Zine Printing Tips From A Solopreneur

Zines (self-produced, small-circulation publications) are extremely DIY, and therefore punk- and hacker-adjacent by nature. While they can be made with nothing more than a home printer or photocopier, some might benefit from professional production while losing none of their core appeal. However, the professional print world has a few gotchas, and in true hacker spirit [Mabel Wynne] shares things she learned the hard way when printing her solo art zine.

As with assembling hardware kits, assembling a zine can take up a lot of physical table space.

[Mabel] says the most useful detail to nail down before even speaking to printers is the zine’s binding, because binding type can impact layout and design of an entire document. Her advice? Nail it down early, whether it’s a simple saddlestitch (staples through a v-shaped fold of sheets), spiral binding (which allows a document to lay flat), or something else.

Aside from paper and print method (which may be more or less important depending on the zine’s content) the other thing that’s important to consider is the finishing. Finishing consists of things like cutting, folding, and binding of the raw printed sheets. A printer will help arrange these, but it’s possible to do some or even all of these steps for oneself, which is not only more hands-on but reduces costs.

Do test runs, and prototype the end result in order to force unknown problems to the surface before they become design issues. Really, the fundamentals have a lot in common with designing and building kits or hardware. Check out [Mabel]’s article for the full details; she even talks a little about managing money and getting a zine onto shelves.

Zine making is the DIYer’s way to give ideas physical form and put them into peoples’ hands more or less directly, and there’s something wonderfully and inherently subversive about that concept. 2600 has its roots in print, but oddball disk magazines prove one doesn’t need paper to make a zine.

Massive Aluminum Snake Casting Becomes Water Cooling Loop For PC

Water cooling was once only the preserve of hardcore casemodders and overclockers. Today, it’s pretty routinely used in all sorts of performance PC builds. However, few are using large artistic castings as radiators like [Mac Pierce] is doing. 

The casting itself was inspired on the concept of the ouroboros, the snake which eats its own tail if one remembers correctly. [Mac] built a wooden form to produce a loop approximately 30″ tall and 24″ wide, before carving it into the classic snake design. The mold was then used to produce a hefty sand cast part which weighed in at just over 30 pounds.

The next problem was to figure out how to create a sealed water channel in the casting to use it as a radiator. This was achieved by machining finned cooling channels into the surface of the snake itself. A polycarbonate face plate was then produced to bolt over this, creating a sealed system. [Mac] also had to work hard to find a supply of aluminum-compatible water cooling fittings to ensure he didn’t run into any issues with galvanic corrosion.

The final product worked, and looked great to boot, even if it took many disassembly cycles to fix all the leaks. The blood-red coolant was a nice touch that really complemented the silvery aluminum. CPU temperatures weren’t as good as with a purpose-built PC radiator, but maxed out at 51 C in a heavy load test—servicable for [Mac]’s uses. The final touch was to simply build the rest of the PC to live inside the ouroboros itself—and the results were stunning.

We’ve featured a few good watercooling builds over the years. If you’ve found your own unique way to keep your hardware cool and happy, don’t hesitate to notify the tipsline!

2025 One Hertz Challenge: A Discrete Component Divider Chain

Most of us know that a quartz clock uses a higher frequency crystal oscillator and a chain of divider circuits to generate a 1 Hz pulse train. It’s usual to have a 32.768 kHz crystal and a 15-stage divider chain, which in turn normally sits inside an integrated circuit. Not so for [Bobricius], who’s created just such a divider chain using discrete components.

The circuit of a transistor divider is simple enough, and he’s simply replicated it fifteen times in surface mount parts on a PCB with an oscillator forming the remaining square in a 4 by 4 grid. In the video below the break we can see him measuring the frequency at each point, down to the final second. It’s used as the timing generator for an all transistor clock, and as we can see it continues that trend. Below the break is a video showing all the frequencies in the chain.

This project is part of our awesome 2025 One Hertz Challenge, for all things working on one second cycles. Enter your own things that go tick and tock, we’d live to see them!

Compass CNC

Human In The Loop: Compass CNC Redefines Workspace Limits

CNCs come in many forms, including mills, 3D printers, lasers, and plotters, but one challenge seems universal: there’s always a project slightly too large for your machine’s work envelope. The Compass CNC addresses this limitation by incorporating the operator as part of the gantry system.

The Compass CNC features a compact core-XY gantry that moves the router only a few inches in each direction, along with Z-axis control to set the router’s depth. However, a work envelope of just a few inches would be highly restrictive. The innovation of the Compass CNC lies in its reliance on the operator to handle gross positioning of the gantry over the workpiece, while the machine manages the precise, detailed movements required for cutting.

