3D printed high torque gearbox - An electric hoist
Details from 3D printed high torque gearbox - An electric hoist
I made this 3d printed high torque worm gearbox. It called also winch, hoist or crane. The gearbox uses a 775 12V 13000 RPM (100 Watt) brushed DC-motor which it has 0.074 Nm torque and 13000 rpm. This 3d printed gearbox had a gear ratio of 98:1. So the...

Solar Shopping List
Log from Solar-Hydro
After digging through my collection of scrap building materials, I've revised my plan for mounting four concentrators in a box together down to three. It turns out that I've got at least twelve 2.4m (8') lengths of 4x2" pine, but only one length that's...

I should have my test board for the 2SK3018 transistors back next week, but in the meantime I've been thinking about other changes.In the interest of adding more I/O capabilities, I think I've settled on adding an I2C interface to the Q2. I2C is...

Extension Wires, First Flights, and Learning from Failure
Log from Hubsan X4 Replacement Frame
Nothing like a positive title, right? Spoiler: the first flight didn't go exactly as planned, but with any luck I learned a few lessons.My 28 AWG wire assortment and liquid electrical tape (yup, this is a thing!) arrived earlier this week. I reinstalled...

Blinking LEDs at 28 MHz
Log from LED Oscilloscope Mk. II
So I wired up some 74AC logic to drive the horizontal board, and hooked up an AD9200 ADC to the vertical board. I found that the maximum usable sampling rate was just under 30 MS/s, with good results at 28. The limitation seems to be the...

Solar Irradiance and comparing incoherent vs coherent "power" + CD Diodes, maybe + burn speed -> mW
Log from CD/DVD mechanisms and cartesian thinggie[s?]
UPDATE (12-10-15):WARNING: HORRENDOUS MISUNDERSTANDING MAY FOLLOW!Take all bits regarding mW vs. mA with quite a bit of speculation! (new log-entry to follow).----------OldNote:This log has changed quite a bit since its introduction... all additions...

Electronics Design (Redux)
Log from Squirco Smart Home System - Sensor Network
Two project logs ago I posted pictures of what I called "final" hardware. That was a total lie.I'm going to make up for it by detailing the evolution of the hardware through some of the major revisions, as well as the decisions that drove the design...

5V Logic on a Z80 Retrocomputer
Details from 5V Logic on a Z80 Retrocomputer
I bought a bunch of Z80 parts on ebay for cheap ($10 plus shipping). The parts came on a PCB which had not yet been flow soldered. From the date codes of the parts it looks like it was stuffed sometime around 1999. All I had to do was straighten...
