It is an offline moving map with very fancy marker etc support. Seems a good choice for a hiking app?

To make a compliant ethernet signal from this you would need at least some sort of line driver/receiver as well.

Just put normal test pads next to the tag connect, a bit more spaced out. A bed of nails in the production line connects to that, the tag connect can be used for bench development.…

We tried this long ago at a university, the cards we had were entirely invisible to the x-ray. I think the 'x-ray' table in the article works with IR cameras and illuminators under…

Laser decapping will destroy the die, except if you have a rare package that does not mix glass in the epoxy. You could still compare the internal structure of the package and bond…

A lot of low population density cellular backhaul runs over satellite. Two factor SMS or voice can be directly intercepted, assuming encryption is not used.

A solar panel is like a normal silicon diode. The voltage over the cell goes up drastically with lower temperatures. In cold climates crowbars are usually added.

This architecture is good for data path applications, but not really for control flow (eg, think how expensive a context switch would be)

Usually yes, but it is not an EU-wide system. Contact your spectrum regulator and ask for what options are available for private 5G[1]. You can likely get a bit of spectrum in the …

In the Netherlands you can run private 4G in the 1.8GHz GSM guard band. For indoor use with 200mW or less no license is required.

No, unless the Android is already rooted, it is not possible to send vendor HCI commands.

A very far stretch: You have a ESP32 based Bluetooth dongle, that exposes its HCI interface to the host. You have already gained access to the host and can now load code to the don…

The people in these talks go quite a bit further than just BLE packet TX/RX (which you can do with the documentation on most chips). In theory this work allows implementing a total…

The interface to configure an eSIM is standardized, there is no need to use the proprietary app. You might even be able to configure it with the software included with the phone OS…

There are many products like this, eg: https://shop.sysmocom.de/sysmoEUICC1-eUICC-for-consumer-eSIM... https://esim.me/

I worked on this long ago, the main problem with the poor sound quality is that the self-mixing process is non-linear, a good approximation is squaring the output signal. To improv…

With a rate of 1.5%, paying the loan off might not be a smart move, as long as you don't mind not being fully debt free.

How does the mercury get into the water?

That functionality is absolutely non-trivial. There are a few WiFi cores (digital and RF) you can license but they are expensive and the analog part uses a lot of die area. If you …

It's very unlikely IMHO. Both the RISC-V and the M33 are very tiny in die area, compared to for example the 512kB RAM, or even compared to a few bond-pads. Making a single core wit…

If you can tolerate some level of false positives you can turn the CRL into a bloom filter and save quite a bit of storage.

Marvell 88E6393X works in 'dumb/externally managed' mode without firmware. You can use it with Linux switchdev like the one in this article.

While you could make an OpenFlow client that uses this switch chip as the data-plane, it might not be the best as most of the features you would use OpenFlow for would not be able …

Not really, if you use IPv4 BROADCAST the traffic will go to all machines. If you use multicast and IGMP support is turned on in the switch the data will only be forwarded to recei…

This device is not really suited, it is a high speed USB3.0 peripheral. You might be able to use it with the right software, but then you are just using the CPU in it.
