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

Remember kiddos, don't mix your wood and metal dusts!
Gosh it's been awhile! Many things are going on but few of them get finished. Here's something fun though - I converted an oily machine shop workbench into a workbar, and explored some new techniques along the way. Link to the full post in my bio ☝️
This little home shop just became quite a bit larger! The transit was questionable, but nothing broke. Planning a number of improvements to this tool, to soon enable quite a few future projects...
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...
