In this week’s edition of, ‘why you should care that Behringer is cloning a bunch of vintage synths’, I present to you this amazing monstrosity. Yes, it’s a vertical video of a synthesizer without any sound. Never change, Reddit. A bit of explanation: this is four Behringer Model Ds (effectively clones of the Moog Minimoog, the Behringer version is called the ‘Boog’) stacked in a wooden case. They are connected to a MIDI keyboard ‘with Arduinos’ that split up the notes to each individual Boog. This is going to sound amazing and it’s one gigantic wall of twelve oscillators and it only cost $800 this is nuts.
Tuesday is Fastnacht day. Fill your face with fried dough.
The biggest news this week is the release of a ‘folding’ phone. This phone is expensive at about $3000 list, but keep in mind this is a flagship phone, one that defines fashion, and an obvious feature that will eventually be adopted by lower-cost models. Who knows what they’ll think of next.
It’s a new Project Binky! This time, we’re looking at cutting holes in the oil sump, patching those holes, cutting more holes in an oil sump, patching those holes, wiring up a dashcam, and putting in what is probably the third or fourth radiator so far.
Here’s a Kickstarter for new Nixie tubes. It’s a ZIN18, which I guess means an IN18, a tube with a 40mm tall set of numbers. This is the king of Nixie clocks, and one tube will run you about $100. Nah, you can also get new Nixies here.
The Sipeed K210 is a RISC-V chip with built-in neural networks. Why should you care? Because it’s RISC-V. It’s also pretty fast, reportedly 5 times as fast as the ESP32. This is a 3D rendering test of the K210, with all the relevant code on the Github.
I’m not sure if everyone is aware of this, but here’s the best way to desolder through-hole parts. Heat the solder joint up and whack it against a table. It never fails. Hitting things is the best way to make them do what you want.
If you are in the market for a high-quality soldering iron, a rewarding pursuit can be attending dispersal auctions. It is not unusual to see boxes of irons, as anything remotely iron-like is bundled up together by the auctioneer into a lot with little consideration for what combination has been gathered. [Stynus] found himself in this position, the proud owner of a Weller DSX80 desoldering iron from an auction, but without its accompanying solder station required for it to work. Fortunately, he had another Weller solder station, not suitable for the DSX80 as it stood, but which provided a perfect platform for a home-made Weller DSX set-up.
The old station had a side-mounted valve and a 24V input, so he had to install a toroidal mains transformer and move the valve frontwards. Fortunately, this style of Weller station case was frequently available with just such a transformer installed, so there was plenty of space in the enclosure. A custom board was then created for a temperature controller centered upon a PIC microcontroller, and a new front panel was crafted to accommodate a Nokia 5110-style LCD display.
The resulting unit with its upper half repainted, is a pleasing and professional-looking project. Heated desoldering irons are an extremely useful tool that anyone should consider for their arsenal, but not all of them are as good as this Weller-based one. We recently reviewed a much cheaper example, with comedic results.
This unholy lovechild of a cheap solder sucker and an even cheaper soldering iron is the HBTool HB-019 desoldering iron. It came to me for the princely sum of five pounds ($7). So for somewhere between the cost of a pint of foaming ale and the pub’s pie and mash I’d eat alongside it, what had I got?
Regular Hackaday readers will be familiar with my penchant for ordering cheap tools and other electronic gizmos from the usual suppliers of Far Eastern tech, and subjecting them to review for your entertainment and edification. Sometimes the products are so laughably bad as to be next-to-worthless, other times they show enough promise to be of use, and just occasionally they turn out to be a genuine diamond in the rough, a real discovery. This is no precious stone, but it still makes for an entertaining review. Continue reading “Reviewing the HBTool HB-019 Desoldering Iron: It Probably Won’t Shock You”
[Joey] was about to desolder something when the unthinkable happened: his iconic blue anodized aluminium desoldering pump was nowhere to be found. Months before, having burned himself on copper braid, he’d sworn off the stuff and sold it all for scrap. He scratched uselessly at a solder joint with a fingernail and thought to himself: if only I’d used the scrap proceeds to buy a backup desoldering pump.
