    Anyone in Europe got a spare Tag Connect TC2050-IDC-NL they&amp;#39;d sell to me? When new, they seem to cost a fortune. Ali* also does not seem that cheap.

    Woohoo! My DiyIrTower PCBs have arrived! (&quot;Do-it-yourself infrared serial communication tower (compatible with LEGO IR serial tower)&quot;) See also: https://github.com/maehw/DiyIrTower, https://github.com/maehw/WebPBrick/ #WebPBrick #KiCad #OpenHardware #electronics

    Oh noes, what have they done? Better sounds for the Star Wars sets? Initial sounds for the upcoming Pokemon sets? Enabled the microphone? Will the firmware be downloaded from the Bilbo backend — or did they integrate another assets file into the APK? Finally, OTA could be sniffed (BLE-wise), I guess. #LEGO #SmartPlay #SmartBrick #reverseEngineering #ble #Android #apk

    Oh, I had expected #LEGO to make it official next month, but they already did: after Star Wars, Pokémon is the next theme with #SmartPlay features. 12 sets ready to pre-order. &amp;quot;Cheapest&amp;quot; &amp;#39;all-in-one&amp;#39; (imem including the #SmartBrick) set is &amp;#39;Training House with Pikachu&amp;#39; for $69.99, &amp;quot;cheapest&amp;quot; &amp;#39;compatible&amp;#39; is &amp;#39;Jigglypuff Concert&amp;#39; for $14.99. If you have money and love Pokémon, there&amp;#39;s &amp;#...

    #gpn24 fomo. Wäre dieses Jahr sehr gerne das erste Mal auf die #gpn gekommen, aber es gab leider eine zeitliche Überschneidung. Viel Freude allen, die teilnehmen können.

    Hallo zusammen. Ich würde gerne ganz legal zwei #Fotos von #Shutterstock kaufen, habe aber keinen Account und kein Abo — und möchte das für zwei Fotos auch nicht. Hat von euch wer und würde mir gegen Geld zwei Fotos von deren Kontinent abdrücken können? Nicht für Print sondern Web benötigt bzw. auch eine öffentliche Präsentation mit Aufzeichnung.

    Silicon die shots of the #LEGO #SmartBrick appeared! Thanks @infosecdj for the amazing work! https://infosec.exchange/@infosecdj/116539170723262718

    Some day I will find more time to look at the logic analyzer traces of #LEGO #SmartBrick. While the extension &amp;quot;SPI Flash&amp;quot; by Adafruit did not work, &amp;quot;SPI Memory Analyzer&amp;quot; by Thomas Poms does a good job in decoding the communication with the Winbond SPI flash. In the current trace I&amp;#39;ve only seen &amp;#39;Read Data&amp;#39; (0x03) and two &amp;quot;unknown&amp;quot; commands which the HLA is unable to decode: &amp;quot;Power-down&amp;quot; (0xB9) and &amp...

    Maybe, there&amp;#39;s some other folks using the #Saleae logic analyzers here (or their UI + decoders aka analyzers). So I thought, I could share this question here as well: 🧵 ❓ &amp;quot;Adding a missing SPI chip select signal / decoding a single device without CS&amp;quot; https://discuss.saleae.com/t/adding-a-missing-spi-chip-select-signal-decoding-a-single-device-without-cs/3714 #logicAnalyzer #hardwareHacking #spi

    Woohoo, jetzt wird es &amp;quot;ernst&amp;quot;. 😃 &amp;gt;Hi! Wir freuen uns dir mitzuteilen, dass wir deine Einreichung “Hacking LEGO Smart Play – was steckt hinter den „magischen Steinen“?” für TDF5 akzeptiert haben. Gerne Input im Vorfeld, falls es wünsche gibt. 🙃 #tdf5 #hacking #LEGO #SmartPlay #SmartBrick

    Is there a chance anyone here has a EMDVK9305SOC — an eval board for the EM Microelectronic EM9305 (&amp;quot;em | bleu&amp;quot;) Bluetooth microcontroller/SoC which they don&amp;#39;t need anymore? Or a logic analyzer trace of the SPI HCI programming (and optionally also including the UART of the USB/serial interfaces) the NVM with some blinky example using `blengine`?

    Hi! I an looking for help on visualising multiple system states of a complex distributed system over time. I don&amp;#39;t want to reinvent the wheel if I don&amp;#39;t have to. I want to visualise arbitrary system states — not only OS tasks. And additionally, also event data and waveform data. I want to zoom into the data on the timeline. I&amp;#39;m addition to the time dimension, another view with the state transitions seen works be great – with transitions arrow thickness being weighed by fr...
