The RockBLOCK Mk2 allows you to send and receive short messages from anywhere on Earth with a clear view of the sky and it works far beyond the reach of WiFi and GSM networks. Maybe you want to transmit weather information from mid-ocean? Or use it to control your robot in the middle of the desert? Perhaps you need to communicate in an emergency, when other networks might not be available? RockBLOCK can help you.

At the heart of RockBLOCK is an Iridium 9602 satellite modem. The RockBLOCK provides the 9602 with an antenna and an 0.1" header with power and data connections. The header includes an FTDI-compatible serial interface that you can connect directly to almost any microcontroller, or via FTDI Basic Breakout to a computer?s USB port. The RockBLOCK requires a 5V supply that can supply 470mA during startup, and 100mA continuously. Sleep mode can reduce this to 20uA. Alternatively you can power the RockBLOCK with a 3.7V Lipo battery that can supply up to 1500mA. See the Developer?s Guide below for more information.

Iridium is the only satellite network that allows transmission of information from any point on Earth ? other networks have no coverage in the polar regions, and have intermittent or no coverage in other marine and land areas. Iridium has 66 satellites in orbit around the Earth, allowing coverage anywhere on Earth 24 hours a day, 7 days a week. No other satellite network has truly global coverage. Messages sent via Iridium take just seconds to reach you, via e-mail or directly to your web-service.

Note: The RockBLOCK does require a monthly rental service to exchange information with the Iridium satellite network. You only pay for months in which you wish to use the RockBLOCK. No annual contract is required. Line rental costs �8GBP (about $12USD) per month and includes access to The CORE management system for managing your devices. The billing system is built into the CORE, and allows you to pay for only what you use. Check the CORE Information Page link in the Documents section below for more information.

Features:

  • Plug and play satellite communication
  • Full 2-way communication system
  • Integrated antenna and power conditioning
  • Truly global operation, using the Iridium satellite network
  • Data arrives via e-mail, or directly to your own web-service

If you have sensitive skin and dont want premium prices, Cremo’s body wash is an excellent option A+
Scent: Palo Santo, Size: 16 Fl Oz (Pack of 1), Scent: Palo Santo, Size: 16 Fl Oz (Pack of 1)
Cremo’s body wash for men has become a staple in our household. The product exudes a luxurious feel, from the rich lather to the clean, long-lasting scent that genuinely resembles a more expensive fragrance. This body wash possesses a pleasant aroma of cardamom, papyrus, and most notably, palo santo. It features a warm, woody, and spicy scent, which is one of my preferred fragrance notes. Notably, the scent is strong without being overpowering. Additionally, I appreciate the aesthetic appeal of the bottle. The exquisite and vintage-inspired packaging complements the fragrance effectively. What truly sets Cremo’s body wash apart is its gentle nature. I have sensitive skin and this body wash does not cause dryness or irritation. In fact, it leaves my skin feeling soft and smooth, which is not always the case with other brands I have tried. The affordability of Cremo’s body wash is a significant advantage. It offers a high-end feel and fragrance without incurring excessive costs, making it an easy choice for repeat purchases. If you or your family have sensitive skin or simply desire a pleasant scent without paying premium prices, Cremo’s body wash is an excellent option. Highly Recommended. 5/5 Stars.

Beat the Humidity with This Citrus Powerhouse
Scent: Bergamot, Size: 16 Fl Oz (Pack of 1)
​In the middle of a brutal, humid Philippine summer, finding a body wash that actually boosts your confidence is a game-changer. Cremo’s Italian Bergamot isn’t just a soap; it’s a full olfactory experience. It opens with a vibrant, tart Italian bergamot that immediately cuts through the heat, followed by the freshness of vetiver, and the neroli blossom adds a sophisticated floral touch. ​True to Cremo’s Reserve collection, the scent is beautifully layered. It builds in intensity as you lather, allowing the earthy, fresh vetiver to anchor the citrus. Unlike many drugstore options, this lingers—stepping out of the shower, you can still catch the crisp citrus and the clean, woody dry-down on your skin. It’s the ultimate reset for a hot day.