Determined to desolder by any means necessary, [Joey] dove into his junk bin and emerged carrying an old pump with a broken button. He’d heard all about our Repairs You Can Print contest and got to work designing a replacement in two parts. The new button goes all the way through the pump and is held in check with a rubber band, which sits in a groove on the back side. The second piece is a collar with a pair of ears that fits around the tube and anchors the button and the rubber band. It’s working well so far, and you can see it suck in real-time after the break.
We’re not sure what will happen when the rubber band fails. If [Joey] doesn’t have another, maybe he can print a new one out of Ninjaflex, or build his own desoldering station. Or maybe he’ll turn to the fire and tweezers method.

While working on a project recently, I required a capacitor of around 1000 μF and went rummaging through my collection of parts. No luck there. At that point I’d usually go through my collection of junk electronics and computer motherboards, but I had recently gone through and tossed the stuff that had been laying around for as long as I could remember. No matter, I thought. I’ll just head over to RadioShack and…
Now, I have been accused of many things over the years, but “deep” is certainly not one of them. Yet, at this moment I had what could only be described as an existential crisis. There is no RadioShack, not in my state at least. I don’t live in an area that’s blessed with a maker “scene”, so no independent shop or even a hackerspace within reasonable driving distance of me either. I could order it online of course, but everyone’s trying to sell them in bulk and shipping will take a few days at least. A few days? Who knows where my interests will be in a few days. How can I get anything done under these conditions?
Desperate times call for desperate measures, so I got in the car and took a ride to the only place I knew where I could by electronic components for cheap: Goodwill. Continue reading “My Kingdom for a Capacitor”
If you are an electronics enthusiast who has a tendency to hoard junk because it Might Be Useful Someday, you may well have a significant experience when it comes to desoldering. Why order that component, when you’ve got one on this old board?
So we’ve become experts in removing old components from dead PCBs, so when it comes to desoldering techniques you might think we’ve seen it all, there’s nothing new to learn. Then along comes [fede.tft], with a tip of a desoldering tool that’s new to us. The video below the break from [MSylvain59] demonstrates the needles in action, what do you think? Have any of you used a desoldering needle?
This is a set of tools you might use to desolder a through-hole component with a wire-end poking out beneath the board. The idea is that as stainless steel needles the solder won’t adhere to them, so you can select the appropriate size and use it to push out the lead from below.
We remain to be convinced, as it seems to be a slightly more fiddly way to do what we’ve used a small screwdriver for to lever from above the board for years, but it’s always worth talking about a tool that could be a useful new weapon in our armoury.

If you know where to go on the Internet, you can pick up an FTDI USB to Serial adapter for one dollar and sixty-seven cents, with free shipping worldwide. The chip on this board is an FTDI FT232RL, and costs about two dollars in quantity. This means the chips on the cheap adapters are counterfeit. While you can buy a USB to serial adapter with a legitimate chip, [Syonyk] found a cheaper solution: buy the counterfeit adapters, a few genuine chips, and rework the PCB. It’s brilliant, and an excellent display of desoldering prowess.
Why is [Syonyk] replacing non-genuine chips with the real FTDI? The best reason is FTDIgate Mk. 1, where the official FTDI driver for Windows detected non-genuine chips and set the USB PID to zero. This bricked a whole bunch of devices, and was generally regarded as a bad move. FTDIgate Mk. 2 was a variation on a theme where the FTDI driver would inject garbage data into a circuit if a non-genuine part was found. This could also brick devices. Notwithstanding driver issues, the best reason for swapping out fake chips for real ones is the performance at higher bit rates; [Syonyk] is doing work at 3 Mbps, and the fake chips just don’t work that fast.
To replace the counterfeit chip, [Syonyk] covered the pins in a nice big glob of solder, carefully heated both sides of the chip, and slid the offending chip off when everything was molten. A bit of solder braid, and the board was ready for the genuine chip.
With the new chip, the cheap USB to serial adapter board works perfectly, although anyone attempting to duplicate these efforts might want to look into replacing the USB mini port with a USB micro port.
