Balsa wood

Is there a way to make balsa wood stronger? I was thinking I could put a layer of wood glue on it and let it soak in but I wanted to know what you all think.

Rubber Band Gun Made out of Cardboard?

Would anyone know how to make a rubber band gun like the one made by Vat19 here?: http://www.vat19.com/dvds/bandit-guns-pump-action-semi-automatic-rubber-band-gun.cfm I imagine making it would be fairly easy, but finding what pieces to cut out would be a challenge. The pieces probably would probably made out of thick cardboard preferably. (because cardboard is easy to get)

Recommendations for online vendors of laser cutting materials?

Our makerspace has a few people who are thinking about placing one or more orders for various materials.  Most will be used on the laser cutter, but not all.  Some of the materials we are looking for are: * Wood: basswood sheets, birch (or similar sturdy) plywood, etc * Acrylics * Leather (vegetable tanned) * Paper: undetermined cardboard and/or cardstock What companies are out there that would have a variety of these materials at good prices?  (For comparison, we have been mostly leaning on the local Michaels - probably one of the most expensive options per-piece.) Thanks!

R/C Sailboat

I want to make a R/C sailboat, so far I have 4x32x1/4 inch balsa wood planks and they should last me the entire project. This weekend I'm going to visit a hobby store and get: waterproof wood glue, waterproofer for the wood. Then go to target and get a rotary tool. The boat will be 3 inches tall with a 1 inch keel (keeps the boat from tipping) 5 inches wide and 15 inches tall. I will get a cheap multi directional R/C car and use the steering mechanism to move the rudder and the drive motor to turn the sail. Once I make the boat I'll fill the gaps with wood paste and water proof everything hopefuly with a silicon based sealant. Any tips or flaws with my plans, please see the attached sketch.

Now transform this!

This is the most useless piece of wasted technology ever; the "men's groomer" "as seen on tv" !!!!!! I've bought two of these, planning to build from them something more useful, that is a circular etcher / drill and a sort of sliding saw, to etch / smooth / saw materials like hardened paperclay, glass, balsa wood and terracotta; but surely I've presumed to be smarter than I'm in electronics..... So I'm stuck with these two pieces of useless stuff in hand; do you know how to get an etcher and a saw from these? I'm sure there're many smart guys here. This may be one of the smartest instructables ever.

Covering

I am building a Sig Tiger rubber band-powered model. I know it's wimpy, but I don't have a budget for anything larger, or a place to fly it. My question is if anyone has experience with model airplane covering. Specifically, I read an article in an old RC Modeler magazine that said plastic wrap, attached with a glue stick, made excellent covering for light models, but that Monokote and Ultrakote will crush light balsa models when it shrinks. Has anyone ever tried this? I'm supposed to use tissue, according to the plans, but ew.Also, I have an ancient U-Control Waco SRE biplane that my uncle built when he was deployed to Korea. It has an old O.S. Max III 35 that has no hope of running again, but I want to at least recover it. Any suggestions for removing old covering? It seems to be Monokote-type stuff.

Hallowe'en competition - free idea for somebody.

I just had an idea for hallowe'en that I have neither the time nor the resources to do, but somebody else might.This would work best if your front door is some distance from the street, maybe with a creaky wooden porch to cross.Rig a fake wooden front door with a long inch-wide slot, top-to-bottom.Fill the slot in with a strip of something fragile (styrofoam? balsa? papier mache?). Maybe disguise the strip with smeared bloody hand-prints (especially round the door handle)Render a chainsaw "safe" (having never used a chainsaw, I don't know if this is possible - take the teeth off? replace the chain with a rubber belt?)When somebody rings the bell, start the chainsaw behind the door, give it a couple of revs and then cut through the fragile strip, laughing like a happy psycho.If the visitors are still there, stick one crazed eye up at the door and yell trick or treeeaaaat?Afterwards, mop the urine and faeces off your front step, replace the fragile strip, and settle back to wait for the next victim.

Witnessing Human Flight

First posted here. Last Friday, I drove up to Maryland to see UMD's Gamera II human-powered quadrotor. They are currently pursuing the Sikorsky Prize, established in 1980. Here's the team testing a new control system. http://youtu.be/3B2of4V35d0 (sorry, the embed function isn't working)   During this test, Gamera II flew for approximately 65 seconds, unofficially tying the endurance record that the team previously set. This flight time, plus the ability to remain within a specific boundary, satisfies two requirements of the Sikorsky Prize. Because the rotors are so close to the ground, the helicopter is benefiting from a cushioning effect of the air between the rotor blades and the ground. This effect will diminish exponentially when the team attempts sustained flight at the required 3 meters. The helicopter transfers the pilot's pedal power by unspooling cable from pulleys, mounted on the shafts of each of the four rotors. Flight time is limited by the pilot's stamina and the amount of cable stored in each pulley. The rotors are constructed of carbon fiber, balsa, and foam, and are covered in a plastic film.  All in all, it was a cool experience. I've never seen so much carbon fiber in my life! I look forward to seeing the team win the Prize.

