My first attempt at computational line art! This image is a representation of a sha256 hash of an input string, my name. Each ring represents 4 characters of the hash, and is the binary representation of the character's ascii value. A hash is a transformation of an arbitrary-sized value into another value of fixed size. Hash functions that are one-way, i.e. cannot be reversed, are the basis of modern cryptography and security on the Internet. Given this image, you wouldn't be able to reverse it to find out the original string, but every time I run the hash on the same string it will output the same value. The next step is to load this into my #AxiDraw and plot it on some actual paper!

I got @speedify running on a #YoloBox! Check out the link in my bio for the step by step how-to video! Why might you want to do this? Speedify lets you bond multiple internet connections for faster and more reliable livestreams, and since the yolobox has LTE, WiFi and Ethernet, it's amazing to be able to run Speedify directly to take advantage of all those connections at the same time! Thanks to @yololivtech for sending me these to review, and thanks to @speedify for the premium account to test this out! #livestream #yolobox #streaming #streamingsetup

Using the Sony ZV-1 as a top down camera today! Of course I don't trust it on USB power so I've got it connected with a DC coupler into the battery slot, which then means I need the extra bottom bracket to be able to leave the battery door open while it's also on a tripod screw. As much as I like this camera this is the most frustrating part about it! Check out this kit for a list of all the parts I used! https://kit.co/aaronpk/sony-zv-1-overhead-rig
My printers have been busy the last couple days! This is the complete #pk1stand lineup with both left and right Stream Deck attachments for both the 15-button and Stream Deck XL! We are still taking preorders of the MKII ATEM Mini stand along with the free custom name plate! Only a few more days to take advantage of this offer! https://pk1.tv

I'm still so excited to be able to offer these custom printed face plates for my #PK1Stand to you for no extra charge! If you buy the new PK1 Mark II stand during our preorder period, you can add on a face plate with your own text in it for no extra charge! Huge thanks to @yololivtech for sponsoring this deal! It wouldn't be possible without their support! The YoloBox and the ATEM Mini work great together giving you additional camera angles and audio processing capabilities beyond what the YoloBox can do itself, taking advantage of the YoloBox's all-in-one form factor for livestreaming on the go! Preorder your PK1 stand today from the link in my bio! #blackmagicdesign #yolobox #livestreaming #streamingsetup #livestreamer

First attempt at making a snap fit joint so I can make parts that move! It snaps together and definitely will not come out anymore, but also rotates smoothly! Looking forward to some interesting things I can do with this!
I moved my 3D printers to the kitchen where there is air conditioning and they are printing a lot better now!

Successfully installed the LED light bars! Next up is designing a mount for the Raspberry Pi to attach to the back of the printer.

Just wrapped up filming a talk about OAuth with the legendary @vibronet! Can’t wait to share this with you all at Developer Day! 🎉 https://www.okta.com/developerday/
The great thing about 3D modeling on an iPad is that you can go bike up a mountain and sit by the water and put the finishing touches on a design. Thanks @shapr3dapp!

The cool part about having a 3D printer is I can make stuff that I can't buy anywhere because it's useful only for myself. It's time to stick all my battery chargers to this pegboard!
