#Tariffs on #PCBs change like the weather. My understanding is it's because the law allows the president to single-handed impose these #taxes in an emergency. There's no standard, so the president really wanting it counts as an "emergency". We need reforms so one person cannot raise taxes on a whim!

What good are #TreatyRights if the fish are poisoned?

Monday, July 14, 2025
By George Ochenski, Daily Montanan

"By virtually any measure, the #ConfederatedSalishKootenai Tribal Nation is an incredible success story against all odds. Forcibly removed from their homeland in the Bitterroot Valley, despite not having waged war against the white settlers or army, their own '#TrailOfTears' brought them to the Flathead Valley to live within the boundaries of the vastly reduced lands they retained in the #HellgateTreatyOf1855.

"Although the #HellgateTreaty is widely regarded as one of the best treaties signed by any of the nation’s #IndigenousPeople, even land supposedly reserved for the exclusive habitation of the #SalishKootenai was opened to purchase by non-tribal #settlers by the #DawesAct of 1887.

"The act’s intentions were to allocate reservation lands the tribes already owned to individual families as private property and, as part of the 'civilization' of #NativeAmericans, it required tribal members to register with the federal government to receive their 'allotment.'

"The entire debacle was part of the #AllotmentAndAssimilationEra from 1887 to 1934. Simply put, the federal government’s plan was to force Native Americans to be 'assimilated' into #EuropeanAmerican culture.

"Importantly, any reservation lands not allocated to tribal members was deemed
'surplus' land and opened to purchase by non-tribal settlers. This excursion into #ReservationLands was further exacerbated by the ability of tribal members to sell their allotment parcels to non-tribal members.

"The fracturing of the Salish-Kootenai’s tribal lands through sales to non-tribal members continues to cause serious problems today, including the long and on-going battle to retain their #water, #hunting and #fishing #TreatyRights.

"Article III of the Hellgate Treaty could not be more clear regarding the Tribe’s fishing rights: 'The exclusive right of taking fish in all the streams running through or bordering said reservation is further secured to said Indians; as also the right of taking fish at all usual and accustomed places…'

"Yet, just last month the Confederated Salish-Kootenai Tribal Nation issued a very serious warning to tribal members regarding the fish they have treaty rights to catch because they are poisoned.

CSKT Fish Consumption Advisory

"The Confederated Salish and Kootenai Tribes issued a fish consumption advisory on June 24, 2025, warning tribal citizens not to eat fish due to the presence of Polychlorinated biphenyls (#PCBs), #dioxins and #furans at levels deemed unsafe for humans: Source: Confederated Salish and Kootenai Tribes

"The #FishConsumptionAdvisory urges 'all tribal members to avoid consuming all species and sizes of fish harvested from the lower Clark Fork River from the Bitterroot River near Missoula to the Flathead River near Paradise. Recent testing has confirmed the presence of polychlorinated biphenyls, dioxins and furans in fish at levels that are unsafe for consumption by Tribal peoples. It is also advisable to avoid consuming rainbow trout and northern pike harvested from the Bitterroot River and the upper Clark Fork River above the Bitterroot River to Rock Creek, and, to avoid consuming rainbow trout from the Blackfoot River.

"As the Advisory explains: 'These contaminants pose a health risk to all fish consumers, and an even greater health risk to the most sensitive members of the Tribal population including women of child bearing age, pregnant nursing women, and young children. These contaminants have been linked to negative health effects in the immune, and nervous systems and may be associated with birth defects…PCBs and dioxins are classified as probable and definite #HumanCarcinogens, respectively.'

"So what good are treaty fishing rights if you can’t eat the fish because they’re poisoned? Are they really 'rights' — or is this just another in our nation’s long and shameful history of abrogating its treaties with Native Americans?

"Moreover, #Montana’s poison fish affect us all. Just as our government has failed the Salish-Kootenai, they have likewise failed to uphold our rights to the 'swimmable/fishable waters' guaranteed by the #CleanWaterAct — because no one, tribal or non-tribal, is immune to poisoned fish."

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!)
#pcbs #retrocomputing

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.

#LandBack at #Barnhart:
Contextualizing the Re-occupation of #BarnhartIsland in Shared Legacies of Struggle

From #TurtleIsland to #Palestine, the struggle at #Akwesasne is rooted in the shared struggle of all #OppressedPeoples of the world who are opposing the illogic of #SettlerCapitalism and the endless violation of the #lands and #waters that our current economic system necessitates.

