I have a really cool project in mind for this new ESP32 variant www.espressif.com/en/news/ESP3...

I got a 32x32 pixel board from Action and used the NS API to make a map of delayed/canceled trains in The Netherlands. I'm using the PyPixelColor library to send the data via Bluetooth to the panel. Red = at least one delayed train Blue = at least one canceled train
A 32x32 pixel board with a 3D printed diffuser placed on the face of the device. Multiple pixels are lit up with some resemblance to the shape of The Netherlands. 3 colors are in use on the pixels: green, red, and blue. The majority of the illuminated board is green with various red pixels and a small number of blue pixels dotted around. Many parts of the board are dark with unlit pixels showing the approximate border of The Netherlands.An open box stating "B.K Light LED pixel board" resting on top of a laptop keyboard. The laptop display is partially visible showing a map of train lines in The Netherlands.

It seems like Cloudflare is unhappy at the moment. A lot of pages protected with their WAF are just returning 500 internal server error

Want to learn how to erase the supervisor password on a ThinkPad X13 G1 without knowing it? I documented the process here: jhewitt.net/thinkpad_x13... This attack vector works on some other models too but was fixed on models released in/after 2021.

I'm looking at this area of a ThinkPad motherboard with illicit intent.
A small magnified section of a ThinkPad motherboard PCB. A large unpopulated connector labeled "JTAG1" is visible with a "Lenovo ThinkEngine 62D518FTG" IC chip below. The board also features a selection of resistors, capacitors, and other small components which are not the main focus of the image.

Finished editing the photos from @why2025.bsky.social and really like the vibe of this shot from one of the foggy evenings.

I bought a 5th gen iPod Classic released in 2005 and decided to recover the deleted files from the HDD since I was curious what kind of life it had. Fun to see that some of the original music synced in 2006 is still there. There was frequent activity between 2006-10, then for a few months in 2022.

Went for a walk recently and met this friendly cat :) This photo was taken on Kodak Vision 500T 35mm cine film which I developed at home.
Orange cat with small patches of white, stepping onto grass in the direction of the camera

Deactivated my Twitter account today. Still being on that platform after recent events just feels dirty.

The relative humidity in my apartment averages around 30% so I got a humidifier. I tried to avoid it, but the one I got was an ultrasonic version (the site didn't say that though 😑). This graph shows the particulate matter (PM) after running it, since it vaporizes all of the impurities in the water.
A line graph with particulate matter (PM) on the X axis and time on the Y axis (January 10th at 18:00 to January 11th at 15:00). The PM value is often at 0, but shows 2 periods where it exceeds 100, reaching as high as 175. The first period is around 19:30 until 22:30 on January 10th where the average is around 120. The second period is around 09:15 to around 15:00 on January 11th where the average is around 130.

My Olympus OM-1 film camera jammed recently and I decided to look inside to see if I could find any obvious cause. I suspect the previous owner was a little rough with it because some plastic on this gear was snapped and the shard had jammed the mechanics. I removed the shard and now it works again.

I put a bunch of these small E-ink grocery pricetag displays running OpenEPaperLink around my apartment. I'm running StableDiffusion on my home server to generate AI cat pictures and push them out to the tags.

I finally received and built my uConsole; a handheld Raspberry Pi based portable computer.

I'm testing some wireless epaper displays. I now have them integrated into our home automation meaning I can display stats or random cat photos from an API.

I got a used ThinkPad T480 today, happy to see it is configured to use an M.2 drive rather than SATA. I have spent the last few hours stress testing it and saw no stability issues. I have a new 1TB SSD and 2x16GB RAM sticks arriving tomorrow to upgrade it with.

Hello 👋 I recently made this account because I'm becoming more unhappy with Twitter each day. I often post about wardriving, software development, custom hardware, and cybersecurity. Feel free to follow if any of those things appeal to you.
