Making a tap, angle-brackets, and a screw-driven linear-axis.
Log from rotary-tool-drill-press to Drill-Press conversion
I needed a tap... didn't have the right size/threading...Inspired by the self-tapping bolts I found earlier, I tried to make one, myself... and it works, amazingly well, with aluminium, anyhow.(I tried a *much* smaller one, which worked great for about...

esot.eric's upper axis
Log from Mini PCB printer
Hello! It's been a minute...So here's where I (@esot.eric) am at with the ol' #Mini PCB printerClick that "Read-More" link, below!---------- more ----------I decided to go a slightly different route than the whole "mini" part. For my purposes, that means...

The flap
Log from How to use an aerial 36 inches lens
Using 5 mm thick Dibond, the same material as the blade, it's going to be the same thickness and that what's needed. Here's the second cutting cession with a metal lathe tool with sharp flat edge. Searching for a thin strong metal around the shop, this...

Quick update
Log from DIY Electric Vehicle from Recycled Parts
Sorry for the long delay since my last update! Work has been continuing, though was a bit slow through January as I had a lot of other things taking up my weekends. While the car is at a friend's place for the mechanical work, I can only work on it one...

Brain-dump lest I forget...
Log from CD/DVD mechanisms and cartesian thinggie[s?]
Kinda burnt-out, been working toward some sort of functional PCB-CNC/rotary-tool system, all day.Decided to use the groovy microscope-slide mechanism my Pops found for me, but not exactly sure *why*, as it's been difficult to come up with a driving-solution....

The Servo
Log from Web powered antique wind gauge
Wow this thing is cheap. I shouldn't be surprised, it was!First thing was to connect it up to an Arduino running the Servo Sweep example just to check it works. It does, but it's pretty noisy!In trying to connect it to the gauge, I'd been hoping that...

Design Detail: Coupler
Log from Syringe Pump
Thought I'd have it all done by now, but everything takes longer than you think it will! Let's pause along the way and look at a few design details that might be innovations - maybe even useful innovations!The first innovation is in the coupler that...

Build Log 5 - Head Movement Servos
Log from Animatronic Stargate Helmet
More work done. The 10-32 rod end is threaded into a 3/8" rod and the rod has a collar with a set screw that holds it in place. The collar is positioned at the top of the main helmet body and moving the rod in the collar allows you to adjust the distance...

Installation
Log from Anglerfish for Bikes
In the last log, we had the firmware working. Previously we had the mechanicals and the electronics done. Now it's time to install!I'm still not sure how this will be permanently affixed to a bike. I'm thinking it probably will need to come apart (the...

First test successful
Log from 12V Lasercutter
The first version is working . G-Code interpreter can read G-Code now. However, just linear interpolation is implemented yet. I used a pen and paper to make the geometry visible. The free software InkScape was used to generate the g-code. Inkscape is...

In the Beginning
Log from The ERB (Electric Rescue Bike)
This project started in the Spring of 2015 when I won a grant for $2,500 to build a proof of concept electric bike to show the Amherst Fire Department. It really got going that Summer, when I attached the Lightning Rod's mid drive kit to my Iron Horse...

Throw hardware at it.
Log from Arcus-3D-P1 - Pick and Place for 3D printers
I got on another kick of trying to design the perfect 3D printable press fit D shaft coupler.It needs to be perfect, as error here will show up literally everywhere.Well, a couple dozen prints later and I still couldn't zero in, so I gave up and...

3D printed camera mount
Log from Ultimate running aid
3D printing finally allowed lions to mount the gopro on a carbon fiber rod instead of aluminum angle rod. It was much more stable & the energy burn was much less. It only burned 280mAh/mile. That may be a charging anomaly, but...

Prototype 2: Construction
Log from Peristaltic Pump for Beverage Dispenser
Construction:1. First, I 3D printed the casing and rotors as intended. However the bottom rotor's extrusions were not successfully printed and as such I had to make some final minute adjustments to the design.2. I attached the motor to the casing using...

Hardware Design
Log from Astrophotography Star Tracker
The hardware design is relatively simple. Since it is a single-axis tracker, it only needs one degree-of-actuated-freedom. We also need the ability to orient the system according to the latitude to square up the system to the axis of the Earth's rotation....
