Are you looking for an introduction into "Software Defined Radio", especially together with Linux? I'm introducing the basic concepts, and software gprx and OpenWebRX+. Might contain segways into #HAMradio . 😃 Slides: fluxcoil.net/files/presen...

At #39c3 , HAMs presented about their radio contact with Fram2, a spaceX mission. We will discuss this on Friday, January the 16th, in #Tokyo ( 7pm, room #202 at Jiyugaoka Juku Center ) at the local club - come over if you are in the area! Recording in German: media.ccc.de/v/39c3-amate...

My steps to emulate the #Amiga 1000 keyboard with the Raspberry Pi: blog.fluxcoil.net/posts/2025/1...

I finally found the time to connect my Morse key to the computer, worked out as simple as I hoped - the Morse key is simply shortening a circuit, which is the same as mouse button switches are doing. So now I can also practise to give CW. Details: blog.fluxcoil.net/post/2025/12... #HAMradio

Tokyo at night, near the emperors palace

We do an evening around #LoRa devices and #Meshtastic on Friday. - What are Lora, how does Lora relate to WiFi - What's Meshtastic, will bring in some devices - I'll explain this BBS use case idea, how it works Location: Nov 21st, 7pm, Meeting room 202 at Jiyugaoka juku Center, Tokyo

It is November, and that means "Butt Sumo" (尻つみ祭り) time again at the local shrine here in Ito, #Japan. Contestants stand back-to-back on a raised dais and, at the signal, attempt to bump their opponent off. The winners are sometimes surprising.

Drop by the Tokyo Linux User’s Group booth at OSPN OSC and convert your PC to Linux today!

Tried to replicate an old style BBS connection over #meshtastic devices, like we had over phone lines in the past. Not just simple message push/pull, all the blinkenlights! Details: blog.fluxcoil.net/posts/2025/1... #lora #meshtastic #ham
