Pictures of failed bow limbs


These were limbs that i hand crafted but unfortunately due to the nature of bending PVC sometimes the results are the  most desired; however, the process itself is relatively easy, cheap, and replicated easily.

-Draft- Construction videos of the bow limbs

So these are some recordings of me making the bow limbs these are the -draft- videos ill have a playlist of the better version up very soon. Below is a link to my Youtube channel where i posted the current videos up. Once again i will have more coming.

Getting Supplies and Testing Materials

Hey all, Ethan here.

Our group has put in a request for a number of items that should be useful or necessairy for the crossbow, or rather entirely useful, if not fully utilized all at once.

Spring Steel Standard Key Stock, 1/8" x 1/8", 12" Length
Impact-Resistant Polycarbonate Sheet, 1/4" Thick, 12" x 12", Clear
Motor Shield v2.3
8 x AA battery holder
Micro Switch w/ Roller Lever - Three Terminal
Stepper motor - NEMA-17 size - 200 steps/rev, 12V 350mA
Micro Servo - High Torque Metal Gear
DC Barrel Jack Adapter - Breadboard Compatible
DC Barrel Jack Plug - Male

 Hopefully out request clears and we are able to get covered for all the above under the Dean's Challenge, let alone get cleared on the request.

The Polycarbonate is for constructing gears out of for the gearbox that the stepper motor with drive, and the servo is to be able to push the motor into place and take it out before firing. The key stock will be for the gear axles, with the hope that they will better withstand any torque that is acted upon them.

The motor shield is to run the servo and stepper motor, and the battery pack will be for powering the motors directly rather than through the Arduino.

The DC parts are for if we are to get a 12V rechargeable battery pack, which would allow us to recharge the battery within the crossbow rather than having to open up and remove it.

With the remaining funds, we still have some wiggle room, which is good, considering we still plan on getting the following items:

Scheduled 30 PVC Pipe (Diameter varying)
1/8 in Nylon Cord
Fiberglass Stakes

We do have access to some of these already, but at least we know we have funds if we ever need more.

The PVC and Fiberglass Stakes are for the crossbow arms, and the cord will be for the drawstring.

Brendan got to making a mock up of what he envisions the crossbow will look like once made to full scale:


We will be testing the PVC to find the optimal draw length, so 2 ft. may be a bit much, but we won't know until we do tests.

That's all for now. Hope to post more soon.

Regards,

Ethan

Schedulin'

For the sake of keeping our group up to date on each other and where we might be in the hours of the day, we have decided to post our school schedules.

Project ADC: The Introduction

Hello there!

We are Project ADC, a group with the goal of making a LARP (That's Live Action Role Play) crossbow, capable of having a draw strength of 25-30 lbs, as well as being automatically drawn by an Arduino run gear system, with the possibility of a variable draw strength system do dial in draw strengths between twenty and thirty lbs.

Arduino will hopefully be able to bring this project to life, as it has for countless others, like these:

Real Tracking and Shooting Portal Turret:


Gauss Rifle (6 Stage Coilgun):


Arduino GPS Board:



 We hope to post more about this project as we go, but like, not cause its for a grade or anything. Clearly we just love to share our information with the world; Our totally not graded or dependent on passing the class information.

Regards,

E. Weigold
