STM32CubeMX GCC Makefile project

Baoshi writes: Writing peripheral initialization code is probably the most tedious work in embedded development. It always successfully stops me from starting a new project. I believe engineers at STMicroelectronics share the same pain. Therefore they created STM32Cube firmware and STM32CubeMX graphical configuration tool, which turns numerous key strokes and page flips into just a […]

PC storage oscilloscope and logic analyzer

From the comments on our earlier USB oscilloscope with signal generator post, here’s a PC storage oscilloscope and logic analyzer by Nerd Ralph: A logic analyzer is a useful tool when working with micro-controllers, but when compared to the price of Arduino compatible boards, they are expensive. While the ability to decode different protocols is a […]

Ultra Librarian and Eagle tutorial

Luca Dentella writes: Ultra Librarian is a tool by Accelerated Designs to manage libraries of eletronic components (CAD design, simulation, 3d-modelling…). Many IC manufacturers provide Ultra Librarian files (.bxl) for their products: this tutorial will show how to use those files in Eagle… Via the contact form.

PCB a Week 9: MrRef voltage and current reference update

Mats posted pictures of his MrRef voltage and current reference PCB build.  This tool helps check the accuracy of your multimeter: Since my Agilent 34401 is currently out of calibration I didn’t bother installing the fine-adjustment trimopot. The 6350 is good for 0.02% (1mV) without any adjustments. But I installed two 10K 0.05% resistors on the […]

PCB a Week 9: MrRef voltage and current reference

Mats continues his challenge of designing one PCB every week. This tool helps check the accuracy of your multimeter: The design might be interesting anyways since it has remote sensing for compensating for voltage drop in the cables. But if your meter is drawing enough current to cause more than a 1 mV drop you […]

PCB a Week 8: NU-FitHole hole size helper

Mats continues his challenge of designing one PCB every week.  This tool helps to determine exact hole dimensions for screws and other parts. This weeks PAW will be extremely simple – it’s not even a breakout board, but it might still come in handy for people making PCBs. The FitHole is a tool for testing […]

High speed passive component pick and place machine for $3600

Mats tipped us to this high speed pick and place machine that’s currently about $3600 on Taobao. It features 15 automatic reel feeders, and the top speed of the machine is 6000 parts per hour. The placement head can handle parts as small as 0402, but it doesn’t use a vision system so accuracy will […]

Guest Review: Chipquik smd291nl no-clean tack flux

Sheldon has been using the Chipquik SMD291NL no clean tack flux, here is his review of it: Very tacky, can hold qfn and dfn by itself, once heated it  becomes very sticky and is hard to clean even with 91% ipa. It works great though, have not had any problems with it not wicking solder […]

Guest review: Atten PPS3203T 3 channel 3A programmable power supply

JuKu wrote about his latest purchase, the Atten PPS3203T 3 channel 3A programmable power supply. It features 2 0-32v channels and a single 0-6V channel, as well asRS-232 and GPIB (IEEE 488.2) interfaces. I wanted an economical three output power supply (+- 15V or so for analog, 5V or 3.3V for digital) with voltage and […]

Measuring power with INA219 and an MSP430 Launchpad

INA219 is a cool IC that measures voltage and current trough a shunt resistor, and relays the information over I2C. It provides the multiple of the two values, thus enabling easy power measurement. Opossum used it along with a Nokia 5110 LCD and a MSP430 LaunchPad to build a nice power-meter. Via 43-oh.
