Cemetech was started in 2000 by Kerm Martian as a prototype group to develop his inventions; it was briefly named CTech before the name Cemetech was chosen. In late 2000 Kerm began to program on Texas Instruments' graphing calculators. This site was originally hosted at http://cemetech.homestead.com. In late 2002 it moved to http://www.geocities.com/kerm_martian/, reachable through the Tokelau-based redirect site http://www.cemetech.tk (now expired). After the site was accidentally deleted, it was recreated at http://www.geocities.com/kermmartian/, still reachable through http://www.cemetech.tk. In July of 2004 a complex forum system was added via InvisionFree, with a member and username system; it was integrated into the Geocities site from here. In the fall of the same year, a new archive system written in Perl was deployed with statistics. Thanks to the efforts of member patl411, March 2005 saw Cemetech move to a better server at http://cemetech.designerz-core.com (no longer accessible). With CGI and PHP access, no ads, and more space and bandwidth than Cemetech previously boasted, this seemed to be the ideal host for Cemetech. The site could be found through the familiar http://www.cemetech.tk. When the site moved to Designerz-Core, the old Invisionfree forum was abandoned, so the forum was recreated with phpBB2.
In June of 2005, Cemetech purchased the domain http://www.cemetech.net, still the main domain for Cemetech. Designerz-Core became increasingly unstable and was eventually abandoned by its owner, so Cemetech followed suit in October of 2005, purchasing a $30/year hosting package from Jatol.com. Jatol providing ample features for Cemetech's rapidly growing needs, including additional databases, email addresses, scripting languages, and space/bandwidth. Jatol remained stable for close to two years, suddenly disappearing in September 2007 among suspicion that its owner either died of cancer or was forced to skip the country by debt. After a week of uncertainty whether data could be rescued, the site was resurrected on SurpassHosting, a host with a five-year positive track record, 200GB of space, and 2TB of monthly bandwidth. On May 30th, 2008, a new visual style was rolled out across Cemetech, and various tweaks were undertaken in the following two weeks to greatly improve functionality over the previous CemetechLite and Cemetech5. The culmination of about two years of work, Cemetech6 was an attempt to freshen Cemetech's look and make navigation more straightforward. Shortly thereafter, we acquired http://cemete.ch for use as an in-house URL shortener.
Since 2008, Cemetech has conslidated its mission to teach programming and provide a safe, friendly venue for collaborating and presenting projects. In the spirit of our current unofficial tagline "Make Cool Things, Teach Cool Stuff" (our official motto is "Leading the Way to the Future"), we have pursued a variety of new avenues for promoting programming education. We attended World Maker Faire in New York City from 2012 to its final show in 2018: over those seven years, a rotating group of Cemetechians showed thousands of students, parents, and hobbyists how they can learn programming with graphing calculators. We have repeatedly attended Texas Instruments' T^3 conferences, showing teachers how they can introduce their students to programming via calculators. The publication of founder Christopher Mitchell's books Programming the TI-83 Plus/TI-84 Plus, Using the TI-83 Plus/TI-84 Plus, and Using the TI-84 Plus, Second Edition have marked new resources available for those looking to go further with their calculators. Finally, we have continued to encourage useful, educational, and fun programs for graphing calculators, including educational programs, games, and Doors CSE for the newer color TI-84 Plus calculators. Into the 2020s and beyond, Cemetech retains a core group of enthusiastic graphing calculator hobbyists, with ancillary interests in programming, hardware hacking, and gaming of many kinds.
