JonnyBGood's Other Hobby

Well this may seem out of place in the K'nex forum, but since I am a member of the group I think this still applies. For the last couple of months I've been pretty inactive as far as my K'nex building has been concerned but as you can probably see from the pictures my time was being completely consumed by my Nerf hobby. Let me also state this while I'm at it.... No this does not mean I've stopped K'nex building, I've just been sidetracked for awhile. My reasoning for moving to Nerf is mainly because of a resolve I made at New Years to start tinkering with electronics, and of course I wanted to keep shooting projectiles so Nerf was perfect. It also allowed me to participate in more wars, again I love K'nex and I look forward to our once a year K'nex war, but one isn't quite enough for me.  Nerf also gave me one other edge that I wasn't getting with K'nex, and that was a marketable product. Kids are willing to pay on average (based on me stalking ebay for a month) 40-80$ depending on gun and paint job quality. So I have a possible source of income custom painting Nerf guns.  When should I expect another K'nex ible'? Well I have one last Nerf build I really want to do ( rapidstrike uzi ) and after that I will refocus of getting some war guns together for the K'nex war this year.    So in summary, that has been what I've been up too. If you like any of my work and would like to make an offer I will gladly consider anything reasonable, so send me a PM. I plan on eventually selling "Vanguard" themed white Strongarm's because I can paint those relatively quickly. The Rayven Roughcut integration ( Mine is called the Universal Remote) is my piece de resistance right now and I'm insanely happy with how it's going. If you know a friend that may be interested in my work, I'd appreciate any referral. Also note that I'm not doing any commissions.... yet. I'm kind of addicted to the art of making a well painted and functioning Nerf gun right now.  Thanks for reading, more K'nex projects coming soon!     JonnyBGood

Legalizing hobby distilling

Would you take a minute to contact your US Representatives about HR-2903 and US senators about S-1562?  It's a pair of bills that would enable small-time and hobby folk to distill small amounts of alcohol legally.

Need hobby motor help

I'm a bit clueless about the technical side of motors. I mean I know how they work and I know torque and speed and whatnot, but I'm looking for certain motors with a certain amount of torque. I'm looking for a motor than can lift approx. 20 pounds plus itself and 3 other motors that have equivalent amounts of torque. I have no clue what the Stall-torque rating is or how it's measured, so a crash course in that couldn't hurt, either. Help?

Techpod - The Hobby UAV Kickstarter launch!

Techpod is this really cool project on Kickstarter, its an Unmanned Aerial Vehicle (UAV) for amateurs and pro-level flyers who want to do FPV flying (First- Person-View). You'll find me (mhkabir98) at RCGroups and DIY Drones and I have been following this particular project for months and am very earnest for it to succeed. Techpod is a - "A high performance remote control airplane for first person view (FPV) flying and the Unmanned Aerial Vehicle (UAV) hobbyist. Designed from the ground up to have an enclosed pan and tilt camera mounted in the nose for a completely unencumbered point of view. All wrapped up in a super slick fuselage with high aspect ratio wings, a high efficiency airfoil and room to swing up to a 12 inch propeller." The designer, Wayne Garris is from Seattle, WA. I have known him for about a month now and would like his project to succeed. He works 50 hours a week to support his family and still finds enough time for designing UAVs. If anyone here is interested ,please support him by pledging something on his Kickstarter. You can get more info on Techpod at the website You can pledge whatever amount you want at his : Kickstarter Link An appeal to fellow instructablers to help Wayne can meet his $45,000 goal and start producing his Techpod kits for everyone across the world.

3V Hobby Motor in a 6V Circuit.

Hi. Hope I'm posting appropriately. If not, please forgive an older guy! I'm working on a Useless Box project that I power from a 6V wall wart. I've already completed one and it works great. I use two standard servos with an Uno. But now, rather than being satisfied, I'd like to add a 3V hobby motor, which naturally would only run randomly for short periods of time. I have purchased an AMS1117 step down module which is rated at 800mA from Amazon to get the correct voltage for my little motor. My question is, do I need to add a capacitor across the leads or to the casing. If so, how do I determine what size? And while I'm asking, is there anything else I need to think about? I appreciate any help as this is a new hobby for me.

hobby rocket using rocket candy

Today I tested a homemade rocket engine made with r-candy and clay catlitter (for the nozzle and plug). The nozzle was made from clay catlitter with a tapered hole I used about twenty grams of r-candy then l put a thin plug of catlitter. I had placed the rocket upside down on a bamboo rod clamped to a table with a scale under the engine but when I ignited it the sound was so great that I had to step back and could not get a reading but from the looks and sound of it the small 500 gram scale would be maxed out then at the end of the 3-5 second burn the thin plug at the end popped off shooting the engine up in the air this was becouse the core was not drilled all the way to the end so when the burn was near an end it found it easier to escape threw  the thin plug then the narrow nozzle.

