Ham It Up

Hello Mr Fid,Very nice project! I've been a ham radio operator for years and mostly use morse code only to communicate around the world. I use only 1 watt of power and communicate over the entire world using Morse Code! I wrote an iPhone Morse Code app over 2 years ago as a teaching aid. It's inactive now because I haven't renewed my Apple Developer Contract. Maybe I'll renew it again. Keep on making these great creative projects!_ .... ._ _. _._ ...Gary

Great project!A friend and I were just talking, recently, about the split-flap boards used at airports and train terminals and how we loved the sound of them when they change their data! I just thought about building one of these just 2 days ago! I can't believe that I received notice, from Instructables of your project, today. Wow, what timing! Thank you for doing all the leg work. I'm thinking about expanding mine into more flaps and programming the arduino to display random known phrases and change the phrases within a short time span. Maybe every 10 or 15 minutes or less. I like your idea of connecting to the internet and retrieving real data. Can you tell me what the original boards used for their flaps? Are they made out of aluminum or thin steel? I know you used acrylic but I'm ...

Excellent idea and build!

Can your printer run ABS filament and if so would it be necessary to build an enclosure to maintain a constant temperature?Thanks,Gary

John, I'm fairly new to the world of 3d printing but I've used them enough to realize that you did an excellent job of building your printer! Not only that, I can't believe all the work you put into posting all the details.You've practically provided a complete manual on your build. Very excellent work!I belong to the Dallas Makerspace and have access to lots of tools and equipment but I don't know if I have the confidence to build one of your printers, yet.I have a question for you. Can your printer run ABS filament and if so would it be necessary to build an enclosure to maintain a constant temperature?Thanks,Gary

WARNING! PLEASE DO NOT try this method!Wow! You like to live dangerously John! Glad that method worked for you and you're still with us in one piece. It's not one that I would endorse or encourage people to use. Any volatile liquids or gases trapped in an isolated space can easily explode and of course explosions can cause bodily injury or injuries.

Great minds think alike! Wow! It's interesting how us humans think alike. Your instructable is a perfect example!Thanks for your comment.

Great idea! It's interesting to hear how other people would solve the same problem.

Thanks for your positive comment!In my rush to get this Instructable written up in order to enter it in the "MacGyver" contest, I left out the clean up around the rim and removal of any rust. Thanks for reminding me of that step. That's something that should be looked at before inflating the tire.I hadn't seen or searched this method of inflating a small tubeless tire in the past. It's an original idea for me and became a solution when I had this problem with a wheelbarrow tubeless tire about 3 or 4 years ago. Unfortunately, there are so many people in the world that the odds of someone coming up with the same or similar idea is extremely high especially with today's world populations. That makes it difficult to come up with an "original" idea before someone else.An ...

Unfortunately, there are so many people in the world that the odds of someone coming up with the same or similar idea is extremely high especially with today's world populations. That makes it difficult to come up with an "original" idea before someone else.An example is a man by the name of Elisha Gray. He invented a "harmonic telegraph" that could transmit musical tones but not speech. This was at the same time Alexander Graham Bell invented his "harmonic telegraph" which could also transmit musical tones but in addition it could transmit "vocal sounds".That was a close call on who got the patent. Had Gray's invention been able to transmit "vocal sounds" then we all would have been talking on a Gray telephone instead of a Bell Telephone! It would have been Ma Gray instead of Ma Bell and the rest is history!

diaaamin, very creative! I like your re-use of parts from the old hair dryers. I like to re-use motors and parts from old appliances. I have a couple of old hair dryers. I need to use one of them to build a "tube man". Gary

Thanks for the positive comment! I'm still new at this so, I've been updating my instructable to make it easier to follow. I'm thinking about adding a video of how I built it in Tinkercad.

Excellent paint job! How did you get the clean lines between the two different colors?

Linn,Another great idea using concrete! I like playing around with LEDs. I'll make a couple of these. I thought about making a cavity just large enough, in the top, concrete block where I could install a push button on/off switch. Install a small piece of tubing (plastic) during the molding process for the wiring to run through. I would glue the switch in place. (polyurethane glue!)Gary

Hi darbinorvar,Thisis the first video, of yours, that I've viewed. Very, very good! I have fourmajor points to make about your project and presentation.First,I have to compliment you on your creativeness and "thinking outside thebox". Most of us, as adults, lose that skill but can renew it by buildingprojects like yours. Second,your project lends itself to experimenting, renewing our "thinking outsidethe box" skills along with learning about the physics of sound. One couldchange the shape, depth, and size of the concrete block and its enclosure, on atrial and error basis, to determine which parameters give the best or desiredsound.Third,your mechanical skills are excellent! I like your wooden mold idea and usingthe veggie oil to prevent the concrete from sticking to ...

I like your wooden mold idea and usingthe veggie oil to prevent the concrete from sticking to the wood. I also likeusing the blue tape to assemble and hold your final enclosure together whilethe glue dries. Miter joints can be very difficult to assemble but you'vesimplified it for this project. Fourth,your video and presentation, of your project, from your initial idea, drawings, and your failures, plus successes, that led to a final tangibleworking product was excellent! You've included the very details needed toachieve success in duplicating your passive speaker cube.Iwill be making and experimenting with different cubes.Thanks,Gary
