RC2014 Homebrew Z80 Computer Kit… now in After Dark!

fustini, , Leave a comment

The RC2014 is a Z80 based modular homebrew.  The designer Spencer Owen recently did a version with our After Dark service (clear solder mask on black substrate) and it is available on Tindie:

Limited Edition RC2014 Mini After Dark

Special edition Z80 based retro computer kit with stunning After Dark PCB

Fundamentally, this is an RC2014 Mini. A single board Z80 computer that runs BASIC or Z80 assembly code. If you are looking for an easy to build, good looking, well supported Z80 single-board computer, you probably should just go and buy a RC2014 Mini

However, if you are after a stunning looking Z80 single board computer which is one of only 25 in the world, then read on…

Automatic Component Tape Cutter For When Your Electronics Kit Hits The Big Time

fustiniLeave a comment

Even for the simplest of products, production at scale can be big challenge. For example, you might find yourself spending many hours manually counting and cutting strips of component tape to go with the DIY electronics kit your selling on Tindie. [Tom Keddie] found himself in similar position some time ago, and built himself an automated component counter and tape cutter.

Every last Saturday of March there is International Open Hackerspace Day!

Screenshot from 2020-02-07 14-21-59

What could you do?

  • make a press release and spread this around your (local) newspapers, websites etc. (include nice hires pic with people on it)
  • explain the word ‘hacker’ and maker (some people have still a negative / criminal interpretation of hackers)
  • show people around your space and explain what a hackerspace is.
  • give an workshop eg soldering, programming, arduino
  • give a ‘lecture’ about privacy, IoT (and lack of security), open source software.
  • any more ideas? Add them here.

Participating spaces are:

Netherlands:

Brazil

Bulgaria

Check hackerspaces.org see to more as they are added!

Back in December, I visited Nicolas Collins at the School of the Art Institute in Chicago and got to see one of the latest creations that he is using in class. The beautiful traces wind their way into the classic LM386 audio amp for an expressive overdriven effect:

Nicolas Collins is well known for having written Handmade Electronic Music: The Art of Hardware Hacking:

… provides a long-needed, practical, and engaging introduction to the craft of making – as well as creatively cannibalizing – electronic circuits for artistic purposes. With a sense of adventure and no prior knowledge, the reader can subvert the intentions designed into devices such as radios and toys to discover a new sonic world. At a time when computers dominate music production, this book offers a rare glimpse into the core technology of early live electronic music, as well as more recent developments at the hands of emerging artists. In addition to advice on hacking found electronics, the reader learns how to make contact microphones, pickups for electromagnetic fields, oscillators, distortion boxes, and unusual signal processors cheaply and quickly.

Lead-Free Solder Alloys: Their Properties And Best Types For Daily Use

fustiniLeave a comment

Lead-free solder alloys have been around for as long as people have done soldering, with sources dating back about 5,000 years. Most of these alloys were combinations like copper-silver or silver-gold and used with so-called hard soldering. That’s a technique still used today to join precious and semi-precious metals together. A much more recent development is that of soldering electronic components together, using ‘soft soldering’, which entails much lower temperatures.

Teardown 2020

Teardown is about the practice of hardware: prototyping, manufacturing, testing, disassembling, and circumventing, all while having fun. Leave the marketing glitz and talk of venture capital at the door and come prepared to learn and teach.

Helen Leigh wrote a great Hackaday post about what happened at Teardown 2019!
