Acrylic Peg Pad

UPDATE: Now available for purchase here!

I asked Theo Gray to make me this 9.25 x 12″ acrylic peg pad (as opposed to peg bar) so I could do some quickie pencil animations on my glass drawing board, which I use as a cheap light table (see photo above).

Peg pad with punched graph paper under punched plain paper, in case I want grid lines for reference.

Instead of the traditional acme animation pegbar, which requires expensive pre-cut animation paper or/and a $500 hole punch, I wanted 3 round pegs that would line up with a standard inexpensive 3-hole punch. I specified clear acrylic, so I could scan drawings through it, so they’d stay in perfect register.

For larger drawings I rotate the peg pad on the scanner, but then I have to also rotate the resulting images, and I was impatient when I took these photos.

It works great. It’s small, light, and simple. I punch holes in cheap printer paper and off I go. Here’s a thing I made with it, inspired by Preston Blair:

Clearly this could be better, but it’s the fault of the animator, not the peg pad. I need to practice my hand-drawn animatin’ to improve. Now I can!

We can make more of these peg pads if it looks like there’s enough demand to sell 5 to 10 of them. Would you buy one for $20? If so, we’ll make them and put them on the e-store. What say ye?

Velomobile shifting diagrams

I made these to illustrate the difference between shifting a Rohloff vs. conventional derailleur/cassette system in a velomobile going at speed. According to Doug Davis at Bicycle Evolution, some novice velonauts desire Rohloffs because they offer a very wide gear range, but the larger gaps between gears make them less efficient at speed. He has data about watts and gear inches and rotations per minute, but I merely tried to convey the drama of having to upshift too fast in a 60+ pound tub:

Rohloff hub: Shifting over 14% at speed puts sudden stress on the velonaut.

For contrast, the illustration below represents a more narrowly spaced conventional rear cassette setup, like what I have on my Mango:

Conventional derailleur/cassette: Shifting in smaller increments reduces stress and maintains efficiency at speed. The velonaut’s cadence slows only slightly after shifting, and quickly returns to normal.

Maybe we’ll talk about this, and other recumbent nerd stuff, on the next Laidback Bike Report.

Banner Yet Wave

Animating waves does not come naturally to me. I covet the skills of animators who do them well, so when I recently found myself staring at the animated gifs of Felix Colgrave, I thought, “I wish I could do that.” Then I thought – hey, maybe I can. Thus, using repeating waves as guidelines:

I made this:

It may not look like much to you, but for me, it is an achievement, promising more interesting possibilities to come.

“Prayer” animation

Today I made this little straight-ahead hand-drawn pencil animation on a little 3×5″ pad. I was trying to give myself a little break from screens. You can see some eraser shreds got caught in the scanner; hopefully they add folksy charm.

Update: Someone on Neenster.org asked,”If we run it backwards, is it a creation myth?” You tell me:
