An ongoing project, this homemade 6×17 panoramic camera is not something that will win a beauty contest but the photos it takes are amazing! The body is mostly built out of 2mm aircraft grade aluminum and the lens is a wide Caltar W-II 90mm, something that would normally be on a 4×5 camera. He does a great image comparison between the results from this camera and a Nikon D200 to show the leap in quality. I love pages like this, the inspiration they give make browsing the web well worth it.

… Well a bunch of multimeters to be exact. I found this in my mailbox today:
Your readers are sure to get a kick out of my latest clock project. The clock consists of three multimeters, the first meter displays hours, the second displays minutes and the last displays seconds. A 16F628A PIC microcontroller keeps track of time and outputs a calculated current to each meter to display the current time.
Heck yeah, that’s pretty darn cool!
I thought it would be cool to have a clock that looks like an old Simpson 260 multimeter. The clock consists of three multimeters, the first meter displays hours, the second displays minutes and the last displays seconds.

A clever hack that combines a Mac Classic with a brand spanking new Apple iPad. No, the Mac Classic no longer works after this hack but you have to admit that it’s better than leaving to molder on a closet shelf somewhere.

Ah, the Marx generator. I have fond and not so fond memories of building my first one. It worked very well, I knew this because of the sort of out of body feeling I had when I got zapped by it. Anyway, it works by charging up a bank of capacitors in parallel and then are discharged in series. It will turn a few wimpy volts into something that will quite literally take your breath away. This site has a nice semi tutorial on how one is built. Go have a read and start scrounging in your junk box for some parts (mind you, keep a hand in your pocket to avoid making a dead short across your chest and through your heart. It’s not a sure thing but it helps)

I went to the bi-monthly hackerspace meeting last night. They had a guy there giving a talk about an open source 3D printer that he and his company is working on. I posted photos of it on Flickr. The thing is called ‘Cube.ly‘ and will, once finished, print 10cc of volume per hour, cost under $1000, takes a weekend to build, and is made of off the shelf parts. The frame is made of this stuff called ‘80/20′, think adult sized Erector set and the other bits like motors are available from McMaster-Carr or the guys that build the Makerbot (electronics).
Another very cool clock kit to lust after. I swear, if I had my way my room would look like Doc Brown lived in it…
The second clock kit from ladyada & Adafruit Industries, we present MONOCHRON!
We wanted to make a clock that was ultra-hackable, from adding a seperate battery-backed RTC to desiging the enclosure so you could program the clock once its assembled
- 128×64 LCD (KS0108) – we special-ordered the black and white display
- ATmega328 processor (we even stuck an ‘arduino’ stk500 bootloader on there too)
- Laser cut enclosure in black acrylic
- Beeping/blinking alarm with 10 minute snooze
- Battery backed-up real time clock (DS1307) keeps time even when power is lost for years
- European/US 12 or 24 hour time display as well as date
- Completely open source hardware, all firmware, layout and CAD files are yours to mess with
- Plenty of space for mods, a prototyping area for soldering stuff in
- Soothing animation of retro arcade style table-tennis for two
