ChipWhisperer-Husky is a compact package for experimental side-channel power analysis and fault injection. It follows in the footsteps of our ChipWhisperer-Lite and ChipWhisperer-Pro products and adds new features such as a high-speed logic analyzer for visualizing faults, real-time data streaming for attacking asymmetric algorithms, and additional I/O Extension pins.
ThunderScope is the first oscilloscope designed specifically for Thunderbolt, allowing live sample data to be streamed to your computer at over 1 GB/s. This design eliminates all limitations of traditional oscilloscopes by leveraging the powerful processing capabilities of modern devices. Measurements are made fast and easy, with cramped UIs replaced by multi-window layouts and support for modern accessibility features. Sample memory was increased from megabytes to gigabytes, and the fixed list of protocols and trigger types was replaced by an ever-expanding repo. ThunderScope is also open source, so you have complete control over your data from the moment you sample it. You can easily add your own custom features and benefit from new features built by the community.
PlainDAQ is a simple, useful tool that adds basic precision analog functionality to your Raspberry Pi Pico board. It features a precision, low noise, low drift 12-bit 500k sps/s ADC. To match the ADC and maintain its noise and accuracy, all analog inputs are buffered and the ADC is driven by a high speed/low noise fully differential amplifier. It also has a 10-bit DAC that helps create analog outputs and waveforms.
AquaPing is an ultra-low power smart sensor that provides isolated water leak detection, even behind walls.
BeanCounter is a pocket-friendly SMT parts counter. Powered by a CR2032 coin cell battery, it uses two infrared photointerrupters to count parts as quickly as possible. It works with any opaque, 8 mm wide carrier tape up to 2 mm, and it covers most 0805 or smaller LEDs and passives, as well as SOT23 transistors.
Although Geiger counters can be used to detect amounts of radiation, and with some tricks can also differentiate between the three types of radiation (alpha, beta, and gamma), their use is limited in identifying radioactive materials. For this purpose, gamma-ray spectrometers come in handy.
The basic concept of this work is slightly different from standard tools such as a reflow oven or soldering iron. Heat is provided from the bottom of the PCB.
A practical heating table for PCB reflow soldering. It is quite cool. It may be the most beautiful and functional heating table on the market. Parameters: The hardware is based on the ESP32PICO-D4 chip, the input power is 24V/10A, the maximum power is 200W, and the heating temperature is up to 300°C. It has Bluetooth function. If I have time later, I will develop a mobile APP to set the temperature rise curve.
The author noticed that the AC line frequency changes in spans of 0.4 Hz and periods of several minutes, so I wanted to examine long-term changes in AC line frequency and voltage. This is a project to build a line voltage frequency monitor. It is not a complete instrument but a simple measurement adapter designed to be embedded in some measurement system with a PC or microcontroller.
During the dry season we often get electrocuted by metal objects, especially door handles. This is due to the charged static electricity in the human body. Any object can be charged, and often objects have electrical potentials of several thousand volts or more. Static electricity often causes malfunction or damage to electronic equipment. I've always wanted to know how much static electricity is carried in an object or human body, so I made a surface potentiometer to measure the potential of a charged object.
Flipper Zero is a portable multi-tool designed for developers and geeks with a toy-like body. It enjoys exploring digital content such as radio protocols, access control systems, hardware, and more. It's completely open source and customizable, so you can extend it in any way you like.
High reference value, the 50-year-old work of FatFS author ChaN
A phase compensation algorithm is used to compensate for the additional phase delay introduced by the multiplexed ADC, thereby producing an effect equivalent to a synchronously sampled ADC.
ESP32s2 Thermal Imager=ESP32s2 + Lepton 3.5 + Battery charger + 240x240 pixel LCD
The goal of PSLab is to create an open source hardware device (with all resources fully open) that can be used by electronics enthusiasts to do experiments. And offers a range of sensors for engineering experiments, including oscilloscopes, waveform generators, frequency counters, programmable voltage, current sources and data loggers.
The MAXREFDES1219 is an integrated smart solution for the 1-cell Li+ battery pack that provides a linear charger
Supports various Cortex-M cores, can be used wirelessly in the local area network, and can be used remotely in the external network.
The author opens up the schematic diagram and supporting Raspberry Pi code. The simulation bandwidth is already 30MHz, and the frequency response is very close to the theoretical simulation, with a difference of about 0.02dB between 1kHz and 30MHz.
