Gorgar: We Finally Fixed Him!

If you remember, some of my earliest posts are about Gorgar. My dad picked up this pinball machine for next to nothing, rescuing it from the scrap yard. During this winter break, we moved the machine over to my dad’s house, in order to have more room to work on it. Today, we made a breakthrough: we fixed the biggest issue, and now it is 99% functional (all we need is a solenoid coil to fix the center drop targets.)

Read on for a timeline detailing the work done on this machine since we received it.

Home Device Repair

Hello again, it has been a little bit. College has picked up, and as I am moving in a little over a week, most of my projects have been packed. However, I’ve worked on a few things in the past little while.

Remember my half-repaired LCD monitor? Well recently I obtained yet another defective LCD monitor. Symptoms: no power, no lights, no noise. I may or may not post photos about this one, because I did all repairs without taking photos, and it was a pain to take it apart, and I wish not to do so again, hehe. Basically, the cause was 4 blown caps in on the circuit board, which I’ve replaced and it now functions fully, aside from a little squealing when in stand-by or turned off (I believe due to a capacitor that started blowing but that I measured to be within proper values.)

A few months ago, however, I did document a repair project I undertook. I have two home theatre amps at home that I’ve had problems with. At one point, both had stopped functioning properly. So, naturally, I decided to set to fixing them.

DIY Multimeter: Complete!

As mentioned in a previous posting, for Christmas, I received an Assemble-it-yourself Digital Multimeter Kit. Awesome. So, for the last week or two I’ve been building it, section at a time, till tonight, where I found myself in need of doing a calming activity. What is more calming then sitting down and soldering for 2 hours, while listening to Paramore’s discography using my DIY FM Transmitter to broadcast to my DIY AM/FM Radio?

Anyway… This is what it looks like, finished:

DMM: Mr Blurrycam

Sorry about the Mr. Blurrycam shot. Darn flash. I’ll have a clearer shot after the break, along with more details on the functions.
