    I'm I the only rocket hoarder??

    I spent the afternoon cleaning up the Rocket Barn, and have come to realize I am a serious hoarder. I'm not talking about buying things I won't immediately use (that's a problem too...), but keeping things I KNOW I should just throw away, "just in case".... Like these fins... "I better keep...

    Hacking satellites

    A Phd student gave a presentation at blackhat this year on how easy it is to hack satellites. You might think that the satellites orbiting Earth are secured against unauthorized access but sadly it seems that is not the case. The belief that satellites are secure is mostly based on the...

    cheap bionic hears for altimeters

    A few years ago I bought some cheap modules on eBay that converted sound SPL to light-up LEDs to make it easier for us old-timers to hear altimeter beeps on the bad - https://www.rocketryforum.com/threads/altimeter-beep-counter.160146/post-2013803 . I did get it to work, but it was excruciating...

    3D Printing Rocket Tree - Display your LPR rockets!

    My LPR rockets were taking up way too much space displaying them horizontally, so I built a Tree stand to get them off the table and up in the air. Have three different sections - one for 18mm, one for 24mm, and one just to add height/space between rockets. Each section spins independently of...

    3D Printing 3d printed multicolor BSG Colonial VIper 38mm

    Just put up V1 of a 3d printed Colonial Viper. This was my first attempt to use Bambu Studio's "Project" capabilities. You can assemble, and disassemble the rocket in the software to see how it's put together. Three plates worth of printing, and many, many filament changes...

    3D Printing Review - Bambu Lab X1 Carbon 3d printer

    I've owned a LOT of 3d printers over the years. This is the first time I'm "reviewing" a printer. I'm reviewing it because it is so different, and after a couple of weeks of testing, contains a number of new capabilities that we are likely to see in the next few generations of printers. I...

    3D Printing Apollo Control Panel STL's on kickstarter

    I've taken a break from backing Kickstarter physical products, as most people wildly underestimate how long it will take, and how much it will cost resulting in either never getting the product, or getting a product that has taken significantly longer and is significantly worse than what you...

    Rocket Barn Weathervane

    I moved to Virginia last year, and have been in the process of building a "Rocket Barn" for all of my goodies - it's taken a long, long time, but I'm almost done. I'll do a separate thread on the rocekt barn itself - when I decided to put a cupola on the barn, I knew I needed a weathervane to...

    Coke Mentos and NASA

    I was searching through my google photos for some paperwork I had taken a photo of, and the letter below popped up. I can't remember who sent it to me, but I laughed out loud a second time. Hopefully "Mr. Jones" isn't a forum member :) Sadly, Steven Malkovich isn't a NASA employee, nor has...

    3D Printing Monster 3d printer build

    Every year, Alibaba holds a "Global Shopping Festival" on 11/11. It's basically a copy of Amazon prime day, but given Alibaba's size, it's turned into a much bigger sale. Last year Alibaba did over $84 BILLION during their 11/11 sale, vs. Amazon doing just shy of $12 Billion for prime days...

    Rocket keycap for charity

    Was messing around on drop.com and found these keyboard caps they are selling for charity. The one for St. Jude is a rocket, for $10. They claim 100% of the proceeds go to Charity. I have no relationship with Drop, and generally believe they are overpriced for things that are available...

    So, I'm really enjoying The Mandalorian. There seems to be a lot of new ships / rockets / blades, etc... and I keep asking myself - could that be a rocket? I haven't seen anything yet has compelled me to build it. Has anyone else seen something that would look really interesting? There is the...

    $21 paint booth

    I bought one of these tents a while ago, and use it as a hillbilly paint booth. Just put a lazy susan on the bottom and it will contain most of the overspray. https://sellout.woot.com/offers/abco-tech-instant-pop-up-privacy-tent

    Sold Celestron Nexstar 8 with lots of accessories

    Given the crossover between rocketry and astronomy, I thought I would try and offer our family telescope here before putting it up on ebay/craigslist. This is a Nexstar 8, not an 8SE, 8i, or 8 evolution, but the original 8. Has the all of the goto functionality and great tracking, but starts...
