Heart mold from homebrew silicone
Greg comments on his difficulties with the stiff consistency of the cornstarch / caulk mixture, which seems like a germane time to mention a comment on last night’s Oogoo post from W. Aaron Waychoff, who claims to have had success using glycerine as an additive instead of cornstarch. [Thanks, Greg, and Aaron!]
How-To: Make cheap castable silicone from caulk
Turns out, though, that mixing in some cornstarch accelerates the drying process; just how much depends on how much starch you add. The author recommends starting with a 1:1 mix. I’m not sure about his explanation that the process works because the hygroscopic starch carries moisture into the internal volume of the silicone, but in any case there are probably other additives that will accelerate the process as well as or better than cornstarch. You might even find one that’s not opaque and allows for translucent castings.
Polly the housetruck
Pollymecca the housetruck pulled up in front of MAKE headquarters earlier this week, and she was lovely. Inspired by gypsy caravans and British “living wagons,” maker John Labovitz set out to create a house on wheels complete with a workspace for his projects in photography, programming, and research. His website lays out all the technical […]
Printable molds for casting monolithic button arrays of any size
Josef Průša saw last week’s post about choosing a silicone for casting soft button arrays and pointed me to his printable mold for such arrays on Thingiverse. The model was produced in Clifford Wolf’s awesome OpenSCAD 3D modeling package, and the .scad script is available for download with the Thing. It has been parametrized to produce molds of button arrays having any number of rows and columns–all you have to do is change two values. The individual buttons are sized to match the SparkFun 2×2 button pad used on the monome, and also include backside recesses for LEDs.
Make a knife from an old saw blade
Ever since I made my first ninja throwing star in metal shop class, I’ve always wanted to make my own knife. But I was put off by the notion of having to acquire the furnace, anvil, leather apron, and handlebar mustache requisite for forging a proper tempered blade. So, instead I decided to make a utility knife by cutting out a pattern from a circular saw blade, using my Dremel Rotary Tool.
Mini-documentary about the desks of creative people
