Not sure if this is the right subreddit but I think you'd like this.
![]() | Spent a couple hours today getting the silicon die out from one of these epoxied on chips. Using a small alcohol lamp. Sadly, I got some of the super glue I was using to mount it to a slide on it. [link] [comments] |

Inside a 7 pin Micro USB connector from Samsung devices (+ pinout)
![]() | I was interested to know why a usually 5pin connector plugged to a 5 wires cable had 7 pins. So I took an old connector and opened it up ! I discovered that it was a standard 5 pin connector with 2 unused pins that I labelled "Shield". You can see on picture 4 that when connected to any standard cable, the "shield" pins are just unused and don't connect to anything. Knowing this, It will be quite easier to repair Samsung devices (where I found this kind of connector mostly) : this is almost 100% compatible (except the anchor points) and a standard generic 5 pin microUSB does the same job really well. Maybe less sturdy but still functional. This was a quite nice discovery for me ! I just wanted to share, since I didn't find a lot of talk about 7 pin microUSB connectors on the Internet [link] [comments] |
I have made an electronic circuits simulator with pretty and simple UI. It's by no means feature complete. Please try it out.

Interesting screen connection method
![]() | I disassembled this "recalibrateable" Caliper and I was wondering why the LCD came off like this with no clear way for the signals to travel to it, I can only assume this is a very interesting way for them to recalibrate it without having to add more pins/pads. [link] [comments] |
