Screaming Circuits: Open Source

PROTOTYPE AND SMALL VOLUME
PCB ASSEMBLY MADE EASY

Top 5 Things to Know When Moving from Hand Assembly to Robotic Assembly

A lot of factors go into the decision to hand build or outsource circuit boards. I hand build my own sometimes, simply because I enjoy the challenge. Of course most of the projects I design are for my own use,... Read more

Arduinos Spotted

I've given a few talks at the various Embedded Systems Conferences on the subject of the Arduino as a real prototyping tool. I've designed and built a number of custom Arduino-compatible boards myself. I've become an advocate for the Arduino... Read more

PART 2, SCREAMING CIRCUITS AND THE MAKER COMMUNITY

My last post mused on the affordability of assembly at Screaming Circuits for the maker/very small business/kickstarter community. My hypothetical Arduino-compatible dual motor driver Kickstarter came out to $9.81 per board at a quantity of 250. That's probably more than... Read more

Part 1, Screaming Circuits and the Maker community

Yes, a Maker can get 250 custom-design Arduino-compatible boards built for about $10.00 each at Screaming Circuits. How can Screaming Circuits, a full-service assembly provider, compete with a low-cost assembly house? Upon first thought, it might seem like Screaming Circuits,... Read more

The Value of Open Source

There were a number of interesting sessions and debates last week at the DesignWest show. One of the more passion filled, was on the value of Open Source hardware. Some people think it will save the world,if only everyone will... Read more

Particle Update

I've been ignoring my Geiger counter for a while now, but I picked it back up and made some progress again. For some reason, I just wasn't getting the 555 based HV power supply to generate a high enough voltage.... Read more

Thru-hole to SMT

Thanks to a comment from Michael yesterday, I think everything is now cool with my Geiger counter. I had left the AT2313 default fuse setting at clock/8. That dropped the RS232 speed from 9600 to 1200 and it made the... Read more

Geiger Counter without the Muller?

My Geiger counter project has been on holiday for a while. When I originally ordered all of the parts, I ordered fuse clips (to hold the tube) with solder lugs too big to fit in the holes and a trim... Read more

Open Source. What is it Good For?

I've written about open source hardware (OSHW) a few times before. Like this and this. I've understood open source software for quite some time and over the last few years have been starting to get what open source hardware is... Read more

IS IT VALUE? IS IT PROTO?

Looks like it to me. I got a couple of nice PCBs from Sunstone here. The parts, except for the Geiger tubes are here from Digi-Key too. The tubes are someplace between the Ukraine and Canby. All I have left... Read more
