Hak8or got his hand on an X-ray bone mineral density assessment machine someone dumped. It seems the only problem is a faulty temperature sensor, but Hak80r decided to break it down and share the pictures with us. For an in-depth … Read more
Kenneth scored two HP universal frequency counters and popped them open. One generates the timebase from an uncompensated oscillator in a TO-5 package, while the other uses a large temperature controlled oven oscillator: here is both of my counters measuring … Read more
Mick bought and disassembled a Tektronix 465 oscilloscope. It’s a 100 MHz dual trace, dual timebase analog scope. He points out that most of the transistors are socketed instead of soldered. More pics below. Via the forum.
Philip scored a vintage Sanyo 4 function calculator in a local thrift store. He opened it up and was pleasantly surprised with 8 Nixie tubes. You guys wont believe what i just scored from a local thrift store [selling second/third/fourth … Read more
Raj has been designing a soldering station that would support Weller’s RT type tips with temperature sensor and heater built into them. A stereo-type jack on the iron connects them to the soldering station cable. So far Raj has reverse … Read more
Schazamp bought a cheap Kendal 852D+ 2+1 hot-air and soldering iron rework tool. He opened it up and took some pictures. Most of the 852-whatever clones look pretty similar inside, there’s probably one factory churning out clones under a bunch … Read more
Weller WSM 1 is a 40w soldering station that drives WRMP soldering pencils with RT type tips. Inside you’ll find an LCD, a few ICs, and a few discrete components. It’s powered by a laptop power supply, and that the heater … Read more
Hak8or got his hands on a few broken down TVs. One of which is a Dell W3000 set. It’s panel was intact so he figured it was worth to try and fix. After some probing he figured out there was … Read more
EETimes has posted their video of the teardown of the Azio USB 3.0 3.5″ HDD enclosure, one of the first devices using USB 3.0 (4 Gb/sec.), with a street price of about $25 USD.
Hotsolder repaired his malfunctioning Rigol, A bad rotary encoder can make your tools useless in worst cases. Fortunately it is an easy fix, he has created a slide show demonstrating just how easy it is. Via Hack a Day
Any car newer than 1995 has a fairly sophisticated computer used to monitor various systems ranging from accelerator pedal position to catalyst efficiency. This is a brief introduction to one example of the hardware used to diagnose automotive systems.
Here are some examples by manekinen of what can happen when an apparently high reverse voltage is applied to several AVRs. Via Hack a Day.
Here’s another cool tech video by Jeri Ellsworth, this time illustrating how speed radar works using parts from a toy radar gun. Also refers to similarly using a satellite TV LNB module.
The Zeno is an acne treatment device with disposable tips that are electronically limited to 45 or 60 uses. Matt did a system teardown that revealed a Cypress cy8c27443 microcontroller in the main unit and a 128byte I2C EEPROM in … Read more
Today we have teardown photos of a Sure Electronics PICkit2 clone PIC programmer, the type commonly sold on eBay. Scopria, who took these pictures, reports that his programmer stopped working after a few months. He recommends a real Microchip PICkit2 … Read more
PICkit2 is a programmer for Microchip PIC microcontrollers. It has limited debugging features and a low-speed serial protocol analyzer. It’s really useful for low-volume production programming because it can store firmware and program circuits while not attached to a PC. … Read more
