Nixie clock sets time from internet, encased in concrete

Chankster built a Nixie clock that uses the NTP protocol to set the time over an internet connection. For a final touch, it was encased in concrete. Time is synchronized using the network time protocol. An ATmega keeps the time, controls the nixie tubes, and connects to the internet via the popular ENC28J60 Ethernet IC. […]

ATX Breakout board free PCB build

Schazamp built an ATX Breakout board free PCB. The ATX breakout board routes the -12, 3.3, 5 and 12 volt ATX outputs to screw terminals, each protected by a 1.25 amp resettable polyfuse. Here’s my ATX breakout board assembly. I am not happy with the binding posts, but I had them from another project, and couldn’t […]

Playing with ATX Breakout Board in KiCAD

Over the last week we re-visioned the ATX power supply breakout board in KiCAD, free of the confines of Eagle’s 100mm by 80mm cell. We chose the ATX board because it’s already at the limit of the free version of eagle, and it’s filled with big connectors that can’t be miniaturized. This version builds on […]

Testing the efficiency of Nixie power supplies

Gelbanana tested 3 HV SMPS Nixie power supplies for their efficiency. The tested ICs were the always popular NE555 timer, the MC34063 buck/boost controller, and the MAX1771 boost controller. The MAX1771 was the most efficient, but it also costs 10x more than the other two ICs tested.  Table with the results of the test can […]

Workshop Update for September 11th, 2012

Today we built up 14 Nixie Display boards, trying to figure out how to connect the sockets without stripping 240 individual 3″ wires. We also started working on some illustrations for the OHS 2012 USB presentation. We made some models, and are in the process of rendering them. You can check out a preview video […]

Big box of parts for the US

A few months ago a big traveling part box started in the forum. It’s currently working its way through Europe to India. To cut down the costs of intercontinental shipping, several US members got together and started one too. The picture above is just one member’s contribution, there’s lots of other good stuff inside. It’s […]
