@Event Pings We're about to dive into how and why you pick an Arm MCU (and vendor). Hope to see all you @MCU, MPU & Firmware devs in 10 minutes!

jjbitnic👀•5/11/24, 2:57 PM

I think they are 90% the same, but the 10% difference is important. In this 10% there are things like: sensing if battery is depleted and trying to 'jump start' with trickle current, knowing when battery is charged and stopping the cyle, keeping the charging current constant, etc. The battery charger is mostly a constant current power supply. The battery chemistry is also important when determining the charging cyle.

Marvee Amasi•5/11/24, 2:58 PM

Lifi, huh? Well, I think it's an enlightening idea! Using light signals to transmit data is a brilliant concept, and I'm excited to see where your project shines.
As for experience with LiFi, I've dabbled in it a bit, but I'm no expert. However, I've heard it's for of faster and more secure data transmission . Please do share your project when it's ready

anybody around here involved with reed-switch manufacturing/testing/selection? Niche subject... I'm creating a tester for reed switch parameters since about a year as my side job, and it's been fascinating to see that reed switches are everywhere yet I've never met anybody working with them/distributing them besides the friends I am working with.

Camila_99$$•5/11/24, 6:44 PM

wafa_ath•5/11/24, 8:31 PM

I used Claude ai and that was it answer
Based on the image, these appear to be surface mount technology (SMT) diodes marked with "MURS" and "HW18C". These types of compact diodes are commonly used on printed circuit boards for various purposes like rectification, protection circuits, signal clamping or switching.

The "MURS" marking likely refers to a MURS-series SMT rectifier diode, while "HW18C" could be a model number for switching or protection diodes from a specific manufacturer.

Without more context about the circuit they are used in, it's difficult to definitively state their exact function. However, seeing multiple physically small diode components marked this way strongly suggests these are indeed surface-mount diodes integrated into the design of this printed circuit board assembly.

barafael•5/11/24, 10:08 PM

as far as I'm concerned, we care about Form-A (normally open), Form-B (normally-closed), Form-C (Change-over), and Form-E (latching) switches. All of which require similar measurement approaches. Form-E being the snowflake of course

wafa_ath•5/12/24, 2:27 PM

the diagonal values (representing correct classifications) are relatively low compared to the off-diagonal values (misclassifications). This suggests that the model struggles to accurately classify instances belonging to these classes.
