Another USB-C upgrade

USB-C conversions are becoming a bit of a thing around here. We repaired a faulty work light earlier this year, and we took the opportunity to upgrade the charging socket to USB-C. A few other items have had the same treatment over the last few months. This latest one is an old-school light box for viewing film negatives and slides. We’re still keen on our film photography at TOG, and we still have all of our dark room equipment. 

As-built, this particular light box came with with a foot-long fluorescent tube. Inside, there is a driver PCB for the tube, and a 6x D-cell battery compartment. It also has a 3.5mm power input socket if you want to run it from some kind of adapter.  

The small driver PCB inside takes the ~9V battery voltage and bumps it up to the high voltage required to to run the fluorescent tube. The switching transistor on the driver has already failed once in the past, and its heat sink gets very hot during operation. Probably not a very optimal design or power efficient.

A bit of work with a Dremel and we have a nice oval hole for the new USB-C socket. A few touches with a soldering iron to melt the plastic, and the socket is now joined firmly to the case. The intention was to feed in 5v, and then bump it up to something closer to 12v to charge the batteries via a current limiting resistor. A cheap voltage converter sourced from the usual websites would look after that.

That was the intended upgrade, but a bit of feature creep came along last night. We thought that it would be nice to replace the fluorescent lamp with a more power efficient LED one. This would also allow us to eliminate that iffy driver PCB. Rummaging around the space, an old emergency light fitting had a nice LED strip ripe for harvesting. Check back in with us over the next while to see the finished article. If you have anything that you think might benefit from a USB-C upgrade, drop in to our regular Monday and Tuesday open nights.

What Can You Work On? Anything goes! This is an open hackathon where you can:

  • Squash that annoying bug in your open-source code.
  • Wrap up a writing or design piece.
  • Complete an electronics kit gathering dust.
  • Revamp, repair, or refine something you’ve been meaning to finish.

What Should You Bring?

  • Whatever tools and materials you need for your project.

Pizza Oven Overhaul

From almost the very beginnings of TOG, our monthly Saturday evening Open Social has been a constant fixture in our calendar. At our Open Social in January 2015, a quick hack over the previous few weeks at making a brick pizza oven from a stack of red bricks and some bits of angle iron turned out to be an unexpected instant hit. Our Open Social was changed forever, and has become as much of an outdoor event as an indoor one, irrespective of the season.

We were blessed in TOG 2.0 (Chancery Lane) to have our own private yard where we could leave the oven permanently. Fast forward to TOG 3.0 (Blackpitts) where there was a large outdoor car park, but we couldn’t leave stuff out there permanently. The solution was to create a mobile pizza oven that we could wheel in and out as required. Using a gym ball as a mould, we made our current mobile pizza oven.

After 7 years of hard use, it was time for a bit of well deserved maintenance. The top was removed and the base refilled and leveled with fresh perlite. New dedicated fire bricks instead of red bricks were laid out for the base. Unlike the previous red bricks, these fire bricks are all identical in dimensions and have now made a super flat cooking surface. The inside of the dome got some re-pointing with new red pottery clay.

At our combined Open Social and 16th birthday party last week, the newly refurbished oven was put to the test. The pizzas were fabulous. Thanks to Conor for making the dough! Being a maker space, you get to prepare and cook your own pizza. We even have peels that we made ourselves. We are a maker space after all! To see the oven in action and to have a go yourself, drop into any of our Open Socials.
