[Sverd Industries] have created a pretty cool bench power supply integrating soldering helping hands into the build. This helps free up some much-needed bench space along with adding that wow factor and having something that looks quite unique.
The build is made from a custom 3D printed enclosure (Thingiverse files here), however if you have no access to a 3D printer you could always just re-purpose or roll your own instrument enclosure. Once the enclosure is taken care of, they go on to install the electronics. These are pretty basic, using a laptop PSU with its output attached to the input of a boost/buck module. They did have to change the potentiometers from those small PCB mounted pots to full size ones of the same value though. From there they attach 4mm banana sockets to the output along with a cheap voltmeter/ammeter LCD module. Another buck converter is attached to the laptop PSU’s output to provide 5V for a USB socket, along with a power switch for the whole system.
Where this project really shines though is the integrated helping hands. These are made from CNC cooling tubes with alligator clips super glued to the end, then heat shrink tubing is placed over the jaws to stop any accidental short circuiting while using them.
This isn’t a life changing hack but it is quite a clever idea if space is a hot commodity where you do your tinkering, plus a DIY bench power supply is almost a right of passage for the budding hacker.
Counterfeit parts are becoming increasingly hard to tell the difference from the real deal, the technology used by the counterfeiters has come on leaps and bounds, so even the experts struggle to tell the real product from a good fake. Mere fake branding isn’t the biggest problem with a counterfeit though, as ieee.com reports, counterfeit parts could contain malware or be downright dangerous.
Way back in 2014 the FBI charged [Marc Heera] with selling clones of the Hondata S300, a plugin engine module for Honda cars that reads sensors, and depending on their values can change idle speed, air-fuel mixture and a plethora of other car/engine related settings. What, might you ask, is the problem, except they are obviously not genuine parts? According to Honda they had a number of issues such as random limits on engine rpm and occasionally failure to start. While the fake Hondata S300 parts where just poor clones that looked the part, anything connected to an engine control unit brings up huge safety concerns and researchers have shown that through ECU access, they could hijack a car’s steering and brakes.
It’s not just car parts being cloned, remember the fake USB-to-serial chips of FTDI-Gate? Entire routers are also being cloned, which doesn’t sound too bad until you realise that the cloners could configure your internet traffic to be redirected through their network for snooping. In 2010 Saudi citizen [Ehab Ashoor] was convicted of buying cloned Cisco Systems gigabit interface converters with the intention of selling them to the U.S Dept of Defense. While nothing sinister was afoot in [Ashoor]’s case other than greed, these routers were to be deployed in Iraq for use by the Marine Corps networks. They were then to be used for security, transmitting troop movements and relaying intelligence from field operations back to HQ.
So who are the cloners and why are they doing it? It is speculated that some of them may be state funded, as there are a lot of countries who do not trust American silicon. Circuits are reverse engineered and find their way to the international market. Then just like the FTDI-Gate case, cloners want to make profits from others intellectual property. This also brings up another question, if there is a mistrust of American silicon, nearly everything is made in China these days so why should we trust anything from there? Even analog circuits can be made to spy on you, as you can see from the piece we recently featured on compromising a processor using an analog charge pump. If you want to defend yourself from such attacks, perhaps look at previous Hackaday Prize finalist, ChipWhisperer.
[Films By Kris Hardware] has started quite an interesting YouTube series on hacking and owning a PogoPlug Mobile v4. While this has been done many times in the past, he gives a great step by step tutorial. The series so far is quite impressive, going into great detail on how to gain root access to the device through serial a serial connection.
PogoPlugs are remote-access devices sporting ARM processor running at 800 MHz, which is supported by the Linux Kernel. The version in question (PogoPlug Mobile v4) have been re-purposed in the past for things like an inexpensive PBX, an OpenWrt router and even a squeezebox replacement. Even if you don’t have a PogoPlug, this could be a great introduction to hacking any Linux-based consumer device.
So far, we’re at part three of what will be an eight-part series, so there’s going to be more to learn if you follow along. His videos have already covered how to connect via a serial port to the device, how to send commands, set the device up, and stop it calling home. This will enable the budding hacker to make the PogoPlug do their bidding. In this age of the cheap single-board Linux computer, hacking this type of device may be going out of style, but the skills you learn here probably won’t any time soon.
Remember all the talk about modular smart phones? They sounded amazing! instead of upgrading your phone you would just upgrade the parts a bit like a computer but more simplistic. Well it seems modular phones are dead (video, embedded below) even after a lot of major phone manufacturers were jumping on the bandwagon. Even Google got on-board with Google Ara which was subsequently cancelled. LG released the G5 but it didn’t fare too well. The Moto Z from Motorola seemed to suffer from the same lack of interest. The buzz was there when the concept of these modular phones was announced, and people were genuinely exited about the possibilities. What went wrong?
For a start people expect their phones to have everything on board already, whether it be cameras, GPS, WiFi, high-capacity batteries or high-resolution screens. Consumers expect these things to come as standard. Why would they go out and buy a module when other phones on the market already have these things?
Sure you could get some weird and wonderful modules like extra loud speakers or perhaps a projector, but the demand for these items was small. And because these extras are already available as separate accessories not locked down to one device, it was a non starter from the beginning.
When we did our user studies. What we found is that most users don’t care about modularizing the core functions. They expect them all to be there, to always work and to be consistent. — Lead engineer Project Ara
The hackability of these phones would have been interesting to say the least, had they come to the mainstream. It just seems the public want thin sleek aluminum phones that they treat more as a status symbol than anything else. Modular phones have to be more bulky to accommodate the power/data rails and magnets for the modules, so they’ll lose out in pocketability. Still, we hope the idea is revisited in the future and not left on the scrap-heap of obsolescence.
Would you buy a modular smart phone? Even if it is bigger or more expensive? Is that really why they failed?
