I'd write you a shorter letter if I only had the time.
Log from Holiday Blinkenlights in 1K for about a buck
When you are writing prose, brevity can be difficult. You have to think very carefully about how to express your ideas concisely and achieve maximum impact. Often, it's simply easier to dump the contents of your brain, and just keep writing and writing,...

The Effect of Colloid Particle Size
Hacker page by bob
The Effect of Particle Size h1>The Effect of Particle Size Compare a large and a small sphere. The diameter of the large sphere is double that of the small sphere. The area of the large sphere is four times that of the small sphere. The volume of the...

Chains, sprockets, shafts and bearings
Log from Woody the Electric Four Passenger Bicycle
woody is using BMX cranks because they allow very small sprockets. Below is one of two assemblies before welding. The bottom bracket was turned on the lathe, and the two plates were made by sendcutsend. And here it is bolted in place. The holes...

LM317
Hacker page by Elena Smith
LM317 is a positive voltage regulator with three different terminals Adjust, Vout, and Vin respectively. It can supply the output voltage in a range of 1.25-37V and a current of more than 1.5A. It has advanced line regulation...

Making it run quietly
Log from The Spice Must Flow Sand Table
I wanted to make the mechanism run quietly even as it ran fast.Tests showed that even at high microstepping ratios, speeds much over 100 mm/sec resulted in objectionable motor noise. Other sources of noise included the belt teeth hitting the smooth...

Guesswork and theory
Log from MPPT for low voltage solar harvesting
@Dan Maloney is wondering where this is going, so that now makes at least two of us. Time to put a bit more thinking into the concept. I admit I am getting a little confused about energy, charge and conservation of current between the PV buffer...

Down the Rabbit Hole
Log from MPRT - Modified planetary robotics transmission
Optimisation of the Original MPRT So okay, I decided to see if I could optimise the original MPRT. Not a trivial task, but doable with brute force: For each Pressure Angle (PA) from 15 degrees to 25 degrees in steps of 1 degree.For each Diametral Pitch ...

Log Entry 1: Progress So Far
Log from Excel-ARK Kinetics Coil Gun
in this log ill add pictures for all of the components ive printed so far. I am currently printing the inner barrel (with coil stops) at about 15.3" (388.5 mm) tall with about a 1.25" radius. Did a few test prints for the interface...

PCB: first try
Log from Robot Radar Module
I designed a 32x32mm breakout PCB for the A111 sensor today. The datasheet says you need a solid ground plane on the top layer. I did the best I could using the OSH Park 2-layer rules. The reference PCB sold as a development module...

Build Report Version 15
Log from Webot
Overall it has been a success. I tried Kicad for the first time and the board is largely functional. The new 3D printed fastener concept is working well and the gears are held in better than they have ever been.. But as I mentioned before, it is...

What I have Learned
Log from A 2.5D Slew Ring
What I have Learned Okay, I have not built anything yet but here are some observations: Although the path is longer it was good to start with what can be cut with a laser cutter (2D) and then regroup the layers for a CNC milling (2.5D). Keeping both...

Solar Powered Watering for the little greenhouse
Details from Solar Powered Watering for the little greenhouse
I was getting water for the greenhouse the other day out of an old cow trough that fills with rain water. It is nearby and you don't need to wade into it to get the water. Sadly, you do need to watch for polliwogs as they seem to take up...

Air Plugs
Log from Solar filament drier
Burned $60 or twice the cost of a roll of TPU to get this started, not counting spare parts. The AHT20 sensors have a single fixed address which requires 2 I2C busses. We thus have 5 required pins: 1 MOSFET push pull, 4 I2C open drain. ...

3D Printed Vortex Particle Separator for Shop Vac
Details from 3D Printed Vortex Particle Separator for Shop Vac
Intro & Project GoalsI have a wee sized shop measuring a measly 12' long 8' wide and 9' tall. So, I need a small dust collection system. I also wanted the system to be more efficient than just having a shopvac alone. Also, since my shopvac is so tiny...

Start of pcb wrapup
Log from Bench power supply
I'm back on the project, slight distraction as I finished the digital wall clock I started 19 years ago.I have been busy gathering up the schematics and re-glueing and testing them. things have come togethor enough for me to start building one of the...
