Re: Uzebox DTV
PCB etched, cut and drilled.
Next up tin plating, mechanical vias and then solder all the components.
Not feeling great today, but hopefully can stay out of the bathroom long enough to get it together.

Wow, didn't knew self etched PCBs could look so good...it's gorgeous!
Sorry to hear about that pal, you take medications that makes you sick?Not feeling great today, but hopefully can stay out of the bathroom long enough to get it together.

Re: Uzebox DTV
Thank you for the compliment. However it's hardly my best work. I can do traces/spaces about half that size across a whole board if I take care.uze6666 wrote:Wow, didn't knew self etched PCBs could look so good...it's gorgeous!
I'll post some more piccies of the boards below.
I take medications to stop me being sick, but they make me tired and fuzzy in the head so I don't take them so often and just deal with the very frequent pit stops.uze6666 wrote:Sorry to hear about that pal, you take medications that makes you sick?

Re: Uzebox DTV
The three photos above are of the PCB after the tinning process. A whole shot of the front and of the back. Then there is a close up of the position where one of the 4021 CMOS shift registers is that emulates a SNES controller.
The below three photos are
1, The back of the case showing the slot cut for the ISP header and the hole drilled for the recessed reset button.
2, The top of the case showing the 3.5mm socket that carries 5v, audio and video AND the slot cut for the micro SD card.
3, A shot of the PCB with the two sockets soldered on. Yay they fit first go

Re: Uzebox DTV
Finally have myself a real uzebox
bit of excitement to start with the picture was all purple. Did some continuity testing, checked the signals on a scope. Then realised "AH port c - JTAG"

Re: Uzebox DTV
Wow, this looks great!
This really gets me in the mood to create a design on my own.
Did you design the packages for the buttons yourself or did you find a library for them?

Re: Uzebox DTV
That is pretty damn sweet. Those are some tiny resistors on there. I've soldered some surface mount chips without a soldering station but I don't know if my eyesight is good enough for the resistors.
You rocked that pcb like a boss. Was that a laser printer transfer?

Re: Uzebox DTV
Epic work there.
Laundry list of questions here: Is the design basically finalized, what brand of controller does the board fit, do you have eagle/gerbers, and are you planning to have a short run of PCBs made? Reason is I want one now and someone might as well order 50(~$80 heretotal if the estimate is right?) and sell the rest at cost. Maybe the price of a case of beer for assembled Controllers look to be about $150 for 50 controllers if you wanted to go the whole package route.
Edit-25 total might be more reasonable, and assembling that looks like a nightmare

I cheated. I actually used a 1612 resistor as the footprint, and the button is drawn on the copper layer. For sending off to a board house I will have to make a real footprint.
The resistors are all 0603. There are some 0805 capacitors and THREE 0402 capacitors. Here is a photo showing all three sizes together. The two resistors in the background are 0603, in the foreground are an 0805 inductor and a 0402 capacitor. I try my hardest to avoid components smaller than 0402. Everything on the board was soldered with an iron apart from the SD socket and the crystal which I hot air reflowed.hpglow wrote:That is pretty damn sweet. Those are some tiny resistors on there.

The PCB is printed with an inkjet onto special transparency film (about $1 a sheet) then UV exposure for the PCB. Finally plated with "cool amp" silver. The traces here are 10thou. I can do 6 thou myself, but wanted to make the PCB big and easy for other people to make if they wanted.
The design is prototype ONE. I have a few changes I would make if I am going to do another at home for myself. There are a LOT of changes to make if I am going to do a small production run.D3thAdd3r wrote:Epic work there.

I will release the gEDA files and gerbers after I have fixed some bugs. They are not mistakes as such, just annoyances that make assembly harder.
I am planing on doing a kickstarter or indigogo campaign with a "successfully funded" target of 10 units. I am going to keep some myself to give away to "novices" in next years UCC (if that happens).
The BOM from digikey + PCB + case comes in at $36 (10up). I was going to price them on kickstarter at $50 ish. That way if 10 sell I am sweet. If 50 sell and I have to pay for someone else to assemble them, I am still not out of pocket. If 500 sell I will be into real profit and be able to afford a new computer to do my game development on

Re: Uzebox DTV
Wunderbar! I'm in too for 2 or 3 units! The kickstarter is a great idea, I'll back you up for sure (would they be assembled?).
ps: There's a spot on the controller for a logo....what about a uzebox logo sticker in there? I'd gladly contribute that if you like the idea.
