Ikea JANSJÖ LED Lamps - and/or alternatives (?)

by linux_dan

There are multiple Things out there for R-Pi's that use an Ikea JANSJÖ LED lamp

The desk lamps used to cost $13 at Ikea -
https://web.archive.org/web/20180818172231mp_/https://www.ikea.com/us/en/catalog/products/00385941/
Only $10 for white

The clamp version was $12 -
https://web.archive.org/web/20180210085324mp_/http://www.ikea.com/us/en/catalog/products/90386328/
$10 for white or black

The gripe is that they are no longer available from Ikea, and other online retailers charge double (and more)
$30 +/- $3 -- https://www.amazon.com/Ikea-Jansjo-Flexible-Desk-Light/dp/B0071IFNRO
$25 +/- $3 -- https://www.amazon.com/IKEA-JANSJÖ-Clamp-spotlight-white/dp/9178917174

All that is left are the JANSJÖ LED USB lamps for $6 ( priced at $5 in the same archive.org 2018 catalog )
These only throw 10 lumens vs 88 lumens from the other two

Also, I found out by printing out a Jansjo thing that the USB version is considerably SMALLER than the plug-in versions.

I am not going to waste time and energy asking Ikea to bring them back. Retailers never listen to the customers.

The apparent replacement seems to be NÄVLINGE
https://www.ikea.com/us/en/search/products/?q=NÄVLINGE
Desk lamp for $17
Spring Clamp for $15
Bolt Clamp for $18

I just found a nearby eBay-er that had a clamp JANSJÖ for $22/free shipping.
I bought it so I can compare it to a NÄVLINGE and because it is one of the lowest prices for a plug-in JANSJÖ I have seen recently.

I will post more details as I get them.
Feel free to contribute to the discussion.

RFID trigger servo

by zackpollard_04

I'm working on a RFID door lock. I have the reader set up on my pi, I just need it to trigger a servo motor so it will move the mechanism. I'm closer to the novice side of coding, and I'm a "learn as I go" type. Could anyone point me in the direction as to how to code this to happen? Thanks

Need Help With No Audio From 3.5mm Jack

by rebeltaz

I have asked this question over on the Raspberry Pi forums as well as the Raspberry Pi reddit, with no one offering me any help whatsoever. Thought I'd give this group a shot...

I have a Kano computer kit utilizing a Raspberry Pi 3b. I put Raspbian Buster on an SD card and setup everything up. No matter what I do, I cannot get audio output on the 3.5mm jack with one exception. I have tried forcing Analog Audio using raspi-config , right-clicking on the volume control and through amixer. Audio out through the HDMI interface works fine. I can get audio output through the 3.5mm jack if I force omxplayer using "-o local" but no other program will use the audio jack including VLC or system sounds and the volume control has no effect when I run it that way - even if I right-click and switch to HDMI and back. I have read that PulseAudio might be an issue, and I did try to uninstall that with no difference, but I need that installed anyway for the program I need to run - SilverJuke. I have also noticed that when I run raspi-config, the audio setting doesn't seem to be sticking - i.e. it always defaults to the default setting each time I enter that menu, whereas the other settings seem to stay where I put them. I am out of ideas if anyone could offer some advice/help....

Bee colony pre-swarm indicator

by ljbrumfield

Ok.... basically I want to use a Rasbpberry Pi to monitor the sound inside of a bee hive and listen for

"a sort of warbling noise that varied between the notes A and C sharp; that's 225 - 285 Hz in terms of frequency. "

and then trigger an alarm. I'm already using the Pi as a weight scale/bee counter/weather station so its already out there... this would just be an added feature. I've been following this other thread

https://www.thingiverse.com/groups/raspberry-pi564/forums/general/topic:40612#comment-2772023

and I see people mention Audacity so I went to their website & saw downloads for ubuntu & linux mint, but they say the Pi is unsupported. What build will work on the Pi? Anyone have an idea how to set up Audacity to do what I'm looking for? An insight is appreciated.