"On May 21, 2024, a group of eight Kanien’kehá:ka (#Mohawk) community members from Akwesasne were arrested at Niionenhiasekowa:ne (Barnhart Island). Certain individuals among the '#Akwesasne8' had originally gone to Barnhart to exercise their right to build a hunting and gathering shelter on their own territory, in part to protest an ongoing land claim settlement that threatens to hand over Kanien’kehá:ka title to this island, among other traditionally held territories, to New York State. The settlement is being negotiated between New York entities and three Akwesasne government councils.

"Presently, the settlement negotiations would require the extinguishment of Mohawk title to Barnhart Island, which would be effectuated through an act of Congress. By asserting their right to the land, the #Akwesasne8 have sent a clear message to both negotiating parties. Barnhart Island, like all other territories illegally stolen and swindled from their community, is not for sale—particularly not by collaborationist band and tribal council entities that purport to represent the full community but that were in fact historically imposed upon it at gunpoint.

"The fact that a group of eight community members was surrounded within just a few hours by approximately 35 police agents (including both border patrol agents and state troopers) is a clear indication of the strategic significance of this island to the interests of settler-capital. As Taiewennahawi (Marina Johnson-Zafiris), one of the eight arrestees, explains in her article 'Akwesasne and the History of #Hydropower,' the Moses-Saunders #hydrodam, located at the east end of Barnhart Island, is one of the many dams along the St. Lawrence Seaway that has supplied 'cheap' electricity to an unending procession of heavily #polluting factories since the 1950s.

"For decades, dirty plants like #Alcoa, #GeneralMotors, and #ReynoldsMetals harnessed the immense power of the #Kaniatarowanenneh (#SaintLawrenceRiver) at the Moses-Saunders dam to manufacture aluminum, a cheap, abundant, and malleable building material that requires vast amounts of power to extract and process. Not only was hydropower-fueled aluminum production critical to New York’s economic development, it was central to the national pride and independence of so-called #Québec. Eager to assert its autonomy from Anglophone capital in the 1960s, the province began damming rivers on #Indigenous land in a frenzy of hydropower nationalism.

"Upstream on the St. Lawrence, the aluminum plants at Akwesasne used a #toxic #sludge containing polychlorinated biphenyls (#PCBs) as a hydraulic fluid during the production process. These PCBs were manufactured by the infamously litigious #corporation #Monsanto, which continues to evade public #accountability for discharging this known #carcinogen into the St. Lawrence River and onto Kanien’kehá:ka soil. The #carcinogenic soup was left exposed on the very grounds where the children of Akwesasne played and where families grew their vegetables. Today, Akwesasne sits downstream and downwind of three heavily #polluted #superfund sites, and residents of Akwesasne report that almost everyone they know has a friend or family member suffering from a rare #cancer, #MetabolicSyndrome, or #autoimmune disorder. Rare, life-threatening illnesses exist at Akwesasne at rates that the public would never consider normal or acceptable in any non-Indigenous community.

"Dana-Leigh Thompson, one of the Akwesasne 8, lived about 3,000 feet from the PCB #dumpsite of the #GeneralMotors (#GM) factory for a decade. She calls what is happening to the community nothing short of an '#environmental #genocide.'"

"#tomcod were doing remarkably well in the Hudson's #PCB-infested waters. Their livers had the highest levels of #PCBs known in nature, yet they were alive... it turns out the molecular mechanism was in a single gene... the special mutant population had receptors that didn't bind to PCBs as well... This was lightning-fast #evolution, and it created a population of #fish that are unique to #NewYork."

I've just been updating my PCB page on my blog: diyelectromusic.wordpress.com/

It lists all my MIDI and audio related PCBs so far that I've made for Raspberry Pi (V3/V4, V1, Zero, 400); Raspberry Pi Pico; Arduino Uno; Arduino Nano; Seeed XIAO; and a few other odds and ends.

It also provides the context for the use of the designs and links to all the relevant design and build notes.

Simple DIY Electronic Music Projects · PCBsRecently I’ve started detailing the design and build process for a number of projects based on custom designed (by me) and made (using a PCB fabrication service) printed circuit boards. …

Day 240 of #PCBs

And, it turns out that one of the pieces of equipment that I wanted to mount, that I thought was a standard 1/4 DIN mount, was most definitely not.

Here's what that monster wants for a panel cutout:
