Hackaday Omnibus 2014 — Our First Ever Print Edition

January 19, 2015 by Mike Szczys 101 Comments

Here’s your chance to grab a tangible piece of Hackaday. This morning we are starting pre-orders for the Hackaday Omnibus 2014. This is our first-ever print edition. It collects some of the best original content published on Hackaday in 2014.

We’re proud of what the Hackaday crew accomplished last year. From stories of old and new to articles that encouraged you to stretch your hacking universe, we are thrilled with the original content articles we saw published last year. To go along with this top-tier content, we added amazing art and illustrations from [Joe Kim]. The product is something that demands commemoration in print and thus the Omnibus was born.

This full-color, 80 page, perfect binding volume is just what your coffee table has been crying out for. Of course it will look spectacular covered in solder and clipped resistor leads on the bench. And if your company is serious about hardware you need to send that message with a copy of the Omnibus in the reception area (or comically in the commode).

We are pricing the Hackaday Omnibus 2014 at $15 but we will sweeten the deal if you get in on the preorder. Use this coupon code to get $5 off: OMNIBUS2014. The coupon will work for the first 500 copies pre-ordered with an estimated shipping date of 2/9/15.

DIY Print Head Experiments

October 13, 2010 by Caleb Kraft 5 Comments

Inkjet printheads are a pretty rare thing to see done in home workshops. We would love to see more and got really excited when we saw this single nozzle, drop on demand, head being built. using a piezo disk intended to be a cheap buzzer and some reprap magic, [Johnrpm] got some results. [Madscifi] has been refining the design of the nozzle and the two have shared the process with us. Since it drops a single droplet of liquid, it can be used in a variety of manners, such as dropping plain old boring ink, or dropping a solvent into a powder for some 3d printing. You can see an example of the 3d printing in sugar above.

Make Your Own Toner Transfer Paper

July 12, 2010 by Jakob Griffith 17 Comments

Who would have thought that some corn starch could be made into toner transfer paper? We’re not sure of the advantages (perhaps its cheaper?), but if you have a lot of time or just love to get sticky [Matthew Sager] shows the proper method for making the paper, printing, and then etching a PCB.

If you’re just getting started making PCBs, we recommend you check out these DIY circuit etching videos to get a better grasp on the printing and etching steps.

How-to: DIYDTG

June 6, 2010 by Jakob Griffith 130 Comments

For those unaware, the little acronym above stands for Do-It-Yourself-Direct-To-Garment printing. In layman’s terms, printing your own shirts and designs. Commercial DTGs can cost anywhere from $5,000 to $10,000 which for the hobbyist who only wants a few shirts is ridiculous. So you would think this field of technology would be hacked to no end, but we’ve actually only seen one other fully finished and working DIYDTG. So we took it upon ourselves to build a DIYDTG as cheaply and as successfully as possible. Continue reading “How-to: DIYDTG” →

CES Update: CES Badges

January 9, 2010 by Devlin Thyne 8 Comments

In a previous post we had given one of our badges out to [Bre Pettis] at the MakerBot booth. We have been called the “Skull Guys” around CES and were stopped multiple times by people that did not know of this site. [Bre] got an extra of the size we are wearing around. [Leo Laporte] received the very first prototype which he promptly placed in his mouth. The badges are made from natural ABS plastic in [Devlin]’s CupCake CNC machine. There will be a post-CES follow-up with the release of the STL files to make the badge on Thingiverse as well as a step-by-step breakdown of the build process.

Direct-to-PCB Inkjet Printing

Full Spectrum Engineering has offered up a tutorial for their inkjet direct PCB kits that repurpose direct-to-CD capable inkjet printers (such as the Epson R280) to print etch-resistant ink straight onto copper clad board. This is easier and less error prone than some iron-on methods, especially for two-sided boards. Just print (no need to reverse the design), dry on a hot plate or in a toaster oven for a couple minutes, and your board’s ready for etching!

Homebrew methods exist for all of this, but for those who would rather move ahead with their design than spend time scrounging for the required bits, the kits offer a pretty good value. They can also meet you halfway…say if you’re only lacking access to a laser cutter and just want the CD stencil…all of the parts are available individually or as a complete set: the resist ink cartridge, the stainless steel board-holding stencil, and a supply of double-sided copper clad boards precisely sized for the stencil (3.5 by 2.5 inches). The small board size is well within the limits of the freeware Eagle Light Edition software.

Concerned about gunking up your nice inkjet with non-OEM ink? You can dedicate hardware to the job without breaking the bank. Many of the compatible printers are of the “free printer after rebate” bundle variety that can now be found inexpensively on Craigslist or eBay.
