Projects

Hi! Welcome to my website. I occasionally post updates to cool projects I am working on here.

Adapter Board for CH330N
April 2019

Adapter board for a CH330 USB to UART IC. This thing is pretty small, at about 1 square inch. It's an ultra bare bones serial adapter that can be made for about 75 cents. Right angle female header pins stick out from the center on the bottom for UART and and a USB Micro B port is soldered to the top.

New 3D Printer part cooling.
April 2019

The copper looking pipe is a new type of part cooling. To reduce the physical size of the gantry, the motor is attached to the frame, with a teflon hose leading to the outlet. The blower motor will most likely be a bldc motor with a 3d printed compressor housing, as high pressure will be needed to produce reasonable air flow. The exact size and shape of the outlet will need to be tested and iterated on.

New 3D Printer gantry.
March 2019

Close up of the printer gantry. It will be a CoreXY based printer, with a remote direct drive extruder, remote part cooling, and a carbon gantry. All these design decisions lead to an end effector thats small and lighweight, increasing potential print speed and reducing the footprint of the printer relative to the build volume.

New 3D Printer.
March 2019

New 3D printer build. I got quoted over $300 for a single PLA print and decided it's time that I get large scale, reliable 3D printing capability. The print size will be rougly 350 mm^3, enough to print the entire electric bike pulley mold in one go.

Don't try this at home.

Whats cheaper and more dangerous than a Lime scooter? Lemon scooter!

SoldAR.
March 2019

SoldAR. We hacked a TS100 Soldering iron and used the MagicLeap AR headset to create an assisted soldering tool for RevolutionUC.

Don't try this at home.
February 2019

This is Bit Bandit. It uses OpenCV trained on an image set to activley look for empty power outlets, plugs in, and starts mining bitcoin with the GPU strapped to its back. Entry for MakeHarvard.

derpyBot!
February 2019

This is a robot we built for hackCWRU. It uses a stepper motor direct drive and time-of-flight sensors to simulate LIDAR and map the world around it as a 2D point cloud. It's not true LIDAR because the sensor only sweeps at about a 160 degree angle and not all the way around.

Drivetrain build
January 2019

Drivetrain and suspension for a new autonomous robot build. Using an oDrive, brushless RC motor, and external encoder to make a cheap DIY brushless servo drive.

Ebike speedometer.
January 2019

Speedometer mockup for ebike. Next thing to work on once the drivetrain works.

Prototype driver board for
January 2019

New Prototype driver board for the LED Nixie Clock project, this time with BLE (Bluetooth Low Energy). The microcontroller is an Adafruit Feather 32u4, allowing me to control the entire clock from my phone.

CAD of SMD NRF module.
January 2019

Rendering CAD models directly on the Nifty Parts website using WebAssembly and OpenGL ES. OBJ files had to be utilized because they store model color, and everyone wants color these days.

Carving a mold for the pulley.
December 2018

Carving a mold for a pulley on the Inventables X-Carve. Unfortunetly, this machine is not stiff enough for anything more demanding than small sign carvings. Will have to 3D print it instead

Large CNC router.
December 2018

Large CNC router being built for the Innovation Studio at OSU.

Main drive pulley for ebike.
December 2018

Main drive pulley for the electric bike. It's an odd shape because it snakes around the rear brake caliper and bolts to the disc brake .mounting pattern. It will be layed up in carbon in a 3D printed mold.

Wire Vise
September 2018

Wire vise mockup designed to help solder wire connections of various sizes. Stand off and PCB contruction, meaning that I can get kits made at a PCB mill for real cheap.

18650 Battery for ebike.
November 2018

Battery pack for the electric bike project. Made up of 39 LG HG2 18650 Li-ion cells, its rated at 48V, 9Ah, 90 amps continuous discharge, in 13S 3P configuration. Definately going to use Li-ion for more projects.

Because why not!
November 2018

CakeBot can only ice cookies. Won at Hakron 3000.

Ebike motor mount and tensioner.
November 2018

Motor mount and tensioner, printed in ABS. Jacking bolts against the frame are used to set the belt tension.

Ebike belt tensioner.
November 2018

Captive nuts inside belt tensioner for electric bike project. Perfect retention with 0.25 mm interference fit in ABS.

Ebike motor mount.
September 2018

Other side of the Electric Bike motor mount.

Compact printer design.
September 2018

Compact 3D printer design. Your average 3D printer only uses around 15% of it's volume to make parts. This is upwards of 40%, however there is always room for improvement.

Ebike drivetrain layout.
September 2018

Electric Bike drivetrain layout, in Solidworks.

18650 battery for the tank.
July 2018

18650 battery pack for the tank. Made up of about 100 used Samsung cells.

Tank. Is it done? No. Never done.
July 2018

Top of Tank bot with the access covers removed.

Gearbox for tank.
July 2018

We are re-using industrial brushless servo motors, which generally have a lot less torque than your average RC BLDC motor. With these gearboxes, the tank's max speed is just above walking speed, perfect for a following robot.

So we decided to make a tank.
July 2018

Plate aluminum for the side uprights, combined with spacers under compression gave the tank the majority of it's stiffness, even without the top or bottom panels on.

The front of a tank.
July 2018

We thought it would be cool to build a tank. So here we are.

Custom protoboard.
May 2018

Made some custom protoboard, because everything else sucked. We now sell this on Nifty Parts. I used DirtyPCBs again, which gave me very nice boards. I'll have to try out JLCPCB for quicker turnaround. Was going to sell it under "GLK Robotics" but thats just a big meme now.

1983 VW Rabbit.
May 2018

1981 Volkswagon Rabbit. Basically needs to be stripped down to the bare shell. Rust around the subframe mounts. Best way to go about this is to literally build a "rotisserie" dolly to easily access all sides of the car, espeially the underside.

It works! Kind of.

Lixie digit PCBs.
February 2018

PCBs for the Lixie clock project, very nice quality from Dirty PCBs.

Plane Bot!
February 2018

Plane bot! It shoots small balsa planes, gravity-fed-machine-gun style. Built at Think[box] for HackCWRU 2018.
