Ep 153:A 555 Teardown to Die For, Tetrabyte is Not a Typo, DIY Injection Molding, and Using All the Parts of the Trash Printer

Editors Elliot Williams and Mike Szczys catch up on the past week in hackerdom. It seems as if we're in a golden age of machine building as an incredible rocker-bogie rover is built to transport a child and mechanical simplicity automates the wet cat food dispensing process. We marvel at the ability to use G-code to decorate eggs (them being curvy in more than one direction and all). The we contemplate the ability to build and start a motor which will continue to run long after your own life ends. And perhaps it's time to add more layers to your PCB design playbook.

With our intrepid Editor in Chief Mike Szczys off being kind of a big deal in China, Managing Editor Elliot Williams is joined by Staff Writer Tom Nardi to talk about all the hacks that were fit to print over the past week. Join us as we talk about the wide world of custom mechanical keyboards, reviving a woefully antiquated display technology, building your own RC transmitter out of stuff you have laying around the lab, and the unexpected parallels between Pepto Bismol and rocket fuel.

Elliot Williams and Mike Szczys walk through the past week in hackerdom. There's a new jargon quiz! Do you know what astrictive robotic prehension means? We look at the $50 Ham series, omni-wheeled pen plotting robots, a spectrum of LED hacks, LEGO CNC for chocolate rework, and grinding lenses with a CNC mill. In the "can't miss" category are fingerprinting 3D Printers, and how NASA designs far beyond the stated life of an engineering project. Show notes at hackaday.com/?p=349624

Catch up on the past week of hacks with Hackaday Editors Elliot Williams and Mike Szczys. "AI on the Edge" is the buzzword of choice lately, with hardware offerings from BeagleBone and Google to satiate your thirst. We take on spotty data from Tesla, driving around on four bouncy-houses, reverse engineering a keytar, unearthing a gem of a dinosaur computer, and MIPI DSI display hacking. There are tips for getting better at commenting code, and making your computer do your algebra homework. Show notes at https://hackaday.com/?p=348778

We know you love the original art on Hackaday. Those fantastic illustrations are the work of Joe Kim, and he joins us as a guest on this week’s episode to talk about his background, what inspires him, and how he pulls it all off. This episode is still packed with hacks. Editors Mike Szczys and Elliot Williams somehow stumble into two projects that end up generating hydrogen (despite that not being their purpose). But that art angle this week goes beyond Joe’s guest appearance as we look at a hack to add green curve tracing goodness on a black and white CRT, and an incredible take on a string art building machine. We get a look at interesting hardware that landed on the clearance rack, ultralight robots that move with flex PCB actuators, a throwback to mechanical computing, and giving up control of your home heating and cooling to a Raspberry Pi. https://hackaday.com/?p=347900

Elliot Williams and Mike Szczys look at all that's happening in hackerdom. This week we dive deep into super-accurate clock chips, SPI and microcontroller trickery, a new (and cheap) part on the microcontroller block, touch-sensitive cloth, and taking a home X-ray to the third dimension. We're saying our goodbyes to the magnificent A380, looking with skepticism on the V2V tech known as DSRC, and also trying to predict weather with automotive data. And finally, what's the deal with that growing problem of electronic waste? Show notes at: https://hackaday.com?p=346585

Catch up on interesting hacks from the past week with Hackaday Editors Mike Szczys and Elliot Williams. This week we discuss the story behind falling lifetime ratings for LED bulbs, look at finite element analysis to strengthen 3D printed parts, ogle the beauty of blacksmithing, and marvel at open source Lidar development. We delve into great reader suggestions for Blue Pill projects sparked by last week’s podcast, discuss some history of the V2 rocket, and cover Chromecast control hardware, glowing home chemistry, K40 laser cutter add-ons, and more.
