Such a clever design, so much so that I copied it and printed it in 3D complete with the little ball inside the chamber. As I type this, an additional 10 copies are being printed so that I can give them to a group of 6 year old girls on the occasion of my neighbor's birthday party. Thanks for the inspiration!
This was an excellent tutorial. I did not find it wordy at all. Rather, the detailed descriptions you gave leave little to no room for error. I am fired up to build this one. I especially love the combination of wood and steel, a technique I have used myself. If I may be so bold, you may wish to consider powder coating the steel as this makes it impervious to rusting outdoors. The color range available is quite formidable, too.
Thank you so much! I'm going to give that an experimental try!
Thanks, Jordan. Let's just suppose that I wish to rewind the armature on a basic 3 volt can motor which have only simple plastic bearings. Are there formulas that allow me to predict what affect the number of windings and the gauge of the wire will have on the performance of the motor?One additional related question: does the precision of the wire wind, side-by-side as opposed to just wound round like a cord, effect the efficiency of a motor?Thanks for considering these questions. I've been repairing motors for years and have never found answers to these basic questions.
Was there any "formula" or just trial and error (which has served science and mechanics for millennia)? How did your modifications affect the service life of your modified motors?Thanks so much for your enlightening post!
Piggyback question; in the case of a simple DC case motor, such as the one shown above, can I just increase the gauge of the wire or the number of windings to be able to increase the speed of the motor? I do understand that higher rpms induce greater wear on the simple bearings.
In part two, can you discuss the factors which cause a given motor to operate @ a given voltage /current? I am thinking it is the resistance or impedence of the coils.
Masterfully created! The accompanying video is professional, informative, and concise. Your Instructable is worthy of any wizard's wand! I have it in mind to assemble this is Photoshop as one giant file and take it to a printer. I'll let you know how it works out! Thank you so much!Oh, I know how to simulate the footsteps...invisible, heat-activated, ink: http://www.wikihow.com/Make-an-Invisible-Ink-Messa... Make a footprint/character name stamp and mark out the trail. I wouldn't want to use flame, but a light bulb would certainly do the trick in a safe manner.
Thanks for that! I just finished assembling all the map pieces in Pshop. But, I'm going to use yours. The final piece is really quite large! I'm casting about for large parchment paper. I'll let you know if I can find any.
A great dollup of creative genius! Thanks so much for this! I just bought the clock mechanism off Ebay!.
Damned fine idea! I regret not knowing this before I replaced all my fluorescent tube lights with the expensive LED lights!
Very clever and effective use of materials.
