Spare TV Box Board Sold for MXQ-4Q / MXQPro DIY Repairs

Spare TV Box board

Once somebody asked me if spare TV box boards were available for purchase since his TV box died after a few months, and he wanted to repair it himself without having to purchase another complete TV box. Usually, such boards are not sold, except maybe on Alibaba, where you may or may not have to purchase in quantities. So I basically told him it would be hard to find, and buying a new or second hand TV box would be a better option. But I was recently made aware that at least one seller was offering spare TV box boards for MXQ-4Q and MXQPro on Aliexpress for $20.61 shipped in order to let people repair their boxes themselves. If your goal is to repair a TV box, I can only think of two reasons for buying a spare TV box board: saving money and/or reducing electronics waste. MXQ-4Q and MXQPro […]

Haven Open Source App Transforms Your Old Android Smartphone into a Smart Security Camera

About two years ago, I wrote a post asking what to do with old devices instead of throwing them away. My own proposals included giving them away, reselling them on eBay, recycling them for other purpose like servers or download clients, or scavenging some parts. Other people also comments what they did with theirs, for example setting up a Linux cluster with old TV boxes. Another way to recycling an old (Android) smartphone – albeit you could always buy an inexpensive one – is to install and run Haven, an open source app that transforms your phone into some sort of smart security camera, but instead of only using the camera from the phone, the app also logs audio events using its microphone (array), as well as data reported by sensors. One of you first reaction might be: “cool! somebody may an app that would allow hackers or government to […]

Convert an old ATX Power Supply into a Bench Power Supply with (or without) 3D Printed Parts

You may own one or more old computer towers with an ATX power supply that just gather dust, but since the ATX connector provides +12V, -12V, 5V, 3.3V and GND signal it could be converted into an bench power supply. People have been doing this for a while, but elliotboney’s solution looks neater than most with a 3D printed part that’s attached on top of the power supply. Once you have printed the part, which may need to be adapted to to your power supply, you just need a few banana jacks, and a power switch before connecting with the cables: I basically kept 3 wires of each voltage, a 3 black wires for each ground. So 3 yellow for 12V, 3 Red for 5V and 3 Orange for 3V. Any extra wires I cut as close to the board as possible and put a little piece of heat shrink […]

Connect a 9.7″ Retina Display (iPAD 3/4) to Your Computer via a DisplayPort Adapter

One way to connect an extra Retina (2048×1536) display to your computer is to purchase Adafruit Qualia 9.7″ DisplayPort Monitor for $224.95. But in case your budget is limited, you could combine an old iPAD 3/4 display with AbuseMark 2048×1536 LCD to DisplayPort Adapter for 3,500 JPY ($29 US). If you don’t have an old iPAD, or would rather not dismantle your “old”-but-still-useful iPAD, you could purchase LG LP097QX1-SPC1/2, LG LP097QX1-SPA1/2/V, or Samsung LTL097QL01-W01 LCD panels instead for about $80 on Amazon US (LP097QX1 / LTL097QL01). If you live in Japan, AbuseMark also ships a complete kit for 12,000 JPY.   Key features listed for the board: Video Input – DisplayPort Display Connector – 51-pin 0.3mm pitch FPC connector STM32F103CB 32-bit Cortex M3 MCU with native USB for firmware update and power/brightness/etc control Dual TI TPS61187 WLED drivers Power – USB or 5V-powered (separate connector) / 1.35A total current draw.

What Do You Do with Your Old Devices and Boards?

New and faster processors and products come out regularly, and prices have come down so much that people are likely to discard old devices, or let them collect dust, as new devices can be bought for half the price you bought your now sluggish single or dual core mini PC, remember CX-01?, last year or two. However, people may not like to through perfectly usable product by principle, while others may be concerned by the pollution effects of our consumerism, and craze for the latest gadgets. There must surely things that can be done instead of simply trashing old devices. I’ll give some ideas mostly for mini PCs, but since a group of person is smarter than one only, I’m sure I get some interesting input. Give your old devices to friends of family.
