PRODUCT SHOWCASE Weller introduces a new range of soldering irons The leader in soldering equipment worldwide, Weller, has announced the launch of the Weller Red range of soldering irons. These are designed for passionate DIYers and craft creators, who need precision tools to make their visions come to life. Whether repairing RC aircraft or cars, general electronics, drone modifications and more, Weller soldering irons finish jobs quickly and safely. Weller’s latest sol­der­ing tech­nol­ogy, with its ergonomic handles, lighting ability and precision design, en­ables working better over longer periods. The Weller Red range comes in 25W, 40W and 80W versions, ensuring you have the perfect tool for your project, no matter the complexity. The new range also features the lat- est heat-resistant LED technology, delivering unparalleled lighting while working. An aesthetically pleasing, slimline triangular front housing captures the light and focuses it on your work area. Once the tip position is determined, the hand naturally gravitates to the triangular area, providing a stable and effective way to control the tip. Weller high-performance consumer soldering irons deliver comfort and flexibility. A round, soft grip, nonslip handle design helps relax the hand during extended use. The round handle provides a mechanism to roll and position the tip as required. The heat-resistant housing ensures a long life, and the high-performance stainless steel heaters ensure quality soldering for years to come. The Weller Red range features temperature control up to 470°C (model dependent), allowing soldering for myriad DIY and craft applications. Weller soldering irons can be purchased from Bunnings Warehouse; see siliconchip.com.au/link/ab81 Weller Tools www.weller-tools.com Mouser now stocking ams AS7038xB and AS7030B vital sign sensors Mouser is now stocking AS7038xB vital sign sensors and the AS7030B sensor module from ams. These small sensors are suitable for medical wearables and remote diagnostic equipment, such as disposable patches used for blood oxygen saturation (SpO2) and electrocardiogram (ECG) measurements. The ams AS7038RB/GB sensors and AS7030B sensor module are based on photoplethysmography (PPG) and ECG. The AS7038RB sensor is the industry’s thinnest dedicated sensor for SpO2 measurement, at just 3.7 × 3.1 × 0.65mm. Mouser Electronics Inc. Phone: (852) 3756 4700 Web: www.mouser.com The sensor enables designers to incorporate vital monitoring capability into small consumer products such as earbuds, smart watches and wristbands, as well as in medical devices such as oximeters. The sensor’s on-wafer interference filter technology developed by ams enables it to capture optical signals in the 590nm-710nm and near infrared (800nm-1050nm) wavelength bands for SpO2 measurement, while blocking interference from ambient light at other wavelengths. The AS7038GB version features peak sensitivity at the 525nm (green) wavelength for use in heart rate and heart rate variability measurement, while the AS7030B HRM/HRV sensor module integrates two 535nm LEDs in a single 3.55 × 6.2 × 1mm package.
