Genmitsu 6060 XY-Axis Extension Kit for PROVerXL4030 – DIY desk and folding cart

Karl here. I teased this article in the final review of the Genmitsu PROVerXL 4030 CNC Router. I was really happy with the base kit. You can check out all my thoughts there. SainSmart recently released an extension kit that I have now had for a few weeks. It increases the stock size from 300 x 400 to 600 x 600. That is what we are here to check out today. When I inquired about the kit I didn’t realize how boring a review of the kit would be but I will do my best to bring some additional value beyond just unboxing and building experience. Unboxing The parts list is minimal 2x Y-axis Aluminum Extrusion (lead screw included) 2x X-axis Aluminum Extrusion (lead screw included) 2x Front/Back Plate 7x Drag Chain 9x Drag Chain 4x Hexagonal Wrench, 4mm, 3mm, 2.5mm, 1 mm The original kit came with some decent […]

Genmitsu PROVerXL 4030 CNC Router Review – Mods & Projects

Hey, Karl here. Today I am writing about my opinions on the Genmitsu PROVerXL 4030 CNC Router and sharing the projects that I have done. My initial review was published back in January. I have been working with the tool for several months now and I have had a lot of fun. I have also gained a ton of experience and am really proud of what I have been able to make. I attribute my success to doing my homework and not doing my usual feet first approach. Let’s start with my opinions then showcase the projects I have completed. First opinions. The machine is well thought out and the build quality and materials are good. Other than a few modifications I outlined in the first part I have done nothing else. I installed an rpm meter but found that it was unnecessary. I don’t even look at it anymore […]

DIY Raspberry Pi Compute Module 4 NAS supports up to four drives

We previously noted it was possible to build a Raspberry Pi CM4 NAS using Wiretrustee carrier board with a built-in Marvell 88SE9215 PCIe to SATA controller and four SATA connectors. But Mebs just created his own Raspberry Pi Compute Module 4 four-bay NAS with his own carrier board equipped with a PCIe socket used to insert a PCIe SATA card, as well as a neat 3D printed enclosure that took 6 days to print. This carrier board design is actually derived from the official Raspberry Pi CM4 IO board with only the interfaces needed for the NAS to make it smaller and fit within the width of a standard 3.5″ hard drive. It was also made as simple as possible because it was Mebs’ first PCB design. This leaves the board with Gigabit Ethernet, one HDMI port, a USB 2.0 port, the PCIe 2.0 socket, as well as some headers […]

iPod Classic given new life with Raspberry Pi Zero W & Spotify

Guy Dupont got a bunch of 2004, fourth-generation iPod Classic MP3 players from his mother-in-law, and instead of playing MP3 files on the media players, he decided to repurpose one with a Raspberry Pi Zero W to be able to stream music from Spotify over WiFi. The resulting project is called sPot (ess-pot), and looks just like an original iPod, but it’s a Linux device that can stream/search via Spotify with a UI written in Python and based on the original iPod experience. But apart from the enclosure, and the original “click wheel” there’s not much left from the original design. Besides the Raspberry Pi Zero W SBC and iPod enclosure, the sPod includesAdafruit Mini LiPoly/LiIon USB Charger and PowerBoost 1000 Basic boards for charging and power management, a 1,000mah,3.7V rechargeable li-ion battery, vibration motor discs For haptic feedback, a 2-inch Adafruit TFT display, and a few other components, wires, […]

Lisperati1000 Lisp portable programming workstation features Raspberry Pi Zero W, ultra-wide display

Lisperati1000 Lisp Programming Ultra-wide display

Conrad Barski (Lisperati) wanted a portable “workstation” to write in Lisp and see all those parentheses. Since there aren’t many devices with an ultra-wide display, he decided to build his own “Lisperati1000” ultra-compact Lisp programming workstation powered by a Raspberry Pi Zero W, and equipped with an ultra-wide 1920×480 8.8-inch display, a compact keyboard made of Cherry Brown switches, and a 4,400mAh dual battery all housed in a 3D printed enclosure. When Conrad first showcased his little handheld computer on Twitter, he first claimed only 3 will ever be built, but think quickly got out of control with the project being featured on Hacker News, and he changed his mind after seeing the popularity of the DIY computer. UPDATE: Due to high demand, I have decided to fund a project to release this as a kit. If you are an electrical engineer and/or know about machining Aluminum, please get in […]

MutantC v3 open hardware DIY UMPC works with Raspberry Pi and compatible SBC’s

FOSDEM 2021 open-source developer event will take place online later this week, and yesterday we compiled a list of talks, with one entitled “MutantC PDA introduction – open source and hardware PDA shell” piquing my interest. The talk will be about the third revision of the hardware which allows you to create your own UMPC or handheld computer powered by a Raspberry Pi SBC or other compatible single board computers including Asus Tinker Board S, PINE H64 Model B, Banana Pi BPI-M4B, among others. MutantC v3 is versatile and highly customizable as can be seen from the specifications highlights: Supported SBCs – Raspberry Pi Zero, 2, 3, 4 and compatible. Arduino for keyboard – SparkFun Pro Micro 5v/16Mhz or SparkFun Qwiic Pro Micro – USB-C Display – 2.8-inch, 3.5-inch, or 4-inch “GPIO” LCD such as AdaFruit PiTFT 480×320 display Custom PCBs for display, mainboard, and thumbstick Expansion External 12-pin “docking” […]

Stripped-down Raspberry Pi 3B+ SBC powers YARH.IO Micro 2 DIY handheld PC

We’ve already seen a few DIY Raspberry Pi-based handheld computers in the past with the likes of Zero Terminal V3 or hgTerm powered by a Raspberry Pi Zero and a stripped-down Raspberry Pi 3 board respectively. So why not another? YARH.IO Micro 2 DIY handheld PC is based on a Raspberry Pi 3B+ SBC stripped from its Ethernet port, whose double stack USB connectors have been replaced with single stack USB connectors. The DIY computer also adds off-the-shelf parts with a 4″ touch screen display and a Bluetooth keyboard without touchpad, and gets its power from a 3,500 mAh battery. YARH.IO Micro 2 key components and features: SBC – Stripped-down Raspberry Pi 3B+ SBC Display – HyperPixel 4.0 4-inch IPS display with 800×480 resolution, touchscreen from Pimoroni Keyboard – 49-key mini keyboard with Bluetooth 3.0 ($10) USB – USB straight and right-angle connectors for four USB ports around the device […]

Sainsmart Genmitsu 4030 review – Unboxing, mods, and first cuts

Karl here. This will be a long one but I haven’t had this much fun with a product review in quite some time. I don’t consider myself a complete noob with CNC routers but I have only scratched the surface. Learning new things really drives me and being able to make more permanent things is very satisfying. I have some experience with the Sainsmart 3018 CNC router. I had a lot of fun with it but the build volume was on the smaller side so really limited on what can be done with it. I still recommend it as a starter CNC router and as a good stepping stone to get your feet wet and the Genmistu PROVerXL4030 as the next step. I was able to make some cool things with the 3018 and I hope now to take it to the next level with the Genmistu 4030. Before we […]
