#ThrowbackThursday: #AgentShredder #EMV Test im EMV Labor Leipzig.
#ThrowbackThursday: #AgentShredder startete als 100% #DIY Projekt. Mittels #RTLSDR lassen sich erste #EMV Tests anstellen und der Effekt von Schirmung testen. Das erspart möglicherweise zusätzliche Besuche beim EMV Labor.
OTD 1995: #Legato Systems IPO. My brother Bob was a founder. Red Herring available here: https://drive.google.com/file/d/1dSkk_muRnVtKcFOj50hNL_gap6joiTF2/view?usp=sharing Later acquired by #EMC.
Wouhhh, sujet d'#EMC sorti au Brevet des collèges en Amérique du Nord
L’IA CONTRE LA SOCIÉTÉ
Le discours porté par les pouvoirs économiques et politiques qui la soutiennent est bien rodé : l’intelligence artificielle (IA) constitue une rupture majeure à laquelle il faut s’adapter, en limitant ses éventuels méfaits – présentés comme autant de défis.

You may remember my post about the completely failed EMC test from about 3 weeks ago - I finally got proof of what the issue was: the EMC test lab bodged the test method and didn't ensure proper impedance on the measured cable.
The two attached graphs are from the same device, but just one measurement is done properly...

Was at the EMC test lab for work today - and I guess I've got a bunch of extra work ahead
This is conducted emissions on the ethernet port. The device needs to meet category B, so the lower two lines are the limit...

From memory, it will try to PXE boot if it fails to boot normally.
Specify typical TFTP server and file options in DHCP.
Feed it an x86 OS that uses serial console without VGA and you’re probably booting.
You can also interrupt the Trident POST (?) with Control-C (don’t use escape any more), provide the shipping password — I don’t know if the database password suffices or not — choose — from memory — the data directory menu option (28?) and PXE boot.

. @profsdocs . Les professeurs documentalistes sont enfin nommés "Coopération"
avec les collègues d'Histoire-Géographie
? Qu'en pensez-vous ? Personnellement je suis optimiste. ..mais je le suis peut-être trop

#Rotterdam press conference: a 32 year old student has shot & killed his neighbour, wounded her 14 y/o daughter, then shot & killed a professor in the #EMC hospital. He set fire to his (or her) house and the hospital.
He has been detained. Police are unclear if there are any other victims.

Situation de #racisme à l'école ?
La dernière fois que j'ai dû aborder ce thème difficile, j'ai utilisé la chanson "Lily" de Pierre Perret aux élèves dont j'étais l'éducateur.
La professeur d'histoire (PP de la classe concernée) semble intéressée mais ne connaît pas cette chanson.
Je la lui partage illico !
Elle compte l'utiliser pour son prochain cours d'#EMC !
Un bel exemple de #collaboration autour d'un café en salle des profs.

Mini-PCIe wifi, with both PSB and additional antennas.
The main SoC is also heatsinked and apparently needed some aluminium foil tape on the HDMI traces to pass #EMC.
Anyone got a good design guide or appnote for conducted emissions filters on loads that switch in the 150-300kHz range?
Looking for something that goes into detail on Pi filter design for power delivery across a range of load currents, with guidance on inductor and capacitor selection. Ideally also covering practical issues like filter resonance, load-side ripple current and tangent losses, ballpark values for relevant parasitics, etc.
Boosts welcome.
