2.9″ ESPaper Lite Kit for $39.90

The 2.9″ ESPaper Lite Kit contains most of the parts you need to display data over wifi:

With the 2.9″ ESPaper module you can display data retrieved over WiFi on an ePaper with little effort. The integrated ESP8266 Wroom-02 module updates the 296×128 B&W ePaper display over the SPI bus. The module also features a charging circuit for LiPo batteries and a JST connector which allows you to run the module for weeks or even months from a battery. How long the module can be run from battery mostly depends on the update frequency and the battery capacity. In tests we could run the module from a 800mAh LiPo battery for several weeks by updating weather information every 20 minutes.

Teardown & Repair of an Agilent N1912A P-Series Power Meter

In this episode Shahriar investigates a peculiar problem with an Agilent P-Series Power Meter. While the instruments works during startup, after about 10 minutes the LCD screen begins to flicker and become scrambled. Initial investigation reveals that the issue is not likely with the main motherboard since USB connection to the instrument and data-readout is possible even when the LCD screen is malfunctioning.

The Dremel DigiLab Laser Cutter enables Makers to expand portfolio and business capabilitie.

MOUNT PROSPECT, Ill., Sept. 23, 2017 /PRNewswire/ — At World Maker Faire New York, Dremel introduces the first-of-its-kind Dremel DigiLab Laser Cutter. Dremel designed this machine to provide Makers of all levels and practices with an outlet for innovation. As the brand’s latest addition to its lineup of digital fabrication tools, it has the ability to customize a variety of materials quicker and easier than ever before.

The Dremel Laser Cutter backed by 85 years of the Dremel brand legacy, will provide a higher level of safety, ease, reliability and quality to users. This tool can cleanly slice through tougher materials like wood, acrylic, leather and paper as well as neatly engrave tougher surfaces such as glass and anodized metal. Dremel President John Kavanagh shared how the new Dremel Laser Cutter will enhance the productivity of Makers and industrial professionals across a broad spectrum of applications.

The new Dremel Laser Cutter allows a level of precision you just can’t get by hand because it is so detailed,” Kavanagh said. “It is truly designed and built for business owners to personalize any project and improve efficiency. With a higher level of reliability and ease of use, the Dremel DigiLab Laser Cutter eliminates many of the repetitive, laborious steps and allows Makers to create new projects they couldn’t necessarily do before.

3A Thermoelectric Cooler (TEC) Driver

3A TEC Driver Module is a complete power stage solution to drive Thermoelectric Cooler (TEC). The required DC voltage input controls the output current. It consists of the Texas instruments DRV593 power driver IC, along with a few discrete passive components required for operation. It also includes jumpers for configuring the features of the device, LEDs for fault monitoring, and an output filter. The 4 Pin header connector  for the inputs, 4 pin header connector for  output, and 4 Pin header connector for power supply, provide ease of connection to any system, from an existing design to a bread-boarded prototype. Connect a dc control voltage to CN1 Pin 3 (IN+), ranging from ground to VCC. The Pin 7 of the IC is held to VCC/2 with a resistor voltage divider, as shown in the schematic. Therefore, a dc control voltage of VCC/2 provides 0-V output from PWM to H/C. Input DC voltage range is 1.2V to 3.8V when supply voltage is 5V and 1.2V to 2.1V when supply voltage is 3.3V.

Features

  • 3A Maximum Output Current
  • Low Supply Voltage 2.8V To 5.5V
  • Frequency 500 KHz (Refer to Note To change Frequency)
  • High Efficiency Generates Less Heat
  • Over Current and Thermal Protection
  • Fault LED for Over Current, Thermal & Under Voltage Conditions
  • When J3-Jumper is closed, the board is configured for 500-kHz operation.

LT8362 – Low IQ Boost/SEPIC/Inverting Converter with 2A, 60V Switch

The LT8362 is a current mode, 2MHz step-up DC/DC converter with an internal 2A, 60V switch. It operates from an input voltage range of 2.8V to 60V, suitable for applications with input sources ranging from a single-cell Li-Ion battery to automotive and industrial inputs. The LT8362 can be configured as either a boost, SEPIC or an inverting converter. Its switching frequency can be programmed between 300kHz and 2MHz, enabling designers to minimize external component sizes and avoid critical frequency bands, such as AM radio. Furthermore, it offers over 90% efficiency while switching at 2MHz. Burst Mode operation reduces quiescent current to only 9μA while keeping output ripple below 15mVP-P. The combination of a 3mm x 3mm DFN or high voltage MSOP-16E package and tiny externals ensures a highly compact footprint while minimizing solution cost.

OSD335x-SM & OSD3358-SM-RED Dev Board

Austin, Texas (September 19, 2017) – Octavo Systems LLC (Octavo) announced the production release and immediate availability of its highly anticipated OSD335x-SM System-In-Package (SiP) device.  The OSD335x-SM, like the entire OSD335x family, integrates the Texas Instruments (TI) Sitara™ AM335x processor with an ARM® Cortex®-A8 core running at 1GHz, DDR3 memory, a TPS65217C power management IC (PMIC), a TL5209 low-dropout (LDO) regulator, and passive components into a single wide pitch (1.27mm) BGA package.  The OSD335x-SM enhances this integration by adding EEPROM as well and reducing the package size by 40%.

The OSD335x-SM comes in a 21mm x 21mm (0.83in x 0.83in) 256 Ball wide pitch (1.27mm) BGA. Occupying 441 square millimeters, the OSD335x-SM uses 60% less space than the equivalent system designed with discrete components.  It is the smallest AM335x processor-based module on the market today that still allows complete access to all the AM335x device I/Os including the PRUs.

“The OSD335x-SM was built to allow system designers to quickly create the smallest possible ARM Cortex®-A8 system and then easily transition into production,” says Bill Heye, President of Octavo Systems.  “By removing the need for DDR routing, power sequencing, complex supply chains and larger PCBs, the OSD335x-SM provides value across the entire life cycle of a design.  We are excited to finally release it to the market and we can’t wait to see the innovative ways people leverage this technology.”

The first 21mm device in the family, the OSD3358-512M-BSM, can be purchased today through Octavo’s distribution partners, Digi-Key Electronics and Mouser Electronics.

LimeSDR Mini – Software-defined-radio card

An open, full-duplex, USB stick radio for femtocells and more.

The LimeSDR and LimeSDR Mini are members of the same family of software-defined radios. One does not replace the other. Rather, they are complementary.

Simply put, the LimeSDR Mini is a smaller, less expensive version of the original LimeSDR. However, it still packs a punch – at its core, the LimeSDR Mini uses the same LMS7002M radio transceiver as its big sibling. The Mini has two channels instead of four, and, by popular demand, SMA connectors instead of micro U.FL connectors. Check out the comparison table below for more details.
