Come winter time, the hackerspace can get kind of cold. And in the summer, it can get darn hot! To give members a heads up of the current temperature in the ‘space before making the journey out here, we created a web-enabled temperature/humidity sensor.
The main device is an ESP8266 which reads a DHT-22 sensor. The temperature and humidity information is sent up to thingspeak.com. From there, a quick PHP script in our WordPress Widgets section can read and display the current temperature on the website. Since the DHT-22 can also do humidity, we opted for displaying that as well. Visiting the thingspeak page shows a graph of historical data.
S.O.S. : “Save Our Space”
IMPORTANT MESSAGE TO ALL MEMBERS of the CT Hackerspace Community
Your community is in real danger of closing.
After reviewing projected budget numbers, there will be a financial deficit by the end of the year.
Because of increasing expenses, and not enough income being derived from monthly membership dues (and income from workshops), CT Hackerspace has been running at a small, but not insignificant loss, for about the past year.
Action must be taken now or difficult decisions will need to be made about the future of the space from mandatory dues increase or up to the worst case, closing the space.
Help support our future builders, leaders, and engineers at FIRST Team 237’s Ziti Dinner at Union Congregational Church, Buckingham Street, Oakville, Connecticut 5 PM – 8 PM tonight. Continue reading
Bill and JR celebrate the two spaces working together.
When fellow makerspace MakeHaven started in New Haven, they inherited a laser cutter which had been abandoned. The model is the Universal Laser System M300 (50 watt). Make Haven now has sights on a new project: Two used Epologs in better condition. The m300 was then mothballed. MakeHaven’s first thought was that they could scrap it for parts or sell on ebay, but they decided they would rather see another space in Connecticut use it if there was interest. CT Hackerspace has taken on the challenge, and now will be actively pursuing rebuilding the broken laser cutter for use here at our space! Continue reading
Today we had a herd of Elephants running around here at CTH. They are 3D printed and part of Dmitriy’s most recent project, a three dimensional zoetrope. He started by modeling 10 different elephants, each representing one-tenth of a stride. Each model is printed and attached to a spinning disk powered by a stepper motor. A bank of LEDs flash 10 times per revolution resulting in the illusion that the elephants are running. The contraption is powered by an old ATX power supply, 12v going to the stepper motor and 5v for the logic. An Arduino controls the stepper motor and times the LEDs.
Have you ever wanted to learn how to use a Milling Machine? At our most recent “Intro to the CTH Workshop“, Matt gave a great overview of our Bridgeport milling machine. Attendees learned the specific uses for drilling, milling and boring as well as how to change the tool in the machine. Matt also went over using an edge finder and the DRO (digital readout) for super accurate positioning. Now, no piece of metal is safe from modification into some cool project. Each “Intro to the CTH Workshop” will focus on a different piece of equipment. Future workshops will be listed on MeetUp.
OCTOBER 3rd 2015: CT Hackerspace will be on site for be part of the inaugural Greater Hartford Mini Maker Faire. Enjoy the day and spend some time at our booth to help promote the our community. The Faire has already had 700 people sign up on their website and they anticipate at least 700 more walk-ins, so get ready.
Using a Lathe / Woodturning : Bowl Making
In this full day workshop, you will learn basic bowl making on the lathe, going from a rough cut piece of wood to creating a finished bowl.
October 10th, 2015 1:00PM – Cost: $45 – 2hrs
Interested in the Internet of Things ( IOT ) you have been hearing so much about?
Want to publish values from a sensor to the Internet or your LAN?
Interested in Low Cost Microcontrollers that have built in Networking?
If you answered yes to any of these questions, this work shop is for you. This workshop will introduce you to the ESP8266 family of Wifi capable Microcontrollers that are more powerful than an Arduino yet can be purchased for less than $5.
Felt left back in this data-centric era?
Have problems describing needed reports to colleagues?
Sean N. Henderson will be helping beginners understand how to get better results at work by understanding SQL – a language used to retrieve portions of data from a database. Sean is a software developer and IT professional with over two decades experience working with databases and happy to share his knowledge and expertise in this area with the CT Hackerspace community.
