Linux Gizmos ☛ Open-Source Oscilloscope with 1 GS/s High-Speed Data Streaming and Flexible Measurement Capabilities
Crowd Supply recently launched a campaign for ThunderScope, an oscilloscope that combines powerful hardware with open-source software. It captures data at 1 GS/s and streams it to a computer via Thunderbolt, USB4, or PCI Express for real-time processing, offering greater flexibility for complex measurements across various timescales.

Arduino ☛ Transform trash into treasure with the DIY Bottle Plotter
Manufacturers put a lot of effort into their packaging (there is an entire engineering discipline just for that) and some of it can be quite beautiful. But it usually still ends up in the landfill or, at best, in a recycling center.

Hackaday ☛ Raspberry Pi RP2350-E9 Erratum Redefined As Input Mode Leakage Current
Although initially defined as an issue with GPIO inputs when configured with the internal pull-downs enabled, erratum RP2350-E9 has recently been redefined in the datasheet (page 1341) as a case of increased leakage current. As it is now understood since we previously reported, the issue occurs when a GPIO (0 – 47) is configured as input, the input buffer is enabled, and the pad voltage is somewhere between logic LOW and HIGH. In that case leakage current can be as high as 120 µA with IOVDD = 3.3 V. This leakage current is too much for the internal pull-up to overcome, ergo the need for an external pull-down: 8.2 kΩ or less, per the erratum. Disabling the input buffer will stop the leakage current, but reading the input requires re-enabling the buffer.

CNX Software ☛ LiteWing DIY ESP32 drone costs about $12 to make
Circuit Digest’s LiteWing is a low-cost DIY drone controlled by an ESP32 module, based on a custom PCB and off-the-shelf parts that costs around 1000 Rupees to make, or $12 at today’s exchange rate. The DIY ESP32 drone was designed as a low-cost alternative to more expensive DIY drones that typically cost close to $70. The result is a WiFi drone that fits in the palm and controlled over WiFi using a smartphone. Interestingly it does not include any 3D printed parts as the PCB forms the chassis of the device.
