Mostly Printed CNC (MP-CNC)

Having a CNC machine to cut panels for projects has been a wish for a while. Then I found this awesome project: Mostly Printed CNC (www.vicious1.com). As the name says, most parts are 3D printed and the non-printed parts are easily accessible. The controller is a RAMPs 1.4 board with Arduino Mega, easy to find cheap online. I used the Marlin firmware because it’s the same as both my 3D printers. After destroying my Mendel i2 trying a new printing surface I had spent many hours printing the parts on my Solidoodle2 with a printing volume 6″ x 6″ x Continue Reading →

Samsung Smart Aircon and MRTG

We’ve had 4 Samsung Smart air conditioners for a few years and every once and a while I revisit trying to automate them using scripts and a like. This time I was successfull using perl scripts written/edited by Daniel (CloCkWeRX) and Shannon (freman) to deal with the transmission protocol and token management – I personally would’ve never been able to work it out – so thanks and full credit to them. To start with, you have to discover then register the aircons to get a token for each, to discover them you can use this script get_samsung.pl, which was obtained Continue Reading →

Domain transferal

Yeah it’s that time again, I’ve had to change domain hosting companies again, please bare with me, it’s complete, although DNS is still flapping from the old to the new provider every couple of seconds – so results may be mixed. UPDATE DNS has been working fine for a few weeks – Transfer complete! To my old provider – your helpdesk is shamefully un-trained. UPDATE 16-12-2015 It appears that there are a few files that didn’t transfer during the last backup I made before migrating servers – mostly zip files, so some attachments may be missing. I’ll be updating these Continue Reading →

Hot End Failure

While trying to print out the LCD mount for the “Internet Radio” project. I returned later to check the progress on the print after it finally starting due to temperature issues. I found this: The temperature sensor had pulled free and had a piece of plastic lodged between it and the hot end. When I removed the hot end for inspection, the sensor broke apart. Clearly it was time to replace the entire hot end. It has served me well and is only the second one used in my Prusa Mendel i2. The new hot end is 95% metal with Continue Reading →

Smoker/Kettle BBQ Controller

After tasting some awesome BBQ offered in the US, I wanted to try making it myself. I’ve tried to use a gas BBQ, but it always turned out dry and tough. I moved to a charcoal kettle grill and wanted to be able to have more control of the temperature. Options: manual control – Continuously checking the temperature on the gauge that came with the BBQ. Buying a professional smoker – big $$. Make my own controller – When researching I found a professional BBQ team that used a controller that adjusted the temperature using a fan and temperature probes. Continue Reading →

Bakelite Internet Radio

NOTE: If your a vintage radio purest you may want to look away now, as I never had any intention of restoring the radio back to its original glory due to the damage of the insides and the custom speaker. I wanted to give it a fresh lease of life while hopefully doing it justice. The radio is a Stromberg Carlson Ovaltone (model number:5A29), manufactured around 1949. I was unable to find much information on it, and I’d guessed the model number by comparing it against other online pictures. What I’m going to do is make it into an internet Continue Reading →

Netgear EX6200

I went against my hatred for Netgear and bought an EX6200 as a replacement for the wireless access points I’ve been using. Having not bought any wireless gear for a while, I figured might as well check out 802.11AC equipment. After the purchase, I found the hardware to be well over spec: dual core 800Mhz processor, 128MB RAM, but the firmware was crippled by rubbish “end-user friendly” features, and only allowed external connections from the existing LAN via wireless sources. To Netgears credit, it does state the following in the manual: “Can I plug it directly to my main wireless Continue Reading →

Prusa Mendel i2 to CNC Engraver Conversion – In progress

I’ve been checking out parts lists and prices for DIY CNC routers. After some research, I’ve decided to convert my Prusa Mendel i2 to a small, very cheap CNC engraver, So I could get a feel for them and work out if it would be worth making a full size one. Below is what I had to work with. You may notice the extra braces on the top corners – the green parts. There is other extra supports on the board it’s screwed on to, to make it more ridged than usual. I found a few mounts on thingyverse, but Continue Reading →

Cheap Pickups – Box of Server Parts

Found a shoe box sized box of random PC parts for $10. I wasn’t able to see the entire contents, but was assured it was all related. I’m always looking for cheap cables and assortment. Cut the tape on the box when I got home and found: 1x Supermicro X7SBE motherboard. 8GB of DDR2/677mhz ECC RAM (2GB sticks). 1x  Dedicated IPMI card for the board. 1x Quad core Xeon X3360 @ 2.83GHz. 1x rear Double USB motherboard extender. I also bought from the same seller for an extra $10:  Low profile dual 36pin SAS card – cant find the model Continue Reading →

Ambient Light with Arduino and WS2811

The ambient lighting on this project turned out so well I wanted to try it on a normal TV. When making the back light for a second time, I used an Arduino Mini Pro with mini USB port. I did find a small hiccup, the baud rate needed to be changed to 115200 most likely due to limitations in the USB to serial chipset on the Mini Pro (CH-340). The refresh rates are still very good. I am also using less LEDs which may contribute:         “device” : { “name”       : “MyPi”, “type”       : “adalight”, “output”     : “/dev/ttyUSB0”, “rate”       : Continue Reading →
