The title of that post may look crazy at first, but it’s not, it is entirely possible to convert your cheap 100M 8 port switch or stuff like that to a managed switch. That’s possible simply because, if you open up one of these and look at the datasheet, you will find out that they … Read moreConvert your cheap “unmanaged” switch to a VLAN capable layer 2 managed switch for just $2
When you buy an 898D soldering station there’s a very high chance that it is completely uncalibrated, leading to burnt/damaged parts and other kinds of problems since most of the times it is calibrated to give much higher temperature. For that procedure you are going to need: A cross-head screwdriver to open the 898D A … Read moreCalibrating YIHUA 898D soldering station
You should have noticed that most multimeters come with a function to test BJT transistors, but none has a function to test the today’s more common MOSFETs Here are the steps to test an N-CHANNEL mosfet with just a multimeter ( applies to P-CHANNEL too, just swap + and – ), of course the MOSFET has … Read moreHow to easily test an N-CHANNEL or P-CHANNEL MOSFET using just a multimeter
The SITECOM WL-326 is an ethernet+3g router featuring 300 Mbps wireless and an usb port to connect a 3G modem. This device is not officially supported by OpenWRT and not very common, so there’s basically zero info on it at the moment. First thing is to find out which SoC it uses, since it is … Read moreInstalling OpenWRT on SITECOM WL-326
You may have heard of SVP project , if not visit their website http://www.svp-team.com/ . SVP in a first pass calculates the motion vectors for the frame ( the direction and velocity that every object in the video has moved with ), and then on the second pass it generates intermediate frames. With that technique it can … Read moreConverting movies to 60 fps on linux ( with wine )
In these days i’ve worked on how to create a system that allows me to turn on and off lights or appliances at home with minimal cost and complexity, and there it is: https://github.com/tizbac/IoTManager Each node (ESP-01 ESP8266) with nodemcu firmware and the init.lua script from esp8266 folder of my repository has two outputs and can … Read moreA very simple internet of things system to control lights and other stuff

What you need An access point running OpenWRT and supporting 4 address mode ( WDS ) Another access point running OpenWRT and supporting both multi-ssid and 4 address mode ( or only 4 address mode if you want wifi->ethernet bridge ) Setting up the main access point First of all , you need to setup … Read moreHow to do transparent bridging / repeater on OpenWRT with an Atheros card
These months there has been a lot of work on reclocking support for NVA3 nvidia cards by Roy Spliet on the opensource nouveau drivers. Since i own a Geforce 210 GT i’ve decided to give it a try with some benchmark and the results are quite good The reclocking of these cards is still very … Read moreQuick test of NVA3 series reclocking with nouveau and comparison with NVIDIA drivers
In these days between some exercises for a microeconomics exam , i’ve continued to work on reverse engineering the Alcor 698x UFD microcontroller, and i’ve got another poor quality Alcor based flash drive from a friend , so now i’ve an 8 GB one , and a 4 GB one. I’ve started , with the … Read moreAlcor UFD Controller Hacking update 2
