Trinket Contest Update #2


Whoa nelly, the Trinket entries are really starting to rolling in fast now! The last update featured only five, but below you’ll find an even dozen, and there are more coming in as we write!

The contest asks you slap the Hackaday logo onto something for a chance at winning one of 20 Trinket dev boards donated by Adafruit for this contest.


[Adam] is showing a Skull and Wrenches struck with gigantism. He’s displaying this on his Epoch Clock which was hacked for use as a POV display.


Click to enlarge this image of a welding helmet. The third eye for [Robert] when melting metal to join two parts of a project surely needs to be the Hackaday logo.


We can’t fault [Mike] for sending in a project which we already featured a few years back. It’s a pen plotter build from old computer parts.


[Xeracy] is experimenting with panels that can be backlit to show a design. He 3D prints them and leaves the design portion thinner to let more light through.

trinket-conductive-inkThis offering is [Aston’s] take on building soft circuits. He printed the logo using conductive ink on cardstock.

Can we interest anyone in a spray paint stencil of our logo? [Carl] sized it in the Gimp, then printed it out and cut the stencil by hand.


[Matthew’s] entire blog post about milling a logo into a DSLR lens cap is worth reading no matter what shapes you’re trying to mill.

A little virtual work never hurt. This is [Jan-Hendrik’s] entry of a SketchUp version of the design.

[Steve] printed this on an inkjet. He admit’s it’s rather trivial but mentions he tweaked all the settings to get the best tiny print possible.


On track to be recognized for smallest entry is this logo etched on a key. [Kyle] pulled it off with an 8W YAG laser and needed a microscope to take a picture of the finished product.

This Arduino clone includes the logo on both sides. It was sent in by [Joel]

We though this was just another TV displaying the logo, but it turns out that [Kyle] has been editing the spashscreen logo on hotel televisions to show the logo whenever a guest turns on the TV.

  1. Here’s my entry. I think Abe looksgood with a skull and wrenches earring. Sorry for the blur. Crappy phone camera.

    1. It might be possible to get a little smaller on the inkjet, but not much. The thing is that most inkjets have an upper limit to the resolution of raster they’ll take in, one which is more in line with a photograph than binary artwork. In the case of the model I used (an Epson Workforce Pro WP-4530 this tops out a 600 pixels per inch. So even if I make the logo half the size I’ll just end up with something only 30 pixels across, probably a recognizable skull-and-bones but not beyond that. It’s been a while since I checked but Epson’s other product lines use resolutions that are multiples of 720 and so take in a 720PPI raster If I remember right. That’ll help a little, but not an order of magnitude. You’d probably still need to stick to pigment inks just to reduce the dot gain too. I’ve been playing around with better papers (this one was on plain paper, mostly as a joke), and on photo papers it comes out clearer (with a good render to work with you can see hints of the nose hole) but it’s still pretty limited by dot size.
      In theory going to vector might make an end run around the raster limit. Vectors would get processed by the driver itself, and might get converted directly to PCL nozzle commands bypassing the raster limit entirely. The problem is I’ve tried printing directly from Inkscape and it just feeds the paper and puts nothing on it. (There may be a way around that but Inkscape’s UI is so obtuse in places I haven’t found it yet.) I can’t go around Inkscape because I’m a degreeless, penniless, hobbyist and don’t exactly have access to other vector tools ATM.
