Nice. How soon do you think your ready to roll with these? I am still saving up for my wilba seq panel and case. I would love to get one but have to wait awhile. I really like the single ac adapter. You gotta show us noobs how to make good ps circuits for sid and fm.

I can be ready to roll as soon as I know people want this kit and that the first batch of 25 will be sold... :)

Is it mesh holes because of internal heat? Do you think the elements would be an issue?

The voltage regulators and heatsinks must dissipate quite a bit of heat when passing 300mA of current... it's a common issue with building a MIDIbox SID - how to get 9V and 5V supplies from a single power input. This design uses a 7809 to regulate 9V from the input power, then passes 9V DC through two power diodes before supplying a 7805 to regulate the 5V. There's a constant load of more than 300mA on the 5V supply (each SID is 100mA each!) so that does cause the heatsinks to get hot. Due to the compact design, lots of ventilation was added so there's no issues with heat building up inside the case.

This would be ideal I have 2 spare sids. Please count me in. Thanks!

Can you show us a video demo of your sammich in action?

Maybe TK will do one when he gets his prototype. ;)

Kit for me! Excellent job Wilba! This thing looks freaking awesome and will be great to have while I am finishing up my MB-6582 (still having trouble with the CS to mainboard wiring - wires keep getting pulled off :/). That and it looks sexah!

Oh quick question - is there enough room for heatsinks on those SIDs? Similar to the ones used by some peeps who've built an MB-6852? I couldn't tell from the photos, but it looks like a heatsink might be a tight fit. Thought I'd check anyway :)

Damnit I can't wait for kits! w00t!

Thats friggin awesome!
You never know what to expect is coming round the corner from Wilba!

Btw, why does the logo have nILS name written all over it? ;)

I have the ones that fussylizard used and will try them out... the spacing between the SIDs is identical to MB-6582 but I'm not sure about the clearance with the control surface PCB above it. IMHO you don't need heatsinks for 6582A and there's enough ventilation to keep them from running hot.

nILS did the base PCB layout and designed the logo, however, he will claim he was just my slave and did whatever I told him to do.

It's funny that use of the DIN 1451 font makes things look like nILS did it... :)

Hi, that looks really cool.

Have you come across any alternatives to Ponoko as I live in the UK and the shipping is astronomical!
Cheers

put me down as number 25 on the list for a full kit (incl. sids) :D

Unfortunately not... I'm sort of lucky that shipping from the Ponoko hub in NZ to Australia is reasonable and keeps the cost of the case down.

That is very cool compact design Wilba/Nils. I`m not sure I get you right... will it be sold only as a kit with/without SID, or you will sell just PCBs too?

Can I ask why people would want just the PCB when I'm also selling all the parts at bulk order prices?

You can, but I'll go on record as saying I'd prefer a kit :) In fact, I'd probably order a full kit even if I wanted to make customizations since that would seem to be a lot easier that way.

If the costs of the kit are marginal, I would say it'd be easier for everyone only to do the kits? But that's just my thought. I've never done a bulk order or anything, but, damn, they look like a lot of work. Huge thanks to everyone who puts those together!

Well, because of the US$200-US$250. Don`t get me wrong. I don`t think it is expensive, but I already have all the parts to build it and laser cutter at hand for making custom case at low price. I could make it pretty cheap if I can buy just PCBs. If you sell it just as a kit, I understand. No problem.
