I need to throw together a circuit which uses a pot and triac to provide adjustable control of a heating element rated at 150W 240V AC. Does...
I'm going to build a watercooled PSU. The major heatsinks holding the major semiconductor devices, eg. FETs and double diode packs, will be...
This is a DVR-110D, but you can undoubtedly do something similar with with most drives, especially it's Pioneer relatives. LED's are mounted...
You may remember the modding project i started last year - it's over in the archive section. With the new revisied work logs forum layout, i...
Hi, I'm trying to throw together a circuit for a VCO that will produce an output frequency range from about 10kHz to 1 MHz - with the circuitry...
With this circuit: http://www.interq.or.jp/japan/se-inoue/e_ckt17.htm The output voltage should normally swing between -15V and +15V, or...
So i'm using a LM13600 IC to build voltage controlled high pass and low pass filters. [img] Now, Iabc controls gm, and thus controls the...
Here's the circuit i'm working with: http://us1.webpublications.com.au/static/images/articles/i61/6105_3mg.jpg Now, i was hoping to build it...
I'm wanting to set up a Triac, in my case i have a BT137-600E, to switch a mains 240VAC circuit - specifically a water pump, so it's a reactive...
Remember when i built this? Check the Colossus mk.II project log if you haven't seen it....
[IMG] [IMG] [img] The microcontroller is just a PICAXE-8 i had sitting around, a complex micro isn't needed for this application. with...
[img] Mounting the LCD (difficult to mount because it's too big), it's a permanent part of the front fascia. Using Bondo etc to reshape the...
Are there any differences between the H700B, H700A and H700C besides the front fascia?
http://img.photobucket.com/albums/v476/minerva2/clock.jpg You should be able to work out what it is. I mainly want to know that the logic is...
Most of this stuff has probably already been covered here, but i hope there's something that you find useful. Perhaps this could be added to the...
I've got a dismantled FSP250-60PNA here, anyway there is something that i haven't seen before in it, a great big heavy (bigger than the main...
I would like everyone to get in and contribute to this, and suggest things to cover and improvements. I think we should focus on the Microchip...

[img] [img] [img] As you can see, it can be interfaced with minimum components, no fancy level converter IC's or anything. And no...
The following questions relate to the Genuine Sony (round PCB) LCD's. I want to make the mod compatible with a non-composite sync NVidia card,...
