Hi @everyone, on today's OH Meetup we're going to be discussing "How to Get a Customer"! We'll touch on:

Identifying market need and value
- Understanding your target market and customer
Understanding what you are selling
- Spec'ing out your product or service
- Staying on track
Finding and approaching target clients
- Handling special requests (staying on track, part 2)
Getting paid (contracts, etc.)
Open discussion
- What's your big idea and where are you experiencing painpoints in this process?

We've been going down the technology business track for a while so after this session we'll be getting back into nuts and bolts for a bit. If you've got that entrepreneurial spirit, we want to hear from you and about what you're working on

Join the Meetup: https://app.livestorm.co/devheads-community/devheads-weekly-office-hours-1/live#/.

Yyoucef_ali In Zynq SoC what is The fastest way to stream data from PL to PS ?

Navadeep•3/8/24, 3:10 PM

I read 'The ideal PS/PL relation is 650 MHz/150 MHz = 4.33'. So it should in that rate. The AXI Interconnect communicates between PL and PS and nothing else should be a showstopper.

Or you can use ARDUINO IOT Cloud, it gives you 2 sensors for free, and you can unlock more options for fair price

aymen ammari•3/8/24, 6:36 PM

And remotexy also but not so efficient like blink and arduino cloud, the pro version costs 8€ only and it's easy to maintain

aymen ammari•3/8/24, 7:17 PM

Hiii everyone, I'm interested in the capabilities of my electrochemical gas sensor MQ2 . Could you elaborate on the types of gases it can detect and maybe delve into how it discriminates between different gases?

Before this day ends
On the occasion of International Women's Day, get to know the first female programmer in history
On December 10, 1815, the first female programmer in history, named Ada Lovelace, was born.
She is a British writer and mathematician. She lived between 1815 and 1852. Ada lived a somewhat difficult childhood due to illness and family problems. Her father died when she was nine years old. She was interested in mathematics and science, and at the age of adolescence, this is what led her to a relationship with... He worked with the scientist Charles Babbage.
She is mainly known for her work on the Analytical Engine, which was the first computer in history, designed by Charles Babbage. Ada Lovelace was the first to realize that the machine had applications beyond simple arithmetic, and published the first algorithm that this machine could perform, so it is sometimes considered The first to know the full capabilities of the “calculator” and the first computer programmer.

Budweiser•3/8/24, 7:53 PM

is this about suggestion for a video tutorial, or about my own projects?

Budweiser•3/8/24, 7:59 PM

One thing I'd think is really cool..
So, Starlink registered space to earth (downlink) frequency range is e.g. 10.7 to 12.7 GHz (also some more)
A research institute in Germany managed to create a passive radar using starlink as the source, it is pretty great as it is available everywhere on earth, you can discover objects you normally can't by shadowing, so you don't have the normal issues with artificially reduced radar cross sections when you use the shadowing, and it's high bandwidth, which is very favorable for radar pulses.
Would be pretty cool to do passive radar SDR with the appropriate frontend

I—for one—was referring to a video tutorial

@Joseph Ogbonna @Petr Dvořák I think the idea here is to have a PCB design tutorial in KiCad or similar that addresses "the RF critical path from the PHY-Chip to a PCB antenna". That's just one design req of this theoretical demo project/system (unless we're building John's Starlink SDR, haha)

Petr Dvořák•3/9/24, 6:12 AM

Such an RF path can be designed easily. The issue is such an RF path must be evaluated with expensive RF instruments later. The task is simple. You need two impedance-matching networks (one at the transceiver output and the second at the antenna feeder) and a transmission line. For both networks, there are recommended designs by the transceiver manufacturers. For the transmission line, there are calculators on the Internet. To design such an RF path is not rocket science. Making it correctly involves prototype evaluation and measurement. The tutorial would be a longer format than a 3-5 minute demo.

Nice, one of the things we were just talking about is the RTOS SDK. Are you working with an RTOS?

WRT LoRa FUOTA, @BenCos18 have you done any updates on your LoRa network?