unfinished,5 DOF Robotic Mechanical ARM

5 DOF Robotic Mechanical ARM Required Material of project:- 1. Basic Servo Tower pro 9g*4 2. Header pins Male female*2 3. Arduino Nano*1 4.10kΩ Resistor resistance*2 5. Trimmer Potentiometer track Linear; maximum resistance 10kΩ*4 6. Tactile push button*2 7. Blank circuit board*1 8. Acrylic strips for Robot & potentiometer body*2 9. Wires, Button, Switch 10.Balsa wood, Metal, Plastic Procedure:- Arrange all necessary items.. Please go through the attached images  for better understanding.. I divide whole project in two parts 1) Servo Motor assembly 2) Potentiometer assembly 1) Servo motor assembly: – Servo motor as J1, J2, J3, J4 fix the servo motors as shown in image use 3M tape to glue servo, use thin flexible plastic strip to make griper, make hole in center of each finger tie thread in that hole pass this thread from center hole and tie knot at the other end of thread with 4th servo motor’s knob, as you stretch thread finger get close vise versa. Fix whole arrangement on strong rigid base. 2) Potentiometer assembly: – Fix potentiometer as shown in figure name potentiometer as do previous R3, R4, R5, R6 this time place R6 separately for easy access this potentiometer control gripper to pick and place. Potentiometer arrangement symmetry must be same as servo arm. Fix whole arrangement on strong rigid base. Moving a little bolt from one side to the other side:- 1. Actuators / output devices: 4 micro servos 2. Control method: controlled by a PIC16F690       assembler firmware 3. CPU: PIC16f690 micro controller 4. Operating system: self made assembler code 5. Power source: 4.8V to 6V from 4 battery cells 6. Programming language: PIC Assembler 7. Sensors / input devices: teach in system with                         4 potentiometers       Making Processer:- The Potis are standard types and are screwed to the white plastic parts with their nuts. The axles are pressed into the transparent plastic part. The handle to move the teach-in-arm is a M3-Spacer and the socket is a plastic part with is normally used to fix balloons on a stick to hold it.                     move the motor itself by hand a little force is needed due to its permanent magnets, which create a small holding force. But inside the servo a lot of gears increase the force which you have to apply. If you move the servo by hand, you have to apply a much higher force. If you overcome the motors holding force, it starts to rotate an acts as a flywheel. So moving a servo by hand needs a high torque and its not easy to turn it to the position where you want it. ( Fan control modules for engine cooling of real cars have some extra parts to clamp the voltage which is generated, when you drive at higher speeds. In that case the fan works like a windmill and creates higher voltages than normal inside the power stage of the module.) And there were also a lot of other "problems" which had to be solved using my PIC Controllers. i.e. self made electronics for a RC-Excavator which works similar to the digital system used in slot cars. To replace a lot of wires between the rotating part of the excavator and the track unit, a small PIC 12F629 reads the pulses from up to 5 channels of a RC-Receiver and leads their information via a 2 wire connection to a second PIC12F629. At the second board the power is separated from the data. The PIC is reading the data, and generates the PWM output for the 5 Servo output connector. the 2 wire connection is made with a cheap 6,3mm mono microphone plug which is also used as the axle for the rotating part. The arm of the excavator is also powered by standard servos and so it was necessary to change the control behavior from proportional to integral so that the servos move like real hydraulic cylinders which are controlled by valves. I used the same 12F629 type for that job and added some features like adjustable limit positions and starting point programmable by one jumper, and automatic return to park position when missing the pulses for some seconds. The Software is simple:- Its working like a servotester for four axis. That means, every poti is connected to an analog in of the controller and all servos are connected to GPIOs. The controller reads each poti, does some scaling, so that the angle of the poti equals to the angle of the axis and finally he creates the PWM output 1-2ms pulse every 20ms for all servos. Teach mode:- After a reset the robot arm follows the teach in arm while simple mapping the analog inputs every 25ms to the servo motors. Pressing the button stores each servo position in a array. Play mode: The sketch reads the array step by step and moves the robot arm. For cool looking movements I added a routine calculates different micro steps for each servo to have moving start and end sync on all axis. Also added a ramp for soft increase/decrease velocity. Shorter travel distances the robot does slow, longer distances with faster speed.           The program moves the servos at full speed to the next position and a short delay time after each command allows all of the servos to reach their final position. That means that it is possible to increase the speed a little bit more by doing some fine tuning of the delay times after each command. The final thing which is still not implemented is the routine which saves the "Teach In" data 5 or 10 times per second, so that the controller is able to replay it in a loop with the original speed or with a lower or higher speed. Electrical Connection:- Provide separate power supply (5V DC 1amps) to the Servo motors . Don’t forget to short ground of both power source ( arduino + servo) 5 DOF Robotic Mechanical ARM :- 1. Use of Fiber on upper side 2. wooden spoon is a part of side body 3. cable tie *12 pieces use the robotic. 4. Some pices of wires 5. use scraw*4 6. Glue 7. some small clips Because to attached body 8. small size of plastic box 9. One pieces of  square fiber stand and one pieces small & medium  circular fiber  10.  L293D Motor Driver IC+IC Base KG143 11. Generic Elementz High Quality Nickel Plated 24*18 Points Bread Board*(2 pieces) and one plastic 12. Push Button Switch. Play Mode version 1.1 The gripper input is used to set the delay (0,1,3,15,60,300 seconds) after a loop is done. The switch (it was left from the project start) pauses the robot.        Thanks you:
