CNX Software ☛ High-end 8-channel oscilloscope features 12-core AMD EPYC CPU, 96GB RAM, 15.6-inch display, and more
Tektronix has launched the 7 Series DPO (Digital Phosphor Oscilloscope), and the company claims the DPO718AX model is the world’s first 8-channel performance oscilloscope with up to 25 GHz analog bandwidth per channel (and 125 GS/s sampling). The new family is designed for high-speed serial compliance testing, wideband RF analysis, and high-energy physics research. Powered by a 12-core AMD EPYC Embedded 3351 processor paired with 96 GB RAM, 1.6 TB storage, an NVIDIA T1000 GPU, and a 15.6-inch touchscreen display, the oscilloscope looks like a high-end PC running GNU/Linux (or backdoored Windows 10 LTSC).

Hackaday ☛ Teaching A Robot Hand To Walk
Although it wasn’t apparently designed with this in mind, it seems particularly fortuitous that this walking robotic hand was released in time for Halloween. Designed by researchers from ETH Zurich, the slightly unsettling disembodied hand can use its fingers as legs to traverse terrain, push small objects around, and operate a keyboard.

Hackaday ☛ A Hotspot Becomes A Handheld
The build walks through a few case mods and a PCB mod on the modem, getting the keyboard to fit, and making a custom power board. Perhaps the software setup is the most interesting part, because this isn’t a simple case of installing a distro. Instead, there’s quite a bit of hackery to get the display working.

Hackaday ☛ Laser Your Way Into Debug Mode On The RP2350
Okay — movie clichés aside, the laser was in fact very carefully focused on target before they turned it on. That target was the register that enables the 2350’s debug features. Said register was located by decapsulating the chip and examining the die with photon-emission electron microscopy; the actual attack was carried out on a chip that had been decapped on the back side, with IR shining through the silicon wafer. There was probably more than a little trial-and-error to figure out exactly where on the die adjacent to the register to zap with the laser to flip those bits. But flip they did, restoring the debugger’s access to the secure execution zone. Then, after resetting the chip, [Ledger]’s team read the 128-bit secret the Pi Foundation hid in memory as part of the 2350 hacking challenge.

Hackaday ☛ Teardown And Repair Of A Insoma Water Timer
Water timers are nifty devices that can water the lawn at set times or keep that vegetable garden from turning into a dustbowl. When [electronupdate] timer refused to output water on any of its three outlets, he did the right thing. Instead of angrily checking the warranty on the sodding thing, he tore it apart to attempt a repair.