Old hobbies die hard... some TRs

I had a lot of old pics to work off of so the building experience was a lot like what I remember loving about knex, without the frustration. This blaster (:>) has a pretty solid mech. The slide, anchored by the gray connectors on the naked black rods (hehe), requires the full motion to prime, resulting in the longest pin draw possible using this draw/anchor method. The pin I have on this has a rubber washer of sorts that I had laying around, so far working wonders. No broken pieces were required, though I slid a broken black rod that was conveniently the perfect length into the barrel construction. As I mentioned in the title, I built this just yesterday and I expect that it'll be further modified -- the grip was something I had lying around and could essentially just throw on, the stock was rushed. I was planning on building another and I'd be happy to make instructions if there's any demand, though these pics alone may be enough for the few of you. (8/24/15) Link to better quality pictures, really unimpressed by what got uploaded here... https://imgur.com/a/4y1Se Credit to KILLERK for the TR of course. I just gave it a new body. Update 8/25/15: 3D printed a piece for the front of the barrel. Update 8/27/15: Small changes all over. I'm okay with the front grip. There's some mole skin on the handle. Changed the below pictures to reflect what I currently have, clearer pics in the imgur album. Update 8/31/15 Finally got around to classing up the stock, quite happy with how it turned out. A few other changes as well, updated the pictures once more. Should be able to build from these pics!

What are the restirctions/requirements to play with model rockets in your country?

I wanted to start again with an old hobby of mine and buy some rocket motors and one or two easy rocket models. Just for the fun of seeing things to fly high and come down slow you know? Depending on which country you can call your residency now you might luagh about what happened to me: I went to first model building shop I could find nearby in my Yellow pages. Of course that had no clue about rockets, not even remote controlled cars as they only build build models for multiplayer board games. Next shop was selected a bit better with a focus on all things remote controlled. Here I was told that only a few shops actually sell any rocket related stuff due to the tough legal requirements of storage, handling and selling - WTF?? (excuse the language!) But at least I got an address for a shop that would be abe to help me figuring it all out. Last but not least I finally entered a shop filled with all sorts of model rockets, from simple to realist replicas of Saturn 5 engines. "Can I see your permit please?" "Do you have a club memebrship card stating you can buy engines?" "Can you provide the required details on your storage facilities and fire control system?" That were just a few of the questions thrown at me when I went to the checkout with 3 little rockets asking on where to find the engines and ingintion kits..... Turns out here in AU it is far easier to obtain a firearm and license than to get what you need to shoot a plastic rocket 100 or 200m high in the air.... Without being a member of a recognised model rocket club you won't have access to a legal launch area. Without your club permit you can't obtain a license required to buy a model rocket engine - yes we are taking about these paper tubes every kid uses.... Without the license, club membership and the required club permits you will never (legally) buy a rocket motor... To make things worse the 4 clubs I contacted only supply motors they buy to their members, at about 20% above market price of course and you won't get a card to buy your own until you are a member for at least three years... I already know in Germany and the US things are quite different but I would still like to know how exactly it works in your contry or if your face similar problems outside US and EU territory.

Hack your Servo V1.00: Make a powerful linear actuator using a standard hobby Servo

