Getting Started With Tiny Whoop

by on Jan.02, 2017, under Electronics, Projects, Tiny Whoop

Tiny Whoop is a tiny FPV (First Person Video/View) quadcopter. If you have been to one of our open house events over the past few months you more than likely have been buzzed by one of these tiny helicopters (Sorry!). Wondered what all the fuss was about? Curious about getting your own Tiny Whoop? Here is our getting started guide to get you in the air with the rest of the makers!

How to get started:

Well, since we are Makers and while you can buy a ready to fly Tiny Whoop (~$275) what’s the fun in that? We’re handy do-it-yourself Makers of course we’ll build our own!

Eachine 010

You can start like many of us did with the cheaper Tiny Whoop Clone: Eachine 010, Eachine TX01 Camera, and a budget FPV Goggles. For around $84 (before tax, shipping) you can be in the air without breaking the bank! You’ll probably want some extra batteries so you can keep flying while recharging dead batteries. Keep in mind that while going this route is cheaper, you will have to wait for the items to ship from the Chinese warehouse (not everything is in stock in the US warehouse).

You can also part out your own flight controller (FC, we recommend the beecore). With an upgraded FC you can use your existing controller/transmitter. You can also upgrade the motors easily and some of our members are experimenting with 3D printing ultra light frames to get even more performance out of their racers.

This is enough to get you in the air and competing with other Tiny Whoop racers at the space. Happy flying, hope to see you at our next Open House Meeting!

Learn to Solder 2 – LCD Backpack

by on Aug.08, 2014, under Electronics, Microcontroller, Projects, Workshops

The attendees of the second in a series of soldering classes built an LCD Backpack, available from Dangerous Prototypes. The LCD screens work over USB or serial connections and can be used for multiple different things. Keep an eye out for our other upcoming classes!

Shapeoko 2

by on Jul.01, 2014, under Arduino Projects, Projects, Woodworking

Our new Shapeoko 2 CNC Mill has been assembled! Thank you to all that pitched in to help put it together. We’ll announce an introductory class on operations when we have some demonstration materials arrive.

If you’d like to learn more about the Shapeoko 2 CNC Mill, more information can be found at Shapeoko.com and purchased at Inventables.com.  Some project ideas to get you started can be found at Project Shapeoko.

Stay tuned for more information!

Halloween Maker Projetct – Lego Minifig Mk. 2

by on Oct.31, 2013, under Arduino Projects, Crafts, Electronics

LegoMk2

This is my LEGO Minifig Head Mk. 2

The original head was starting to get beat up pretty good, so I built a new one. As they are made out of solid Styrofoam, they get pretty warm, so I have a fan system to keep me cool. In the previous version, the fans were activated by a switch in my left LEGO hand and run by a battery pack in my pants pocket. While this worked, it was a chore to get in and out of, and I would usually require assistance getting the wires run and connected.

When I started building Mk. 2, I decided to try to eliminate that issue. I have taken an Arduino Uno and an Arduino Mega 2560 and connected them via two Nordic NRF24L01+ boards. The Uno has 3 switches and is run by a 9V battery. I am currently only using one, the other two are for future plans. When the pin connected to the fan switch goes high, it sends a code (the number 11 in this case) wirelessly to the receiving unit on the Mega. When the Mega receives that code, it closes a relay and starts the fans.

I used Maniacbug’s RF24 Library available on Github – https://github.com/maniacbug/RF24. I found the examples included with the library kind of hard to understand (I’m not a programmer), but I found this example – www.bajdi.com/rf24-library-revisited – and I got my project up and running.

