Finally, a 3D-printed prosthetic finger for partial amputees: it attaches to the remains of the finger and is powered by its movement, no electronics required.
The team aimed for something capable of gripping 25kg and fell quite a bit short, but it still works for lighter things like remote controls.
Then a submersible vehicle designed to sink a #RaspberryPi to the depths in order to snap photos and log them with the time and water temperature for environmental monitoring.
Made cheap-like from acrylic and PVC tubing - but it's not a ROSV, as it has no propulsion. Well, it kinda does: a dumbbell makes it sink, and a rope you hopefully remembered to tie to the frame makes it rise.
Another #OpenHardware microcontroller project next in the PD240W, a USB Power Delivery power supply for motors capable of shoving out 48V at 5A.
Theoretically, its creator admits he's not tried it beyond USB PD 3.0 specs. Oh, and if you're building one you'll need a couple of bodge-resistors to fix a PCB layout whoopsie.
Right, last #Hackster round-up of the week and then it's on to write ten(!) articles for the delayed FOSSiF newsletter.
First up: ToothPaste, an ESP32-based dongle that lets you connect via WebBLE and send keystroke commands over an encrypted link... so it types them out on any USB HID-compatible device. Basically a way to use a password manager on an untrusted machine!

And finally, a 3D-printed remote control designed to be easier to operate with visual impairment - running for years from two AA batteries thanks to an ATtiny84 in sleep mode.

A wooden lockbox with a difference: there's a gyroscope inside, and unless you twist and turn it in exactly the right pattern it simply won't open.
Then Microsoft says it's completed research on a data storage technology which encodes voxels into glass sheets to store terabytes for tens of thousands of years.
...but, at the moment, requires a room-filling femtosecond laser setup and a stupidly high-resolution camera to read the data back, so don't expect it in a laptop any time soon.
And finally, Martijn Braam's PiCam - final name yet to be decided - is a #RaspberryPi 4-powered camera built for low-latency live streaming and featuring a clever dual-output system with overlaid user interface.
Which, and here's the clever bit, keeps working even if the user interface part falls over.

Rather more niche, but will be *extremely* handy for those who need it, is the Antenom NanoFarfield, an add-on designed to provide easy far-field measuring capabilities on a NanoVNA or LiteVNA.
The hardware will be open, the company promises, but it's keeping the software closed-source.

Then another new board from @olimex, currently up for pre-order: the ESP32-P4-PC, which you'll be amazed to hear is built around the Espressif ESP32-P4.
Plenty of features, and as always it's #OpenHardware with a permissive MIT licence.
It's #Hackster round-up time, nice and early today - but only because I'm procrastinating over other things I have to do today...
Anyway, first up is the news that the #AsteroidOS project, which builds alternative operating systems for smartwatches, has hit the 2.0 release milestone - with better performance, new apps, and more watches supported.
And to finish, an under-cabinet radio replacement built using an ultrawide HDMI display and a #RaspberryPi single-board computer.

Next up, a smartwatch with difference: it's a pocketwatch, and it's 3D-printed... in stainless steel.
It'll be getting a silver housing in the next iteration, too. All powered by an Espressif ESP32 inside.

Then the slightly-unfortunately-named "SexyberDeck", which eschews modern approaches like 3D printing and laser cutting for a truly cyberpunk build housed in the remains of an Akai MIDI keyboard.

It's #Hackster round-up time, and today we're starting with a *fantastic* project from @slyka: an analog TV transmitter built using almost nothing but an STMicro STM32 microcontroller and a bunch of clever coding.
#Technology #News #Makers #Retro #Displays #Microcontroller #OpenHardware
And last, but only because I lost track of where I was in the list and skipped over it, a work-in-progress project to create an open-source turntable - but one that can be expanded via five modular sockets accepting everything from a robotic record-flipper to a communications interface for vintage computers.
It's early days, but the creator just passed the milestone of first playback on the tone arm!

Another project I've enjoyed seeing come together, next: the LT6502, @PaulaMaddox's homebrew MOS 6502-based BASIC-running laptop in a 3D-printed housing.

Less welcome news from Carrie at @alpenglow, sadly: the business is shutting up shop, with a stock clearance sale now on.
Hopefully not the end of Carrie's excellent projects, though - I've loved seeing those over the years.
Rather late #Hackster round-up to start this week, 'cos my eldest wanted the desktop to play with some friends so I took the opportunity get some stuff done offline.
First up, a device from @bikerglen that turns any MIDI control surface into a fast-boot soundbox for live or streaming shows.