Hack your Servo V1.00: Make a powerful linear actuator using a standard hobby Servo   Provided you have the tools and the servo you can built this for under a couple of bucks. The actuator extends with a rate of about 50mm/min. It is rather slow but very powerful. Watch my video at the end of the post where the small actuator lifts 10kg vertically.   Materials List Tools list   - hobby servo - standard hobby brass tubing             -OD: 4.0mm, ID: 3.4mm             -OD: 5.8mm, ID: 4.5mm - standard hobby styrene tubing                                                 -OD: 4.8mm, ID: 3.5mm - M4 studding - 2 x M5 washers - 2 x M4 nuts - 5 minute epoxy - cyanoacrylate - grease - multi-strand cables - heat-shrink tubing   - standard tools – screwdrivers, scalpel, files etc. - dremmel multi-tool with ceramic abrasive disk, or similar - hand-drill + 4.9mm + 2.5mm drill-bits - M3 tap - M4 tap - soldering iron - glue gun - small vice - small saw - sanding paper (relatively fine) - small flame torch         http://www.01mech.com/sites/default/files/images/material_tools.jpg Procedure - I will be giving instructions based on the dimensional parameters of the Hitec HS-300. The procedure remains the same for any type servo. I strongly recommend you read the whole post before you start. So lets make a start, shall we?   - Open your hobby servo, remove control electronics, feedback potentiometer and mechanical stop on the servo’s output gear.   - Solder new cables on the servo motor’s leads.   - Drill two 4.9mm holes on the servo case bottom cover. These should be located longitudinally along the centre line and 9.5 mm from each end (this applies on the Hitec HS-300 and is also true for many standard servos but depending on your servo type there might be differences). The M4 thread will come out from the servo body using one of these two so this hole must be located directly below the centre of rotation of the servo’s output gear. Be very careful since this alignment is very important! If you don’t get it right you might have to use a new servo! The more accurate you are, the longer your servo will endure.     http://www.01mech.com/sites/default/files/images/bottomCover_potHead.jpg -  Measure the dimensions of the rotating shaft of the potentiometer on the servo’s original electronics – note the geometry in general. The shaft should be flattened right at the tip in order to prevent it from freely-rotating once inserted into the servo’s output gear.   - Take the M4 studding (M4 thread) pick one end and by using the dremmel and the abrasive wheel tool, replicate the tip of the servo’s potentiometer on that end. Start by decreasing the diameter of the thread, rotating it steadily by hand against the abrasive disk (normally to 3.5mm in diameter and at least 6mm in length). Try to think of your fingers as the chuck of a slow-turning lathe. Once the diameter of the thread is down to the pot’s shaft diameter, flatten the tip according to the potentiometer’s tip. The idea is that the thread must be inserted in the servo’s output gear in the same way the potentiometer did before. The better the fit the longer your servo will endure.     http://www.01mech.com/sites/default/files/images/thread_modofication.jpg - On the flat tip of the M4 thread, screw the two M4 nuts approximately 20mm down its length. Following that, insert the two M5 washers. - Insert the thread inside the servo and adjust the distance of the nuts and washers down the thread such that the servo case bottom cover closes properly and the motor rotates efficiently. Basically, you have to make sure that once the thread and the servo are assembled there is no pressure between the servo case bottom cover and the nut-washer assembly. Similarly, you have to make sure that once the thread and the servo are assembled there is no gap between the servo case bottom cover and the nut-washer assembly. Once again, the better the fit the more your linear actuator will endure.   - Once you find the optimum position carefully disassemble the servo, remove the washers from the thread and use a drop of cyanoacrylate on the side of the nut that was in contact with the washers in the assembly. Let the glue to settle for 5 minutes. Unscrew the second nut by 10mm towards the flat end of the thread, and prepare a small epoxy mix.   - Put the mix between the two nuts and screw the second nut back in place. Once in place also use some epoxy on the back of the second nut as well. Ideally you should sand all contacting areas before you apply the epoxy glue. Leave to settle for at least 6 hours (even if you use a 5 min epoxy).     http://www.01mech.com/sites/default/files/images/copper_thread.jpg - Secure tightly the 4mm diameter brass tube onto a vice by flattening the mounting end and use the M4 tap VERY carefully tapping as deep as possible (at least 15mm). Using the dremmel cut 10mm out of the threaded part of the tube and then verify that the created thread runs along the whole length of the small threaded tube by screwing it onto an M4 screw. Keep the 4mm threaded tube on the screw for handling purposes. Apply a layer of solder on the outside surface.     http://www.01mech.com/sites/default/files/images/thread_solder.jpg - Take the 5.8mm diameter brass tube pick one end and try to sand at least 5mm into the tube (on the inside). Mount the brass tubing on the vice without squishing it and apply a thin layer of solder on the inside.   - Ignite the flame torch, take the 4mm threaded tube (holding it by the screw) and move it on the soldered end of the 5.8mm diameter brass tube which should still be mounted on the vice. Using the flame torch heat-up both tubes and carefully insert the 4mm threaded tubing inside the 5.8mm tubing until is fully inside. Use a pair of pliers and insert the brass tube by holding the end of the screw that sticks out. Hold the threaded tube levelled inside the 5.8mm tube until the solder settles. If you do not have a flame torch use a candle, your soldering iron and your patience :). Remove the screw. The end result will be the cylinder of your linear actuator.     http://www.01mech.com/sites/default/files/images/thread_cylinder.jpg - The cylinder length should be equal to: the actuator’s desired working length (stroke) + length of the 4mm threaded tube which is inside the 5.8mm tube + 10mm for the mounting hinge at the cylinder end.   - The thread length should be: the actuator’s desired working length (stroke) + length of threaded tube which is inside the 5.8mm tube + length of the thread which resides inside the servo casing, which is model-dependant.   - Take the non-threaded/non-soldered side of the cylinder and drill a 2.5mm hole through, 5mm from the tip.     http://www.01mech.com/sites/default/files/images/cylinder_heatShrink.jpg - Cover the entire length of the cylinder with heat-shrinking tube and cut-off any excess bits. The 2.5mm through holes made earlier on the non-threaded side of the cylinder are now covered. Use the drill again to expose them and tap them through, using the M3 tap. Screw a 20mm long M3 studding or simply cut-off the head of a 20mm long M3 screw. This will act as your cylinder mounting hinge.   - Take the 4.8mm styrene tubing and M4 tap it 10mm deep. Cut a small ring 5mm in length and screw it in the M4 thread fully, from the side of the nut that was in contact with the washers (long side of the M4 thread). This will act as bushing between the thread and the servo’s case bottom cover. Ideally you should use nylon, copper or metal bushing.     http://www.01mech.com/sites/default/files/images/thread_servo.jpg - Secure the motor cables inside the servo casing using a glue-gun and use heat-shrinking tube to cover them. Assemble the servo including the thread, the styrene bushing and the washers.   - Screw-on the cylinder and you are good to go! Here is a video of the small actuator lifting 10kg For those of you that have watched my video on the MTR Rover     will understand where the idea of hacking the servo came from ;))   Soon we will be posting assembly instructions, code and schematics on how to modify a standard servo to get full PID speed and position control with 10-bit resolution over 360 degrees – continuous ;)     I look forward for your comments!

