Things that don't work
Log from FPV for Mavic Pro
I'm an iPhone user, so the phone i use with the Mavic's controller is an iPhone 6. The controller plugs into the lightning connector on the bottom and appears, I assume, as a USB device to the phone.My original idea to get HDMI out was to use Apple's...

Hotend testing framework
Log from Multi-Material Hotend
With the AnyCubic's Kossel assembled, I'm replacing the standard hotend assembly with a 3d printed carrier designed to accept the high-temp resin hotend. You can see the frame here: The hotend will slot into place and be secure with the fan bolts. I...

The 2023 update: I'm not dead
Log from Reverse engineering the Rotor
First of all, apologies for the lack of activity. Turns out reverse engineering is not all fun and games: apparently there's a lot of hours of tedious and repetitive work to do (who would've guessed, lol). University work and a general lack of time (and...

The supports/bearings
Instructions from Projector Screen
Drill two holes, almost all the way through, two blocks of something the same size as the outer diameter of your roller blade bearings. It's a common size like 3/4 or 7/8in. Make them identical. For the hole you are after, you need a nut on the threaded...

Log from Power On Sequencer bis
Rod Elliott designed a power-on delay at http://sound.whsites.net/valves/ht-delay.html using the same trick as I described in a previous log at https://hackaday.io/project/11681-power-supply-power-on-sequencer/log/55676-latest-considerationsspy on the...

Center-line extruder mount.
Log from Arcus-3D-C1 - Cable 3D printer
I think I may move the extruder to half way up on the center-line of the push-rod.If I position it right, it won't move much and it's mass will actually help to stabilize the end effector.Mocked up the basic idea in OpenSCAD while my top corners are...

Welding and Articulation Test
Log from Autonomous mini-tractor
I got the frame welded up and threw on some lawn mower wheels and threaded rod to test the double-articulation. I was afraid it might be too sloppy, but it's actually very solid and should ensure that the mini-tractor has good traction. The turn radius...

Engine Block
Instructions from SpaceX Falcon 9R Lamp
I recommend gluing the engine block to the pipe first, as once it’s attached you can simply thread the support rod into the rocket, allowing easier clamping. Apply some Gorilla Glue to the bottom end of the pipe and place the engine block on it, using...

Throttle and Choke Servos
Log from Goliath - A Gas Powered Quadcopter
Connecting a servo to throttle and choke is one of the last things to be done before the hover test. I've been taking a look at the hardware on the engine to see what's required.The engine user manual doesn't cover anything regarding the mechanical...

Minimizing backlash
Log from Computer Numerical Considerations
So far backlash hasn't really been a concern but the other day I had this idea that should help reducing it. It's similar to what was done in this machine which was recently featured on the blog where two nuts were pressed in opposite directions by some...

A new high accuracy tilt sensor
Instructions from A new high accuracy tilt sensor
It's time to coil! We need 5 layers of 0.25 copper coil for each coil. To make your life easier you can DIY a simple coiling machine like this:Or, if you've got access to a lathe, you can use that too. Just strengthen the previously prepared cell to...

Sound familiar?https://www.instagram.com/p/BTJxQdnFdrS/?taken-by=vanhackspaceThe...
