This channel has three main topics surrounding some of my interests -- flying, motorcycles and electronics. Although I'm regularly engaging in all three activities, I tend to focus on making videos in one area at a time. So if you like my flying videos and only see new electronics videos, just be patient. Hope you enjoy my videos - I have enjoyed making them.
I live just outside Portland, Oregon in the USA.

Motion detection Using ESP-NOW
zhlédnutí 389Před rokem
I build a motion detection device using ESP-NOW in broadcast mode. I used two ESP32s although it would also work on ESP8266s. I go over how I set it up, programmed it and improved the final design. I got the idea from the following webpage: dronebotworkshop.com/esp-now/
Stand-alone Serial Monitor for Arduino Projects
zhlédnutí 2,2KPřed rokem
This is an ESP8266 based standalone serial monitor for Arduino based projects. It uses an ESP8266 and TFT display to read serial data from any device that outputs serial data on any Tx pin. This project can be built using any microcontroller that will work with some type of display.

I came to the same conclusion (see 5:30 ...) when I built a gadget for a friend. What do I do with all the 555 in the drawer now?
Made my own board with an attiny1616, I am so happy that we live in an age where you can just easily design pcs and buy them.
Cool.... and tiny.
I would never ride such routes as you do, with either no lanes or merely painted bike lanes. Way too scary imo. But hills, un-plowed snow, rain, etc... Will do every day of the year pretty much. The exercise is just so worth it. Wakes you up real nice. Much easier to stay in shape. I hope you get more safer routes as well, it's nice to be able to relax while riding without an increased risk of getting rear-ended or sideswiped. Also that would really help with more people realizing cycling is a decent commute option.

Are you still flying? I just got my PPL at Twin Oaks last summer/fall. I've only flown the C150's so far but might work to get checked out on the C172 and/or Vans RV12 this summer. After completing the checkride last year I've only flown 4 times so I'm feeling like a rusty pilot as well!
Yes, I'm still flying but I seem to spend a lot of time as a rusty pilot. I only have two flights in the past 90 days due to tax season and a family vacation. I started on my IFR a few years ago to try and fly more but life still gets in the way of my flying.
Yeah, you had a really terrible headlight on that bike. I hope four years later you have got a much better one?
I've started commuting by bike out of necessity the last 2 months since we are down to one car. I think I'll keep riding even after we get 2 cars again, even a "bad" ride is a good ride, makes you feel alive.
What about Forest M. Mims III books They are Great IMHO!
My first book on electronics was one of his books I purchased from Radio Shack back in the late 1970s. After making that video, I found those old Radio Shack books online. They are a great way to learn.
@@markgunnison I bought books at Radio Shack when they were closing and have since bought CDs with his books on them also Thriftbooks has some books.
Aviate Navigate then film.🤣🤣 I am having a 355 and 2 275's installed in my M20J. I see a com 1 on the 355. Is there a nav 1 as well? Thanks!
No Nav just Com. I have a standalone VOR/ILS. When it dies, I plan on adding a com 2 that has a nav/com. Hopefully not for a long time though.
I live right near there. Can't wait to start my pilot training. Thanks for the inspiration!
Twin Oaks is a great place to get your training. I really enjoy flying out of there.
This bike isn't built for single track you clown, everyone who buys this type of bike knows this, it's much too heavy just like all the adventure bikes above 1000, just like the KTM, BUCATI, etc.
Do you have any book recommendations for a shop Projects
Looks amazing, thanks for sharing. My pieces are being frabricated for my Cessna 172D as I type this. I opted for all the bits for the interior, $5,330 all-in from Airtex. I'm pretty excited about the project, and appreciate your insight.
I'm sure you will love it. I've had mine for a few years and am still really happy. It is also nice knowing if someone damages a seat in the future I can easily update just the seats without spending too much.

I recently bought a 2017 GSA used ilo an RT. I was looking for an RT but this bike came along in pristine condition. I bought it to ride on road pretty much. I think it's an awesome road bike that looks cooler than an RT but I have other smaller bikes to go off road. Great video.
Thank you. Yes, my bike spends all its time on the road now. I had run riding it offroad for the first few years but at this point it is just a road bike I can take off from time to time. I still love it after seven years of use.
Very nice! Would be great if you could provide part numbers and sources for the parts as well as a wiring diagram. Thanks!
Fabulous Mark! Yes, you have got it completely right! I thought I had an old plane (1963 Piper Cherokee). Yours looks great! I loved the flying I did in the US and the fuel was so much cheaper and flying on floats too! czcams.com/video/ZvlxJ1oLCb4/video.html
I looked you up. We lived in Florence, Oregon before moving to Florida. John Darke
Back in the 1980s my grandparents lived in Yachats, Oregon. I have a lot of memories from that part of the coast. Don't get down there much now though. I imagine it is easier to find good flying days in Florida 🙂
Can you share the file you uploaded to have the pcb made and which ESP based controller are you using. I found the TFT kit
I've done that same landing. When I was 16, I took some lessons there back in the mid-90s. I don't recall my flight instructor's name, but I recall he had one hand and a dog name Rocks as he loved rocks. Great dog. I'm in Portland these days. Did you start at HIO?
