![]() Given that as far as I can see this project is aimed at possibly non electronics people, hand built strobe lights present a danger. If you can’t, you may get timing variation depending on how many triggers occur between recharges (which since the two are unrelated will vary with time). For a camera a 30 second recharge time isn’t an issue because you typically don’t take photos that fast, for a strobe I expect (but don’t know for sure) you need a quicker recharge cycle to be ready to flash at each trigger. You are likely to find that this doesn’t generate enough current to charge the capacitors in any reasonable time which may be an issue in this application. It has a lot of wires, so here hoping I can get to down to 300V. Note you want to be careful around the 400V output, with the cap that is getting to be enough energy to kill you if you touch it.Įdit: One of these may do as well, somewhat pricey and shipping may be an issue Xenon Flash Tubes XFT-1934 12v Flyback Capacitor charger, HV Flash transformerĪ 12v designed classic Xenon flash Transformer, featuring a Feedback winding for Single-transistor switching.ĮDIT - I just found 1 under High Voltage Transformer, it’s just that it’s 10KV. I’m not sure this oscillator circuit will work (it would need to be in the 50/60hz range to work correctly) but a 555 oscillator at 60hz driving a MOSFET in place of the transistor should work. If you feed the 6V side with 12V the line side should produce 440V. What might work best is a 220volt to 6V power transformer. Note that you need 1kv of isolation which tends to be expensive (a 100V isolation is in the $2/$3 range for 600ohm/8ohm, 1KV isolation is $14 or more). I think the value of the capacitor (and possibly the impedance of the transformer) will control the oscillation frequency of this (it is quite a clever simple oscillator circuit I must admit!). ![]() The transformer you need wants a 80/1 or so ratio to increase 5V to 400V. For 5V in and 50v out you have about a 10/1 turn ratio (which translates approximately to the impedance ratio of 8 ohms to 80 ohms). I’d guess this is an 8 ohm output transformer with an about 80 ohm secondary from the voltage you are seeing. Yes your likely problem is the transformer turns ratio. I did some Googling and it said the only way to work out unknown transformers is test and measure. The only transformers I could find were in old transistor radios, so is the transformer wrong? ![]() Sorry to not offer much help with the circuit. ![]() I also have a list of many other small ones on eBay here they make many other models including variable and higher amperage versions. It is also transformer based so more efficient than the ones above. For $9.99 it is hard to make it cheaper and impossible to make it smaller. You can find other ones in the files section of Neonixe group !forum/neonixie-l Here is a simple one with production files and schematic. I have done a lot of work with Nixie tubes and VFD displays that require high voltages and the simplest HV power supplies are usually inductor-based boot converters. It looks like it makes a half wave input which could be why the output is so low. The magnificent worldview in the story of Gundam spurred, inspired, and moved the imagination and passion of many people involved in the project.ĭreams became a reality, and that reality will give birth to bigger dreams.I must say I don’t really understand how that circuit works. It was as if the process of developing a new Gundam was being carried out all over again.įinally, the frame is completed, and the startup experiment begins! Engineers from various fields have gathered at the Gundam Factory Yokohama to research, analyze, and reconstruct its parts. However, a huge quantity of its parts that seem to be from the Gundam mobile suit has been discovered in Yamashita Pier in Yokohama. It has been said that the Gundam itself was lost after the battle between Earth's humans and spacenoids. The Mobile Suit Gundam from the animation will grace its shores. Hence, Yamashita Pier in Yokohama, the international port city, will witness the harmonious fusion between Gundam, a character attracting much attention from overseas, and Japan's engineering with its top-notch technological capabilities. Its historic buildings and beautiful scenery developed into a captivating cityscape and rich culture. Since the opening of the port, Yokohama has acted as the window for exchanges between Japan and the rest of the world.
