    Extending the right to repair

    And it's the right to repurpose.
    Here is a good example why: https://hackaday.com/2019/07/18/put-...s-edp-adapter/

    In the aforementioned link, it shows that an Embedded DisplayPort (eDP) LCD can be connected to a standard DisplayPort output via a simple passive adaptor where EDID data is stored on the panel (and accessed via the auxiliary channel), and since I cannot find any current model tablets with a minimum 4K (3840x2160) display (and that 4K eDP panels around the 12-16 inch range are not hard to find at a reasonable price but are typically limited to a fixed set of timing parameters without using an external controller - beware, there are "4K" panels which do not have actual 4K resolution), I decided to start planning to build one with a Dell 4K touchscreen with eDP (fortunately, the camera and touchscreen are USB and therefore easy to connect (the microphone has a digital interface (no issue with picking up analog noise via the cable) can be connected via the I2S interface but it would take some guesswork to determine the data format) - if the eDP auxiliary channel instead of USB was used for these two devices (not the microphone), it would need an SBC with DisplayPort or a special adaptor which converts the auxiliary channel (480 Mbit) to USB).
    My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

    old X58 triple channel board... memtest86 memory speed?
    by eccerr0r
    Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.

    Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...

    Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any...

    Reverse engineering of 18650 4-channel tester
    by spleenharvester
    Hi friends

    I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...

    American Audio VLP1500 Distorting on one channel
    by dicky96
    Hi guys I have a VLP1500 amplifier here - one channels works fine and the other channel distorts even at low volume settings

    Protection and Clip LED are off

    There is something wrong with the BIAS voltages around T16 and T18 (in particular) on the bad channel

    I tested all diodes and transistors in this area in circuit with diode mode - both channels seem identical. Same in resistance mode across all the resistors here.

    The output DC voltages on pin1 and pin8 of the 5532D dual op amp at the input of each amplifier module are the same, and the audio...

    Hitachi V19B01922 Channel Tune problem
    by dicky96
    Hi Guys
    I have a customer who has two Hitachi TVs in his bar, one is the model in the thread title and the other is a larger screen but has the same setup menu

    He also has an LG TV, so three screens in the bar

    I installed three Satlink ST-6503 DVB-T Modulators
    This model https://www.aliexpress.com/item/32916553905.html

    These connect to three satellite receivers via HDMI cables and then connect to a 4 way RF Amp that connects to the TVs on aerial cable. There is no incoming terrestrial antenna. I set the channel ID on the modulators to...