I was flying from Twin Oaks (7S3). I miss going up there. Sadly, my uncle passed away a few years ago so I don't fly up there anymore. It is a good memory re-watching that video though.
"Bebop to the Boolean Boogie" - best book on semiconductors and circuits
Hi Can you please share the wire connection from display to esp82 directly? didn't find such an pcb anywhere
You can see the code at my GitHub page. They are at the top of the code commented out where I should how I setup the User_Setup.h file in the TFT_eSPI library: github.com/markeg1964/Serial_Monitor
Excellent work sir. Is it possible to get sketch? Thanks
I saved a copy of the code at the following URL: github.com/markeg1964/Serial_Monitor
@@markgunnison Thanks sir really appreciate it. One more question what is the size of TFT 2.2 or 2.4 inches? also when I am compiling it gives this error exit status 1 'class TFT_eSPI' has no member named 'setTouch'
@@AAdnaanmtl I'm using the 2.4" screen. It has been a while since I worked with the code but as I recall the line "#define TOUCH_CS 5" is all you need to include the touch functions. That line is somewhere in the User_Setup.h file. As I recall, it is not close to the other lines that get edited in that file.
@@markgunnison thanks sir for your precious time and kind response. When I went through all User_Setup.h I just found this line //#define TOUCH_CS PIN_D2 // Chip select pin (T_CS) of touch screen. Are you talking about this ? If this is the line it means I need to uncomment if I am not wrong.
@@AAdnaanmtl Yes, in my example I'm using pin 5 as the touch chip select GPIO pin.
Could you find out why your prototype crashed every day?
Yes, it sometimes has a stack overrun. Occasionally an airport METAR will omit most of the fields. This caused my code to look for something that was not there causing an overrun.
That’s just beautiful, thank you!
Nice videos! I took a discovery flight recently at 7S3 and it was great. Hoping to start my flight training for a PPL next spring.
Good luck getting your license. I learned to fly at Twin Oaks around 18 years ago and really enjoyed it. Don't feel bad about taking your time. It will take a bit longer but you will have the opportunity to fly with an instructor in various types of weather.
Te attiny85 is a lovely processor, and I have used it a lot. However.....it is too expensive. One can get an arduino pro mini for just a little bit more
I love to use them to make led's blink with a pb to cycle thru different timing cycles.
Great video, nice panel setup. Looking forward to doing the same on my panel, safe flying.
I'm sure you will enjoy it. I have been flying with the upgraded panel for a year now and really like it. Well worth the cost.
CZcams is not cheap. Ordered this one today: Basic Electronics Theory With Projects and Experiments 4th edition.
Thanks for sharing. Great review. Very encouraging review. In Aug. 2023, i acquired my first ever BMW GS1200. Yes it's heavy (so is a Gold Wing or a Harley Davidson Street Glide). I am small person at 150lbs. and at first sight it was an intimidating machine which gave me an impression i was about to hop on a Battle Tank! But after hours and hours riding the bike the weight was something i just had to live with and learned not to focus on too much. To me, it's not just a great bike but a wonderful bike.
When I was in my twenties, I used to bike commute and I loved it. Wish I'd kept at it, but in one of our many moves, my bike pedals were lost and our last home before our current one, it was too far and too dangerous to bike commute. Haven't done any cycling for 20 years, until now. I'm also in my 50s and recently started bike commuting again, unless, like before, the weather is bad. Only where I currently live, rain = hail, so I don't want bruises all over my body. Otherwise, I would do it then too. It's great when I can, because it's so peaceful and I get a great workout before and after work. Hoping to keep at it.
Good luck. That video was posted three years ago. I'm currently not as committed to commuting on the bicycle as I was when I made the video but I still try and commute on the bicycle as often as I can.
I have the same issue of a short ramp. Where did you buy that ramp
It is a Fly folding ramp. I got it around ten years ago at my local Honda shop. It is a really nice ramp but it was around $100.
@@markgunnison thank you very much
Grande cache alberta canada, beaver dam road off trail. This video is absolutely nothing compared to the root trail up here offers.
Yes, my riding buddies still make fun of me for this video. The roots in this video don't really count as roots. Luckily I have improved over the years :-)
Great video.
