Seeed Studio Fusion Test

Heya everyone!

I do have a favourite manufacturer for pcbs but sometimes its smart to check out the other fabs. I’ll test some manufacturers and write short reviews about them – this time: Seeed Studio Fusion – https://www.seeedstudio.com/fusion_pcb.html

I plan to do something with Nixies in the future but wanted to use a modern driver. After a bit of searching I found this awesome project: https://github.com/dekuNukem/exixe
Damn impressive and even open source! Since pictures are worth a thousand words have a look for the driver pcbs:

 

 

 

 

 

 

 

The edge cuts are clean, no frizzing at all. That’s pretty nice. Unfortunatly Seed puts a production code on the silkcreen. Meh, I really don’t like that.
Looking very closely you’re able to spot the marks of the e-test probes. Pretty impressive, I’ve never seen them before. I wasn’t even sure if my fab does this test.

Following up are some detail shots. The boards are good, but I spotted a small error at the end. Have a look for yourself:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The drills are all centered, the silkscreen seems to be offset by a bit though. Bummer.

Next up is the error I spotted by chance:

 

 

 

 

 

The error is – excuse the pun – microscopic and won’t affect the functionality.
I know it sounds weird, but it’s a bummer you get exactly the amount of pcbs you order.
if you don’t order pcbs often this will most probably sounds weird. But usually you get at least one spare pcb. I like to use them for fitting tests or if something goes wrong while assembling.
Well, thats probably complaining at a high level.

Ah, what’s also pretty nice at Seed is the opportunity to order flex pcbs directly and having your boards plated with hard gold. That’s quite impressive, my fab won’t do that.

Famicom Disk System Dummy Insert

Hey there!

Someone asked my about a scan of the dummy insert for the famicom disk system to protect its drive from dust. The rar file below contains a high res scan of the insert, the *.psd-files are ready to print. The thickness of the insert is about 1.9mm.

Just click the image to download the files:

 

 

 

 

 

 

 

 

Region patch for Live A Live

Just a quick one: I’ve made a patch for Live A Live so it can played on NTSC and PAL systems.

I’m uploading it on this site and to my favourite source for hacks and translations, romhacking.net! 🙂

Patches Live a Live to be played on PAL and NTSC systems.

Works with every version of the game, patched to english or not.

Greetings and love to Maxi and the boys,

You need the beat patcher to patch your rom, which can be found right here.

Have fun!

Comparing solder flux pens

Up until now I have been buying solder flux bottles and put it on the pcb with cotton swabs. Unfortunatly parts of the swabs coma loose and entangle themselves in components. In addition to that it felt kinda wrong to use cotton swabs to put the flux on. That’s why I’m switching to solder pens now – and compare three of them in this post,

These are the pens I bought off ebay. The number in the bottom right corner helps identify them in the upcoming rating:
