How to Mod a Kids Ride on Motorcycle: Adding Rubber Tires With Speed Control
I obtained a kids ride on toy motorcycle for free for my kid. It was well used and came without a battery. After placing a 12v in it, I discovered that it ended up too fast and jerky for my kid to ride it enjoyably. So this is a video of how to modify a kids ride on bike with rubber tires and a speed control to have a smoother ride.
The rubber wheels were purchased from Harbor Freight. The speed controller is a DC motor PWM module from online. There was some electronics patchwork that I made to interface the existing motorcycle's pedal to the speed controller to turn it into a throttle.

Using a paper clip is the cheapest, quickest, and possibly the eas...
Making the Open Theremin From Scratch
Просмотров 12 тыс.3 года назад
A while back my nieces asked me for a theremin. It was the first I heard of such device. A theremin is an electronic musical instrument that is played without touching it. It makes retro space age like noises and tones. I decided to get them one for their birthday. Eyeing the "open theremin" as a suitable candidate I set out to buy one. At the time, they were all out of stock so I figured I cou...
My DIY Boring Company "Not A Flamethrower" Nerf Knockoff, how to make step by step
Просмотров 6 тыс.4 года назад
If you havent heard, Elon Musk sold "flamethrowers" to promote his Boring Company. I wanted one but didn't want to shell out 500 bucks. Especially when his "flamethrower" is essentially a torch more so than an actual flamethrower. Therefore in making my own I made my design as such to be more of a torch. This is basically an extreme Nerf gun mod. Thank you to my friend for your generosity in do...

Brilliant ❤❤❤
Thanks!
University lab! But there seems to be a white layer on the surface of the water in the bottom pail, so that could stop the powder ahead of the 2nd stage.
Okay! That water's caught something-good!
Hello bro you're true Hero for us Thankyou for the tutorial 👍👍👍👍
Hooray! Great idea.
Bagaimana cara membuatnya
What site did you download the parts list and schematics
Download here github.com/GaudiLabs/OpenTheremin_V3
Particle and well tested! Lol
Brilliant
That was brilliant. Can this be done at a lower voltage though? Trying to think up a way of doing this on a smaller scale - likely with a fan passing air thru
It can be done using a static electricity generator that produces a much lower current which is much less likely to kill someone than using a microwave oven transformer but that is still high voltage. The high voltage is necessary to establish a strong enough electric field to attract particals as well as corona/ionization to charge the particles. The only low voltage means would involve mechanical filtration and heat based filtration techniques.
Awesome I was going to build one to scrub the nitric acid from the lab extraction hood.is it In the shops yet👍
I'm glad you were having the same problem as me in the beginning. This video and comment thread is like a recovery help group.
Thank you this was fast and effective
Great job! Thinking I’d like to make one with my kids:)
Awesome
Excellent ❤
Thank you ❤
omg haha best vid in awhile!
Oh my gosh...I just found this video because I have this problem and I haven't laughed this hard in a long time!! Thank you for the hack.. and laugh!!😂
so simple yet genius!
Perfect! Thanks for the simple explanation and the funny, real-world testing demonstration! 🤣
Can you share the files that you used for the PCBs? I have some students who would love to build this but I can't also walk them through the PCB design process.
github.com/GaudiLabs/OpenTheremin_V3 Here is what I used. There is a newer version out apparently
Love this, can’t wait to see what you build next.
Fantastic! I love it too that you have involved your daughter when doing the modifications. Keep it up bro 👍🏾
THANKYOU
THANK YOU!!!
GREAT video: PLEASE HELP ! ! wouldn't it operate the same if you just had a U shaped trap at the bottom of the main water exit? That would eliminate the need for a "T" ? ? Someone please help me understand why a simple U trap wouldn't do the same thing.... Thank you all in advance for the hundreds of replies I'm sure I will get to this question.😀
Great question. So a simple U shape will not work for the following reason: the water that is in the chamber would not be displaced past the opening tip of the "u". Imagine a full chamber. Water level drops as air displaces chamber but the water level drops past the entry of the "U", the only water that is displaces is the small amount within the U bend.
Wont there be any ozone production as well? Or are the activated carbon pods a solution for that problem
Yes unfortunately with esp there is always some ozone produced. The activated carbon would absorb some. There could be one pod made from a specific absorbent for ozone which are similarly used in cpap machine cleaners. Other option which I was exploring was to use an electro spray technique which I couldn't get to work as effectively but that could have just been my inability to produce a good setup with optimal parameters.
Awesome video yet some parts funny.
