What is new Windows ARM Support for Windows on ARM CPUs. Fritzing uses Prism on Windows 24H2 to run on ARM. New Fonts We are fading out Droid Sans and Open Sans in favor of Noto Sans. This affects mostly the Breadboard and the Schematic View. A bunch of Fritzing parts was using unknown fonts, which resulted in using whatever fallback font the operating system provided. We have replaced these with either Noto Sans,...

Comments to USTR Opposing Tariffs and Tariff Increases

The United States Trade Representative invited comments from the public this past month to assist them in making recommendations about how to address so-called “unfair trade practices by other countries” and “non-reciprocal trade relationships”. This is the public comment I left today on the USTR docket. I have also submitted similar comments to my senators and representative in Congress.

“I am deeply alarmed by the Trump administration’s decision last week to impose tariffs on Canadian and Mexican goods, as well as further increase tariffs on imports from China. As the CEO of Great Scott Gadgets, a small Colorado-based business that designs,...

Robotron S6130 — Восставший из мертвых

История ремонта этой пишущей машинки тянется уже 8 лет! Шутка что ли, это Самый Первый Артефакт моего YouTube-канала!

Robotron S6130 — многофункциональная пишущая машинка формата A2 на базе процессора Z80, с функцией запоминания набранных текстов во встроенной оперативной памяти, с записью и воспроизведением на магнитофон, а также возможностью приема и передачи текстов с ЭВМ по последовательному порту!

Но, перед тем как появиться у меня, агрегат порядка четырех лет пролежал в сыром, заброшенном помещении на горе заплесневевших книг. За это время питающая ОЗУ резервная батарейка протекла и пожрала дорожки на материнской плате. Коррозией покрылись и ноги ближайших микросхем, ОЗУ. Разумеется, на первом...

We’ve recently published the second video in our Cynthion training series, so if you want to go deeper into exploring and experimenting with USB, this is for you. In this video, Martin explains the basics and evolution of Facedancer and demonstrates how to use Cynthion and Facedancer to emulate a PS5 controller. If you haven’t already, check out the first video- Sniffing PS5 Controller Packets with Cynthion.

Repurposing Cisco power supplies

Sometimes you can find a good deal on used power supply from various vendors. In my case it was Cisco C3K-PWR-750WAC and RPS 2300. The problem is, that they don’t output any voltage until they are plugged into device. The question is, how to fool them into thinking they are plugged in. Update: including N2200-PAC-400W

The spec for the supply looks good:

And the interface is following:

You can see, there are some huge terminals which will obviously be power output and then 16 2.54mm pins where the detection will most likely happen. I was thinking how to find...

Chinese PoE extractor teardown

I needed to power some cameras using Power over Ethernet but they only supported 12V input, so I ordered some PoE extractors from ali. Here they are for your information.

They both only support 100Mbps over 2 pairs. The wateproofing was quite annoying to remove but not impossible. It seems they both can be modified to support different input/output voltage. As you can see in the pictures, they are both using H6225K step-down regulator in a very similar design.

The circuit mostly corresponds to following schematic found on the internet:

Thank you for your attention.
