We’ve seen a lot of Trinket builds over the past few months, but so far few people have capitalized on the Trinket’s minimalism. It’s a fairly simple circuit, as far as dev boards go, and with careful planning can be built entirely on perfboard. That’s what [villeki] did, with a project he calls Shrinket.
After looking at the schematic for the Trinket, [villeki] figured he could best the very small footprint of this ATtiny85 board. To do this, he mounted the uC on the bottom side of the board, bending the pins so they could be easily soldered to the pins. The only real challenge in building this tiny board was the USB connector. To fit this connector on board, the copper pads were carefully scraped off the protoboard and wires run to the zeniers.
The Shrinket is impressively small – only 0.6″x 0.9″ – and a very impressive example of soldering skills. If you’re looking for a project to hone your free-form soldering skills, this is a great way to spend an hour or two. Bonus, you probably already have the parts required (or a reasonable substitute) sitting around.
The ugly blobs of excessive solder is another, though not so impressive, example of soldering skills
Beg my pardon for the sarcasm, didn’t realize it is a proto board.
In that case, something very similar to this could also be a good project to hone one’s pcb etching skills.
Realy this is much better triket / digispark clone http://www.ebay.com/itm/321298227959?var=&ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 all in one solution, rgb led, relay driver, no shield req.
I do like the design – although the trinket is more easily breadboardable, and everyone seems to prefer the digispark libraries.
if you want this is more breadboard friendly than digispark or trinket, libraries are also compatible http://www.ebay.com/itm/321304411339?var=&ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
Nice work, may borrow that idea sometime for my own one off projects.
