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 TV boxes are already cheap devices based on Rockchip RK3229 …

How to Make a Low Cost DIY SD Card Duplicator

If you have to duplicate many SD cards for example to boot Raspbian on multiple Raspberry Pi board, one option is buy one of those SD card duplicators, but the problem is that they are not really cheap, for example the Systor 1-to-7 cards model sells for $540. Bob Brown, a retired senior lecturer, is now teaching K-12 students how to get started with Raspberry Pi boards, and must prepare bootable SD cards for his class. In order to save time, a duplicator would have been nice, but the price is too high, so instead he went with a DIY solution. You’ll first need some hardware, including a powered USB hub with the number of cards you want to duplicate, and corresponding SD card reader, and a larger micro SD card to hold Raspbian and/or other operating systems (optional, only for Raspberry Pi based duplicator). Mr. Brown made a 10-port SD card duplicator (1-to-9) for just under $100. One the …
