ceder cladding to timber frame extension, how to fix without it been seen ?

I would appreciate any help we are doing a wrap around ceder clad extension onto a timber frame. The architects have spec'ed 2x1 cedar vertically and then 2x2 cedar alternate throughout. so you get the pattern 2x1 2x2 2x1 2x2. also for shrinkage and expansion what would you guys advise gap between each piece. all help much appreciated.

Can regular bleach be used as an alternative for PCB etching?

I just want to know if there are any chemicals that would be easier to get a hold of than having to go out and buy the ferric chloride or other etchants.

Sulphiric(sp?) acid to etch pcbs? Answered

I am just wondering wether it is possible to etch pcbs with sulfiric acid because I heard it can dissolve copper. But i'm wondering if it will just dissolve the copper or if the entire pcb will melt. ~josh1324

Should I use .032" or .062" copper clad to make my own PCBs?

In all of the tutorials for making your own PCBs, I've never seen the thickness of the copper discussed. Does one work better than the other for home etchings? I plan to use muriatic acid. Side note: does RadioShack still carry copper clad in stores? It's not on the website anymore, and I don't go to RS on a regular basis to check.

Can I use regular printer paper to transfer my design to my copper clad board? And if not, Why?

Im making a printed circuit board for a 555 timer ic and im wondering if using regular printer paper for the toner transfer will make a difference in the quality of the board.

soft circuit- using conductive clay

Hi guys I saw an article on instructables awhile ago about creating conductive/ none conductive clad using simple chemical mix with rice flours, and i think they also post a video on using those clay making a simple toys wired motor and sensors. I was really excited by but the article but forgot to bookmark the page. Can someone point me to the url on this topic? Thanks in advance.

Protoboard Layout Software?

I'm looking for recommendations for good software for making schematics and layouts for protoboard (you know, the copper clad perf board). I've tried expressPCB and looked at Eagle, but they're designed for etching a board - not as helpful as I'd hoped. I want one that allows you to easily create a schematic, generate netlists, lay out your parts, and create connections. ExpressPCB does this, but it is missing something I would really really like - the ability to view the reverse side of the board (for when you're wiring the board). What do you use? Do you like it? What is it missing? Oh yeah, and I don't want to pay anything, either. I'm cheap!

Controversy drives sales - will tabloids never learn?

There's a small family company, BrickArms, which plies its trade online, selling modified Lego minifigs.They are genuine Lego pieces, but modified into (mainly) military garb.Recently, their sales rose so dramatically that they have had to stop taking orders. Not bad, for a company selling individual Lego figures for ten times their originalpurchase price in the middle of a credit crunch.What happened?The media, that's what happened. In the UK, right-wing tabloid Daily Mail found out about the company, and immediately got all in a tizzy because the characters glorify terrorism - they all wear head-scarves or Nazi uniforms. They got a quote from a Muslim and a Jew to say how horrified they were. They got a quote from Lego to emphasise they were not official.They completely ignored half the company's range - as well as Germans and desert-clad figures, they have US marines, a Bond-style secret agent, a Colonial Marine and a zombie-assault set. The figures are meant for diorama-style displays, not to be played with by small children.Things aren't all bad, though - as soon as many readers saw the article, they went straight off to find out where they could be bought. Sales have soared. Even their UK distributor has had to close their ordering systems to catch up.Maybe somebody from BrickArms ought to write a letter of thanks?BrickArms website

Loudspeaker design advice needed. Mini-array Viston FR10 drivers

Hi all, I'm about to get started on my first set of loudspeaker cabinets. Since quite some time I have 8 Visaton FR10 drivers lying on a shelf and I want to use those. After some research on diy loudspeaker cabinets I came up with the design in the attached drawing. Before I start building a pair of these, I'd like to have some advice on the design. I'd like to keep the costs as low as reasonably possible :). Questions I have and some design considerations: - Are the tubes correctly dimensioned? I used the "vented box calculator" over here to get the dimensions for a cabinet with one driver. I doubled the area of the tube and placed two of them in the cabinet. - I plan to clad the inner walls and the backside of the drivers' frame with convoluted foam. Do I need to fill the inner volume with some kind of polyester wool as well? - I want to use the speakers with my "Serious Amp". Will that work? - I planning to build the speakers without a filter. Is that wise? - The four drivers in each cabinet are in pairs series // parallel, to get a joint impedance of 8 Ohm. - As I understand it from the various forums / websites, it's best to place the drivers in a vertical line. However, the cabinet becomes too tall to fit in my tiny livingroom. I just don't have the floorspace to place them. Am I going to regret that decision? Your advice is appreciated! Y.

Update on the layered metal weapons/props

Hello to everyone who took the time to read this update/list. So I have not forgotten about my promise to upload the Solidworks files and cutting plans. However that will be taking a backseat to finals until summer break. I will however go ahead and list off the items finished, in progress, on hold, or currently only in Solidworks form. Finished -6in Axe: 3lb head on an oak clad 1/4in steel flat bar about 20in long total -3in Tomahawk/Axe: 1.25lb head on a para cord wrapped 1/4in steel flat bar about 20in long total -27in BoneSplitter: 3.2lb aluminium reinforced steel construction. -18in BoneCracker: 2lb aluminium reinforced steel construction. -18in All steel BoneCracker: 3.5lb steel reinforced steel construction. More square handle and better center of balance than previous version In progress -10in Bearded Axe: 3.25lb head. To be mounted on oak clad 1/4in steel flat bar handles 18in, and 30in long. -10in blade Pugio: Model made of mild steel for practice and training. Needs to have bevels, and fullers ground plus handle and guard mounted. -8in blade Pugio: Model made of mild steel for practice and training. Needs to have concave edges, bevels, and fullers ground plus and guard mounted. On hold -14in Blade tester: Simple test bed modeled after BoneSplitter to test viability of various band saw blades(Metal and Wood cutting) for use as cutting edge for mild steel blade carriers. On hold due to the band saw blades being too hard to drill through. Only existing as Solidworks files --27in Revised BoneSplitter: 4.5lb Aluminium reinforced steel construction. Better center of mass and more square handle than MY           previous version. --37in blade Bastard sword: Aluminium reinforced steel construction. Should be very close in terms of center of balance and stiffness when compared to its hardened steel companions.  --20in blade Stacked steel Gladius: Twin riveted steel support plates with detoothed metal cutting bands saw blade used for striking edges.  --blade Hispaniensis Gladius: Single piece of metal for the blade. --blade Cinquedea: Single piece of metal for blade. Multi fuller blade. --8in blade Pugio curved: Same as other 8in Pugio except for the convex curved dagger tip --14in blade Spear from Fullmetal Alchemist: May upload the variant of this in which the "wings" are separate pieces of metal. --3.25in square Warhammer: 8.5lb head Assembled from 13 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --5.25 square Warhammer: 16.25lb head Assembled from 21 1/4in steel plates pinned together. Front is covered in 3/8in spikes poking through a steel striking face to prevent separation of the plates. Back end is a 4in spike. --Straight edged War Axe: 7lb head Inspired by Ironclad Industries' Riftclaw. Made from 7 1/4in steel plates pinned together. I am aware that the riveted and pinned construction of these items makes them inherently less durable and less corrosion resistant than single piece construction. However I am a college student who is working with mostly scraps and whatever has to be purchased. Since mild steel thick enough to carve the Warhammers or War Axe is not common scrap material around the college's machine shop the only way to economically create them is to use stacked plate construction. As for the BoneSplitter, BoneCracker, and Bastard sword the stacked plate construction is used to both reduce the weight of the item and stiffen it at the same time.
