This was a major loss to thousands of old articles on this site sadly. I've dug around, and managed to get a better image from a KiCad import, click to enlarge and then you should be able to save the enlarged image, in high quality. I cannot update the original article for some reason.</description></item><item><title /><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/w/documents/1504/building-a-low-power-compact-lcd-display?CommentId=774fb728-577c-465f-b59f-f94231f2d065</link><pubDate>Wed, 19 Aug 2026 09:06:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:774fb728-577c-465f-b59f-f94231f2d065</guid><dc:creator>Mahipal1985</dc:creator><description>Hi Shabaz, I came across your “Building a Low Power Compact LCD Display” project on the element14 community and found it very interesting, especially the use of the PCF85176T with a reflective LCD and the extremely low power consumption. I am currently working on a low-power CO monitor project and I am looking to use a similar reflective LCD solution with the PCF85176T. I noticed that you have provided the schematic, Gerber files and source code for your original project. I have been studying the schematic and PCB design, but I would really appreciate some help understanding the design in more detail. If possible, could you please share the original schematic/source design file (for example, the Eagle schematic/project file), or guide me on how I can obtain/open the original schematic? It would be extremely helpful for me to understand the LCD pin mapping, PCF85176T connections, VLCD circuit and address configuration correctly. I would also be very grateful for any advice you can give regarding adapting this design for my CO monitor project. Thank you very much for sharing such a useful low-power LCD design with the community. Best regards, Mahipal</description></item><item><title /><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/adding-wireless-capability-to-custom-rp2040-rp2350-projects-pi-radio-module-2---anyone-tried-it?CommentId=f04f63ab-84dd-48e6-8bd2-540088c3c8c1</link><pubDate>Wed, 05 Aug 2026 21:26:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:f04f63ab-84dd-48e6-8bd2-540088c3c8c1</guid><dc:creator>shabaz</dc:creator><description>Here's a board attempt with two wireless modules (both don't need to be populated). Circuit diagram: The unusual board shape is needed to fit over the main PCB: The Sub-1GHz module (eByte E07-900MM10S) is not intended for LoRa, but the footprint is pin-compatible with a LoRa module (E22-900MM22S) if desired, but that uses a couple of extra pins, which I didn't wire up (they would need to be patched to GPIO pins on this current board).</description></item><item><title /><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/custom-manufactured-rp2040-boards-part-3---final-results?CommentId=87576a97-9fea-4221-873b-c822a67c2f40</link><pubDate>Sat, 25 Jul 2026 04:41:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:87576a97-9fea-4221-873b-c822a67c2f40</guid><dc:creator>geralds</dc:creator><description>Hi shabaz Super!

There's no easy way to screw in the board, because the holes are too shallow (they are just 2.5 mm deep), so I had to use glue (I used UV epoxy). End panels: Another thing I've learned; it would be good to use a right-angle button for BOOTSEL, so that a pinhole could be added to the end panel design, to make it easier to upgrade the firmware. Currently I would have to unscrew the case, or drill a hole in plastic, which isn't convenient. I need to modify the main PCB anyway, to add wireless to it. However for the current boards, I can use a daughter board, since the connections are on pin headers.</description></item><item><title>Forum Post: RE: Is it possible to read simultaneously from same sensor with python raspberry pihttps://community.element14.com/products/raspberry-pi/f/forum/57116/is-it-possible-to-read-simultaneously-from-same-sensor-with-python-raspberry-pi/236461Tue, 21 Jul 2026 21:20:00 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:e9b4c12e-5ed1-40dd-80ce-b6d40801ecc4dougwRPi is a sequential machine.

I think the main reason, is the boot partition may be FAT32, but the Filesystem is EXT4, like any other Linux drive, and could probably go as high as a 1TB as long as the format of the Filesystem partition, is EXT4.. I think it was if you kept the entire drive format as FAT32, yes, the physical limit is 64GB., but the image expansion will go beyond that.</description></item><item><title /><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/adding-wireless-capability-to-custom-rp2040-rp2350-projects-pi-radio-module-2---anyone-tried-it?CommentId=1c3c5aae-7412-4b33-91a8-8a9e808e0d88</link><pubDate>Wed, 15 Jul 2026 17:26:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:1c3c5aae-7412-4b33-91a8-8a9e808e0d88</guid><dc:creator>shabaz</dc:creator><description>Here's an attempt (the link to the KiCad files and Gerbers has been placed in the blog). The board size is 50 x 23 mm, which costs £6.67 for ten PCBs (I will populate these by hand, the parts are large and easy to solder), including tax/shipping. A combined board with this and CC1101 would be good, I might try that at some later point, since I can see use-cases for both together.</description></item><item><title /><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/how-i-built-a-raspberry-pi-3-sdr-radio-ground-station-with-openwebrx?CommentId=a1393952-94bf-455e-9a58-e5c7e9b80d7c</link><pubDate>Tue, 14 Jul 2026 21:06:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:a1393952-94bf-455e-9a58-e5c7e9b80d7c</guid><dc:creator>DAB</dc:creator><description>I have played with a cheap SDR.

The user menu is quite nice, the AI implemented a command history (just press the up arrow key to see previous commands) and also allows for editing within the current line using the left/right cursor keys. I might reuse this in other projects that require a menu too. Also, there's now a Python program called control_demo.py that will just cycle through colors using channels 1-3, it should be compatible with simple RGB DMX lamps either directly, or with a slight tweak. The program works by prefixing the commands with "$" and the firmware recognised that, and suppresses verbose output, so it becomes like a simple machine interface. This was just supposed to be a quick experiment, but I think it's almost a practical solution now, at least for some DMX use-cases.</description></item><item><title /><link>https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/dmx-tester-building-a-lighting-controller-and-test-tool?CommentId=da36cfc5-65b9-4543-b614-916f15d46873</link><pubDate>Mon, 13 Jul 2026 21:46:00 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:da36cfc5-65b9-4543-b614-916f15d46873</guid><dc:creator>shabaz</dc:creator><description>It looks excellent for events : ) I was thinking of low-cost non-moving one like this just for testing the code: I also saw small mirror balls are low-cost, and motors (some are battery-powered to make it easier to install on a ceiling).
