@RavenKwok Cool demos! Does you participate on demo scene events? What do you use for coding ? unity? c and opengl/direct x? 😁

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）

@RetroV2024 It is the ps3 super slim 😁 forgot to mention!

[h @hernandi]

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 😅

[h @hernandi]

Someone knowns where is little metal part goes inside the ps3? Is the only part I don't remember where to put 😅

[h @hernandi]

And it worked!!!!! HMDI functional again. Only problem is my hdmi cable is too big and as inducing noise. The short one works perctly, but has only 30 cm

[h @hernandi]

After careful inspection, only 4 pins were lose. Everything clean, no shorts, let's reassemble everything and test!

[h @hernandi]

Half gone, only 2 short pins.... let's keep going!!!!!

@TerminalRootTV Esse é o pai dos amplificadores operacionais. Varios designs de cis foram feitos por ele nessa mesa.

@kamet93 Wow, amazing drum! Imagine the resources to align all those heads! Could you share with us where this drum full of heads was used on?

[h @hernandi]

@kdenki What a nice and clean waveform!

[h @hernandi]

@Ethy1ene_L Cool!!! Where did you find good heads for these drives?

[h @hernandi]

@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

[h @hernandi]

@RueNahcMohr you can find this on the website https://t.co/hMNBvtTg3o 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!

@geerlingguy I would suggest that this could even be a microchip pic. Take a look in their 12f series, there are 6 pin options available!

[h @hernandi]

@int_16h I think could be possible to replicate that via SDR and some (or a lot) of code :)

[h @hernandi]

@int_16h I remember finding out this page in the later days(2000 something)! That is a marvell being done via discrete parts and ttl! The input try to do a very narrow band filtering to avoid a lot the noises. From the 1 bit adc to the processing that was light into mt eyes!!!!
