"More than 95 percent of human exposure to industrial #pollutants like #dioxins and #PCBs comes from foods like #meat, including fatty #fish, and #dairy, but the pollutants don’t appear magically..."

My first job out of college was at Teradyne, a company that makes PCB and semiconductor testers. Had a nostalgia jag and looked up pictures of the bonkers PCBs that went into their equipment. (I was writing test automation software: with hindsight I wish I had worked with the HW folks, I would have learned a lot!)

Can anyone recommend a UK based PCB manufacturer for simple home/hobby PCBs? Only looking for small run of some test boards #electronics #pcbs

The legacy of ‘forever chemicals’
A "study was conducted on dolphins stranded on the Victorian coast between 2002 and 2022. Foord says that nearly two-thirds of all specimens, and 90% of the endangered Burrunan, recorded PCB and DDT levels greater than health thresholds, potentially contributing to the deaths of some individuals."

Ensamblado de #circuitos o #pcbs en España. Quien haya visto las placas de #Staticboards sabe la calidad. La marca sigue viva.

Today my new #PCBs arrived. The first is an adaptation of Stefan Wagner's #C64 Power Guard: https://oshwlab.com/wagiminator/c64-power-guard
I changed some components to what I had available. Thanks @aislerhq for manufacturing them.
Only I messed up two small details. The second #comparator is backwards, so the error #LED is practically the same as the power good LED. And I also put in the #MOSFET backwards. I'll try to mount it on its back and rotated tomorrow.

Been an age since I placed an @oshpark order for #pcbs ... they really do rock in terms of customer service and ffir certain projects they can't be beaten on price. #CreditWhereCreditIsDue
They don’t make #PCBs like they used to.
#israel #palestine : #war / #gaza / #civilianwarvictims / #statistics / #pcbs
„The population of Gaza has fallen 6 per cent since the war with Israel began nearly 15 months ago as about 100,000 Palestinians left the enclave while more than 55,000 are presumed dead, according to the Palestinian Central Bureau of Statistics (PCBS).“
Before I try to reinvent the wheel, is there already an established framework for smallish stackable #PCBs?
I want to be able to stack a bunch of boards, as close to 100*100mm as I can get, without going over.
The Raspberry Pi HAT template might work, but it's a bit small and I'm not sure I actually want to use a Raspberry Pi.
Das ist ja auch speziell und HF auf #PCBs können nicht alle
Wenn ich es vermeiden kann, nutze ich nach wie vor Freiluftverdrahtung wie früher.

[13:05] Josephine, Fien en Zoë vallen in de prijzen tijdens Peace Poster Contest van Lionsclub Hoogeveen
Leerlingen, van groep 8 van de PCBS De Regenboog, zaten donderdagochtend met gezonde spanning te wachten op de uitslag van de Peace Poster Contest. Een afvaardiging van Lionsclub Hoogeveen maakte de uitslag bekend en deelde prijzen uit.

New #hardware incoming! 🚀
A fresh batch of our #MoleNet #PCBs is now in production and should arrive soon. We’ve added optimized interfaces, on-board #sensors, and low-power improvements to enhance key applications like #environmental monitoring, #IoT education, and evaluating communication technologies such as #LoRa, #WiFi, and #BLE.
Stay tuned for updates!
Well, it looks like I'm just about ready to order #PCBs, if I can get my ENS160 to give me half-reasonable CO2 estimates.
Dayton Daily News investigation found #contamination, sick workers at #PiketonOhio plant
By Lynn Hulsey
May 15, 2019
"A polluted former #UraniumEnrichment plant in #Piketon closed years ago but it's impact continues to resonate through the community, including this week when a #MiddleSchool was closed after traces of radioactive #neptunium were found at an air monitoring station at the school.
"Contamination with radiation and multiple toxic substances at the former Portsmouth Gaseous Diffusion Plant led to an ongoing, multibillion dollar environmental cleanup and sickened plant workers who had to fight for compensation as they battled debilitating terminal illnesses related to their years at the plant.
"A massive 2006 investigation by the Dayton Daily News found five plumes of poisoned #groundwater, contamination with radiation, #beryllium, polychlorinated biphenyls (#PCBs) and #asbestos.
"The investigation found lax safety practices, routine mishandling of toxic and #radioactive material and at least 400 accidental releases of #UraniumGas or toxic fluorine. Toxins were dumped into unlined #landfills and ditches and leached into #groundwater and the Little #BeaverCreek, a tributary of the #SciotoRiver.
"The plant was operated by the federal government and contractors from 1954 to 2001 and enriched uranium to high levels for #NuclearWeapons and #NuclearSubmarines and to lower levels for #nuclearpowerplants.
