I recently got ahold of Atari STF. It wouldn t start, not even an LED, so it needed some work. After opening the case and exposing the power supply nothing looked suspicious (no blown caps). Then I proceeded to measuring the voltages. The power supply is a separate board with easy to remove header leading Continue reading Repairing Atari ST(F) with bad power supply
I was recently investigating driver issues on my home firewall with Intel network cards, and noticed something that spiked my attention. Intel s PCI Vendor ID is 0x8086 which is a nice homage to their glory days. What did I do next ? I scanned the entire PCI ID database looking for fun and unusual Continue reading PCI Vendor ID rabbit-hole musings
I did it again!.This year, I gave a talk on reverse-engineering a commercial coffee machine. Clarification, the title was supposed to be Sudo Make Me a Coffee: Adventures in Reverse-Engineering a Commercial Coffee Machine (Sudo without comma, referring to UNIX command sudo) Video recording has been posted on Youtube:
Oh what a weekend it has been. I not only attended the in-person Supercon (after 2 year of remoticon “hiatus”) but also had the pleasure to give a talk.I submitted my proposal for a talk focused on my experience cracking encrypted software and to my surprise it got accepted. I got the first slot on Continue reading Hackaday Supercon 2022
Starting July 12th 2021, the PSU converter boards for SGI Fuel will no longer be available to order via eBay. eBay has implemented some changes to their selling system that made it increasingly difficult to sell stuff, and despite my attempts to resolve it with their support was unable to fix anything. My boards Continue reading Silicon Graphics SGI Fuel ATX Power Supply converter boards ordering…
Pyramid PS36KX is one of the few power supplies I have for my radios. Recently I decided to consolidate and hook up more radios to a single PSU via powerpoles, it makes everything easier. One problem with the Pyramid is noise, it s *extremely* loud, with just a single fan. Pop goes the chassis, one cheapo Continue reading Silencing HAM Radio power supply Pyramid PS36KX
I kept at it, and got it to work without any static configuration (but still have to use NAT) I still need the NAT rule, and what s strange is that the workstation gets IP address from /56 prefix (which is configured as the WAN prefix on the modem): my pfSense receives this IP via DHCPV6: Continue reading Native IPV6 with TWC part 2
I ve had cable Internet from Spectrum for about 3 years now, and about a year ago I started using pfSense as additional firewall (it s easier for me with many VPN s that I use, since I can terminate IPSec and OpenVPN on the pfSense). Thing is, the IPV6 never worked for me via pfSense for some Continue reading Native IPV6 via pfSense on Charter/Spectrum/TimeWarner
Just stumbled on this article https://jcs.org/2018/06/12/airport_ssh and I just had to try it out on my Airport Express, even though the method was for the Extreme. It worked like a charm, as easy as: python -m acp -t 192.168.234.189 -p xxx --setprop dbug 0x3000 python -m acp -t 192.168.234.189 -p xxx --reboot Dmesg: ry = Continue reading NetBSD on Airport Express
Got around to setting up IPSec between my OSX and Linux server, it worked just fine with PSK (pre-shared key), but failed when using certificates, the error on the server side was: generating ID_PROT response 0 [ KE No CERTREQ NAT-D NAT-D ] I enabled debugging of racoon on OSX (add the 2 lines to Continue reading IPsec (OSX to Linux) with Certificates
