Entry-level oscilloscopes are a great way to get some low-cost instrumentation on a test bench, whether it’s for a garage lab or a schoolroom. But the cheapest ones are often cheap for a reason, and even though they work well for the price they won’t stand up to more advanced equipment. But missing features don’t […]
The user interface of things we deal with often makes or breaks our enjoyment of using a device. [Janne] from Fraktal thinks so, he has an espresso machine he enjoys but the default controls were not what he was looking for and so in true hacker fashion he took what was and made it his […]
No doubt many readers have at times wished to try their hand at blacksmithing, but it’s fair to say that acquiring an anvil represents quite the hurdle. For anyone not knowing where to turn there’s a video from [Black Bear Forge], in which he takes us through a range of budget options. He starts with […]
If your shop comes complete with a MIG welder, an acetylene torch, and an air hammer, then you have more options than most when it comes to removing broken bolts. In this short video [Jim’s Automotive Machine Shop, Inc] takes us through the process of removing a broken manifold bolt: use a MIG welder to […]
This short video from [ProShorts 101] shows us how to build a variable speed disc sander from not much more than an old hard drive. We feel that as far as hacks go this one ticks all the boxes. It is clever, useful, and minimal yet comprehensive; it even has a speed control! Certainly this […]
With vector network analyzers, the commercial offerings seem to come in two flavors: relatively inexpensive but limited capabilities, and full-featured but scary expensive. There doesn’t seem to be much middle ground, especially if you want something that performs well in the microwave bands. Unless, of course, you build your own vector network analyzer (VNA). That’s […]
[Chris Cecil] had a problem. He had a Manncorp/Autotronik MC384V2 pick and place, and needed more feeders. The company was reluctant to support an older machine and wanted over $32,000 to supply [Chris] with more feeders. He contemplated the expenditure… but then came across another project which gave him pause. Could he make Siemens feeders […]
If you’re into electronics you can never have too many digital multimeters (DMMs). They all have different features, and if you want to make multiple measurements simultaneously, it can pay to have a few. Over on his video blog [joe smith] reviews the new Brymen BM788BT, which is a new entry into the Bluetooth logging […]
It started when [Mitxela] was faced with about a hundred incorrectly-placed 0603 parts. Given that he already owned two TS101 soldering irons, a 3D printer, and knows how to use FreeCAD (he had just finished designing a custom TS101 holder) it didn’t take long to create cost-effective DIY soldering tweezers. Two screws allow adjusting the […]
We’ve got a love-hate relationship with discount tool outlet Harbor Freight: we hate that we love it so much. Apparently, [James Clough] is of much the same opinion, at least now that he’s looked into the quality of their outlet strips and found it somewhat wanting. The outlet strips in question are Harbor Freight’s four-foot-long, twelve-outlet […]
