Brightening my DayLilies

April was a tricky month. Formlabs is bustling; we announced a big new product to the world and now the days are spent on the final tweaks to get it into our customer's hands. And what is my role in all of this? I am, well, focused on growing some vegetables in our still-too-short New … Continue reading Brightening my DayLilies →

Analog PWM generator

I was watching a video by W2aew about creating a stair-stepping circuit from analog components, and I felt like trying it out. After starting, I realized I didn't have a 555 timer, Which is used to create the pulses that step up the voltages. However, I did have some simple LM358 op amps, so I decided … Continue reading Analog PWM generator →

What I've been up to recently

Summer's in full, heh, swing out here, so @decidedly_unremarkable and I put together a hammock stand! It's made out of some no-so-great plywood and electrical conduit, plus a few bits of hardware to hold things together. Blog post to follow w/ instructions if there's any interest in that! It's pretty great to enjoy some R&R outdoors without planting two trees and, y'know, waiting 20 years 🌳-_-🌳

A quick & dirty #functionalprint this evening, to repair a busted latch on a headlamp. The printed clip is simply CA glued to a flat face around the charging flap - you'd hardly know it wasn't original!

I solved a mystery and fixed my old #printrbot 's filament guide over the weekend! Small writeup at the bio link, for those curious. There are newer printers and better extruders to be had, but this cost me nothing and took only an hour or so to complete, so I'm satisfied. I just need to make objects again...

I'm making me jelly! This is made from #local kumquats, which lie somewhere between grapes, oranges, and lemons.

Finding the remaining puzzle pieces for the shop - a shelf made out of @makerpipe junctions and conduit, and a @_husky_tools_ adjustable workbench for wrenching. It's great when things fit together just right 😌

New lab! I've been working on this space for the past month or so, and I'm excited to... keep working on it 😄 (and also maybe the projects on the table there...). And there's a link in the bio to a blog post I wrote about the process (well, actually it's kindof a book review...I dunno)