For ESP's, what's the key factor for the amount of ozone produced?
its the corona that will produce the ozone. From there it is the voltage level how the terminals are designed to produce the amount of corona and the amount of oxygen present to be converted to ozone. I believe the polarity of the voltage has an affect with positive voltage producing less than negative.
@@LockeLaboratory I'm intrigued by this type of air filter and intend to build one to remove solder fumes, but the ozone worries me more than the fumes. When you have worked with this, have you ever felt a certain smell around the apparatus? (It's a very distinct smell)
@@LockeLaboratory Also, can the corona discharge be tuned in order to produce less ozone without making the filter less effective? And kudos for being active 8 years after you published the video 👌
@@minime9400 thanks! Yes ozone is a real concern which may negate the practicality of this device for home use. There are some moves to minimize effect of ozone but it will never be zero since corona is also required to ionize incoming gas. In general what increases ESP's filtering power can increase ozone generation rate unless you do something expensive or exotic such as using an oxygenless environment or perhaps converting to electrospray to turn the ESP to a wetscrubber. There are optimal parameters for ESPs and I'm sure there are research papers written on it. In general sharp protrusions increase corona production. Typical design is a wire within a cylindrical tube or wire sandwiched between plates. On the wires are the series of barb protrusions to concentrate the electric field where corona is produced. Yes stopped making new videos since not much time anymore. Hope to find the time again to make more videos while juggling a busy life.
Brilliant - so simple too! I did the exact same rage quit with my hooks this morning... Now hunting for paper clips...
very cool
....WOW!!!!!! I WANT TO KNOW IF A "THEREMIN" WILL RESPOND TO ANY "METALLIC" OBJECTS, WITHIN PROXIMITY TO IT'S ANTENNA?!!!... COULD THIS BE USED TO "SWEEP" OVER TALL GRASS, TO FIND METAL OBJECTS?!!...
I dont think a theramin would do a great job of this? I think the antenna responds to grounded objects such as a person. A metal detector would be a better tool for finding metal.
Good idea
you might be able to improve the working of this device by also adding in some soap. doing this will reduce the water surface tension, as well as making it more easy for dry and/or hydrophobic particles to get into the water and stay into it.
Love it. You had me cracking up 😂
Thanks for this. I was looking for a way to deal with a huge amount of wildfire smoke that didn't require constant cleaning of metal plates.
I like that they are not permanent. I have even triedt to use adhesive caulk but it fails because of the changes in the temperature in my garage and the coating on the board. I like your real world testing method. 👍
Good humor man
Very clever!
Hi Jimmy, how do you ground the theremin? I didn't understand how do link the test lead to the earth port of the main outlet. what do I need to buy to that? Thanks.
There is a grounding pad on the bottom of the theremin. I just used a clip on test lead to clip onto this ground pad and with the banana jack end of the test lead into ground port of an outlet.
@@LockeLaboratory thank you Jimmy
Want to remove all the fine particles without either a filter or a scrubber? Just exhaust to the outside of the building...
Very clever, and humane of you!
No, this is not a good solution. The clip is ugly, flimsy, and occupies the space where the tool should hang. It looks dreadful and messy, not neat. A creative idea, but not a solution. I am sick of the price gouging on flimsy junk that is sold as a retainer clip. You have two solutions: Use hot glue gun to keep retainers glued in place, or build a plywood tool hanging board with custom storage for all tools. No more pegboard! The advantage is, you can build in sections so it is modular and easy to move along with you, or as a folding cabinet - no dust, layers of walls inside for compact storage.
You silly!
Hi Jimmy, how difficult is it to solder the parts following the BOM? Found a seller on Aliexpress that sells the PCB with components - just need to solder the parts onto the board and install with a arduino. wonder will this be doable for someone with no soldering experience. thx
I would always encourage trying and taking a dive to learn new skills. It can be fun, kind of like building a model. Its kind of like learning how to ski, first time is often lots of failure but by the end of first session you may have already gotten the hang of it. If you have a steady hand and the right equipment, it isn't too bad. The trickiest parts for this kit may be the header connectors that adapt to the arduino as well as the IC chips. I'd recommend also getting a practice soldering kit to try first so your first try isn't spent on the theramin kit you found. You will need tweezers, flux, solder, solder braid, and a temperature controlled soldering iron. Best of luck.
Thank you so much. I'm about to install my peg boards and hooks into my new art studio and thought about the hooks falling out. Found this video and it's gonna save me from frustration not to mention using all these paper clips 😊 Also thanks for showing a realistic rough handling 🤣🤣
Thanks, mine were falling off
I use a staple gun to hold the peg in place. Want to move it? Just use the peg to pull it out.
