What is better than a tool? Two. What is better than two? Two tools tooling together. [tintek33] wanted a rotary tool to become an attachment on his mini lathe, the video is also below the break. Fortunately, Dremels and Proxxons are built to receive accessories, or in this case, become one. Even if the exact measurements do not apply to your specific hardware, we get to see the meat of the procedure from concept to use.
We start with where the rotary tool should be and get an idea of what type of bracket will be necessary. The design phase examines the important dimensions with a sketch and then a CAD mock-up. Suitably thick material is selected, and the steps for pulling the tool from the raw stock are shown with enough detail to replicate everything yet there is no wasted time in this video. That is important if you are making a quick decision as to whether or not this is worth your hard work. Once the brace is fully functional and tested, it is anodized for the “summer ocean” blue color to make it easy to spot in the tool heap. Some complex cuts are made and shown close-up.
Thank you [jafinch78] for your comment on Take a Mini Lathe for a Spin and check out [tintek33] using his mini lathe to make a hydraulic cylinder for an RC snow plow.

Part of what makes flamethrowers fun is their inherent danger. This is what makes a lot of things fun, though, from snowboarding to skydiving to motorcycle riding. As with all of these sensible hobbies, though, it’s important to take as much unnecessary risk out of the activity as possible to make sure you’re around as long as possible to enjoy your chosen activity. With that in mind, [Stephen] decided to make some improvements on his classic wrist-mounted flamethrower.
To start, he ditched the heavy lead-acid battery that powered the contraption in favor of a smaller 5 V battery. In fact, the entire build is much more compact and efficient. He was also able to use the same battery to run a tiny taser that acts as an ignition source for the flamethrower’s fuel. The fuel itself is butane, and the modified flamethrower is able to launch flames much further than the original due to improvements in the fuel delivery system. These improvements also include “Finding a way to prevent butane droplets from lighting and landing on [his] hand” which seems like a necessary feature as well.
The entire build now is very well refined and professional-looking, which is also a major improvement from the first version. It’s also worth watching the video after the break as well, which includes a minor run-in with the New York City fire marshal. And, it still retains some of the danger and all of the fun of the original builds which is something we always like to see.

If you’re desperate for a sense of nostalgia for video games of yore but don’t want to shell out the big bucks for an NES classic, you can always grab a single arcade-style game that’ll plug straight into your TV. Of course it’s no longer 1980, and playing Space Invaders or Asteroids can get old after a while. When that happens, just replace the internals for an upgraded retro Atari 2600 with all the games from that system instead of just one.
As expected for something that has to fit in such a tiny package, this upgrade is based on a Raspberry Pi Zero. It’s not quite as simple as throwing RetroPi on it and calling it a day, though. For one, [Blue Okiris] is still using the original two-button controller/joystick that came with the Ms. Pac-Man game this build is based on, and that added its own set of challenges. For another, RetroPi didn’t have everything he needed so he switched to another OS called Recalbox. It also includes Kodi so it could be used as a media center as well.
The build looks like a hack in the truest sense of the word. The circuit board sticks out the bottom a little bit, but this is more of a feature than a bug because that’s where some extra buttons and the power switch are. Overall, it’s a great Retro Atari system that has all the true classics that should keep [Blue Okiris] entertained until Atari releases an official system one day. If you’d like to go a little deeper in the Atari world, though, you could always restore one instead.

Though Python 3 was released in 2008, many projects are still stuck on Python 2.
It’s understandable that porting large existing codebases to a new version is a prospect which sends a shiver down many a developer’s spine. But code inevitably needs to be maintained, and so when all the shiny new features that would fix everything are in a new version, is it really worth staying rooted in the past?
We’ll take you through some of the features that Python 2 programs are missing out on, not only from 3.0 but up to the current release (3.7).

When a hacker owns an oscilloscope, it’s more than a possession. Weary nights are spent staring at the display, frantically twiddling the dials to coax out vital information. Over time, a bond is formed – and only the best will do for your scope. So why settle for the stock plastic dials when you could go for gold? Well in case you hadn’t noticed, we’re partial to a bit of over-engineering here at Hackaday, and [AvE] has upgraded his Rigol scope by adding metal knobs.
Employing his usual talent in the shop, [AvE] first turns the basic knob shapes from the stock, before drilling them and milling the outer texture pattern at an angle. Voilà: six custom knobs for 100% more torque and traction control. No matter how trivial the project, it’s always good to watch him at work. This [AvE] video doesn’t come with the usual fruity language warning; instead this build is set to the swelling tones of Beethoven. “Less Talk – More Action!” says the title, but we have to say that we miss his quips. That said, he still manages to deliver his signature humour through action alone.
For some slightly more functional oscilloscope upgrades, you can read about adding a hybrid touchscreen interface, or hacking a Rigol scope’s software to unlock greater bandwidth, storage depth and more.

While Apple products have their upsides, the major downside with them is their closed environment. Most of the products are difficult to upgrade, to say the least, and this is especially true with the iPhone. While some Android devices still have removable storage and replaceable batteries, this has never been an option for any of Apple’s phones. But that doesn’t mean that upgrading the memory inside the phone is completely impossible.
[Scotty] from [Strange Parts] is no stranger to the iPhone, and had heard that there are some shops that can remove the storage chip in the iPhone and replace it with a larger one so he set out on a journey to try this himself. The first step was to program the new chip, since they must have software on them before they’re put in the phone. The chip programmer ironically doesn’t have support for Mac, so [Scotty] had to go to the store to buy a Windows computer first before he could get the chip programmer working right.
After that hurdle, [Scotty] found a bunch of old logic boards from iPhones to perfect his desoldering and resoldering skills. Since this isn’t through-hole technology a lot of practice was needed to desolder the chip from the logic board without damaging any of the other components, then re-ball the solder on the logic board, and then re-soldering the new larger storage chip to the logic board. After some hiccups and a lot of time practicing, [Scotty] finally had an iPhone that he upgraded from 16 GB to 128 GB.
[Scotty] knows his way around the iPhone and has some other videos about other modifications he’s made to his personal phone. His videos are very informative, in-depth, and professionally done so they’re worth a watch even if you don’t plan on trying this upgrade yourself. Not all upgrades to Apple products are difficult and expensive, though. There is one that costs only a dollar.
We sat down with him after his talk at the Hackaday Superconference last November, and we have to say that he made us think more than twice about tackling the tiny computer that lies hidden inside a cell phone. Check out his talk if you haven’t yet.

It can be disheartening when a favoured device begins to break-down. Afflicted by an all-but-dead battery and a fritzing-out hard drive, Redditor [cswimc] sensed the imminent doom creeping up on their 6th generation iPod, and responded by reviving and upgrading the decrepit device instead!
It’s no easy task to crack open one of these things, so they found themselves taking their time and carefully wedging the pry tool between the front and back covers, working their way around the exterior. Once separated, gingerly disconnecting the few ribbon cables allowed the iPod to be opened fully. From there, they turned to swapping out the original hard drive for an iFlash dual SD card board — one of the cards turned out to be a dud, but 128GB is still a step up from 80GB — and a new 3000mAh battery. Combined with replacing the power-hungry HDD, the battery life has been overwhelmingly increased over the original’s 650mAh capacity!
