, I use 3D printing - Cutting out panels takes time and I don't have the patience.) I was thinking of getting a CNC machine (about 200 to 300 dollars now) to cut out my own panels which would look better than the ones I printed and are more precise than 3D prints (you don't know how many tries I went through to adjust the various cutouts for each panel.) Also, although Vlad doesn't recommend anything but direct soldering, the best solution I found are the JST connectors that you find in various devices. You can disconnect and reconnect them many times without failure. I bought bags of 100 of different pins (2, 3, 4, 5, 6, 7, 8, 9 pins types both female and male) for about $5.00 per bag of 100. The male pins are directly soldered to the pc board and the females use connectors that you can either crimp with the right tool or, as someone on youtube said - solder the wire directly to the connectors. As for space for the sim, I have the same problem. I live in an appartment built in 1947 for the returning soldiers from WW2 so the appartments are small. I could take over my wife's work room but then, there would be hell to pay. As for designing boards for various parts like 7 seg displays, switches etc, I already did this for encoders, small push buttons with LED displays and even a board for a dual-axis stepper motor (which I might use to design an working altimeter some day) I enjoy designing pc boards and 3D printed parts so if anyone has a need for something, let me know. As far as taking time off, I did take a year off in order to figure a few things out so it's a normal thing. Currently, I am thinking of getting a curved 42" screen for my main display so that the side windows (screens) are closer to it than they are now. When I get my taxes back next year. The other thing I need to do is build the cockpit itself instead of using an old TV stand but, building takes time and I don't have the patience. Maybe one day before I pass on into the great beyond although at 70 years old, I have less time than I did 20 years ago. I wish I had all this technology then.

@@philnelson2364 Wow a lot of nice ideas here. I still have the PCBs you sent me a while ago but I haven't made use of the JST connectors. Now that I'm working on the 7-segment display videos I got inspired to do a more realistic MCP panel than what I currently have. I actually got sidetracked by that so I need to complete the videos on the TM1637 & MAX7219. You'll see my mediocre cutting skills when I post the video on my MCP panel. I had no idea CNC machines were down to a couple of hundred dollars. Last time I checked (many many years ago) I could've sworn they were in the thousands of dollars. Maybe I should look into getting one myself. I've also been looking at a 3D printer too but I probably won't buy either one of those until I live somewhere else :(

Great Video about wiring! An extra power for LEDs mentioned in video( like the adapter shown when video start), but still have no idea how it connect, could you show the power layout?

Just a comment about something that had me baffled for weeks about DM13As til I figured it out. The wiring illustration on the SimVim website isn't entirely clear with regards to how the pins are identified. The 24 pins on the IC chip itself are pretty straightforward - BUT there's a second set of numbers that apply to the LEDs. Yes, they're shown on the illustration but it's not exactly explained that the fifth pin down isn't really pin 5, it's LED pin 0. My LED was connected to the fifth pin so I naturally assigned it to Pin 5 - but of course it never worked. I reassigned it to pin 0 and bingo! I may be the only dummy who got tripped up on this but if your LEDs don't work, this could be why.

@larryspotts3266 Hmm actually the diagram does show LED 0, LED 7 on the left and LED 8, LED15 on the right, but you are right there is no explanation or correlation between actual IC pin numbers and LED positions. I Think I tried to explain that on the video. Glad you figured it out though. Hopefully this will help others, thanks for the comment.

Another very informative video from you Jose (I hope I spelt your first name right). I searched the Internet for a board with the DM13A on it, but couldn’t find any. Does one exist?

@Qosmokid 5 ай бұрын

@tzampini Hey, thank you. Yup, you got the name right 😁. I haven't found one either, so most likely they don't exist or else Google would find it. I'm experimenting with a new way of soldering some boards and molex headers. So far I like it.

@@Qosmokid I design my own pc boards and have created a "Main Board" which has the arduino mega, the 4067 multiplexer for the displays along with connectors and the dm13a socket, resistors and power connector to plug in a 5v power supply to power up all the LEDs, LCDs and displays. I am using it for my cessna c172 sim (which I use to stay up to date for when I can't fly for real.) I have the gerber files needed if you want to send it to a fabrication company like the one I use in Hong Kong which charges about $5.00 for 5 boards. If anyone wants to have a board for a DM13A specifically, let me know and I'll design one and create the gerber files (this is what they need to build a pc board.) If anyone else needs a board for some chip or other item, let me know.
