on 02025-03-28"UniFlash" an opensource Unisoc/#Spreadtrum feature phone flash reader/writer. Cross-platform MediaTek feature phone dumping had been achieved long ago with MTreader. Now it’s time to do the same for Unisoc (ex-Spreadtrum) phones. And not only that, but also to be able to flash them and extract their compressed firmware contents!” #ghettobotics #electronics #hardware
on 02024-09-27#Spreadtrum firmware dumper for #ghettobotics. “1. Feature phones based on the SC6530/SC6531DA/SC6531E chipset. 2. So far, only a flash dump. Smartphones with Spreadtrum/Unisoc chipsets, but only tested on Tiger T310. You can read, write, erase partitions and repartition flash memory.” #electronics #hardware
on 02024-09-27“Amazing” #hardware Projects From Old Scrap Circuit Boards. Fake, removing components from salvage boards with tweezers without desoldering them. First project is an uncredited, unexplained Joule Thief cellphone charger that produces too-high unregulated output voltage (one commenter said, “When I plugged this into my phone everything blew up.”). Second one is a shitty high-distortion class-A darlington amp for an 8Ω paper cone speaker consisting of two NPN power transistors from a compact fluorescent lightbulb, a 220μF cap, and a 330Ω resistor. Still, he’s doing some cool #ghettobotics stuff with almost no materials or tools. By “Creative Goutam.” #bootstrapping #hoarding #video
