@hiroshi07779831 look, this was my cleaning process! Some disk cases had the Felton dead too, but the mold was cleaned easily with soap!

Now, trying to read some old floppy disks(full of mold). The protective fabric inside the case on some of them is also rotten. At least I got how to read some of these almost dead disks: change the case, clean the disk surface with very soft fabric + soup, and clean drive heads

@hiroshi07779831 Be careful using mold disks as the mold stick to heads and scracthes the disk. I openes my ones and literally gentle washed with a cloth and dish soap to remore the mold. It workek perfecly!

アイワのメガCDラジカセ「CSD-GM1」です。メガドラ部分のメイン基板はこんな感じになってるんですねー。メガドラはこういう派生系がすごく多くてマニア魂が燃えます。　（天元中）

My PS3 lost ability to produce HDMI output. The IC was in short. Removal of old one with success. Let's test my ability to resolder a new one without proper tools 😅

@RueNahcMohr This from the same website. I tested in past with a bf245. It works pretty nice! It's worth testing You need to rectify the output. Use fasT diodes or germanium ones. Modern implementations use a IC to do the dc conversion with a perfect usage of the wave, without the cut of dio

@RueNahcMohr you can find this on the website dicks-website.eu/fetosc/enindex… it's pretty crazy that with less than .1v you can produce higher voltages

@gordoslair This specific model is prone to die. The motor driver stop working and catch fire. I had 2 that die and I had to look around eBay to buy other ones to save the disk content!
