Friday Hack Chat: Open Source Silicon

This Friday, Hackaday.io will be graced with purveyors of Open Source Silicon. Join us in the Hackaday.io Hack Chat this Friday, April 14 at noon PDT (19:00 UTC) for a conversation with SiFive, an ‘Open’ silicon manufacturer.

This week, we’re sitting down with SiFive, a fabless semiconductor company and makers of the HiFive1, an Open Hardware microcontroller that you can just go out and buy. Late last year, SiFive released the HiFive1, an Arduinofied version of SiFive’s FE310 System on Chip. This SoC is a RISC-V core and one of the first microprocessors that is completely Open Source. It is …read more

Friday Hack Chat: Audio Amplifier Design

Join [Jørgen Kragh Jakobsen], Analog/digital Design Engineer at Merus-Audio, for this week’s Hack Chat.

Every week, we find a few interesting people making the things that make the things that make all the things, sit them down in front of a computer, and get them to spill the beans on how modern manufacturing and technology actually happens. This is the Hack Chat, and it’s happening this Friday, March 31, at noon PDT (20:00 UTC).

Jørgen’s company has developed a line of multi level Class D amplifiers that focus on power reduction to save battery life in mobile application without losing …read more

Friday Hack Chat: ASIC Design

Join [Matt Martin], ASIC designer at Keysight, for this week’s Hack Chat.

Every week, we find a few interesting people making the things that make the things that make all the things, sit them down in front of a computer, and get them to spill the beans on how modern manufacturing and technology actually happens. This is the Hack Chat, and it’s happening this Friday, March 17, at noon PDT (20:00 UTC).

[Matt] has been working at Agilent / Keysight since 2007 as an ASIC designer. The work starts with code that is synthesized into logic gates. After that, [Matt] …read more

Yes, You Can Reverse Engineer this 74181

[Ken Shirriff] is the gift that keeps on giving this new year. His latest is a reverse engineering of the 74181 Algorithmic Logic Unit (ALU). The great news is that the die image and complexity are both optimized for you to succeed at doing your own reverse engineering.

We have most recently seen [Ken] at work explaining his decapping and reverse engineering process at the Hackaday SuperCon followed soon after by his work on the 8008. That chip is crazy with complexity and a die-ogling noob (like several of us on the Hackaday crew) stands no chance of doing more …read more

Silicon Wafer Transfer Machine Is Beautifully Expensive

There’s nothing more freeing than to be an engineer with no perceptible budget in sight. [BrendaEM] walks us through a teardown of a machine that was designed under just such a lack of constraint. It sat inside of a big box whose job was to take silicon wafers in on one side and spit out integrated circuits on the other.

[BrendaEM] never really divulges how she got her hands on something so expensive that the engineer could specify “tiny optical fiber prisms on the end of a precision sintered metal post” as an interrupt solution for the wafer.  However, we’re …read more
