    Learning Kicad

    Took me a while to work out why I couldn't find the SWG file to convert in gimp to a JPEG so to post to imgur, yesterday it took me 5 mins....just need to better at organising project folders. anyhow, here is the updated schematic, it passes the electronics rules test :) I've switched the...

    Learning Kicad

    I'll have a nosey thanks. I'll miss stripboard, but it ain't half untidy and brittle in comparison.

    Learning Kicad

    I see, following your leads on entering the forum i find a thread on exactly the issue you have pointed out, thanks! And yes i wish to create a gerber and pc board, would be a useful exercise for me to go through, especially as there is a seemingly endless list of old synth circuits I'd like...

    Learning Kicad

    Thanks Minder, I did get a few errors correlating to them when running an electrical rules check but couldn't understand the meaning of the messages, I will edit as you suggest in my workshop in the morning and run a rules test again. I will check out the Kicad forum also, that could be ideal...

    Learning Kicad

    Hi all I wish to learn how to use Kicad. I have been doing tutorials via Kicad and watched some video tutorials. I have done a few smaller tutorials like learning simple led circuits for example. I would like to see if i can go though the process with a Voltage Controlled PWM circuit I am...

    MFOS Cv and Gate expander module

    Cold solder on out of R13 before R14, D1 and x14 connection was the culprit. Must remember to check soldering more thoroughly when debugging.

    MFOS Cv and Gate expander module

    Drew out the schematic this morning to make notes, got around to testing module B and it suddenly started working. Possibly I hadn't secured a component properly. Anyhow, apologies if anyone had spent time reading this. Concerned the problem may return. But for now it works and have resoldered...

    MFOS Cv and Gate expander module

    Hi all. I can't get a photo of the project to here as I can't get an iphone 4 to talk to windows. So maybe this thread is a non starter? Anyhow, I've taken lot's of readings that may help in fault finding. This is quite a long thread which requires scrolling, maybe there was a better way...

    Dual supply power board +/- 25v

    Hi Loosewire. I'm not the person to help you here, however i'm sure what will be needed is a link to the kit you've bought or a schematic posted here so those with more experience can point you in the right direction. Plus tackling dual power supplies is next on the list for me, so useful for me...

    Analogue Electronics Practical Experiments

    Want to make sounds? Nicolas Collins' book "Handmade Electronic Music: The Art of Hardware Hacking" is a good hands on book that doesn't cost a lot to go through the projects. It has good descriptions as you go to help you build your understanding of what is going in each circuit. It has a list...

    Piezo's. Both running them over distance and pre amps

    Thanks Alec. I'll order the components I need and report back if any problems.

    Piezo's. Both running them over distance and pre amps

    Ok so spent sometime looking at circuits and reading what i think is required. I found the below circuit from Elliott Sound Products....Fig 10 in this link. http://sound.whsites.net/articles/high-z.html Is this a suitable circuit?

    Piezo's. Both running them over distance and pre amps

    Thanks Alec, off to look at Piezo Pre Amp circuits now and the cables you suggest. Dunno why I didn't think about screened cable, doh!!!!! just used whatever I had lying around at the length needed today.

    Piezo's. Both running them over distance and pre amps

    Hey all. Today I was trying to help an artist with an installation. They want to amplify water dripping on metal objects, I tested today attaching piezo discs on to them (water proofed) with simply putting a 100nf capacitor across it's contacts then running them around 15 meters each to a...

    [SIMPLE CIRCUIT HELP/ANALYSIS] LEDs driven by GameBoy sound

    Are you copying the circuit from somewhere? Can you post it on here? A brief look at the circuit; Others will tell me if i'm wrong, I think you should have each of your LED's (load) between your + supply and the collector of the BC337, with an appropriate (current limiting) resistor. Then the...

    Painting own 6mm guitar/instrument cable 6mm

    Wow, what a great reply. Thanks! Just waiting for my cable to arrive and I'll endeavor to replicate your steps above, and gonna be much cheaper than my initial plan! which is always a bonus! plus I'm really intrigued to see how the extra reinforcement on the ends of the cables/jacks pans out, I...

    Painting own 6mm guitar/instrument cable 6mm

    Hey 73's de Edd, I've utilised this a little, definitely worth further consideration as would be much easier. I'll try it out tomorrow more and see it is a viable solution. Thanks.

    Make experiments safer, my workshop and concepts relevant in my opinion

    There is a project log section of this forum, where this might find a better home, not that it's not ok here, just in the project log you can keep your 'project/workshop endeavors updated', and generally you might find people who follow your work and offer input at points along the way. I keep...

    Painting own 6mm guitar/instrument cable 6mm

    Thanks Dave It's two fold, I can buy a bulk load of black cable much cheaper than of separate colours, I would like to have a more varied range of colour's to choose from when patching my synthesiser. Plus when I start adding motors to my synthesiser circuits I'll need to be able to...
