SIM card or a CPU




The SIM cards in cellular telephones might be smaller than a postage stamp and less than a millimeter thick but that hasn't stopped South Korea's SK Telecom from cramming all the major components needed to run Google's Android OS inside one of them.

The carrier's Android SIM, a prototype of which is on show at this week's Mobile World Congress in Barcelona, includes an ARM-based processor, companion memory and 1GB of flash memory to store the OS and other data.

SK Telecom envisages such a SIM card could be used between a number of "dumb" terminals -- devices that have ancillary peripherals such as a screen and keyboard but lack a processor and pre-installed OS. The SIM card uses the USB 2.0 interface to communicate with the terminal.

All of the user's applications and data are stored alongside the OS in the SIM card, so the user's desktop could be transported between devices by switching the SIM card between them. For example, a PC desktop could be switched into a cell phone for a commute.

SK Telecom said it's only a prototype at present and there are no plans to bring it to market but its development shows the level of miniaturization and amount of hardware that can be crammed inside a cell phone SIM card.

In April the carrier, which is South Korea's largest mobile operator, will roll out a series of customized SIM cards preloaded with applications and other data. Several "smart SIM" cards are being demonstrated at Mobile World Congress. They include a financial SIM that includes an application to monitor markets, a SIM branded by a pop group that includes their music videos and a sports-themed SIM from a soccer club.

SK Telecom is also experimenting with a SIM card with built-in wireless electronic money function. The card could be used to add wireless e-payment to handsets that don't have such a feature built-in.

Also this week at Mobile World Congress, SIM card-maker Sagem Orga showed off its SIMFi -- a SIM card with built-in Wi-Fi hotspot so that computers and other devices can connect to the Internet through the SIM card and phone's wireless connection.

ESP32-C6 Wi-Fi Logger with Browser GPS + Heat Map Dashboard

This project is an ESP-IDF firmware for the Seeed Studio XIAO ESP32-C6 that turns the board into a self-hosted, secure Wi-Fi scanning logger. It creates its own access point, serves a responsive HTTPS web UI, logs nearby Wi-Fi access points, optionally tags rows with GPS coordinates (provided by the client browser), and exposes battery status from the on-board LiPo input. The end result is a pocket Wi-Fi “survey” tool: scan, track, export logs as CSV, and generate a heat map view to visualize RSSI vs location. Project overview and feature set: :contentReference[oaicite:1]{index=1} What it does AP + Station mode so the device can serve the dashboard while scanning nearby Wi-Fi networks. HTTPS web interface using a bundled certificate/key for local secure access. Single scan and continuous tracking modes. CSV export for analysis and archiving. Persistent logging to SPIFFS at /spiffs/logs.csv . Battery monitoring via ADC with voltage/percentage/status sh...

סלקום ממש לא כדאי לקנות מאצלכם מודים

סלקום באמת מבאס לגלוש אתכם !! בשעה טובה ומצלחת קניתי מודם סלולארי על מנת שאוכל לגלוש באינטרנט בעזרתו. בעמדת המכירה הציעו לי את מסלול תשלום מראש הידוע כtalkman, מסלול זה התאים לצרכי כך שאוכל לדעת מראש כמה אשלם ובחרתי לבצע את העיסקה. כאשר התחלתי לגלוש לשרתים המספקים תוכן כגון rapidshare , megaupload , zshare ועוד גיליתי כי כתובת הIP ממנה אני גולש חסומה, או עברה את כמות השימוש המותרת אולם זה קורה לפני שאני ביצעתי שימוש כלשהוא. ניסיתי להשתמש בכתובות אחרות באמצעות קבלת כתובת IP אחרת (הוצאה והכנסה של המכשיר נותנת כתובת חדשה), אולם בכל ניסיון הכתובות היו חסומות, כלומר לא יכלתי להשתמש כלל בשירות. נתון זה שהכתבות כבר בשימוש ומי שמתמש בכתובת דינאמיות חסום לא נאמר לי ולא הועלה בעת המכירה. מה שקורה שבכל אתר שאני רוצה להשתמש בו אני חסום ולא יכול להשתמש. דברתי עם מספר חברים שיש להם מודמים כאלה כבר זמן רב , כששאלתי איך לפתור : אמרו כי הבעייה נפתרה לנו ע"י שינוי בתוך המודם ל: ABN = intereal ו זה בשפה המקצועית אומר " IP קבוע" שמחתי ל פתרון ו נגשתי ל סלקום אחרי 30 דקות המתנה...

Ollama Voice Chat — A Local, Talking AI Assistant for Windows

  Ollama Voice Chat — A Local, Talking AI Assistant for Windows I’m excited to share my latest open-source project: Ollama Voice Chat — a simple but powerful local voice chat assistant that runs fully on your machine using open-source AI tools. It lets you talk to a Large Language Model (LLM) and hear its responses spoken back out loud — no cloud APIs, no monthly fees, and full control of your data. 👉 GitHub repository: https://github.com/error0327/ollama-voice-chat 🚀 What Is It? Ollama Voice Chat is an interactive client for Windows that connects to a locally running LLM (via Ollama), converts user speech to text, sends it to the model, and uses Coqui TTS to speak the replies. It includes an automated setup script to streamline installation and configuration. Instead of typing, you can talk to your AI assistant and get spoken answers — great for hands-free use cases, prototyping voice UIs, or just having a more natural interaction with your models. 🧠 Why This Matte...
