Google should come up with a solution to fix the heat and inefficiency issues related to magnetic battery packs. I have a suggestion:
A magnetic powerbank+phone case that go beyond magsafe to bring energy directly from a magnetic battery into the phone via a hybrid approach.
Imagine a battery pack with a few pogo pins embedded around its magsafe ring that could pair with an phone case that has the matching contact pads, along with a wire embedded in the case that goes from the magsafe ring into the phone's usbc port.
Energy from the battery pack could flow directly into the usbc port of the phone, without loose wires, giving both the benefit of a magsafe connection (pocketable, easily removed when not needed, backwards compatible with qi2, works with magnetic accessories like phone grips, car mounts, wallets, etc), along with the benefits of direct contact energy transfer (no loss of energy and much better thermal management). Something like this could handle 25 watts easily, and probably a lot more.

what if there was a battery pack with pogo pins aligned around its magsafe ring that could pair with a phone case that also had the matching contact pads, along with a wire that transferred power directly up into a phone's usbc port, so that, when the magsafe battery pack with pogo pins magnetically attached to the corresponding phone case, it would send power directly into the usbc port of the phone, giving both the benefit of a magsafe connection (pocketable and wireless), along with the benefits of direct contect energy transfer (almost no loss of energy, and improved thermals)
could something like this help address the general wireless charging issue?

hackaday unofficialFlexyPins Might Help With Those Pesky Castellated Modules
[SolderParty] just announced FlexyPins (Twitter, alternative view) - bent springy clips that let you connect modules with castellated pins. With such clips, you can quickly connect and disconnect any castellated module, swapping them without soldering as you're prototyping, testing things out, or pre-flashing modules before assembly. They're reportedly gold-plated, and a pack of ~100 will set you back 6EUR, shipping not included.
Of course, this is basically "fancy pieces of wire", purpose-shaped, gold-plated and, hopefully, made out of material that is springy enough and doesn't snap easily after bending a few times. We've seen this concept used for prototyping before, with random pieces of wire doing a pretty good job of maintaining connectivity, but these clips bring it that much closer to production-grade. It also makes us wonder - just how hard it is to solder 30-40 of them into a circuit? Do they self-align enough with the footprints given, or do you have to hold them with tweezers at a peculiar angle as you solder them? Time will tell, of course.
Don't expect to see them used in regular circuits, as they're quite space-consuming. However, for those of us prototyping and manufacturing, this is one more tool in our arsenal, and we've already seen some fun uses for these. They could also be pretty useful for experimenting with firmware of proprietary castellated modules, letting you reuse the same development board between different modules as you tweak things. And, if you're like us and got a drawer with dead NodeMCU ESP32 boards, having a springy breakout for testing ESP32 modules might come in handy.
You can likely make such pins yourself - we've reviewed this principle before, with a nice 3D-printed jig to match! Flashing and testing castellated modules before soldering them seems to be a popular scenario, and for the aforementioned ESP8266 alone, we've reviewed quite a few testing and flashing jigs - check out this 3D-printable one, or this Wemos-board-turned-pogopin-jig one!
We thank [Chaos] and [adrien] for sharing this with us!

Production PCB And Pogo Pins Produce A Clever Test Jig
[Hans Summers] runs a site qrp-labs.com, selling self-assembly kits mostly for radio gear and GPS applications, and had some production problems with his QCX+ 5W QRP transceiver kit. They were using an assembly house that had some problems with a sub-contractor going under during the pandemic, and the replacement service was somewhat below the expected level of quality, resulting in a significant number of SMT populated boards coming out non-functional. Obviously, not wanting to pass these on to customers as a debug problem, they set to work on an in-house QA test jig, to give them the confidence to ship kits again. The resulting functional test jig, (video, embedded below) takes a fairly interesting approach. Skip the video to 9:00 for the description of the test jig and detailed test descriptions.
By taking an existing known-good PCB, stripping off all the SMT parts, and moving the through hole components to the rear PCB side, pogo pins could be soldered to strategic locations. Building the assembly into a rudimentary enclosure made from sawn-up raw copper clad board, with the pogos facing upwards, and a simple clamp on top, allowed the PCB-under-test (let's call it the UUT from hereon) to be located and clamped in place. This compressed the pogos in order to make a firm electrical contact. A piece of MDF that had been attacked with a dremel did duty as a pressure plate, with cutouts around the SMT component areas to achieve the required uniform board pressure and keeping the force away from the delicate soldered parts. All this means that with an UUT connected via pogo pins to a through-hole only test PCB, the full circuit would be completed, if and only if the UUT was completely functional, and that means defect-free soldering and defect-free components.
Next the firmware was rewritten to do duty as the test controller, which when powered up would step through a sequence of test scenarios and measurements, logging the results to an OLED display and a serial interface. This rig survived 1,000 SMT tests without failing, giving [Hans] the confidence to ship out new kits and providing a database of datalog results as a backup should a customer have an issue during final assembly. All-in-all a smart idea to solve a difficult problem, with nary a custom test jig PCB in sight!
These pages have been graced with many a pogo-based test rig over the years. Here's one to start, and if you've got a handy laser cutter and some scrap wood, making an accurate test rig is no bother either.
Thanks [Paul] for the tip!
SMART Response XE Turned Pocket BASIC Playground
Ever since the SMART Response XE was brought to our attention back in 2018, we've been keeping a close lookout for projects that make use of the Arduino-compatible educational gadget. Admittedly it's taken a bit longer than we'd expected for the community to really start digging into the capabilities of the QWERTY handheld, but occasionally we see an effort like this port of BASIC to the SMART Response XE by [Dan Geiger] that reminds us of why we were so excited by this device to begin with.
This project combines the efforts of SMART Response XE support library by [Larry Bank] with Tiny BASIC Plus, which itself is an update of the Arduino BASIC port by [Michael Field]. The end result is a fun little BASIC handheld that has all the features and capabilities you'd expect, plus several device-specific commands that [Dan] has added such as BATT to check the battery voltage and MSAVE/MLOAD which will save and load BASIC programs to EEPROM.
To install the BASIC interpreter to your own SMART Response XE, [Dan] goes over the process of flashing it to the hardware using an AVR ISP MkII and a few pogo pins soldered to a bit of perboard. There are holes under the battery door of the device that exposes the programming pads on the PCB, so you don't even need to crack open the case. Although if you are willing to crack open the case, you might as well add in a CC1101 transceiver so the handy little device can double as a spectrum analyzer.
