Toward a Truly Open‑Source Printer
I’ve spent the last 3 weeks delving into printing and how they work. I started this with a very general understanding with knowing little difference between print technologies, laser, inkjet etc etc. What brought this on was a need for a printer and having an understanding of printing where I knew printers follow the economics of razor blades, so not wanting to get ripped off had me delve deep. And what I found is: laser printing is mechanically, and economically superior to inkjet technology. For most documents laser is much cheaper, and prone to failure by a far less degree than inkjet printing, this is of course discounting image rendering. Inkjet is hostile to openness by design: why? - Precision fluid dynamics - micro-level XY motion of both paper and print head - chemically specific inks - and extremely fragile print heads In particular, HP cartridges and other brands that now follow in HP’s footsteps, marry both the print head and the cartridge into one consumable item. They are temperamental to ink, heat, and use as they are made to be thrown away. This is not conducive to the hacker ethos of experimentation. The Raspberry Pi team released an “HP Killer” that depends on HP cartridges. This, while a step in the right direction, is still locked into an ecosystem many of us wish to escape. The printer is dependent on the throwaway print heads, will only accept inks made to spec. Laser printing is a better foundation for open source printing. Why? - Distinct elements – toner, drum, optics, and fusing - Less tolerance dependence (fine toner powder rather than liquid ink) - Less moving parts (mono) - Simple deterministic logic Toner size can vary unlike chemical makeup of liquid inks. Toner is also cheaply available at larger quantities. An open sourcing of laser printing: could be to marry both the philosophies of 3D resin printing and laser printing, keeping the toner, the heated roller and forgoing the laser and drum in place of an array of electrodes, similar in principle to an LCD. The open source community understands LCD technology, it’s matured, software solutions exist already, this makes it easier to drive than a prism firing a laser at a drum. Selecting pixels on the electrode array to charge, dusting toner then placing a sheet of transfer medium (paper) atop to then roll a heated roller over will bind the toner to the paper. We have thus printed something. Sadly I’m no coder or an engineer, but the issue of printing in the open source community has been a frustration before and especially after my heavy research of printing. So if this idea is useful I want it to be out there even if it’s only useful in inspiring someone to take a different angle at this problem. This project won’t revolutionise printing, I doubt it could even print at a legible standard for office use. But mechanically, it lends itself to the hacker/tinkerer space. It allows wide tolerances, experimentation that won’t brick a print head and is understandable to the general community.-------
A simple image cut/paste app!
Here’s a fun experiment for Android users: Try to cut & paste (or collage) 2 images on your phone. Go to the Play Store and find an app that can do this simple task. Guess what? All the apps that do this are AWFUL ad-filled garbage. Almost unusable. Can someone please make a simple FOSS app to cut/paste images on Android?
cyclical calendar: a #FOSI that i hope already exists or is in process somewhere
linear time freaks me out ive been dreaming of a circular calendar that follows the moon cycle, the seasons, allows for constellation visuals to follow astrological events, wheel of the year celebrations, and can be stripped down to just that or gage up with traditional dates, weeks, months, etc. ive seen plandisc [https://plandisc.com/en/] so I know some are considering this as an effective tool, to see time this way I truly despise linear, square calendars they suck the life out of my life let me know if you’ve seen or heard of anything ☆

Fosi Audio i5 Review
Something a bit different from Fosi Audio with the recent launch of their new full-sized open-back planar headphones called the i5.
Worth the money? James finds out in his full review, now published on Headfonics!
A mounted under the desk pump that vents the hot air from PC outside.
A PC is pretty much a space heater these days. Which is not great when it gets all hot and humid outside. Many suggest just getting a small AC but why not remove the heat from it’s source and put it outside? I imagine the vent being much smaller than the big AC tube pictured.
