Reverse engineering silicon is a dark art, and when you’re just starting off it’s best to stick to the lesser incantations, curses, and hexes. Hackaday caught up with Ken Shirriff at last year’s Supercon for a chat about the chip decapping and reverse engineering scene. His suggestion is to start with an old friend: the 555 timer.
Ken is well-known for his work photographing the silicon die at the heart of an Integrated Circuit (IC) and mapping out the structures to create a schematic of the circuit. We’re looking forward to Ken’s talk in just a few weeks at the Hackaday Superconference. Get a taste of it in the interview video below.
If someone suggests you spend time working on boring projects, would you take that advice? In this case, I think Kipp Bradford is spot on. We sat down together at the Hackaday Superconference last fall and talked about medical device engineering, the infrastructure in your home, applying Sci-Fi to engineering, and yes, we spoke about boring projects.
Kipp presented a talk on Devices for Controlling Climates at Supercon last year. It could be argued that this is one of those boring topics, but very quickly you begin to grasp how vitally important it is. Think about how many buildings on your street have a heating or cooling system in them. Now zoom out in your mind several times to neighborhood, city, state, and country level. How much impact will a small leap forward have when multiplied up?
We’ve seen FDM printers lay down layers by extruding plastic in a line. We’ve seen printers use sintering and lithography to melt or cure one layer at a time before more print medium moves into place for the next layer. What we’ve never seen before is a printer like this that builds parts from distinct layers of substrate.
At the International Manufacturing Technology Show last week I spoke with Eric Povitz of Impossible Objects. The company is using a “sheet lamination process” that first prints each layer on carbon fiber or fiberglass, then uses a hydraulic press and an oven to bake the part into existence before bead-blasting the excess substrate away. Check out my interview with Eric and join me below for more pictures and details.
Every year at Supercon there is a critical mass of awesome people, and last year Sophi Kravitz was able to sneak away from the festivities for this interview with Katherine Scott. Kat was a judge for the 2017 Hackaday Prize. She specializes in computer vision, robotics, and manufacturing and was the image analytics team lead at Planet Labs when this interview was filmed.
You’re going to chuckle at the beginning of the video as Kat and Sophi recount the kind of highjinks going on at the con. In the hardware hacking area there were impromptu experiments in melting aluminum with gallium, and one of the afternoon’s organized workshop combined wood and high voltage to create lichtenberg figures. Does anyone else smell burning? Don’t forget to grab your 2018 Hackaday Superconference tickets and join in the fun this year!
Below you’ll find the interview which dives into Kat’s work with satellite imaging.
Scotty Allen has a YouTube blog called Strange Parts; maybe you’ve seen his super-popular video about building his own iPhone “from scratch”. It’s a great story, and it’s also a pretext for a slightly deeper dive into the electronics hardware manufacturing, assembly, and repair capital of the world: Shenzhen, China. After his talk at the 2017 Superconference, we got a chance to sit down with Scotty and ask about cellphones and his other travels. Check it out:
The Story of the Phone
Scotty was sitting around with friends, drinking in one of Shenzhen’s night markets, and talking about how bizarre some things seem to outsiders. There are people sitting on street corners, shucking cellphones like you’d shuck oysters, and harvesting the good parts inside. Electronics parts, new and used, don’t come from somewhere far away and there’s no mail-ordering. A ten-minute walk over to the markets will get you everything you need. The desire to explain some small part of this alternate reality to outsiders was what drove Scotty to dig into China’s cellphone ecosystem.
The Trenton Computer Festival (TCF) doesn’t have the name recognition of big technology conferences like DEF CON or HOPE. It’s not even as well known as smaller more localized conferences like DerbyCon, ShmooCon, or the Hackaday Superconference. In fact, there’s a good chance that most readers have never even heard of TCF. But despite not holding a place in the hacker lexicon, TCF has plenty to boast about. Its played host to technology luminaries from Bill Gates to Richard Stallman, and now in its 43rd year, holds the title as the longest continually running technology festival in the world.
When originally conceived in 1976, the show was devoted to the dawning age of the personal computer, but since then has evolved into a celebration of technology as a whole. When TCF kicks off on March 17th, there won’t be a media blitz or huge corporate sponsorship. There won’t be a simultaneous online stream of the event, and the only badges worn by speakers or attendees will be of the paper variety.
What you will find at TCF is a full schedule of talks given by people who are passionate about technology in its varied forms. These run the gamut from quantum computing to lock picking, from Arduino to Space Shuttle avionics.
At the heart of TCF is co-founder and current Chair Dr Allen Katz. I recently had the opportunity to speak with Dr Katz about the challenges of running a conference of this type, and the secret to keeping relevant in a wildly changing technology landscape.
While down here there’s room for debate about the suitability of 3D printing for anything more serious than rapid prototyping, few would say the same once you’ve slipped the surly bonds of Earth. With 3D printing, astronauts would have the ability to produce objects and tools on-demand from a supply of inert raw building materials. Instead of trying to pack every conceivable spare part for a mission to Mars, replacements (assuming a little forward thinking on the part of the spacecraft designers) can be made to order out of the stock of raw plastic or metal kept on-board. The implications of such technology for deep space travel or off-world settlement simply cannot be overstated.
In the more immediate future, 3D printing can be used to rapidly develop and deploy unmanned spacecraft. Tiny satellites (referred to as CubeSats) could be printed, assembled, and deployed by astronauts already in orbit. Innovations such as these could allow science missions to be planned and executed in months instead of years, and at a vastly reduced cost.
