Recently [ETA Prime] felt a bit underwhelmed by the raw performance of his MacBook Neo when it came to running for extended periods under full load, such as when gaming. Thus the obvious solution is to mildly over-engineer a cooling solution that takes care of issues like thermal throttling. The Apple MacBook Neo with its […]
Laser Welding is apparently the new hotness, in part because these sci-fi rayguns masquerading as tools are really cool. They cut! They weld! They Julienne Fry! Well, maybe not that last one. In any case, perhaps feeling the need to cancel out that coolness as quickly as he possibly could, YouTuber [Wesley Treat] decided to […]
Embedding fasteners or other hardware into 3D prints is a useful technique, but it can bring challenges when applied to large or non-flat objects. The solution? Use a gap-cap. The gap-cap technique is essentially a 3D printed lid. One pauses a print, inserts hardware, then covers it with a lid before resuming the print. The […]
What did Elliot Williams and Al Williams read on Hackaday last week? Tune in and find out. After a bit of news, [Vik Oliver] chimes in with some deep PLA knowledge. Then the topic changed to pressure advance measurements, SDRs, making super-resolution PCBs with a fiber laser, and more. Want to 3D print wire strippers? […]
The people at Signal Snowboards are well known not only for producing quality snowboards, but doing one-off builds out of unusual and perhaps questionable materials just to see what’s possible. From pennies to glass, if it can go on their press (and sometimes even if it can’t) they’ll build a snowboard out of it. At […]
Isn’t there some claim events come in threes? After the extremely rare leak of the iOS Coruna exploit chain recently, now we have details from Google on a second significant exploit in the wild, dubbed Darksword. Like Coruna, Darksword appears to have followed the path of government security contractors, to different government actors, to crypto stealer. It […]
Love them or hate them, inkjets are still a very popular technology for putting text and images on paper, and with good reason. They work and are inexpensive, or would be, if not for the cartridge racket. There’s a bit of mystery about exactly what’s going on inside the humble inkjet that can be difficult […]
Flow batteries are rather unique. They generate electricity by the combination of two fluids flowing on either side of a membrane. Typically, this involves the use of some kind of pump to get everything moving. However, [Dusan Caf] has demonstrated another way to make a flow battery operate. [Dusan]’s build is a zinc-iodide flow battery. […]
Test tasting soda mead. (Credit: Golden Hive Mead, YouTube) You can certainly just chug down that bottle of soda you purchased, but if you accept the premise that the preparation of food and drink is just a subset of chemistry, and that chemistry is fun, then it naturally follows that using soda as the basis […]
A lot of the time, we must assign our own meaning to the numbers on the clock. 8:30 AM is work kicking off, 12 PM is lunch, and 5PM is when the corporate chains release us to what’s left of the day. If you’d rather the clock tell you what’s special about the current time, […]
