+Omar: I was in China for a few weeks (for some workshops and conferences in Shanghai and Shenzhen). I prioritized getting stuff I couldn't find in the US (often these are not even on Aliexpress, only on Taobao or in person). Got a few interesting Folk-related gadgets:
-  * "4K" projector (actually 1080p)
+  * [[https://item.taobao.com/item.htm?id=961137090756|"4K" "X10 MAX" projector]] (actually 1080p)
     * {{newsletters:img_1439.jpeg?0x200px}} {{newsletters:img_1432.jpeg?0x200px}} {{.:pasted:20260210-011824.png?0x200px}}
-  * Hachi Infinite M1
+      * I like the automatic focus mechanism. The projector is pretty bright
-  * Deli barcode scanners
+    * Got this for 888RMB ($126) on Taobao which is good for a good 1080p projector, but it's not 4K
-  * Portable printer
+    * It's really hard to find a genuine 4K projector. A lot of projectors advertise 4K, but it's just 4K input and they downscale on output to 1080p (pretty useless for us, since we want the actual resolution for text editing). Salespeople and product pages often don't know this distinction and will mislead you
+  * [[https://www.gtc-technology.com/products/hachi-k1-觸控智能投影機|Hachi K1 tabletop projector/touchscreen]]
+    * I got this for 1400RMB ($200) at a random store in HQB -- way cheaper than I've seen anything comparable online (I mostly see the M1 online; not sure what the difference is), or I think its original retail price
+      * I [[https://www.youtube.com/results?search_query=hachi+projector|heard about the Hachi devices]] years ago, but $600-1000 wasn't worth it to me to import, but $200 is easily worth it
+      * {{.:pasted:20260210-190828.jpeg?250px}} {{newsletters:img_0227.mp4?150px}}
+    * I think the K1 is the last model they put out and is China-only? It seems mostly similar to the older models I've seen online
+    * It's basically an Android tablet. Trying to root it and see what the sensor inputs are (cameras, laser line), maybe run Folk on it. It's a really nice form factor -- could also just copy it and make our own device
+  * Deli barcode scanners: the [[https://item.taobao.com/item.htm?id=631744239452|AA601]] tabletop & especially the [[https://www.delioa.com/products/es228wb-1/|ES228WB]] handheld
+    * I just liked the industrial design of these:
+      * {{newsletters:aa601.png?0x250px}} {{.:pasted:20260210-190411.png?0x250px}}
+    * The handheld ES228WB especially is very inspiring for a Folk gadget form factor and looks so much more modern than most barcode scanners I've seen
+    * (this makes sense, since barcode scanner is the equivalent of a cash register there -- they're very cheap, $10-20, very common, very consumer-facing)
+  * [[https://item.taobao.com/item.htm?id=977623174365|Guangzhou X-Dream X1200W portable A4/letter printer]]
+    * I got this on Taobao for 800RMB ($115) -- way cheaper than the Canon or Epson portable printers we've used in the past
+    * This is a totally viable printer for Folk if only we could get good drivers for it (I can only drive it from their iOS app right now, even their PC Linux drivers don't work for me)
-In general, my hope was that we could find competitively-priced devices in these categories, but wasn't that successful:
+In general, my hope was that we could find competitively-priced devices in these categories (that maybe are only available in China), but was only kind of successful. Let us know if you know of anything:
-  * Portable 4K projector
+  * 4K projector ($800 or cheaper, and/or less than 5 pounds) like the AAXA 4K1
-  * Pico projector
+  * Pico projector ($400 or cheaper) like the Ultimems AnyBeam
-  * Portable printer
