Tesmo Kickstand: Truly invisible laptop stand that weighs nothing and takes up zero space

Posted on 30 August, 201913 September, 2019 by Emmanuel Odunlade

Tesmo, a company dedicated to innovation and excellence, announces the launch of its laptop stand; The Tesmo Kickstand in September.

The Kickstand is an ultra-slim, portable and ergonomic laptop stand which can be used with any laptop type can be gently attached to your laptop to instantly transform it into an ergonomic and comfortable workstation wherever you are. Speaking about the ideologies behind it, Mark Lin, Head of Product Design at Tesmo said;

“We all appreciate the freedom of working on a laptop; it’s easy to stay productive whether you’re at your desk. But when it comes to ergonomics, a laptop isn’t the greatest choice since you can’t adjust the height of the keyboard and screen separately. Most of the laptop stands on the market are heavy and bulky, Tesmo is constructed with a clever structural which instantly enhances the comfort of typing. With a lightweight and portable design, it can be used anywhere, anytime.”

The Tesmo Kickstand perfectly demonstrates the design philosophy of slim, compact and efficient with two tiny adhesive pads stay invisible when laid flat to blend in with your laptop. The compact nature of the pads design enables air to flow properly through the air vent of your laptop and its integrable design nature allows you to attach the pads to any corner of the laptop thereby fitting almost all laptop models.

Convenient to carry and adjustable on different surfaces. While the Tesmo Kickstand has a thickness of only 4.5mm and weighs just 17g/0.6 ounces, the unique triangular load-bearing structure of the kickstand allows it to hold up to 17.6lbs in weight. This means the kickstand could also support your slightly heavy laptops.

The Tesmo Kickstand uses a special, strong removable glue which lets it be attached and detached from your computer with ease and without leaving a scratch on the computer. The adhesive ensures the kickstand can be used multiple times with the adhesive remaining as strong as always. Whether in the office, at home, or in a café, Tesmo Kickstand will always provide you with the convenience of a portable laptop stand plus ergonomic comfort and its seamless integration with your laptop will ensure you are never troubled by forgetting to take a laptop stand when going out.

The highlight features of the Tesmo Kickstand includes;

lightweight & easy to use, no need to carry it alone, ideal for a mobile office
One size fits all: Applicable to almost all laptops on the market, comes with unique design won’t block the vent of your laptop
Strong Adhesive: Attach and detach without leaving a single mark
Move freely and enjoy ergonomic comfort anywhere

The Tesmo kickstand is currently only available in grey and will land on Kickstarter in September. During crowdfunding, users can get it for US$15 (MSRP US$29). Customers can also pre-order with their email address on Tesmo’s website with delivery expected to be in October.

Update 13/09/2019: The campaign is live on Kickstarter and has 27 days to go with pledges starting at $15.

Ant USB-C LiPo Charger on Tindie

Posted on 30 August, 201930 August, 2019 by mixos

The USB-C has been around for quite a while, but there is still a lack of a miniature basic USB-C chargers for LiPo battery. I decided to make my own with as minimal footprint as possible, which resulted in being 13.5mm x 16mm.

A well known MCP73831T-2ATI/MC is used as a battery charger in DFN package, to minimize the risk of thermal throttling. A high quality USB-C connector is used from Amphenol (12401610E4#2A). The charging current is configured to 500mA. Battery wires are soldered directly to the board by a user. Two LEDs indicate whether a battery is charging or is charged.

The mounting cutouts are designed for M2.5 or M3 size screws.

Fujitsu Semiconductor Releases World’s Largest Density 8Mbit ReRAM Product from September

Posted on 29 August, 201928 August, 2019 by mixos

Featuring memory with the industry’s smallest read current, optimal for small wearable devices

Fujitsu Semiconductor announced the release of the 8 Mbit ReRAM MB85AS8MT, which has the world’s largest density as a mass-produced ReRAM product, available from September 2019. This ReRAM product was jointly developed with Panasonic Semiconductor Solutions Co..

The MB85AS8MT is an EEPROM-compatible non-volatile memory with SPI-interface that operates with a wide range of power supply voltages from 1.6 V to 3.6 V. One major feature of this memory is an extremely small average current for read operations of 0.15 mA at an operating frequency of 5 MHz. This enables minimal battery consumption when mounted in battery-operated applications with frequent data-read operations.

Since it can be provided in a very small WL-CSP (Wafer Level Chip Size Package), it is optimal for battery-operated small wearable devices such as hearing aids, smart watches, and smart band.

Fujitsu Semiconductor offers various Ferroelectric RAM (FRAM) products featuring higher write endurance and faster write speeds compared to EEPROM and flash memory. Our FRAM products are becoming known as the optimal non-volatile memory for very frequent data logging and for writing data protection against sudden power outages. Meanwhile, some customers have been requesting memory that uses less current for read operations because their applications perform operations with small data write counts and very frequent data reading.

In order to meet such needs, this new non-volatile ReRAM memory has been developed with the two features of “large density enabling byte-access” and “small read current.” This time, our company has newly developed the MB85AS8MT, featuring world-class largest density in the ReRAM family at 8 Mbit. Its electric specifications, such as commands and timings, are compatible with EEPROM products.

Therefore, mounted in battery-operated applications with frequent data-read operations, such as specific program reading or setting data reading, it enables minimal battery consumption due to its very small read current.

The package is an EEPROM-compatible 8-pin small outline package (SOP). In addition, a very small 11-pin WL-CSP package of 2 mm × 3 mm is available for mounting in small wearable devices.

Key Specifications

Memory density (configuration): 8 Mbit (1M words × 8 bits)
Interface: Serial Peripheral Interface (SPI)
Operating power supply voltage: 1.6 V–3.6 V
Operating frequency: Maximum 10 MHz
Low кead operating current: 0.15 mA (average value at 5 MHz)
Write cycle time: 10 ms
Page size: 256 bytes
Guaranteed write cycles: 1 million cycles
Guaranteed read cycles: Unlimited
Data retention: 10 years (up to 85 °C)
Package: 11-pin WL-CSP, 8-pin SOP

Intelligent power module reduces power and noise for drives

Posted on 29 August, 201928 August, 2019 by mixos

Mitsubishi Electric has released a new high-performance intelligent power module (IPM), the Super mini DIPIPM Ver.7, featuring reduced radiation noise and low power consumption for the inverter drive systems of air conditioners and other small-capacity motor drives.

The device features a built-in low-noise seventh-generation insulated gate bipolar transistor (IGBT) with a CSTBT structure to reduce radiation noise while still maintaining the low-power consumption level of the Super mini DIPIPM Ver.6.

Module case operation temperature has been raised from 100 to 125ºC and maximum junction temperature has been raised from 150 to 175ºC to expand the heat-dissipation design flexibility of inverter systems. The 24.0×38.0×3.5mm package has a 40A current and is pin compatible with conventional Super mini DIPIPM series.