The sketches I used (note, I had a lot of serial.print statements for debugging and I’ve commented most of those out):

For the sending unit:

#include <SPI.h>
#include “nRF24L01.h”
#include “RF24.h”
int msg[1];
RF24 radio(9,10); //define the CE and CSN Pins
const uint64_t pipe = 0xE8E8F0F0E1LL; //Send and receiving units addresses must match
int SW1 = 5;

void setup(void){
Serial.begin(9600);
radio.begin(); // set up the radio
radio.openWritingPipe(pipe);} // Open the radio for sending

void loop(void){
if (digitalRead(SW1) == HIGH){
msg[0] = 11; // Code that is sent to the receiving unit
radio.write(msg, 1); // send code if Pin defined above is HIGH
//  Serial.println(“Switch high”);}}

And for the receiving unit:

#include <SPI.h>
#include “nRF24L01.h”
#include “RF24.h”
int msg[1];
RF24 radio(48,53); //define the CE and CSN Pins
const uint64_t pipe = 0xE8E8F0F0E1LL; //Send and receiving units addresses must match
int relay = 7;

void setup(void){
Serial.begin(9600);
radio.begin();
radio.openReadingPipe(1,pipe);
radio.startListening(); // Open radio in receive mode and start listening
pinMode(relay, OUTPUT);} // Set relay pin to OUTPUT

void loop(void){
if (radio.available()){
// Serial.println(“Radio Available”);
bool done = false;
while (!done){
done = radio.read(msg, 1); // poll Radio
// Serial.println(msg[0]);
if (msg[0] == 11){ // if Radio receives ’11’ from sending unit, set relay pin high
delay(10);
digitalWrite(relay, HIGH);
// Serial.println(“Pin 22 High”);
}
else {
digitalWrite(relay, LOW);
// Serial.println(“Pin 22 Low”);
}
delay(10);}}
else{Serial.println(“No radio available”);}}

Here’s a short video of the system working:

The next plan is to wire a couple of other gadgets to the Mega and I have a relay board I will be using to control them.

Midsouth Makers is getting a dedicated 3D Printer!

by on May.22, 2013, under Arduino, Arduino Projects, News, Projects, Prusa, RepRap, Workshops

If you’ve been following Midsouth Makers you know that we’ve been building. using and tweaking our 3D printers for a while now. Well thanks to a kind donation by LulzBot we now have a dedicated 3D printer at the space for member use! The printer is an AO-101, a MendelMax 1.5 variant.Lulzbot-3D-printer-RT

The AO-101 currently uses 3mm filament and can print in ABS, PLA, Nylon and even Laywoo-D3 wooden filament.  We  have it setup to allow for remote printing on the LAN, using either OctoPrint or Repetier-Server. We recommend Repetier-Server due to it’s stability.

octo-mainrepetier-server

The AO-101 will be using a donated a 1U server as the host computer. Repetier-Server will allow you to load a gcode file and control the printer. We will be exploring webcam functionality for use in monitoring and in generating time-lapse print videos.

We will need the following items to get our new 3D printer setup and functional:

  • Filament- Currently setup for 3mm:
    • ABS
    • PLA
  • Webcam- Logitech C110 or C270 preferred (we’ve already tested and confirmed stability)
  • 120mm silent PC case fan

AO-101 Specifications

  • Build Area – 190mm 200mm 100mm
  • Hot-end – Budaschnozzle 1.2
    • Extrusion temperature range – 180C – 240C
  • Filament- Currently setup for 3mm and can reliably print the following material types:
    • ABS
    • PLA
    • Taulman 618 Nylon
    • Laywoo-D3 Wooden Filament
  • Heated Print Bed (65C-110C)
  • Borosilicate Glass Bed  with PET film on one side for printing with ABS and bare glass on the other side for printing with PLA
  • Integrated Filament Mount for either loose coiled filament or spindles for spooled filament

Current AO-101 Modifications

  • Nozzle Fan for printing in PLA installed but not hooked up
  • RGB LED lighting (white for now)

More information on the new 3D printer can be found in our wiki.

If you’d like to use it, please contact Claudio, Ben, Dan or Cliff- more information will follow. In order to have access to the 3D printer without one of us present you will need to have had verified prior experience with a RepRap 3D printer, or attended an upcoming class on running & troubleshooting 3D printers(TBD) or be able to demonstrate the appropriate knowledge.

Please show our thanks and appreciation to LulzBot and the RepRap community!
