[Bunnie Huang] recently had the opportunity to do a thorough teardown of the new Formlabs Form 2 printer. It’s a long read, so just head over there and immerse yourself in every detail. If you want the cliff notes, though, read this but still go look at all the pretty pictures.
First, it’s a major upgrade with pretty much every component. The CPU is a huge step up, the interface went from monochrome to full color touch screen, the connectivity has been upgraded with WiFi and Ethernet, the optics are much better and safer, the power supply is integrated, there are lots of little improvements that handle things like bed leveling, calibration, resin stirring, pausing jobs, and resin refilling during a print. Bunnie practically gushes at all the features and impressive engineering that went into the Form 2.
You can compare the teardown of the Form 2 to [Bunnie’s] teardown of the Form 1 printer back in 2013.
This week’s Judge Spotlight focuses on [Andrew “Bunnie” Huang]. If you haven’t heard of him you need to pay more attention. His hacker cred goes way back to the original Xbox, which he reverse engineered and laid bare its security flaws. Maintaining his hacker spirit he went on to design and hack the Chumby. More recently he took on the challenge of developing and Open laptop called Novena. All of this while continuing to explore and experiment with all kinds of electronics, posting about his adventures for those of us that care about an electronics ecosystem that doesn’t shut out the user from tinkering with the hardware. Join us after the break for our conversation with The Hackaday Prize judge [Bunnie Huang].

Last month we mentioned [bunnie]’s Name that Ware competition where participants try to guess the functionality of a random bit of hardware. We thought you might want to see another example; pictured above is the June 2008 ware provided by [xobs]. You can see a high res version here and an image of the daughter card as well. Be forewarned that someone has already posted the solution in the comments. At first glance there are quite a few interesting bits: board is copyright 1991, the 8-bit ISA connector doesn’t have any data lines connected, just power, and it’s got a lot of analog circuitry. Take a guess and then check out the comments on [bunnie]’s site to see the solution.
Guessing games are fun, especially when unnamed hardware and prizes are involved. [bunnie] holds a Name that Ware contest on his blog once a month; he posts an image of hardware components like the PCB above (which is May’s mystery ware) and asks visitors to try to guess the machine it came from or at least its function. Aside from the prizes he gives out, winners get the most coveted of all rewards: bragging rights. He’s been running the monthly contest for quite some time and it’s not always PCBs; past wares have included this micron thickness guage (internal) and an xray of a crystal oscillator.
