The Modos Paper Monitor is powered by the Caster e‑paper controller, which is built on a Xilinx […]

How to reverse engineer an analog chip: the TDA7000 FM radio receiver

Have you ever wanted to reverse engineer an analog chip from a die photo? Wanted to understand what's inside the "black box" of an integrated circuit? In this article, I explain my reverse engineering process, using the Philips TDA7000 FM radio receiver chip as an example. This chip was the first FM radio receiver on a chip.1 It was designed in 1977—an era of large transistors and a single layer of metal—so it is much easier to examine than modern chips. Nonetheless, the TDA7000 is a non-trivial chip with over 100 transistors. It includes common analog circuits such as differential amplifiers and current mirrors, along with more obscure circuits...

NV8600-Nano AI developer kit Review – Part 1: NVIDIA Jetson Orin Nano 8GB devkit unboxing and first boot

AAEON has sent me an NV8600-Nano AI developer kit equipped with an NVIDIA Jetson Orin Nano 8GB for review. I’ll start the review with an unboxing to check out the board itself and accessories, before booting it to the preinstalled Ubuntu 22.04 OS (JetPack 6.2). In the second part of the review, I’ll test the board and software in more detail, including some benchmarks and features testing with a focus on AI demos using the provided USB and Raspberry Pi cameras. NV8600-Nano AI developer kit Unboxing I received two packages: one for the NV8600-Nano AI developer kit itself, and a...

Tonybot educational humanoid robot is programmable with Arduino, Scratch, and Python

While child-sized humanoid robots like the Unitree R1 have come down in price, not everybody has a spare $6,000 to throw around to play with robots, and smaller models like the Tonybot are more affordable for educational purposes. The Tonybot offers 17 degrees of freedom, relies on high-voltage bus servos and anti-blockage servos, and has a separate ESP32 expansion board for extra modules. Optionally equipped with an ESP32-S3 AI vision camera and an AI voice integration module, the 38cm tall humanoid robot supports object and face recognition, color and line following tracking, human-robot interaction, fall recovery, obstacle avoidance, and more,...

Самодельные французские радиолампы 1920 г. Часть 3. Разрядная трубка, лампа накаливания

С любопытством в уме и почтением в сердце продолжим заглядывать через плечо французскому ламподелу-любителю 1920-х годов — М. Н. Минье, примечательного неукротимым энтузиазмом и использованием в работе простейших средств. Дела у нашего героя идут всё интереснее — обзаведясь простейшим огневым оснащением и невеликим ассортиментом материалов (Часть 1), он уже освоил ряд нехитрых стеклодувных приёмов и изловчился собрать простейший стеклянный вакуумный насос ртутно-капельного типа, для опорожнения (откачки) своих электровакуумных приборов (ЭВП) (Часть 2). Ниже — первая порция работ практических — дополнение вакуумного насоса простейшим средством измерения — разрядной трубкой; изготовление учебно-тренировочных ламп накаливания.

Домофон Лидер-М. Как скрестить трубку с ключом и всем проиграть

Приветствую всех!

Когда-то я уже рассказывал про цифровые домофоны и про то, как они работают. Но, как оказалось, их система с перемычками была далеко не единственной.

В конце девяностых появилась ещё одна схема, использовавшаяся в малораспространённых питерских домофонах. Чем она была примечательна и почему она так и не получила распространения? Сейчас и узнаем.
