Makerfaire 2013 Part 1

Well, this year’s makerfaire was more awesome than last year’s, the only thing I didnt see there was the robots in the streets, like metro man and his bot, and the flying car from last year. I believe it was GM that had one last year.

This year tho, they had a ton more stuff there, and even more people there. There was alot more speakers and interesting people there than there was last year. I also got to meet Eben Upton, the head of the Raspberry Pi Foundation. http://www.raspberrypi.org

I also got to show eben my netbook, so Im all happy about that, and I got to talk to the head troubleshooting and head of the company from printrbot and got it all sorted out, I just emailed them and it should all be worked out within a few days. 😀

Anyways, here’s what you’ve probably been waiting for, or at least part 1 of them, there’s too many pics for one post:

Here is my pics from my cell phone from this year.

Update

Well, tomorrow we leave for world makerfaire in new york. I havnt really posted much lately due to the fact that Ive been working on my new printer because of the printrbot jr’s printrboard (controller board) died. Ive been trying to get ahold of someone at printrbot to see if I can get a replacement, but so far, I havnt been able to get ahold of anyone through support tickets, or through private messages on the forums. I also tried contacting the head of printrbot on twitter because most people have said they had better luck of getting a response back from them on there, but it seemed like he just ignored the question. Maybe Im not sending the messages right or something on there, but it’s always worked with everyone else Ive ever tried it with. It’s waay too much of an expensive part to have to just toss the old one and get a new one when it’s not very old at all. (around 130-140 dollars for the board)

So Im just trying to figure out how to get the printrbot jr up and running again, and hoping I can get ahold of them to see if I can just get a replacement. Ive heard that thier warantee stuff is really good if you need something replaced, but I guess just getting ahold of them is the hardest part.

Ive decided not to go with the printrboard, sanguino, or ramps for my new printer, and instead, go for a gen7 board because of multiple reasons. Mainly, I just wanted to build the whole printer from scratch excluding the motors and maybe hotend, and I wanted to be able to really really customize the firmware and hardware myself for everything.

Ive decided on the gen7 1.4.1 rather than the 1.5 due to the fact that 1.5 has the usb chip built in, and eventually I want to do away with the usb chip entirely and use a level translator to convert the 3v signals to 5v and vise versa for hooking it directly up to the serial port on the raspberry pi, and just build the raspberry pi into the printer itself so it would have an all in one printer that I can just take with me and not have to worry about plugging in a bunch of power cords to get it to run. Just run the 5v from a pc power supply, and that’s all you need.

Like I said before, makerfaire is in two days, and Im already packed and ready to go, and will upload alot of pics from there. I saw that this year, eben upton from raspberry pi foundation will be there also showing off some of thier new hardware, and Im hoping that I’ll be able to get a pic or two with him also. Who knows, maybe Ill be able to show off that little hacked netbook running as a raspberry pi also 😛

Im hoping that the printrbot guys will be up there and see if I can just talk directly to them to get all of this sorted out. It’s been around a week since I sent in the support tickets and still havnt gotten a reply or anything from anyone, so maybe Ill just be able to ask up there. There’s still a good amount of parts needed to be printed out for my prusa, and cant, also I have a few other people wanting stuff printed also, so need to get it up and running asap.

Also, if anyone reads this site and knows the answer to this question, I’ll ask it here:

Ive seen people saying that they get disconnects using the ft232 chips and 3d printers due to the latency, but I also see other people using attiny chips or other usb-ttl converter chips, and I was wondering if the other chips have that issue, or if it’s just ft232 related. I only ask because for testing everything and getting everything set up, I wanted to use a pl2303x based converter that Im planning on making from an old dialup modem that I tore apart ages ago. Always better to repurpose something than toss it if you know you can use it for something. 😛

Program an Arduino using your sound card

audioino_programming_arduino_with_sound

[Chris] wrote us to share a neat technique he has been using to program the Arduinos he uses in his projects. He likes to build bare bones Arduino clones rather than sacrifice full dev boards, and instead of programming them via traditional means, he is using his computer’s sound card.

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack. After burning a special audio bootloader to the chip, he can connect the Arduino directly into his computer’s speaker port for programming.

Once the microcontroller is connected to his computer, he runs the IDE-generated hex file through a Java app he created, which converts the data into a WAV file. With the Arduino put into programming mode, he simply plays the WAV file with an audio player…
