Hey guys, quick question please. I have been to every site listed on the pslab.io website looking for a place to order the Pocket Science Lab Board. Every one says it is out of stock. Any idea when it will come available again? This stuff is right up my alley and I'm so glad to have stumbled across it on Github. Great work!

Hi @anurag629 - there is an introduction to PSLab here in the docs: https://docs.pslab.io/introduction.html
TIL: https://pid.codes they give free USB VIDs/PIDs to open source projects from a pool they managed to allocate
I have a RISC-V dev board here based on the CH32V307, capable of USB, where I can just set the VID/PID as I like.
(vendor/product ID)
(vendor/product ID)
ended up there looking at github.com/hydrausb3
I made a pull request. There are too many modifications, details are in the log. PCB modifications other than the final version are not included in the commits. I removed them due to the size expansion of the repository.

@vgfsrhkbgd:matrix.org @bessman Do you want to add the points you found in the prototype in this PR or in a separate issue? CloudyPadmal/pslab-hardware#8
and does some stuff like turn on and off
Well, every function and class have documentation with a simple usage example. Beyond that, there are no organized examples.
Is there more sample code for humidity (HL 83 rain sensor)
Turning on an LED could be done using the current source pin (PC, I think is the label). But it's not powerful enough to drive a bright LED.
I think the HL83 is one of the old sensors which hasn't been updated for the new API. Really old parts of the codebase is often undocumented.
I'll see if I have time to put something together later tonight.
small individual examples for people to try
no need for a big generic thing
MQ-2 Gas Sensor Smoke Sensor Air Quality Module would also be interesting
And pressure sensor like this experiment here https://docs.google.com/document/d/1w9e40NUY457jBPoiFhbM8322EL7UKi0zzWWQMIBnn3Y/edit#
Thanks for you feedback! We are on the train to Weimar. Talk later

I spent sometime going through the code myself but it takes me some time to figure out each example.
The instructions say to connect an LED in parallel with a force-sensing resistor via CH1, but the android app instructions then go on to manipulate PV3 (which isn't connected to anything). I don't see how that could work.
I unfortunately don't have a FSR to test with.
Looks like the android parts of experiments 3 & 4 had gotten mixed up. I've fixed it.
I've added python instructions to the following documents:

These documents could be turned into Jupyter notebooks for a streamlined python experience... if time allows.
I'd like some more details on the multivibrator experiment. It's not clear to me how the pslab should be connected to the experiment circuit.
I honestly don't know much about the multivibrator experiment as it something that it was done there before and I don't really understand.
Is the workshop ongoing? I'm trying to join remotely, but there's no one in the jitsi room.
Hello, I'm an electronics undergrad looking to work on interesting stuff. I had come across neurolab back in November, but it turned out to be dead, including the gitter channel. I now again came across pslab, after someone mentioned fossasia internship. Is it possible to initiate an internship considering I am new? And how do I get started? I suppose I may need the kit, but its out-of-stock.
Hi Siddh, and welcome to the PSLab Gitter channel! While @mariobehling is the person to talk to regarding internships, I can say that in the past internship candidates have been required to have a history of contributions to FOSSASIA projects.
The PSLab, as you have noticed, is currently out of stock pretty much everywhere. This is because we're getting ready to release a new version of the hardware, which is currently in prototype stage. We have discussed doing a limited production run sometime soon to make the prototype available to interested parties. Once that happens, it will be announced in relevant channels, so stay tuned!
