@CloudyPadmal reinstalled inkscape via ppa, plus some python libraries, now it seems to work, except for edge-cut circles

I was thinking about the two modes the firmware should support. https://github.com/fossasia/pslab-firmware/issues/73#issuecomment-951198375

Hi, I tried to join the install workshop yesterday, but came a bit later, at 4:30pm, though noone was in the BBB... did I get something wrong? I signed up via eventyay and used the link there. Next week I can't make it because we're having the annual Labortage event at our hackerspace https://wiki.das-labor.org/w/Labortage_2021
Mario Behling
@mariobehling
@CyReVolt:matrix.org Such a pity! In the meeting we had decided to switch to Jitsi in order to enable everyone to share their screen. It was in the chat, but we should have also shared it here. Sorry about that. We are doing a repetition of the process next week again.
CyReVolt
@CyReVolt:matrix.org

Yea next week I can't join because it collides with Labortage.
Hope things are smooth for everyone! The easiest way will be on Arch, just yay -S pslab-desktop and it works. The Python lib is pulled in as a dependency automatically with all its requirements.

Hi, after the good workshop last week we are doing a second workshop to share about the desktop installation process of the PSLab app. Please join us this Saturday from 16.00 - 18.00 CET at https://eventyay.com/e/873f2ec3-d433-448a-8b72-e7520694e5c0

It usually happens in the first few months of the year.
Google have to make their official announcements and select orgs, etc. :)

@0904-mansi theres never any guarantees which orgs get selected by Google, but people can always start contributing to open source projects! and pslab have a lot of smart people in case of questions along the way.

@0904-mansi: Someone else here may have a better ideas, but you might want to start by browsing the projects at https://github.com/fossasia and looking to see which interest you. Most will have documentation about how to chat with the project team. For example this project Pocket Science Lab you can ask questions here. But each project will be a little bit different in how they work so you'll want to watch, ask, and learn.

I'm trying to start the development server of this project https://github.com/fossasia/pslab-webapp. I am following the steps as given but it's not starting throwing error [mansim@mansi frontend]$ ember s environment='development'
Required packages are missing, run npm install from this directory to install them.
whereas I have run npm install 3 times again and again it is throwing this error what should I do? Please help
Thank you!!

@0904-mansi This repo is currently inactive as we are focusing on the hardware, Android and desktop app. Please check out the desktop app here https://github.com/fossasia/pslab-desktop
Please join us today at 8.30 IST for an installation workshop https://eventyay.com/e/873f2ec3-d433-448a-8b72-e7520694e5c0

Hello @CloudyPadmal I had a talk with @RafaelLeeImg and he can help us with the hardware further. There are a number of components that are not easily available. These can be substituted with other components but this will require some changes of the hardware layout. Do you have any feedback about this? I think he could make PRs in the harware repo for any changes, right?
Padmal
@CloudyPadmal
Sounds great. I think we can go ahead with that! :+1:

I found a power bank charging management chip, supports 1.5A charging and 2A, 5V boost output, IP5206 or IP5305. The price is arount οΏ₯1 RMB. It can replace LTC4040. The LTC4040 is around $5 USD in China. What do you think? The datasheet is in Chinese. I think the chip is widely sold in power bank around the world but it's only used in Chinese made power banks.
Any comments?
Mario Behling
@mariobehling
@RafaelLeeImg Nice. Do you have a link to the component/manufacturer?
RafaelLeeImg
@RafaelLeeImg
Here's the site of the IC manufacturer.
http://www.injoinic.com/product_detail/id/21.html
It just suddenly came to my mind that we can use power bank IC.

Hi. The USB-to-Serial chip CP2102 I can find, but the price is a little high around $1.7 USD. However I found that PL2303GL is available, the price is half of it. The speed limit is 115200, is the speed enough?
Padmal
@CloudyPadmal
We're running at 1,000,000 baud rate. 115,200 is a bit slow..
RafaelLeeImg
@RafaelLeeImg
OK. Is there any other specific requirement for the USB-UART converter?
Padmal
@CloudyPadmal
Data rate is the key point. Other than that, it's the component count. CP210x doesn't require any crystals etc.
RafaelLeeImg
@RafaelLeeImg
CP2102 QFN24 is out of stock. I bought 1000 pcs of CP2102 with QFN20.

@RafaelLeeImg
I sent the modified PSlab v6 to manufacturer. I changed nearly all power ICs to make the design able to manufacture.
Now the only blocking things are MCP4728 and MCP6S21 are not found.
Mario Behling
@mariobehling
@RafaelLeeImg Thanks! Curious to learn how it is working. We have a quote of another supplier in China as follows:
MCP4728: RMB 86.000
MCP6S21: RMB 10.800
What do you think about this?
RafaelLeeImg
@RafaelLeeImg
MCP6S21: RMB 10.800 is OK. MCP4728 is too expensive, think about this, we can use even several stm32s to replace this DAC, there is no reason to use that.
