  • The Most Awesome-est Mid-Century-Modern Lamp Post Light Project

    Where did you purchase the LED light ? You didn't specify in the parts list. Another variation would be to use Photo-cells on the outside of the shade making the lamp solar powered. This really makes the project universal to mount any where without the need to run any wires for power.

    The Ultimate PVC Quadcopter

    Hey BenC165 - Excellent suggestion here. I went to the site and saw this as well as the other variations of the electrical junction box(es). This really gives a lot of flexibility not to mention durability to any DIY project. Thanks - Foxtrot70

  • How to Make Mini CNC 2D Plotter Using Scrap DVD Drive, L293d Motor Shield & Arduino

    It appears that the micro-tipped marker would be enough for etch resisting, I have used this type pen to touch up a board before etching. If not I think using another pen it can be disassembled, using rubber gloves and some care, remove the absorbent medium wash out the ink and reload it with the etch resisting ink. Replace the cap when not in use to prevent drying thus prolonging its life. Once done it should take right off. This would be excellent for rapid prototyping of PCBs .

  • How To Make The Mini Metal Foundry

    I agree, if the same crucible is being used by "cwix09" is as described in the article he should be ok. BUT, in all cases... BE VERY CAREFUL !!! If in doubt STOP until you have more info and/or ALL of your questions are answered. No one takes better care of you than... YOU.

  • How To Make The Mini Metal Foundry

    CWIX09 - I forgot to mention before the induction heater type is an electric type. You also might find this Instructible on induction heating helpful.http://www.instructables.com/id/12KW-Induction-Hea...

    Since you live in an urban area a really "clean foundry" option you might consider is an "Induction HEATER Foundry". A steel crucible can still be used as with the charcoal or propane/natural gas types, steel melts at 2500F / 1371C and Aluminum melts at 1218F / 659C. There are various Instructibles on Induction heating that can be up-scaled to the size of this charcoal unit. Also there are various videos on YouTube showing Induction melting techniques on a smaller scale for small quantities of melting gold, silver, etc. I Hope this is of use for you.

  • Interface a rotary phone dial to an Arduino

    jayne15 - With a rotary to DTMF or Touch Tone converter if you need Operator / Attendant, you would dial 0 (zero) the circuit would convert the pulses to the appropriate tones and the system would then dial thru. The same goes for "press 1 for... or Press 2 for... " the converter circuit counts the pulses and the generates the tone desired. Here is a link to a device that does just that, this is it costs about $45. You install it under the base cover of the phone Hope this helps. http://www.oldphoneworks.com/rotatone-pulse-to-tone-converter.html
