Instead they’ve opted to use Tuya’s WB3s chip. This is not compatible with ESPHome(at the time of this writing). Luckily this module is a chip for chip replacement of most ESP8266 module like ESP-12F wb3s chip Removal of WB3s module. I used bismuth to help me in the desoldering. https://j3ffrw.github.io/p512/ Thu, 01 Sep 2022 00:31:19 +0800 https://j3ffrw.github.io/p512/ Recently I had a need for a cheap IR Blaster for Home Assistant climate integration that doesn’t require a cloud to work. After a lengthy google search I found others were able to use a generic round Tuya IR blaster by reflashing them with ESPHome which suites my need. So I decided to get one for Php 390 in one of ecommerce site in my place. This one has a esp8266 chip. https://j3ffrw.github.io/p511/ Sun, 15 Nov 2020 00:31:19 +0800 https://j3ffrw.github.io/p511/ Here’s my assembly guide for LRTimelapse timer free Max an intervalometer on steroids. Where to get one. Contact Hans/Sheeba at forum.lrtimelapse.com Hardware versions There are several versions of LRTimelapse Pro Timer 3 and 2.511 , from the developer of LRTimelapse software, Gunther Wegner, this a commercial fully working unit, just buy the cable for your camera and off you go.

This steps were performed on the the following configuration of Ksger T12 Soldering station. Hardware Version 2.1S PSU version v2. https://j3ffrw.github.io/p509/ Mon, 21 Sep 2020 00:31:19 +0800 https://j3ffrw.github.io/p509/ Most desktop solder fume extractor that is available doesn’t work well, to suck in the fumes they either need to be very close or need to be on top of the parts your soldering. The filter that came with those extractor doesn’t work either, they are too porous to be able to properly filter the fumes. As an alternative, I’ve repurposed an air purifier as a fume extractor by fitting it with an adjustable duct. https://j3ffrw.github.io/p508/ Tue, 01 Sep 2020 10:31:19 +0800 https://j3ffrw.github.io/p508/ To remove the plug you’ll need to pry it off little by little on all sides using a small flat screwdriver. Chances are the plastic is brittle and when you try to pry it on one side one of the tabs might break off and will fall inside which is bad. Clean the dried oil on the surface of the hole, use a scrub pad if necessary. https://j3ffrw.github.io/p507/ Mon, 31 Aug 2020 10:31:19 +0800 https://j3ffrw.github.io/p507/ I initially tried to format the DS213 v1.22 built-in 8MB storage on my linux machine but the files ended up unreadable after saving a few screenshots and CSV. The first method I tried was from the official forum. http://www.minidso.com/forum.php?mod=viewthread&tid=3342&highlight=format, sudo dd of=/dev/sda if=/dev/zero status=progress sudo mkfs.fat -F 12 /dev/sda mkdir -p /tmp/p sudo mount /dev/sda /tmp/p -t msdos -o "fat=12" This essentially formats it to FAT12 but the files are unreadable or corrup once mounted. https://j3ffrw.github.io/p506/ Sat, 29 Aug 2020 10:31:19 +0800 https://j3ffrw.github.io/p506/ Now, normally I would hire a professional(someone who does this for a living) as it’s cheaper than paying my self on a per hour basis. But with this coronavirus spreading around in my area, the risk of having infected is greater than what I would be losing financially. I heard that you need at least Php 500K to get treated.
