this is a clever piece of up cycling. Since i always use filament from the same manufacturer, i just rely on weing my spool before a long print.
this really useful. An actual piece of test equipment that does not have a uproc in it. Still an arduino could provide scale conversion and data logging among other features.Great instructable! Thank you.

what if you have a guest and need a second cup of tea!! Fun stuff.
I like the idea of using this as a light for an umbrella rig, or other bounce lighting techniques. Can this led be strobed?
i admire your willingness to "BOLDLY GO...."
ummm yeah, this isn't going into my test equipment file but a good safe project for young school kids.

This has inspired me to build a custom harness using a pair of meters i already own that i would not want to glue together. I will use pomona banana plugs and jacks for the input to the individual meters and the input to the paired meter rig.While not as economical as the great solution you present it preserves the fuctionality of the meters i have .Thank you for a well written instructable.
Beautiful looking display. But not much spectrum information it seems to display more time duration than spectrum, and the repetitive tinkly music was spectrally limited and frankly annoying to listen to.
excellent disciplined approach to engineering and design. I wish you the best in your carreer.
I agree the frame work is needed and that a box made 1/4 " mdf would be hard to fasten. So this is not a criticizim.You could take the frame pieces and fasten the strips of wood to the back side of the panels with glue and short brads this allows work against a solid surface. After the glue dries the panels would be easier to fit together without risk of the frame racking . The point here is that if the panels pull an out square frame into alignment the frame will possibly not fit tightly into the corners and the case will not be as strong.Thanks for your post.
I appreciate the experimental spirit. But i must call you out on the very naive and shortsighted assumptions you have made. The recent coverage of the Samsung battery fires should serve as a warning about the energy potential these compact and powerful batteries have. Samsung got it wrong TWICE with the original and the replacements and their resources for test far exceeds yours.

While this is not something I will build, I hold your creative thinking in very high regard. I am inspired to follow my own creative ideas on my to do list . Thank you for following your instincts to an impressive conclusion.
imho you might want to go with larger diameter guide rods or upgrade to block and track linear bearings. Wonderful project overall!!

Hey no need to apologize for not making the most efficient motor! You did well. The instructable was clear and well written. Some one looking for a good science fair project or teaching model would benefit from this.Here are some suggestions:Use hot glue instead of foam,less messy. Use washers on the bottom of the field support rods to reduce the size difference between the rod and coupling to make it easier to keep the rods straight.Fix the rotor to a shaft.Set bearings into the rotor support to make the motor able to drive something. No criticizim here, just a way to drive home the point if this is built for demo purposes.Thank you.
A welder is not likely to work as they are very high CURRENT but low voltage, the exact opposite of what is being demonstrated here.
Would it suit your design objectives to use an external control scheme ? I'm thinking that if the "armature" mounted some Nd magnets and the commutator operated a polarity reversing relay feeding the coils and there were another set of coils on the opposite side.........Hmmmm.I noted that you took your welding ground thru the workbench when welding to the first wheel hub and then to the sprocket segments for the other welds . Did the workbench ground damage the bearings ?