Excelente
I know this is an old video but I can totally relate. As a 43 year old I've been riding on road for decades but tried riding dirt bikes off road late last year. I've probably logged 6 hours total. And this is absolutely how I felt the first time out. I've noticed a few things built confidence quickly. 1. riding multiple days in a row or weekends in a row you just get the feel of the bike so much faster. 2. standing as much as possible especially on anything remotely technical... even up hill I just stand and crouch with my butt back to weight the rear tire. 3. setting up the bike well for my tall-middle-age-self. I used lower pegs and steg pegz which helped so much for climbing hills for me. I also added a throttle tamer to my ktm because I was struggling with how much engine braking there was. All of those mods gave me much more confidence and made me feel more connected to the bike (bar placement and suspension matter too). Lastly ride with someone who will push you a little from time to time but also understands your limitations. Great video!
Yes, that is one of my older dirtbike videos. I agree totally with everything in your comet. I didn't try lower pegs but I did try everything else. Now I'm usually the best rider in the group of guys I ride with. I wish I had riders much better than me to ride with. I also found Steg Pegz really helped. Especially in getting me to stand when I would often want to sit. After a few years of using them I did take them off as once I learned to grab the bike I felt I was better without them. They were well worth having though as I learned a lot from using them. Good luck.
What is the lumen for your front headlights?
I have no idea. I no longer have that light. I always use fairly cheap lights and have been happy. My current light is a 3000LM light and I'm happy with it. I struggle to see when it is totally dark and raining but it works OK.
Well, I'll be! Mark, while surprised you are learning such stuff, I'm pleased to see that you have dived in! How are you these days?
Tomorrow is the last day or tax season. I will be much better Wednesday :-) I Actually I'm doing pretty good. I got married six years ago and am enjoying life. Not doing as much CZcams though.
@@markgunnison , ha ha. I always seem to catch you around tax season!
5 time constants, Sir. There is a better formula. Although it is a wee bit more involved. I love the fact the hobby has so much to learn. Plenty of fun in the shallow end we can go as deep as we like!
I had 12 hours in a Cessna 172 markii waaaay back in 1985. Never continued because I had insufficient funds most months.
Yes, my problem has been finding time. I've decided to make flying more of a priority and started working on my IFR rating.
Came for the electronics videos.. stayed for the flying. Amazing.
I prefer PlatformIO, too. The chip is interesting (we are truly living in the future) . I see it as more of a device for wrangling sensors or other input and to pass data to different parts of a larger system.
Very impressive. That's actually quite useful and I should build a serial display, too. There are many times one would want to check in the health of a project without having to drag a computer with you. Just be careful of levels ... The dreaded 3.3v / 5v issues that have bitten me in the past 😀
Yes, it was pretty useful when I needed it. It has been sitting on the shelf since then though 🙂
What a wonderful place to while away some hours. As a fellow enthusiast I recognize the joy such a space provides.
Have you, by chance, read Electronic Principles by Albert Malvino? I've been told it's a game changer. Apparently, his explanation of theory is incredible.
I will have to check it out. I'm always looking for something interesting to read.
@@markgunnison Sounds good! Enjoy. Thanks for your book recommendations..
@@boeing757pilot I'm also a pilot. I recently started working on my IFR... again.
@Mark Gunnison Good for you! And good luck! That's how I came up.. Private to ATP... As for aviation books, have you read Stick and Rudder? Probably the best explanation of flight ever written and HIGHLY recommended. It's been in print for nearly 80 years! If you're interested in a great conceptual approach to aerodynamics, check out Illustrated Guide to Aerodynamics by Hubert "Skip" Smith. You can find both on the used market for cheap.. Good luck!
@@boeing757pilot Yes, I read Stick and Rudder years ago. I learned to fly in a tailwheel - an old Cessna 170A. I currently have a Mooney M20B. Flying is just a fun hobby for me like electronics.
I have really strange question for you. I own the exact same plane. The door latches at the top when you close it. The small vertical bar that the door latches too has become damaged on my plane. When you removed the headliner in your plane did you have access to that vertical bar? I cannot think of any other way to access it but I am hesitant to cut into my headline not know if it is worth it.
I know what you are talking about but I can't remember. I just looked through all the pictures I took during the teardown but unfortunately I didn't catch any of the latch. Off hand I can't remember how that part of the headliner is held on. However, I did just recently pull back part of my headliner on the pilot's side to install a new GPS antenna. It was not bad pulling it back and reinstalling it. I'm not sure about the passenger side though. I would start by pulling the trim piece near the windshield with the little screws as it is easy to remove and reinstall.
Nice electronics workbench! I have also built my electronics workbench to get me back to electronics and sharing my knowledge and experience on electronics.
I just subbed your channel. I had actually watched your workbench build. Looks like you used some pretty nice wood. I will look forward to more videos.
Thank you Mark. I recall that 63 percent figure from years ago but couldn't tell you much about it anymore. I just got a new piano keyboard from Beth for my birthday.... early. Lots to relearn. God bless you and Beth.
