  • kayakdiver commented on bjarni1995's instructable Using FM RC Controllers With Arduino3 months ago
    Using FM RC Controllers With Arduino

    Modern TV Remotes transmit a Serial Bit Stream that encodes the various commands much like a Serial Communications data stream, with repeating "packets" of Start Bits, Toggle Bits, and Data Bits, so long as a button is held. The signal is NOT a constant PWM Duty Cycle such as is the case with an RC transmitter set to a specific setting of thrust/deflection/rotation, etc. So, the answer to your question is "no".

  • FIRST DIY ELECTRIC SKATEBOARD BUILD - 30mph

    Great pics and nice write up - thanks!Looks like what is supposed to be your Controller Link is the same as your "Paris truck motor mounts" Link, parts which, BTW, are currently unavailable...- General electric skateboard controllerhttps://www.amazon.com/gp/product/B07FD1K9Z1/ref=p...

    It looks like the motor mount plates are high enough that they would have limited the lean/turn ability of the board if they has been positioned forward and somewhat under the wider part of the board.

  • Dual-Motor SIP&PUFF Controlled Kayak System

    I am currently investigating a redesign of the Motor Controller using a Cytron Technologies (Cytron.com) SmartDriveDuo-30 Dual-30-Amp (Continuous, 80A peak) Motor Driver. This board is under $70 and looks like it has all the features I would need to match the functionality of the RD-160.

  • EASY 3-PERSON CAMPER WITH OUTDOOR KITCHEN & SHOWER, BATHROOM, AND SUNDECK

    Thanks for that! I am a few years away from retirement and I have given just that some thought for a little extra income. I think if I started on three at a time I could not only greatly improve and simplify my design but make them in an average of a little over a month each in spare time. My build cost me about $1800, not including the trailer. A new build would be about $2200 and weigh well under 2000 lbs. making if attractive to owners of smaller tow vehicles. I'd probably have to sell them for a little over $3000 to make it worth my retirement time (but not at my current salary).There are a couple thoughts for anyone else considering this build.1.

I'd probably have to sell them for a little over $3000 to make it worth my retirement time (but not at my current salary).There are a couple thoughts for anyone else considering this build.1. The Harbor Freight trailer is a little on the narrow side. Consider widening the axle and adding a leaf to each side for more stability. Also consider adding a stiffener beam from the tongue straight back to the second cross-support of the trailer frame.2. In California, if you keep the total length under 16 feet (like my design), you will be eligible for a Permanent Trailer Tag. Registration and license fees are one and done. You could have fold out sections if you need more space.3. My favorite feature is the fully walkable roof deck, Make sure it is structurally sound and water-tight, and has a guard rail!4. Don't skimp on the insulation. I used aluminized (on one side) Styrofoam panels in every wall and ceiling cavity with the aluminum facing outward as I am more concerned with heat than cold inside. With the sun making darker painted exterior areas almost too hot to touch, I can barely feel any heat at all on the inside.5. The outside Porta-Potty room is a great convenience, especially for the ladies on a cold night. If I did more cold weather camping, I might find a way to pass a little warm air from the main cabin into that room.6. I might add a better, and more convenient shower area, especially if I start doing more cold-weather camping. At the very least, I'd be able to stretch the privacy screen taught all the way around at the top AND bottom. A heated water source with 12V pump would also be a great addition, as would be a way to warm up the shower area a bit. None of this is needed in warm weather, where I just heat several galloons of water per shower needed on the hood of my car.

    The variable GotCmd could have been named GotVeryLongSipOrPuff. It only gets set above zero when a VERY LONG Sip or Puff is detected. Otherwise, the Counter is checked to see if a (medium) Long or Short command (Sip or Puff) was detected.

    Kalaha Board Game

    Nice job! My daughters taught me a slightly different version of the game and called it Mancala. The rule (they taught) that differs from yours is that when your last bead in a turn ends up in Any Occupied Ambon (but not Home), you pick up all the beads and continue dropping one-at-a-time into successive Ambon pockets including Your Home pocket. Your turn ends when your last bead goes into an Empty Ambon or Your Home pocket. I also think I remember that the opponent didn't get to move their stones into Their Home pocket when one side Ambons were empty, ending the game.I have Not researched to see if this is the most popular rule, but it works, and adds speed, strategy, and fun to the game.

    How to Make a Newton's Gravity Puzzle

    Half right, in a way... Newton is keeping it down, and Bernoulli is lifting it up. Those two have been at odds (mostly) since the days of Icarus! Cool little trick toy!

