Straight line art - what is the technical name?

I remember back in 2nd, 3rd, 4th, and I believe even 5th grade, when I was in a gifted program, we had to draw. We drew only straight lines, and when we did it right, it made a curve. We would get a paper with 2 lines, connected at a vertex, at a 90 degree angle. We would draw points every centimeter or so, and connect the points, far to close, far to close. (It's hard to explain.) I'm searching for it on the Internet, but I can't seem to find the right word. Does anyone know it? Thanks, and if it turns out all good, expect an Instructable on it mid- to late October.

Help with Cleaning a Straigh-Razor

I found a straight-razor at the flea market the other day, so obviously I bought it. Now I'm wondering how I would go about cleaning and sharpening it? Does anyone know good metal cleaning tips for such a delicate blade? I know that you sharpen the blade before you intend to shave on a strop, or a piece of leather, but anything else? On the blade, it has: George Wostenholm & Son's Celebrated I-XL Razor Sheffield, England

Is it possible to make perfectly straight cuts with a jig saw?

I recently bought a 40 breeder tank and am working on a stand. I need to make about 19 perfect straight cut on 2x4's. I do not have a circular saw or table saw and the local hardware store does not make accurate cuts. Is there a jig I can make  to make perfect cuts with a jig saw. I was thinking like a box that guides the  2x4 and holds the jig saw in place.

need a jig for cuttin styrofoam straight/smooth surfaces?

I'm trying to get into lost foam (aluminum) casting, so I just build a styrofoam cutter ("frame" with a hot-wire). It's pretty difficult to handle because it melts trough the styrofoam so quickly and it's hard to hold perfectly straight and every movement makes an impression in the styrofoam part. I need some ideas on how to make a jig that makes it easy(er) to make smooth surfaces in the styrofoam part, I was thinking something that adjusts the distance between the hot wire and the table/surface and then just slide the styrofoam across the table/surface through the hotwire for making plates (easy), but I need to be able to change the distancee between the surface and the hotwire for different thinknesses but also somehow be able to make angles and hopefully also somehow ROUND PIECES AND CYLINDERS :o hope you can give me some inputs :D and even better some pictures, drawings and links thianks!

SnapLED powerd straight from 18650 or CR123A 3.7Volt battery?

So I don't know if you know about the red-orange SnapLED, but here is the information on it. http://www.philipslumileds.com/products/snapled#datasheets I want to power one of these with a 3.7 volt battery like a 18650 or CR123A. (or the 3Volt options) What is the most simple circuit I can use that will provide long life for my led? This led confuses me because it runs at 150ma (which is right on the boarder of High power leds) You have to treat High power leds usually more carefully than with just resistors. Will just resistors be sufficient for a 150ma led?

I raise composting nightcrawlers for fishing bait and worm castings.  I need to make a simple shaking machine with 3 different sizes of screens.  The first screen with keep all of the larger pieces of dirt and twigs from the compost and a few of the larger worms.    The second screen of a smaller mesh will keep most of the worms and a little of the unfinished compost.  The third and final screen will let through only the worm castings and the worm cocoons.  This machine should hold at least a five gallon bucket of compost at a time and the worms have already turned any large particles of garbage; leaves; dirt etc into small parts, but picking these worms out a few at a time is a very time consuming process and I have a lot of 50 gallon barrells to go through.

What causes oodammo to spin in certain guns, when other guns make them fly straight?

I've noticed, with guns like the MeZak, my new one and the V2, and a quite a few others, the ammo sort of spazzes out and flips around when fired, and isn't accurate. But with guns like the TBOS, Lowney's small oodammo pistol, etc. and TBAP the ammo flies straight. It's about 2 accurate ones for every one flippy one. Can someone explain why?

How do I power 1 watt leds, can these not be hooked up straight to a power source with an appropriate resistor? Answered

I have on ebay a number of cheap 1 watt leds, please see the pictures below.  Some look like large LEDs with perhaps thicker then normal anode and cathode leads coming out of them, others look like they are surface mounted onto a circular, flower shaped circuit board with possible multiple soldering point to apply power.  I am hoping to power 24 of the 1 watt LEDs off a modified computer power supply (I use these for powering everything that needs a bit more amperage).  LEDs are Forward Voltage: 3.2V~3.4V  Forward current: 350mA.  In some of these adds they refer to them also being able to supply the driver, is this a term for a power supply?  I was planning on running it off the power supplies 5v out with an appropriate resistor.  The all share the same forward current, while the forward voltage varies from 300mA to 350 mA.  Can I treat these as regular LEDs, mind you they will get quite hot I assume, or am I missing something?

Rectangular lines in Fritzing? Answered

Question by bertus52x11   |  last reply


Rectangle accuracy tip...

Well, I made a discovery when I was messing around with some shells, I found that if you load a red rod into your rectangle, then put a shell of 5 silver spacers all the way back on the red rod... The red rod then flies extremely straight. The shell then falls straight down, where you can use it again if you want. P.s. This also works for yellow, and grey rods.P.p.s. You can also do the same thing for oodammo, but with only one silver spacer.TRY IT OUT PEOPLE=P
