Hi all, How to select Half bridge driver
Hi all, How to select Half bridge driver
T@Joseph Ogbonna @ShreeshaN @Petr Dvořák @pallavaggarwal may have some advice but this is also a great question for @Navadeep during OH later today—especially with respect to how you can effectively source whatever you select: general-dev-chat
TAlso helpful if you can provide some context around the application/use case/system design
MWe want 24V 7A BDC control circuit
PEach renowned manufacturer provides engineers with application notes, reference designs and design guides. I believe the best start is to study available literature before.
WHi guys. Anyone here could help to identify this part.. it's part of DSP preamp board...
LThe one and only @techielew leading the panel conversation during the IoT Stars meeting. It was great meeting you in person!
JAwesome 
NBig shot Brandon! This is awesome @techielew

Hello from Nuremberg for the first day of #EW24. The fire-side chat is heating up.
We're here with @iotstars and Distinguished Arm Ambassador, @gy4nt, discussing how to ensure a thriving ecosystem for edge AI.
4/9/24, 7:45 PM
ALooks exciting
SHi @MCU, MPU & Firmware and @PCB & Analog folks. Today at 1500 GMT, @Navadeep will be leading this week's Office Hours session on Component Inventory, Sourcing & Planning! If you're learning how to navigate component evaluation and lifecycles, this is a great place to start.

CWow! Brandon ! We are so proud of you 
@techielew
@techielewCHello everyone! I have a question 
CI would like to send values from an Arduino to another one (one value every 10 minutes). I have a distance of 80-100m outdoors with trees between the Arduinos. The transmitter should consume as little power as possible because it will be on battery, while the receiver will be on mains power.
What solution do you suggest? I don’t know the maximum distance (WiFi, radio, Bluetooth, IR…).
Thanks

Thanks
JYou can use a simple Lora Device if you are not sure of the distance. It acts as a radio transmitter and covers a large area
Whi camila , recommend using LoRa (Long Range) technology, for long-range, low-power wireless communication , you'll need a LoRa transceiver module compatible with Arduino, such as the RFM95W or SX1276/77/78/79 module
IAnother option is Bluetooth with Coded PHY support. This extends the range of bluetooth and is likely the lowest cost and power. LoRa is a good option as well, but your receiver has to function as a gateway. LoRa will have the best range, but BT coded PHY should meet or exceed your range needs as well. As always with wireless range, I would do some field testing with existing product or dev kits before finalizing your design. Also, antenna design/performance is always a large factor with any wireless design.
T@PCB & Analog and @MCU, MPU & Firmware, should be another hot one from @Navadeep!
NStarting in just about 2 mins. See ya'll there!
COk, thank you! I got it!
CYeah thanks Wafa actually I was wondering about the option of nrf24l01 + pa + lna? Does it consume more power
COkk thank you Mike I’m curious, 
have you encountered any specific challenges or drawbacks when compared to LoRa? I’m always interested in learning from others.

AHi everyone, How do you make sure all parts of your my drone get enough power without making it too heavy or using up too much battery too quickly?
AThis server is amazing
MHello there!
My colleague @Jens Hagemeyer invited me here (indirect pointer to @techielew after our meeting at the embedded world conference).
About me: Electrical engineer, research assistant at Bielefeld University, Germany and co-founder of the startup paraXent. My main expertise is FPGA architecture design (VHDL, HLS), FPGA and embedded Linux design flows.
Involved in PICMG (COM-HPC) and SGET standardization committees.
Interests: heterogeneous computing architectures. New, efficient FPGA programming methodologies.
Build most of my home automation hardware myself using Arduinos, CAN Bus, ESPHome & Home Assistant
Looking forward to learn & chat here!

TWelcome, Martin! Glad to have you!
What’s one thing you’re hoping to learn/work on in the near future (related to electronics/embedded design)? And what’s one thing you’d like to see from the community that would keep you coming back?

MGood Questions I guess I will browse it once a week or so and just look for interesting topics. I have planned some open source hardware stuff (small PCBs for home automation) and will post them in here (after pushing it to github)

S@Speed @Dark Welcome to the community! We're eager to learn more about you. Can you introduce yourself and tell us about your professional life?
SNo problem! Cattle rancher from Namibia, EE degree from Pretoria, SW post graduate degree from an Ivy League school in Massachussets, Aerospace to Medical, moved to Texas, Systems Engineer at Flex Medical to Law Enforcement Radar at ACI and writing Firmware for a Neuromodulation implantable device today. All while creating boards and code using less wires in model railroads where today we are using MQTT with ESP01 devices in mqTrains(.com)!
MPlease I need to know how I can efficiently process Kafka event streams, store relevant data in memory, and deliver it to a REST API without persisting events. I am new to using Apache Kafka.
@Middleware & OS
@Middleware & OS
JTo efficiently process Kafka event streams without saving them, first, understand the data flow using Kafka's consumer groups. Then, use in-memory data structures to store relevant information temporarily. Finally, design a REST API interface to deliver the processed data to callers. Familiarize yourself with Kafka's consumer APIs and explore libraries for in-memory data handling.
Whello everyone. what is the best service to send periodic HTTP requests (pings) to your application's URL every 10-15 minutes
AThere are several services you could use for that purpose. Some popular ones include UptimeRobot, Pingdom, and StatusCake.
Wwhich one do u recommend ?
AUptimeRobot is the simplest one of them.. Soo yeah
Wokay thank you aymen
Thiii
Ti'm not exactly developing anything currently but i would like to learn more about embedded devices and such
AYeah ypu can here ask for guidance and help, ypu are very welcome
TInteresting: https://uptimerobot.com/website-monitoring/
But can get expensive pretty fast. What was your application, aymen?