Any Sydney-ers here want to share art/craft/tinkering shopping spots?

I'm trying to compile a list of rather disparate resources that can be found in Sydney: hobby shops, art stores, gadget-component stores, etc. I'm looking for places that carry specialized or uncommon items like: Electronics parts (switches, capacitors, etc) Jeweler's size tri-wing screwdriver Loupe Small calipers Glass etching paste Soapstone Pencil torch Low-cost soldering iron (i.e. one that's not meant to be used often) Half-hard sterling wire Carbon fiber rods & others (I'm sure people who are more familiar with different crafts will be able to list tools/materials unique to their area, and I might as well try and collect a broad range of sources.) & Yes, I have looked online.

A little help

I've been looking for ways to make a little spending money. I've looked up a few things, and I was disappointed with the "generic" ideas, like garage sales and stuff.  One of my latest ideas is for a Ebay business. So my question is what should I sell? I know, I know, that's a big question.  Some of my interest are... Wood working ( Along with wood burning ) Outdoors ( Fishing, Hunting, Biking, Hiking ) Tinkering with mechanical objects Building little doohickeys off Instructables Any Ideas?

My 1950s Hobbies treadle fretsaw remade needs a new home.

Hi Folks. I recently obtained a rather more modern electric scroll saw at a bargain price and as space is at a premium in my little workshop my 1950s Hobbies saw is looking for a new home. I have considered offering in on one of the several the freegle groups I am a volunteer moderator of but as the Instructables community is close to my heart & I believe that there is almost certainly a maker out there eccentric enough to find it interesting to use I thought I would try to find it a home here first. It has obviously seen better days & isn't really up to fine limit work but I have had some fun using it & it is more than up to the job of roughing out work. I live in Hertfordshire England & as this thing isn't exactly a lightweight I really dont want to go to the hassle of trying to pack it for shipping so ideally it needs a home fairly close by, I dont have transport at the moment so whoever wants it would have to collect it themselves. If anyone is interested please dont be shy, let me know ASAP as I really dont relish the idea of it languishing at the back of my shed. It's going free so take the opportunity to give a loving home to a bit of maker history. All the best. NG.

Can I run different voltage LEDs off a 9V battery?

I have a small project that uses a 3 light LED list that runs off of 3 AAA (4.5V) batteries, but I also want to power a 12V LED string (for cars about 24" long) and I am uncertain the mA draw for either. This is for a follow-up to fine tune my son's 2014 Halloween costume. I run the 12V string off of 10 LR-44 batteries and get about 3 hours use out of these, so I know the mAh draw is relatively small. I'd like to extend the use of the 24" string. The 3 LED light goes for days on the AAA's.  Because both lights are used for the same application, I wanted to see if I could join them together in a single power source and power off of 1-9V or 2-9V (in serial for a total of 18V) batteries. I think my preference would be the 18V with an in-line resistor, but I do not know which resistor to use. Is this the correct approach? What are other alternatives?
