Hosts Dave Jones and Chris Gamble discuss the open-source RC controller from Gizmo For You, highlighting its complex injection-molded cases and 8-layer PCB. They review Ken Lumbard's 'Reading Jim Williams' project, which curates and analyzes the application notes of legendary analog engineer Jim Williams. The hosts also cover rumors of a DARPA humanoid robot grand challenge and share experiences using CircuitLab for SPICE simulation.
Hosts Dave Jones and Chris Gammell discuss the community excitement surrounding the 555 timer contest, with Jones sharing his experience using a vintage 1976 Signetics triple 555 chip. The conversation shifts to industry news, including Intel's $700 million loss due to a chipset bug, National Instruments' R&D hiring plans, and the business models behind free EDA tools from Analog Devices and Microchip. The episode also features a 'Workbench of the Week' segment showcasing hobbyist setups and a discussion on the viability of plastic transistors and laser PCB cutting.
Hosts Jen Castillo and Alvaro Prieto discuss their pandemic-era projects, including Alvaro's recreation of his father's 7400-series digital clock, a USB-C power adapter using a Cypress chip, and a t-shirt quilt. Jen details her reverse engineering of a greeting card chip, her exploration of Chinese manufacturing via Alibaba, and her choreography of a remote dance piece. They also cover the cancellation of hardware conferences like Hackaday Supercon and HackRF, and recommend movies such as 'Mood Indigo' and '3 Idiots'.
Dave Jones of EEVblog and Chris Gammell of Contextual Electronics discuss their upcoming in-person meeting in Australia and New Zealand, highlighting plans for maker meetups and tech tours. Jones details his firmware hack of the Keysight 1000X-Series oscilloscope to unlock higher bandwidth and sample rates, while also noting a footprint error in his Mixy Tube clock project. The conversation shifts to industry news, including the CIA's Vault 7 leaks, the use of silicon carbide electronics for Venus landers, and the security risks of IoT devices like the Cloud Pet teddy bear.
Hosts Chris Gammell and Dave Jones discuss a variety of hardware engineering topics, starting with Jones's experience of a transformer failure in a Weller soldering iron due to a non-fused primary side. They then explore the new LoRa SIP from Microchip, which integrates a Cortex-M0+ and radio, and Microsemi's Polar Fire FPGAs with RISC-V cores. The conversation shifts to the ethics of scavenging electric scooters, the challenges of using a Neoden pick-and-place machine for small batches, and the planning for an upcoming KiCad layout contest.
