Power & battery
Log from Light bottle
I tried to experiment with AA battery instead of 18650 Li-Ion. The design is slightly smaller and lighter, but I think it will be worse on the long run. 18650 can provide more power and it's easier to have step up and charger on the same board.I recycle...

Sensors and camera
Log from Autonomous watering system
The Raspberry Pi board has plenty of GPIO lines available for hooking up sensors such as DS18S20 1-wire temperature sensors:http://www.raspberrypi.org/forums/viewtopic.php?f=44&t=65137I might also hook up a soil moisture sensor (measuring capacitance)...

Need to make this more compact
Log from Motorcycle Rear Vision Helmet Mounted Display
while I'm waiting I have plenty more todo. All this gack is going to be packed inside my helmet somehow so I'm thinking of making everything smaller (except the screen). I'm going to chop off all the excess wiring and disassemble the RX unit to see if...

Build Updates - 1/10/17
Log from WiFi Controlled Curtains
I went to Menards over the weekend, and picked up some polyester rope, which has almost no stretching issues. I was previously using 550 paracord, as it was all I had on hand. Additionally, I now have 3 turns of rope on each pulley, so there is plenty...

ALU functionality
Log from One-instruction TTL Computer
If I'm using the '181, I could make all functions available to the compiler. I mean, there could be some efficiency gains in the more obscure functions. Since there's 4 bits for the function select pins, one for the mode pin, and a carry input, that's...

Sampler on the Noise Nugget
Log from Noise Nugget
I implemented a sampler mode for the Noise Nugget. It plays a single audio clip at different speeds to give the illusion of different notes.For the moment the audio clip is stored in the main flash memory, with the code. There's not a lot of space available...

Boards Arrived
Log from RunTinyRun
The PCBs have arrived. I'm not impressed with the quality but hopefully they'll work. Lesson learned No.1: check the minimum silkscreen specifics of the fab house. I did at some point but, changes after changes, I ended up with characters smaller than...

Getting to know your Robot Vacuum
Log from Shark Robot Vacuum Reverse Engineering
STEP1: Communication, sprechen sie beep boop? So a great place to start with almost any reverse engineering project is finding the UARTS. One difference with the L02 PCB vs the L01 is the lack of silk screen information besides some model info...

Reuse for Revamp
Log from CT system Revamp
The 3D Slicer is perfect to show the output images for the doctor´s diagnostic. However, there is a couple of things: 1) 3D slicer works with 2D images. It can use plenty of file formats, but again, 2D images.2) CT systems does not produce...

It's Alive!!
Log from Compost Shredder Upgrade
Well, I sprinted through the week and got the shredder working! Found the master link I needed to close the chain.split the chain to the length I needed, and hooked it up to the sprockets.I'm very pleased that it fits nicely over a bucket. I don't have...

Gear model printed, powered by a stepper
Log from Strain Wave Gear with Timing Belts
OverviewA 3D printed strain wave gear, using a HTD 300-5M-20 and 608 bearings. The belt has 60 teeth, for 30 revolutions of stepper the outer gear rotates once, resulting in a -30:1 gear ratio. Bill of materials Material Quantity Dimensions HTD belt...

Log from 3D Printed Robot Actuator
Typical Cycloidal Transmissions consist of four main sections. Input shaft and eccentric bearingCycloidal Gear(s)ring pins and housingOutput rollers and shaft The way that the sections are arranged are with the input shaft on one side and the output...

Testing the first prototype
Log from simple pick-and-place head
I transfered the basic idea into one single 3D-printable part and -surprise, surprise - it works! This construction was my first time using FreeCAD for designing a non-trival part. Information about the new part/body model in version 0.17 isn't as easy...

Log from Poor Man's Mini 3D Printer
I managed to increase my machine's bed size from 35x35x35mm to 40x40x40mm. It may seem small but the 10mm increase in dimension is huge for me. Every millimeter helps! It all started when I learned that there are stepper motor sliders similar to the...

CFRP arrived, build starts this weekend!
Log from GimbalBot
Everything arrived, including the 8' long tube stuffed with bubble wrap and CFRP square tubing. Exciting! Two CAD model changes to make prior to getting out the carbide-tipped jigsaw and Space Glue:1) I'm going to increase the width of the pitch ring...
