PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost […]

PORTLAND, Ore.–Purdue University researchers have demonstrated a CMOS-compatible all-optical transistor capable of 4THz speeds, potentially over a 1000 times faster than silicon transistors. Nano-photonic transistors processed at low-temperatures can be fabricated atop complementary metal oxide semiconductors (CMOS) to boost switching time by ~5,000-times less than 300 femtoseconds (fs) or almost 4 terahertz (THz), according to […]

WinHeist Windows Hobbyist Electronic Inventory SysTem WinHeist is an electronics component organizer that was developed by a programmer with an electronic habit. It has developed over the years from a personal application used by the author into the full blown application that it is today. To get a look at WinHeist and get an idea […]

Atmels AVR ATtiny10 are surprisingly powerful devices that come in an extremely tiny SOT23 package with only 6 pins. The have 1kb of flash, 32 bytes of SRAM and use the reduced AVR core which only supports 16 instead of 32 register. It seems like Atmels idea of these devices is to use them as […]

Vibrobots (and bristlebots) are simple robots that use a tiny pager / cellphone vibrator motor (with an eccentric weight) to randomly bounce around — they are the subject of many Maker / DIY projects as well as some well-known commercial toys (such as the $7.00 Hexbug Nano).  Naghi Sotoudeh, a Hizook reader from Iran, contacted […]

Extremely cheap low-speed PC/USB oscilloscope with STM32 (STM32F042) microcontroller – variant of miniscope v2e with input amplifier (MCP6S21 PGA) added. This is minor update, but input PGA fixes problem with input leakage of STM32F042 allowing increasing input impedance at the same time. Quick specification follows miniscope v2a-d idea: very simple device streaming data in real […]

We wrote this whole page to try to make buyers of USBasp programmer clones aware of what’s possibly out there for sale and the conclusion we came to about the units we bought, after quite some investigative work IT SIMPLY DOES NOT REALLY WORK !!! We tried to read the flash content, and the blue led […]

Cree’s CGHV14500 is a gallium-nitride (GaN) high-electron-mobility transistor (HEMT) designed specifically with high efficiency, high gain and wide bandwidth capabilities, which makes the CGHV14500 ideal for 1.2 – 1.4-GHz L-Band radar-amplifier applications. The transistor could be utilized for band-specific applications ranging from UHF through 1800 MHz. The package options are ceramic/metal flange and pill package. – […]

These modules come in different shapes and colours and can be purchased from the internet for 3 dollars only. They are therefore cheap enough to enable many Internet of Things applications like monitoring your home temperature and activity all year round (if you ever need to do that). And at this price, you’re actually better […]
