    Light Following Robot

    Google the work of Rodney Brooks. He has written extensively and intriguingly on subsumption architecture in robotics in which light seeking (photophilic) and light avoiding photophobic behaviors can be modeled using NO microcontroller and only a few photocells and transistors. Your project would benefit from using a left and right photocell to controll the base drive to transistors which would vary their conductance in response to or lack of available light.Good post.Neil

    Dont sell yourself short! Most people could not design a working machine out of cardboard. I have the advantage of being a licensed Autodesk inventor user and thats all i really know personally. Make your base plate from wood, since it is too large for most printers. Then all you need to design is a single "L" shaped bracket with a short leg that has two holes for mounting and a large hole with a rim to accurately locate your bearing . Print four copies of that and you would be ready to go. The H shaped frames in the cardboard version would not be necessary because the plastic would be more rigid.The L bracket idea should be within reach of your developing abilities, in short order :)Good luck.

  • Plywood Icosahedron and the Other 4 Platonic Solids

    Your work is beautiful. The math portion was interesting. Heres a potential solution for those with a more limited miter saw based on complementary / supplementary angles.If one were to cut a 45 degree angle into a piece of stock and then attach a piece at right angles so the right angle was clamped against the fence and the 45 degree part is against the table, the workpiece would be referenced to the 45 degree cut, then the miter saw would need to hit 24 degrees to make a 69 degree miter cut. Making such a jig would need to incorporate work holding and is beyond the focus of this instructable. You would need to include the necessary safety features so you dont hold the workpiece by hand while making the cut.I hope this helps.Neil

    Card Reading Shop Power Switch

    I drew inspiration from this. I have a 10 HP three phase converter that runs my 3 major machine tools. I will modify the design you presented to sequence a start relay which is needed to engage the starting capacitors in the phase converter which then should be bypassed once the phase converter is up to speed and before the major machinery is turned on.The solid state relay idea is fine but you could have remedied the spike with a back emf suppression diode across the relay, an optoisolator to drive the coil and if need be a snubbing cap across the contacts. I know this sounds much more complex than the solution you went with and I am not criticizing you, but solid state relays are expensive in the ratings I require , plus I already have the contactor.

The question I have is since you have a 3d Printer, Why not just print the parts?The one bad idea you mentioned is using a potentiometer to control motor speed, unless of course you were going to use a PWM scheme to control your motor. A simple pot circuit would waste power as heat.Good post. Thank you.

    Please make clear distinction between "welding" which involves melting the underlying metals being joined at thousands of degrees and soldering which a low temperature process at about 650 deg fahrenheit does not melt the metals being joined only the solder. There is no welding in this project.

    World's Simplest Electric Train

    i am a long time fan of K& J magnetics and a customer. The magnet stuck to the negative end of the battery is obviously going to stick quite well, but the positive end could possibly come out of position and increase friction due to the much smaller size of the positive terminal.Why not put a small steel washer big enough to fit over the positive end that is smaller than the battery's outer diameter and stick the magnet to that, to provide a more stable base and more mass for the magnet to stick to?I hasten to add that i have not built this as yet, so this is just appoint of of conjecture on my part.

    30 KVA Induction Heater

    The supplied schematic is excellent as is the source listing for the parts. This is a very complete instructable. My interest in inductive heating stems from a desire to solve a technical problem where in a 1/2 inch stainless steel rod is "locked" in place by galvanic corrosion to an aluminum tube. The area has limited access so I will need to fabricate a flexible link to the coil to get the coil around the desired assembly. I do not imagine I will need anywhere near the power this unit is capable of for this application, since I am essentially trying to exploit the different rates of expansion between the Stainless rod and the aluminum tube, not melt anything!!The greater capabilities will be of use in my machine shop at home.Thank you,Neil

    the ingredients are not toxic but neodymium magnets are NOT for young children. They are brittle and if they are allowed to fly together they can chip and spark and the chips are sharp. There have been some serious problems with kids swallowing small neodymium magnets which attract to each other through intestinal walls requiring surgical intervention.Given the relatively fluidity of this compound you could work with ceramic magnets. They are less powerful in a given size, cheaper and relatively safer than neodymium

    I might have had better results running it on a 9 volt battery and putting into a metal enclosure with the antenna sticking out but the circuit exhibited poor noise immunity when assembled on to a solderless breadboard I actually got a better result by eliminating the first stage and connecting the antenna to the second stage. I must add that I was working with this unit in front of my laptop and around some test gear on my bench so the circuit may just have picked up on ambient noise since it is not filtered.Thank you for the post.

    One method to isolate a non isolated variac which I used years ago to make a servicing rig for my bench was to take two identical beefy STEP DOWN transformers i had laying around and wiring them back to back low voltage to low voltage sides.

  • Rino Route Belt Drive Large Format CNC Router

    Another thought is the idea of reducing radiation by twisting the wiring going to the steppers using a variable speed drill. This will help with inductive radiation. These ideas have helped on 3d printers I have built. With a machine as large as the one you built, the runs are much longer so the capacitive and inductive coupling has more "plate" area or more turns through which to couple inductive noise.Best,Neil

  • POV Globe 24bit true color and simple HW

    I believe you misunderstood my last question. I not concerned how much current the spinner motor draws. Im trying to figure out if the upper bearing could be replaced by a motor which is being spun by the rotation of the ring and used as a generator to supply power to the rotating electronics in the ring .The shaft of the generator is fixed to the frame. The body of the generator is attached to the rotating ring so that as the ring is spun up, the generator could supply power instead of putting voltage through the bearings.I look forward to hearing from you.

    I saw this, collected it and downloaded it , i havent actually studied it yet !! I havent searched instructables specifically for propeller projects but you have inspired me to do so. Keep up the great work. I have a idea . If the upper bearing were replaced by a brushed dc motor mounted inside the rotating ring and the shaft were fixed to the frame the motor would become a generator driven by the spin motor and thus supply a dc voltage to the display and micro controllers. Because the mass is centrallized balance would not be affected, however driving a load with the generator would increase the mechanical load for the spin motor. Could you provide current measurements for just the rotating part of the display? I havent done the math but i think the idea may have merit.
