Hacking & Experiments

A follow-up to the Yihau/WEP SMD Station Meltdown, testing the heater drive TRIAC and looking at the brushless DC fan motor. And how a TRIAC and SCR works. DaveCAD github Forum HERE Podcast: Download

Is a 1 CENT LDO voltage regulator any good? Dave tests the Shen Zhen Fine Mad! SC662K 3.3V LDO from LCSC a.k.a. http://www.superchip.cn Forum HERE

David looks at the pins on the Padauk PMS150 programmer for potential reverse engineering. TLDR; It doesn’t look easy to reverse engineer this protocol, it’s messy with lots of voltage levels, as Padauk said it would be. Just buy the programmer for now! There is also a Flash/EEPROM re-programmable version …

Using the Padauk programmer to program the 8 pin SO PMS154C micro and flash a LED on a breadboard. Forum HERE Podcast: Download

Getting the 3 cent Padauk microcontroller to blink a LED. Or at least the in-circuit emulator blinking a LED with C. UPDATE: LCSC have just said that they will offer a free programming service for a limited time to anyone. Just email them when you place your order. http://www.padauk.com.tw Forum …
