Did you know that CD-Online was also available for PC users? It was called Cynet Plus, and the similarity to the CD-i package is immediately noticeable.

[VGA Add-on for Philips CD-i] I wanted to mod my CD-i with RGB, but the output options always involve removing a jack or cutting an extra hole. So I decided to create this add-on to minimize case modification🤔 This will also allow dual output, which is cool!👀 GitHub: github.com/jeffqchen/CD...

I’ve finally managed to get my hands on a TecnoPlus TP521 CD-i Joystick, which is one of the rarer accessories. It’s also the only CD-i controller of its kind, as the Philips CD-i Joystick 22ER9014 was never released. A TP522 CD-i Port Splitter is included in the box.

A new home for my UV solder masks: 15 ml amber glass jars with airtight plastic lids. From the beginning, there were problems with the syringes, which often dried out or leaked from the top. Although the masks have now expired, they still cure and are too good to throw away.

First impressions of the Pioneer CD-I AUTOCHANGER COMMANDER COI-V10: CD-i PCB, A/V PCB, I/O PCB, a switching PSU and a linear PSU (transformer, power PCB, power switch PCB). Of course, these are not all of the PCBs; there must be at least three more at the front of the unit. 1/x

5 Dec 2025

Pioneer COI-V10 – two power supplies. The fuse holders on the linear PSU board were a bit loose and brittle, so I had to replace them. I also cleaned it with ColorCoral – you can really see how dirty it was from the before and after colours. 3/x

5 Dec 2025

1. Back of the linear PSU board. 2-4. The switching PSU is a Sanken SSG030-05A, whose LED flickers irregularly when switched on. For now, I am only providing photos of the inside (three different screws hold it together) and will begin analysis/repair at a later date. 4/x

4 Dec 2025

The CD-i board is original Pioneer hardware and not an evolved Kyocera board (as in the Nikkodo/BMB units). The release date is not yet known, but it must have been in the second quarter of 1996 (according to chip markings). The battery still powers an area with SRAM and RTC. 2/x

Reworked the Timekeeper with the PCB by @cabridiy.bsky.social and thoroughly cleaned and greased the tray loader. The CDM has not been touched yet, but appears to be defective. The repair is a story for another day... 5/x

25 Nov 2025

Replaced the laser sledge and cleaned and greased the CDM. The focus error is now gone and the discs are reading perfectly again. As a finishing touch, I added a drop of UV lacquer to the spindle. 6/6

On closer inspection, the Grundig CDI 110E mainboard appears to have been converted from a Mono IV NTSC mainboard with an RF modulator. The soldering is somewhat rough. 3/x

Cleaning up the rework, removing the Timekeeper and installing a new socket (and cleaning up again). 4/x

It didn't come with a DVC, but with something much better: a DVC eject mechanism that I've never seen before. 2/2