Most of the Compass CNC is constructed from 3D printed parts, with a commercial router performing the cutting. A Teensy 4.1 serves as the control unit, managing the gantry motors, and a circular screen provides instructions to guide the operator on where to position the tool.

Those familiar with CNC routers may notice similarities to the Shaper Origin. However, key differences set the Compass CNC apart. Primarily, it is an open source project with design files freely available for those who want to build their own. Additionally, while the Shaper Origin relies on a camera system for tracking movement, the Compass CNC uses four mouse sensors to detect its position over the workpiece.

The Compass CNC is still in development, and kits containing most of the necessary components for assembly are available. We’re excited to see the innovative creations that emerge from this promising new tool.

This Week In Security: Sharepoint, Initramfs, And More

There was a disturbance in the enterprise security world, and it started with a Pwn2Own Berlin. [Khoa Dinh] and the team at Viettel Cyber Security discovered a pair of vulnerabilities in Microsoft’s SharePoint. They were demonstrated at the Berlin competition in May, and patched by Microsoft in this month’s Patch Tuesday.

This original exploit chain is interesting in itself. It’s inside the SharePoint endpoint, /_layouts/15/ToolPane.aspx. The code backing this endpoint has a complex authentication and validation check. Namely, if the incoming request isn’t authenticated, the code checks for a flag, which is set true when the referrer header points to a sign-out page, which can be set arbitrarily by the requester. The DisplayMode value needs set to Edit, but that’s accessible via a simple URL parameter. The pagePath value, based on the URL used in the call, needs to start with /_layouts/ and end with /ToolPane.aspx. That particular check seems like a slam dunk, given that we’re working with the ToolPane.aspx endpoint. But to bypass the DisplayMode check, we added a parameter to the end of the URL, and hilariously, the pagePath string includes those parameters. The simple work-around is to append another parameter, foo=/ToolPane.aspx.

Putting it together, this means a POST of /_layouts/15/ToolPane.aspx?DisplayMode=Edit&foo=/ToolPane.aspx with the Referrer header set to /_layouts/SignOut.aspx. This approach bypasses authentication, and allows a form parameter MSOTlPn_DWP to be specified. These must be a valid file on the target’s filesystem, in the _controltemplates/ directory, ending with .iscx. But it grants access to all of the internal controls on the SafeControls list.

There’s an entire second half to [Khoa Dinh]’s write-up, detailing the discovery of a deserialization bug in one of those endpoints, that also uses a clever type-confusion sort of attack. The end result was remote code execution on the SharePoint target, with a single, rather simple request. Microsoft rolled out patches to fix the exploit chain. The problem is that Microsoft often opts to fix vulnerabilities with minimal code changes, often failing to fix the underlying code flaws. This apparently happened in this case, as the authentication bypass fix could be defeated simply by adding yet another parameter to the URL.

These bypasses were found in the wild on July 19th, and Microsoft quickly confirmed. The next day, the 20th, Microsoft issued an emergency patch to address the bypasses. The live exploitation appears to be coming from a set of Chinese threat actors, with a post-exploitation emphasis on stealing data and maintaining access. There seem to be more than 400 compromised systems worldwide, with some of those being rather high profile.

Transparent PCBs Trigger 90s Nostalgia

What color do you like your microcontroller boards? Blue? Red? Maybe white or black? Sadly, all of those are about to look old hat. Why? Well, as shared by [JLCPCB], this transparent Arduino looks amazing.

The board house produced this marvel using its transparent flexible printed circuit (FPC) material. Basically, the stuff they use for ribbon cables and flex PCBs, just made slightly differently to be see-through instead of vaguely brown.

The circuit in question is a Flexduino, an Arduino clone specifically designed to work on flexible substrates. It looks particularly good on this transparent material, with the LEDs glowing and the white silkscreen for contrast. If you like what you see, you can order your own circuits using this material directly from JLCPCB’s regular old order form.

Most of all, this project reminds us of the 1990s. Back then, you could get all kinds of games consoles and other electronics with transparent housings. There was the beloved PlayStation Crystal, while Nintendo did something similar with the N64 while adding a whole line of tinted color and charcoal versions too. Somehow seeing a bit of the inside of things is just cool. Even if, in some cases, it’s just to avoid smuggling in prisons.

It took decades before you could get custom PCBs quickly and easily. Now, board houses are competing for the enthusiast (consumer?) market, and competition is spurring development of crazy stuff like transparent and even glow in the dark PCBs. What next? We’re thinking edible, ROHS and WEEE be damned. Drop your thoughts in the comments.