    I would suspect that you work just about anywhere outside of North America, the UK, or possibly Japan. I think it is generally agreed that a purely decimal based measurement system ultimately makes more sense and is (or would be) easier to work with than the seemingly arbitrary inches, feet, miles, etc. (as well as ounces & pounds Vs. grams) we use and are way more accustomed to. With that said, neither is more precise; just add a couple of decimal places to get to the precision you desire. Woodworkers alone, however, might argue this doesn't apply when working in 64ths, 32nds, 16ths, 8ths, etc. of an inch.

    What a nice Instructable... a great reminder how easy it is to let someone you know you are thinking of them! Texting can be fun too, if you don't over-use it...Why am I commenting now...?Imagine one of my favorite photos of my GF, a beautiful Persian gal with hair that often sticks out like she just stuck her finger in a light-socket... A few hours after I got to work this morning, I texted her along with that photo the following: "Remind me again why I love you so much... Oh, never mind... I see it now! My WC!!! (heart emoji)".Referring to her hair, always colorful & fun, and often mismatched (on purpose) outfits, she knows "WC" is short for "Wild Child".

    How to Write a Horror Story

    Yes, little miss ElkeMa, horribly good! And now..., I shall haunt you in my dreams for the rest of my miserable life, and then beyond that for eternity. But oh, will I really be sleeping? Or will it be the heavy doses of Ambien taking control of my inner consciousness, driving me out into the darkness of night to do the things I would never do in my waking hours? We shall see... We SHALL see! ;-} Happy Halloween!

    According to your text... Mission accomplished!On a more serious note... I have MUCH to learn as a writer and I was thrilled to see your Instructable with some great guidelines and ideas. While I am currently (slowly) working on a semi-fictional dramatic action novel, my previous experience is mostly in writing technical documents (mostly in aerospace engineering disciplines) and "how-to" manuscripts (in the pages of KayakDiving and DisabledAdventurers .coms).Thanks again!!!

    Spider From PVC Pipe

    NICE! Great idea for all the unused PVC I have in my stock! I am thinking about how this could be configured and decorated to look like a threatened tarantula: painted black and brown, faux fur added t legs and covering over abdomen, raised head, reaching fore-arms, etc. Also... perhaps replacing the L's with V's and adding an additional leg segment might be a nice (and more realistic) effect.

    Cool, fun project - you put a lot of GREAT work into this!I agree with the added motion... It appears the heart may be made of a flexible enough material that (perhaps) an embedded servo or an off-center motorized wheel could cause beating motion. Other than that... One could dissect old printers and get lots of gears out of them for this project.

    Yes, that could be a possibility, and if added inboard towards the axle, ground clearance would not be affected so much. With that said, this plan has more than enough storage for my needs. Not shown (due to time for the contest) is a 16 inch wide (sort of) counter top that runs from the forward bed (at top-of-mattress height) to the back interior wall. There is an equally large 9 inch deep drawer hung underneath it. And, I am considering adding another shelf above the starboard window, just because that inside storage space is so handy for books, extra candles, extra clothes, etc...

    I am considering adding a permanently affixed ladder that tips out at the bottom during use. The angle makes it MUCH easier to use, especially when carrying things (water for shower, lounge chairs, etc.) to the sun-deck.

  • EASY 3-PERSON CAMPER WITH OUTDOOR KITCHEN & SHOWER, BATHROOM, AND SUNDECK

    Thanks KJ! The dark blue matched my original tow vehicle, a 2WD 6-cyl GMC Safari van. I minimized that darker color as it gets very hot when being hit directly by the sun, although the heat didn't pass (much) thru the insulated walls.My new tow vehicle is a graphite colored 4WD 4-cyl turbo-diesel Chevy Colorado truck. The graphite color is pretty dark and has a hint of green in it. Don't know if I'll try painting to match that.I think the white stripe in the channel between the two blue colors was key to a "sharp" look. I also added a few tablespoons of blue to the gallon of grey paint I used on the upper half.I used a slightly lighter grey color on the roof deck because white, although cooler, was way too bright on the eyes.

    I think if he had (perhaps pinned and then) only clamped the pieces together for the carving and sanding process, he could have taken it back apart for the burning process, keeping in mind that he might have still ended up with some slightly uneven edges after putting it back together due to material loss or shrinkage in burning.Perhaps a better idea is to use a darker, and even reddish, wood for the red stripes and skip the burning altogether, although I think the burned wood looks very "cool".

Hooking them up to 4.5V backwards (for a while) probably won't hurt them, but they won't light up.I'm not surprised these cheap lights, of which I have many and love, don't have modulator circuits to make them more efficient and brighter without affecting life.
