Yes, you mean battery power/low powered Chips

SSwapn Hii

techielew•2/15/24, 9:50 PM

What's up Swapn! Welcome! Can you tell us a little about your background? Why do you want to make a Tesla coil anyway?

Ppallavaggarwal Hardware or firmware?

techielew•2/15/24, 9:52 PM

Relative question, but I know that @controls4all is working on building automation solutions based on BeagleBoard, @JKridner actually makes BeagleBoard, @gy4nt works at Balena and probably has a bunch of connections building low power devices. Why do you ask?

techielew•2/15/24, 10:06 PM

Hey @Software Integration friends, there's a new DevHeads Demo out on buildroot/menuconfig with our @abhishek awasthi. If you've got 5 minutes, check out the discussion thread (📦-middleware-and-osDevHeads Demos: Navigating the Buildroot Menuconfig) or the YouTube vid: https://youtu.be/z3CS7xuMwFs !

DevHeads Demos: Navigating the Buildroot Menuconfig

If you want a specialized Linux implementation, you want buildroot. It allows devs to trim the fat off the normally-bloated Linux operating system by selecting only the packages they need for a particular application — and thereby reducing footprint and boot time.

If you're new to buildroot, one of the first things you'll encounter is the menuc...

Some updates about the Tiny Scarab board:

- The first prototype arrived, was tested and it works.

- The enclosure design is ready, including the "graphical overlay membrane". I'll get them produced asap in China.

What's your cost?

kristof-at-embeetle•2/16/24, 12:05 AM

The factories are still closed because of Chinese new year. I will find out more reliable prices next week.

Hey, just an idea(if not already implemented), do create a channel for sharing events, workshops, conferences so one can share and maybe participate

techielew•2/16/24, 1:36 AM

That's a good idea. I had been thinking that such things would just go in the #dev-heads-feed or similar. Maybe the Events tab, though that might get confusing.

Perhaps we create a "resources" channel... What says the group?

techielew•2/16/24, 1:39 AM

Hey guys :waving_hand:
A little over 12 hours 'til our next meetup and we have a topic this week I think everyone will enjoy: "Who is Your Engineering Hero? Identifying, Engaging & Maximizing Technology Mentors"

We hope you'll join us and share. Here's the meeting thread in case you want to drop some thoughts in before, after, or if you can't make it: https://discord.com/channels/1130679493799977062/1207862407028932659

See you tomorrow (or today for some of you)!

JJoseph Ogbonna Yes, you mean battery power/low powered Chips

pallavaggarwal•2/16/24, 2:07 AM

Yes

Ppallavaggarwal Yes

Joseph OgbonnaOP•2/16/24, 2:09 AM

I am

pallavaggarwal•2/16/24, 2:10 AM

Great. Do you mind sharing details?

Saßì•2/16/24, 2:24 AM

@Amin Sujan Welcome,! We're happy to have you as a DevHead. Feel free to let us know what you're working on now and a bit about your technical background.

Ppallavaggarwal Anyone who is building something low power?

onky•2/16/24, 5:43 AM

I am working on one project.

Ppallavaggarwal Great. Do you mind sharing details?

just saw the video

pallavaggarwal•2/16/24, 10:31 AM

did u end up making the finished version?

Ppallavaggarwal did u end up making the finished version?

Umesh Lokhande•2/16/24, 10:39 AM

you mean on actual PCB? I have to find time this summer to convert this working circuit from the Protoboard to the real PCB with casing. but I enjoyed this weekend project

pallavaggarwal•2/16/24, 10:42 AM

yes, actual PCB version

pallavaggarwal•2/16/24, 10:43 AM

it would be great make that func project with latest CH32V003

Ppallavaggarwal it would be great make that func project with latest CH32V003 🙂

Umesh Lokhande•2/16/24, 10:50 AM

Sure, it can be done with CH32V003. All you need is plenty of GPIO Pins for buttons and I2C Pins for OLED Display that's all. Firmware is also very simple. I'll drop the circuit & code later today in case you wish to review. I skipped some capacitors in my case to avoid hand solder.

pallavaggarwal•2/16/24, 10:53 AM

Yeah sure. I like you being lazy and leaving poor caps home

Hey guys (especially @MCU, MPU & Kits devs), we just launched a new #polls to see what MCU architecture everyone is designing on (or would prefer to be designing on). Check it out: https://discord.com/channels/1130679493799977062/1199293807737450538/1208322777757519952

Oonky Missing MSP430 😅

techielew•2/17/24, 8:07 AM

If I added it would you vote for it lol?

onky•2/17/24, 8:08 AM

Yes, I am working on one. Low power device.

onky•2/17/24, 8:09 AM

STM has killed most of the competition. Firmware libs from TI is painful compared to ST

Oonky Yes, I am working on one. Low power device.

techielew•2/17/24, 8:11 AM

* First, let @pallavaggarwal know what you're working on. He was curious about low-power device designs in server.

* Second, I just added a comment on the poll to reply with any device/architecture that's missing. We should track this over time.

* Yes. Everything but ESP and AVR and RP2040 (curious if anyone will comment that last one out :))

techielew•2/17/24, 8:15 AM

I lied. I actually want to know what your low-power device design is too, @onky lol. And why is it on MSP430?

onky•2/17/24, 8:19 AM

I am working on loop powered instrument, max current consumption for the whole circuit must be less than 4mA. The customer is old school has trust in MSP430 and wants me to use the same.
