Sipeed NanoKVM: A RISC-V stick-on This is the Sipeed NanoKVM. You stick it on your computer, plug in HDMI, USB, and the power button, and you get full remote control over the network—even if your computer locks up. How did Sipeed make it so small, and so cheap? The 'full' kit abo … | Continue reading
What happens when you touch a Pickle to an AM radio tower? A few months ago, our AM radio hot dog experiment went mildly viral. That was a result of me asking my Dad 'what would happen if you ground a hot dog to one of your AM radio towers?' He didn't know, so one night on the wa … | Continue reading

If AI chatbots are the future, I hate it About a week ago, my home Internet (AT&T Fiber) went from the ~1 Gbps I pay for down to about 100 Mbps (see how I monitor my home Internet with a Pi). It wasn't too inconvenient, and I considered waiting it out to see if the speed recovere … | Continue reading
Installing Ansible on a RISC-V computer Ansible runs on Python, and Python runs on... well pretty much everything. Including newer RISC-V machines. But Ansible has a lot of dependencies, and some of these dependencies have caused frustration from time to time on x86 and Arm (so h … | Continue reading

The Cicadas are Here There are annual cicadas. Then there are 13-year cicadas. And 17-year cicadas. Then there are days like today when 13 and 17 year cicadas emerge from the ground around the same time, creating a fairly odd event in our backyard. My daughters are helpfully poin … | Continue reading
